      Modern hang gliding remains active in a wide spectrum of activity. 

      GH, the one-point focus is a bit tight.        And about the triangle control bar or A-frame: Such was in a battened flex-wing hang glider cable-stayed and with pilot hung from keel ... in the first decade of 1900s. 

      Here is just part of modern hang gliding: 

      Niche Hang Glider Activity
      Self-Soar Association (S-SA) embraces all hang gliding niche activities on earth and beyond earth.   
      The WHGA and WPGA are associated with S-SA.   The FAI CIVL handles some specialized sport activities.

      People are grouping, communicating, and forming activities with specialized foci, applications, and purposes.  Involvement choices are extensive.  In each activity, the highest regard for proving safe operations is recommended. If a strong online group is not yet formed on your selected activity, consider running a group...and sending us your link.

      1. Discern how you will be participating in hang gliding; there are many ways and means!

      2. Discern why you will participate the way you will.

      3. Service?  Personal?  Commercial? Leadership? Supplier? Manufacturer? Avocation pilot? Competitive sports pilot? Author? Photographer? Communications? Inspection? Repair? LZ manager? Instructor? Promoter? Fan? Illustrator? Club officer? Driver? Meet volunteer? Researcher? Reporter? Test pilot? Test engineer? Test technician? Ground-school instructor? Retailer? Dealer? Celebration volunteer? Site seeker and negotiator?

      4. The ground is very hard.

      5. Newton's laws will apply to you.

      6. Learn all you can; keep safety at the top of actions.

      7. Manage risks at each moment.

      8. Keep situationally aware.  Others, traffic, weather, equipment, self fitness, ...

      9. Adjust reviews and practices in relation to how frequently you fly.
         

      10. Use the buddy system (be sure your buddy shares the safety and awareness habit!).
         

      11. Important, yet minority:  It is possible to fly a hang glider you make by yourself or with your buddies. You could build without spending a dime by using only materials from the trash. Or you may spend a million dollars to get the wing and situation you want.  Some take high joy in incremental iterative tinkering on new-for-them flight system designs that they or others will test and fly.  Some will aim to invent and modify hang glider systems and parts.  Others will aim to become manufacturers.  Some will live 24-7 embedded in hang gliding activities. 
         

      12. Choices, styles, slants, preferences, interests, emphases: You might choose to purchase a hang glider and put all of your time and attention on flying. Some choose to fly only what they themselves build. Others know that they would not ever trust their own handcrafting. Study as much as you can; receive instruction in disciplines that will be used in your chosen activity and applications; keep a journal/flight log; reflect; be smart, patient, cooperative, wise, respectful, circumspect, communicative, and ever open to considering critiques by others. Know what has been done well and safely; know and learn from the craft and body injury incidents that have occurred. Inspect, check, practice; master what is needed for your particular hang glider activity. Consider written explicit well-organized checklists. Have fun again and again and again ...  
        Read Red on getting started.     

        Recall that FAI  will adjust itself once a niche sporting activity reaches their radar. That is, feel free to follow your truth, even if no one else is yet in your room.  Your joy will be attractive. Grow the winging ways you wish.   What are you dreaming?  Recall that hobby, experimenting, play ... need not react to FAI sporting. Staying in play, hobby, and experimenting are traditionally strong avenues of creativity and recreation.  Your flight log and birdman journal may be sacred scriptures.         JpF

      Super-Modernized Standard Rogallo Hang Glider SMSRHG
      moving the Charles Richards wing template (stiffened Rogallo wing)  with the 1908 cable-stayed triangle control frame into using advanced materials and safety tweaks, yet retaining the four-boom foldability and sharp nose angled airfoil for limited applications.
      Fully limp governable ram-air inflated hang gliding founded on the Domina Jalbert mechanical invention. Much of "paragliding" is here, as term is used in 2000s (not 1960-2 where the Charles Richards wing--that mechanically essentially topped the "standard Rogllo hang glider" was called "paraglider" then...So, it will be a point of confusion if a 2008 paragliding pilot came upon the literature of 1961 in NASA. )..
      Bus hang gliding (BHG).   Efficient carry-on-city-bus hang glider packs (framed-controlled sorts) are the coin of people doing bus hang gliding. They ride buses to and from flying sites.
      Pos-inflate PG   piPG   These wings are string-controlled yet have positively-inflated wings with pressure adjusters.

      Patent parade      Gain lift from following, understanding, identifying, mining, etc. the claims made in the world of kite patents, especially how such directly relates to hang gliding (primarily a kite system).
      Foot-launchable powered glider. FLPHG, FLPAircraft, FLPSailplane  Power source specializations are occurring: electric, electric-solarinternal combustion engine ICE, jet and JetBugpower-beaming, solar-electric from power-beaming, laser power-beaming, etc.   Fuel, batteries, ultracapacitors, remote beamed energy, etc. are being considered. Purposes vary: training hops off flatland, barely soarable one-lift, returnable lift-assist units, long-session soaring sustaining, landing-choice expansion and assurance only, inaccessible launch solution, foot-launch race coursing, and more. 

      Some have an eye to the fusion future. Energy densities guide development. Hybrids that derive energy from more than one source are being explored. Add pilot power at different stages is a fun sector of these efforts. Clubs, groups, collaborative efforts, and competitions are being explored. Early pioneers trying compressed air were generally disappointed at the energy density of compressed air. 

      When HG beams (spars, TCF, ribs) resolve to be nearly 100% double-purposed parts (mechanical structure so formed to be at the same time an electrical-charge storage device), then further advances will be made. More: When all exterior surfaces of the HG and its system parts (harness, helmet, sail, etc) are electric-charge makers using ambient light as energy source, then breakthrough performance is envisioned. More: When nanotech materials churn near magic on these solutions, then control, thermal sensing, gust advantaging, and low-mass will bless hang gliding.  The opening of millions of launch and landing points is part of the eventual outcome of these efforts.

      Foot-launchable sailplanes.   These craft tend to be heavier than hang glider; and foot-launchable sailplane invite the use of aerodynamic controls. The weight of these will continually be reduced as nanotech materials come into play.

      Span-wise rotary-wing HGs. (a few types and arrangement styles). 

      Types to distinguish:

      • 1. Single fixed wing,  Toys, ship sails, boat sails, signs, confetti,
      • 2. Split left and right wings with open center.  Toy gliders have occurred. Kites have occurred.
      • 3. Very different: cyclogiro. Very challenging... 

      This niche sector has very few adherents. Glide ratio is very low, but  the low L/D can be significant for specialized hang gliding purposes.  The rotating wings challenge designers and users.  "Sweet spots" of design and use for recreation hang gliding seems to have evaded experimenters so far. Surrounding this sector: Fan wing, Magnus-effect gliders, Magnus-effect governable parachutes, top-to-back rotating rectangles of slightly S-curved paper, Magnus-effect rotary kites, and more. The elliptical leading edges here can also play; stability and control challenge, and anti-spin is a concern.  Landing has its challenges.

      Biplane hang gliders   There are many variations on the biplane theme. Watch for specialists that seem to stay refined over one branch of biplane hang gliders. For example, the Hang Loose replica people are focused on Lambie's Hang Loose and are not paying attention to the Chanute replica biplane. Double-surfaced airfoils may be the focus of one communicating group of hang gliders; others will aim for single-surface airfoils. Some will aim at using tensegrity for trussing. Others: inflatables.  Others will be just on Otto Lilienthal replica biplanes. Others will aim for polishing the Boy Mechanics plans.   Others will aim to use modern composites to the nth degree.

      Flatland long gliding hang gliders. FLG  Here true flatland is used for running the wing. Then by skill, one gets longer and longer glides. Think of long jump of Track & Field athletics.

      Zenithal-HAT hang gliders. Here a control surface is zenithally above the main wing; canard or tail is replaced by the HAT or high airfoil "thing". Though Lovejoy's High Tailer was not quite a ZHATHG, such inspired one designer to the ZHAT to replace canard or tail.     Near: See "high hats" thread in OZ Report.

Note that the glider pilots will always (thankfully) be on the upwind side of the stench. 

      Hang gliders set with kinetic and visual flight simulators. Specialists give an increasing number of people a vicarious hang glider flight experience. Pilots also get training in such simulators.
      Human-power input to hang glider flight system.  Here people aim at using human power in various way in hang glider flight systems. One focus is human effort to tow. Another is to use human effort to recharge batteries or ultracapacitors during fliking  or XOHG or pre-flight pauses. And more. The succes of HPA continues. The advance toward soaring HPA is part of the challenge with respect to hang soaring. Daedalus.

      Cross-ocean hang gliding:  XOHG  This realm is futuristic despite the various crossing of water that have been done. The challenge is cyclic launching to soaring from the water surface with stabilize gear. Many schemes are being considered. Anne Quemere is paving some way toward these matters.

      Anne's effort's intersection with hang gliding?
      1. One day fliking across the Pacific and Atlantic oceans in hang gliders will occur. Anne did kite across the Altlantic; now she is taking a bid on the Pacific Ocean. She is tracing paths that will be helpful in planning the hang gliding fliking trips. The logistics of her efforts will hold gems for those who will pioneer the cross-ocean hang gliding flikes. 

      2. The example of kiting across oceans has a strong impact on some hang glider planners. 

      3. The kites Anne is using are rooted in Domina Jalbert's invention of ram-air inflated airfoil. One format for crossing the oceans by hang gliding may be the same type of wing, probably modified so that landings on the water with the hang glider wing will provide positive retained flotation; thus a combination of ram-air inflation and positive kept inflation may be part of the successful hang gliding solution. However, another considered format for the hang gliding solution very well may be a high-performance air-beamed hang glider flight system that will be able to self-kite off the water surface in repeat cycles while being able to reel-in all of its own self-kiting gear (de-powerable water anchoring chute) somewhat like Jack Lambie suggested for land fliking in Ground Skimmer after a set of self-kiting methods were described in Low & Slow and also in Richard Miller's Without Visible Means of Support in a dual-kite dynamic-soaring system. 

      4. Anne with her boat Oceankite (its name) is hung below her wings. Though she is not "falling" as in hang gliding, her drag and inclinations in the fluid water provide relative to the wind a net thrusting that lets her travel. This is a close cousin to hang gliding and for some this whole matter teases the advance of the skills and materials that will permit independent cross-ocean hang glider fliking. 

      5. Anne's showing non-fuel use of the wing that is iconic in hang gliding's paragliding sector will bring increased familiarity to the iconic wing. This matter is suspected to make the world more at home with the PG space and thus also hang gliding space as PG is a subset of hang gliding. 

      6. Already there is a theoretical examination started that compares the speed that might be obtained by cross-ocean hang gliding flikes compared to Anne's kiting methodology. Will hang gliding cross-ocean fliking occur faster or slower than Anne's kite-sailing method?

      Expectation notes: Hang gliding across oceans is expected to be done with landings on the water where the pilot will sleep and care for other survival tasks. It is expected that there will be many up and down cycles to achieve the crossings. Solo yes, but there will also be two-person hang gliding crossings. There are several types of hang gliding crossings expected: a) Self-kiting launches; b) Powered-assist launches with power provided by storing energy from pilot, wave, wind, sun, hydrogen-from-water-sun. The challenge of materials is high, as the salty and wet environment will beckon advances and high care. Staying safe while asleep on the water's surface will attract high sophistication in environmental awareness and communications. The hang gliding challenge will draw the best that science and technology will bring. 

      Wishing Anne the best in her present bid to cross the Pacific Ocean by kite ! She launched on the day of a political breaktrhrough in the USA as she kited beneath the Golden Gate Bridge. As the Statue of Liberty was a gift from France, I see Anne Quéméré as a gift to kiting and hang gliding.

      Solar-energy-assisted-launch hang gliding. These people aim at launch assist by converting the sun's radiation to drive a launch motor. Many varieties of specialized means  are here.
      • Specializations within this sector.
        • The hang glider itself has surfaces that convert the sun's energies.
          • The motor is carried throughout the flight.
          • The motor is released for glide back after soaring altitude is reached.
          • Sustaining soaring by use of in-flight solar-recharge and direct solar-energy use.
        • Batteries or ultracapacitors are recharged from ground-based solar-conversion devices.
          • Motor is carried throughout the flight.
          • Motor is released for glide back to club center after soaring altitude is reached.
        • Power-beaming. The hang glider's motor is powered from energy received from a set of power beams from ground or aerial devices.
        • Corded launch assist. The hang glider is connected by electric cord that stays connected during the launch. The cord might ride up a balloon tether as the glider climbs in a circle. Once altitude is reached, the cord may slide back down the balloon tether for use by another club member. 
        • Scooter towing launch of hang glider could receive power from solar energy recharge.

        The above is not at all complete. Related: Larry Maurro, Solar Riser, "Sunseeker flew from California to Kittyhawk," electric hang glider, electric aircraft, Electraflyer (consider recharging by solar means), solar-charged electric drive,  Explore: Eric Raymond

        Futurism: Every surface exposed to direct or indirect light of hang glider system is double-purposed so that no net mass is costed for having solar-energy conversion occurring to charge ultracapacitors (which themselves are structurally double-purposing, so that again no net mass is costed for having energy storage. Then have optimized electric motor and optimized propeller. Use the system to launch off any spot on earth...land, water, building roof ...to get to soaring altitude. Soar. Be collecting solar energy during soaring. Use the stored solar energy to sustain soaring, to return to home, to quickly clear sink, to assure landing area reach, to cross oceans, to flike, to achieve effective trekking.  The ultracapacitors double-purposed will last a lifetime. The nanotech construction will be UV resistant and last a lifetime. Ultra lubricants in seal motor will have low friction cost. And more. Send in your ideas:  Editor@...

      Competition hang gliding using purchased hang gliders from  Former HGMA Members or Current HGMA Members   The HGMA is the second or so. The first included others, like Omega Hang Gliders.. 
      See: Markowski's Hang Glider's Bible.    For example, Davis Straub is a competition hang glider pilot.

      Competition sport hang gliding via FAI classes.

      Morphable wings have inroads to most niche sectors of hang glider activity. However, there are those who specialize in morphing means. Variable billow and variable geometry are mechanical principles known in early aviation. But modern tactics and materials are opening a host of new opportunities for morphing wings during flight.

      Communications with cousin activity groups:   Specialize in tracking and communicating with PWCA, CIVL, NACs, clubs, associations, etc.  and with leaders of niche hang gliding activity.   Maintain databases, glossaries, archived copies of correspondence, photographs, plans, manuals, etc.  There is room here for many persons around the world.  Perhaps organize and spread the tasks among cooperating persons. 
      • Accident and incident collecting.    
      • Interface with cousin activities
      • Finding references
      • Work to feed correcting references in order to sharpen hang gliding history. The fuzzy realm of history is ever full of positive opportunities to correct statements, improve understanding, make more clear something.    For example, local excited tinkerers often claim mechanical global invention over something when they are only finding for themselves something that was already globally invented; honoring the local excitement while bringing forward the richer history is an exciting niche activity taken on by some as a hobby or profession.

      le vol du Zeppy 2/2  This is operated mostly at neutral buoyancy and is thus not with any major role of gliding up or gliding down. Its shape is not for the gliding.    However, in 1944, Domina Jalbert's patent had flexible wings on a buoyant keel that would give good gliding up or gliding down, depending on the buoyancy set.  Water gliders are especially using the principle of changing from positive to negative buoyancy for gliding up or down. Major commercial gliding airships are being proposed. There will be a niche association of recreational users of alternating-buoyancy hang gliders.  See:The Gravity Aircraft  And then consider hybrid hang glider.

      Make me fly   More of a non-hang-glider role ...  But consider if shape and/or wings were applied for gliding up when more buoyant and gliding down when net weight is heavier-than-air. When role is for gliding up or gliding down, then design changes.

      Cable Hang Gliding     http://getaway.ninemsn.com.au/article.aspx?id=17475

      Nano   Some people are deciding to focus on bringing into hang gliding advances from nanotechnology, nano-machines, nano-materials.  Some of our community occasionally visit this discipline; others are working diligently to find how nano-chemistry, nano-physics, and nano-design might bless hang glider flight systems.  For example, when one finds "A carbon nanotube is capable of transporting cargo and rotating like a conventional motor" in the literature, then one might deeply search for ways such matters might affect one or more aspects of hang gliding.

Intensity and profundity can be gamed in many ways in such a scenario. Bob Bendetson, well positioned script writer, has about 12,000 such flights off a mere 6 to 7 m slope and claims to enjoy the activity immensely to good personal benefit. A very long list of skills are open for strong mastery in such a scenario. He also stores a second hang glider for his flights in the thermal Sylmar site.

      Urban-trash hang glider. Enthusiasts require that their hang glider is constructed only from ambient urban found trash.
      Education-based hang glider: High school class project. Specialists form lesson plans that involve mathematics, history, materials, safety, low-mass construction principles, physics, weather, aerodynamics, communications, etc.
      Authoring    Ever good articles are needed to enrich the many facets of the hang glider universe. Take a topic and explore it to the point where you generate an article that will bless all. There are thousands of hang glider topics needing fresh attention by a caring researcher.
      Mechanical Invention    The challenges in the hang glider world invite further mechanical invention. Huge sectors of mechanical invention are yet to be discovered that will bless the hang glider world.
      Ornamental appearance design invention (distinguish from fundamental mechanical invention which is very different). 
       End products ever need to be polished for appearance. Ornamental design tinkering that uses the mechanical inventions of others is an important hang glider world activity that makes pleasant the various hang gliding activities.  For instance, the cable-stayed triangle control frame for hang gliders was mechanically invented at least by 1908 clearly, but probably before.  But the ornamental design of belly bars, streamlined bars, particular finish, tweaked sizes, etc. for appearance change are important. Take what was mechanically invented and polish the appearance of the item, subassembly, or full assembly. Recommended: Credit the mechanical inventors that may be involved in the function and principle upon which your ornamentation lives. Notice that active protection of mechanical invention beneath your invented appearance invention could require legal respects before a functioning product of your appearance design could be commercialized. In turn, if you gain a sharp ornamental appearance patent that sells the eye of consumers, then you could prevent an underlying mechanical inventor from using the particular appearance ornament that you have found.  Trade in good spirits and win.

      Foundational activity!  The evolution of hang glider sails is not a done deal. Advances keep showing their heads here. New methods of making sails, new materials, and new functions of the sail keep this activity sector open for innovation and polished skills. Threads that are themselves solar-energy converters are tickling the future of hang gliding. Dynamic soaring via smart gust utilization will be affecting  HG sails. Smart nanotech films will be changing hang gliding. Mass production methods continue to evolve as hang gliding becomes a foundation for many practical applications.
