TCF study #12
 

  • Skid  WingSled™ (from Omega Hang Gliders)   . Put a surface that will not catch; carbon fiber plate.
  • Frontal canard that actually has a trailing edge just aft of the basebar, so skiing the bottom surface of the canard wing over rocks and plants will protect the pilot. The canard wing will be made of composite carbon fiber CCF and be held by a sturdy carbon beam from the leading edge of the main wing.
  • Downwind downslope .... pilot with skis on his feet.  How could one off the skis at the last moment if one wanted street shoes for the landing.   If one is committed to stay in the pod, then how might skis come into sturdy place when standing vertically.       The canard might be best.
  • If there is 15 mph plus tailwind at landing in an 18 mph wing, then the ground will be moving at 33 mph when the canard will be hitting rocks and plant as a broad ski; this will slow the system, but still there will be the 15 mph tailwind that could catch the trailing edge and flip the wing
  • Extended keel to skid 
  • If canard WingSled™ (from Omega Hang Gliders)  is being used, then a see-through aft-section of the sled could give visual ; the aft part should go as far as under the TCF basebar, so that the plants and rocks will not pop up and catch the basebar.
  • If I am coming in with tailwind and the rocks and plants are streaming by at 30 mph, then skiing of the legs without catch will be important. Firm knee protection! Clear all snags. Lower section of the harness should sled also.
  • Will the canard have two settings? For for flight and one for landing?
  • No beaking
    Fold down a portion of TCF forward to become skid
  • When the sledding is occurring over the rocks and plants, the bracing will be on the control bar and pulling the front flying wires; so beefy frontal flying cables will be important.
  • In a tailwind landing, a final keeping nose up could keep the wind from flip trail-edge over top.
  • Last minute restraining pilot to the aft cable; have lines left and right to harness that go to aft flying lines; a mid cable hookin will be available; this will keep pilot from flying too far forward if a sudden whack or stop is experienced.
  1. Downwind downslope landing of hang glider ....what to do?  If the slope is steep, then fly downwind with extra airspeed and then use that energy to fly out and make a turn to do a quick upslope landing into the  wind.
  2. GS will be wind speed plus flying airspeed in a tailwind landing.   Do keep flying; keep up airspeed no matter that the ground is going by fast. Things will be OK if the texture of the ground is OK and some preparations are made for this kind of landing. What could those preparations be?  
  3. The trip from TCF feet is the challenge. Even if there were wheels at the feet, they are in a place that does not solve, if the wheels are low tread and the texture of the landing is with sand,  rock, or plants that would catch the basebar and bring rotation of nose to a beaking.  Small wheels do not keep the basebar up away from stones and plants. Plants and rocks can hit the basebar and trip the glider into beaking.   Ball, turn, and ?
  4. Idea fuzzy: quick shortening of the hang lines.
  5. Idea fuzzy. Hang line that stretches without rebound, but takes up energy when stretched.
  6. What is wanted in one tactic for downwind downslope or even just downwind level is to ski over the irregularities of the ground while flying.  Tailwind downslope.
  • Prove the solutions with FLG  flatland long gliding ...
  • Practice with solutions, so that the fast groundspeed thing is familiar.
  • Desert plants are a challenge. The Joshua tree is high and most troublesome.     Could I map out clear-enough areas in non-road areas?   Wheels for hiking out will be wanted. Could wheels be stowed in the harness backplate? Or could wheels be wrapped from battens?  Or drag on ski?
  •  
  • Frontal low skid. Look at primary gliders and powered aircraft. HGs should not be different.
  •  
  • WWW    Wheels When Wanted
  • BRWW Big roller when wanted.    But if the canard sled is used, then rollers and wheels will not be needed.
  • Frontal low skid that could ski over plants.
  • Split TCF so that the frontal split rotates forward
  • Catch net pulled up from TCF basebar hold to fill the triangle of the frontal wires.
  • Harness body to rear of keel to prevent full swing through.
  • Quick harness shoulders to the two feet of the TCF to prevent full swing-through. The holds could be energy-takers that let some swing-through with non-rebound stretch; that is, no springback, just stretch with a taking up of energy. This might be pneumatic compression with release of air from leak as a piston in the special cord compresses air but releases at a certain rate. Or a one-way bungee that ratchets to prevent rebound.
  • Tet  with  lower face ....too sharp....such could dig in......rather, the broad canard wing would be much better. Broad canard would press down plants and skip over rocks. A sharp delta canard could cut into plants and get caught or dig into ground and plow or enter between rocks and wedge. Differently, I want to ski over plants and ski over rocks.

  • July 9, 2010, sent a note in Facebook to Dave Kilbourne about my working on small low canard to do several functions:   Lift, front downwind downslope skid, anti-whack, and other secondary uses.
  • Posted note in July Lift 2010.
