convex undersurface for hanglider useing ski battons

[skeatesy]

by the use of flat ski battons of carbon in the bottom surface convex shape is maintained without the battons spinning in their pockets to lower the camber for higher performance ... skeatesy

update.. alternative to convex ski battons is triple surface foam insert with a mid batton truss and top battons which can be modified for 40% to 100 % triple surface so beginners can use topless gliders with high glide ratios just by adding a percentage of foam undersurface convex triple surface

suspension in hangliders allows the yaw to track perfectly and handling of the tip wash out uses a swing arm connected to the keel with a rear wire rubber band to allow the anheadral to flex as well as reflex roach with a dive stick

another experiment flattens the tip wash out with out stall problems is to ballance the tips by plates and swivels so the forward section of the tip jutts forward past the leading edge ' to 140 degrees but dosent violate the 130 degree nose rule because the rule applies to swivel angle realy not the leading edge angle wrongly assumed' ,swivel and aerodynamicaly ballances it self so a flatter tip wash out results with a mass ballance and a flexable add on tip to reduce vortecies

1970's hangliders can be updated and cheap with todays experimental technology and still get to cloud base with only 6/1 lift drag values off your local hill and reduced complexity

130 nose gliders with tails and flaps and wide nose angles with cannards as alternative ideas in hangliders

130 degree nose angle controls the lift centroid created by the luffing action movement inwards to the keel from the wing tips and it must atall times travel faster than the gliders speed forward and always arrive ahead of the c/g so the incidence will activate behind the c/g if it is not virile enough the incidence will be imputant and the glider will be divergent but if the nose angle is wider only a cannard can sustain stability and virility of the lift centroid movement and keep it ahead of the c/g .... in the case of ridgid wings the materials help tp absorb the incorrect nose angle and partialy activate the incidence since most ridgid wings wings are wider than 130 nose angle and this nose angle is realy a swivel angle and the way the luffing washout momentum is accumilated and heads towards the inner fuselage so an aircraft to be safe must crachk ahead of the c/g and not behind which many aircraft do and so when the auto pilot cannot keep up with the oscilations the aircraft crashes and the pilot is blaimed but piaggio have a triple tandem wing wihich has a cannard and a tail to maintain stability and stop tail slides ....skeatesy
