Hang glider flight9/6/2023 ![]() ![]() ![]() Spratt well instructed the triangle control frame for hang gliders the triangle control frame for aircraft had already many versions, even used in the collapsed form on the gyrocopter that Dickenson had copied from Benson. The pilot sat on a swinging seat hung from the airframe as had been done on many hang gliders since the 1900s and made use of a 1908-at least- triangle control frame to push/pull for enhanced weight-shift control the triangle control frame had been in aviation since at least 1908 as cable-stayed like Dickenson later used, as well as strut-stayed by others also earlier Barry Hill Palmer had reached a similar solution but trussed as Gottlob Espenlaub in 1921 in 1929 George A. Australian Mike Burns later attained a water-ski SkiPlane that released to gliding flight later yet John Dickenson, in 1963, fashioned a water ski kite with a wing hardly distinguishable in detail from what was findable on one of the Paresev 1B kite-glider machines that used the stiffened Rogallo airfoil in a construction designed by NASA Charles Richards under the lead of Francis Rogallo's promotions and models developed in teamwork from 1958 to 1961 when Paul Bikle gave a directive for Charles Richards to build a glider quickly and cheaply along the lines Rogallo had exampled. Rogallo's wing's simplicity, ease of construction, capability of slow flight and its gentle landing characteristics did not go unnoticed by hang glider and ultralight glider enthusiasts, like Barry Hill Palmer who built seven to eight versions of foot-launch hang gliders with up to four distinct control strategies Palmer may have been the first to build and fly a Fleep-like or Paresev-like stiffened Rogallo wing hang glider. The flexible airfoil and its full spectrum of stiffenings were tested by NASA as stearable parachutes, parawings, paragliders, kite-hung-payload gliders, and manned hung-pilot kited hang gliders in free-flight for the aimed purpose of space capsules' return to Earth and some images of these tests were published in the early 1960s by NASA and by some aviation magazines. On 1948, aeronautical engineer Francis Rogallo invented in 1948 a self-inflating wing which he patented as the flexible wing, also known as the Rogallo Wing. Controls systems developed for powered craft were also adopted in hang gliders like wing warping by the Wright brothers in 1902 and subsequently of aileron control by the French. The hang glider lost in relatve importance through the emphasis on powered flight. The first recorded controlled flights in hang glider were by German engineer Otto Lilienthal who published all of his research in 1889, influencing later designers. ![]()
