Twenty-nine days later on August 6, Peterson landed at Hilton Head, South Carolina. Peterson, Jr., took off in a Fledgling from Long Beach, California. With his Fledgling, McCornack hoped to match this enthusiasm with an ultralight airplane that almost anyone could purchase and fly. Technological advances in low-cost and lightweight airframes and power plants during the 1960s and 1970s ignited public enthusiasm for a new kind of minimalist aviation. Jack McCornack, president of Pterodactyl Limited, developed the Fledgling by adding landing gear, an engine, and other improvements to the rigid wing Manta Fledge hang glider.

IIIF provides researchers rich metadata and image viewing options for comparison of works across cultural heritage collections. All flight speeds and all the different positions of the flaps refer to a generally good control and manoeuvrability behaviour of the Archaeopteryx and gives a feeling of safe flying to the pilot.Usage Conditions May Apply Usage Conditions Apply There are restrictions for re-using this media. The very harmonic and not tiring control behaviour is the result of a careful tuning optimization considering the effects and loadings of each rudder. The highly efficient fullspan flap and the airbrake are controlled by a lever located on the left handed side. Ailerons and elevator are controlled by the pilot with a right handed stick, the rudder with pedals. ControlsĪ conventional control mechanism is implemented in the Archaeopteryx basically used as in all common planes. A landing gear with a low touch down speed complete the safe landing procedure. The slow landing approach velocity and its effective airbrake allow a small spread landing approach on hang-glider sites. For all the different flap settings it shows a very friendly stall characteristic, avoiding dropping and risks of spinning during straight and curved flight manoeuvres. The around all axis aerodynamically contolled wingflap glider is flown like a conventional sailplane with comparable characteristics of flight, fight behaviour and controls. The takeoff speed of the Archaeopteryx is far less compared to common rigid wing hang-gliders and includes stability advantages of the longitudinal axis. Propertiesīesides the main launching method by foot, alternative methods like bungee, car-towing, winch-towing and aerotow using microlight vehicles are possible. Besides, the concept includes a high performance in fast and uncritical gliding as well. Excellent climb rates and an efficient riding out of extremely weak and slim thermals (microlift) are possible. Primary targets were set to minimize the mass, allowing slowest possible flight speeds and providing good manoeuvrability based on a friendly stall behaviour. Here is a description of the Archaeopteryx from the builder's website: ConceptĪ conventional aeroplane layout was followed for the Archaeopteryx, to avoid well known problems of flying wings. The Archaeopteryx is equipped with flaps, allowing for the performance necessary for a foot-launch. The design is intended to be foot-launched, car-towed, aerotow-launched, or with some other assistance. The Archaeopteryx is a foot-launchable ultralight glider being designed and built by ZHW (now Ruppert Composite) Archaeopteryx Archaeopteryx by Ruppert Composite
