Bede started the new design by selecting a suitable commonly available engine and then designing the aircraft around it. The selected engine was the General Electric J85, widely used in a variety of military aircraft and virtually identical to its civilian counterpart, the General Electric CJ-610, available both in new-build and second-hand ...
[1] [2] Flight testing resulted in modifications to the engine cowling and ailerons. [1] In July 2018, the Ascender's Superior XP-400 engine suffered a crankshaft failure which resulted in the aircraft ditching in a lake in Alaska and sinking. The aircraft was subsequently recovered and, after two years of repairs, flew once again with a new ...
Bede Aircraft Company has since re-formed and has been working on several new designs. Before his death in 2015, Bede hinted at a two-seat tandem version of the aircraft, called the "Super BD-5", using a certified aircraft engine and a number of modifications and improvements, but nothing more than a preliminary design drawing was made available.
That aircraft was destroyed in June 1964 when a welding incident in the garage caused a fire. The aircraft had accumulated 145 hours of flight testing by then, and his wife persuaded Dyke to build an improved version as the Dyke JD-2 Delta. [4] Its first flight was on 18 July 1966, [5] and across 40 years it accumulated over two thousand flight ...
Flight testing revealed that the aircraft was impossible to stall. The pilot and single passenger sat side by side beneath an expansive canopy , and the undercarriage was of fixed, tricycle type. Durand sold 75 sets of plans by 1987, and by that time, at least five aircraft (including the prototype) were known to be flying.
While the Long-EZ, originally designed for the Lycoming O-235 108-118 hp engine, was closer in the design of the Berkut, the latter was designed from the outset for the larger Lycoming IO-360 180 hp engine. The aircraft was later adapted, with a different engine mount, cowls and battery location, to accept the 260 hp Lycoming IO-540, which most ...
The resulting federal standards on design, engineering, stress analysis, use of aircraft-quality hardware and testing of aircraft brought an end to amateur building except in some specialized areas, such as racing. In 1946 Goodyear restarted the National Air Races, including a class for aircraft powered by 200 cubic inch and smaller engines ...
The design of the P-70 Acey Deucy was started by former United States Navy Commander John C. Powell in 1966 with construction commencing in 1967. It was certified by the Federal Aviation Administration in the experimental homebuilt category and the prototype first flew on 20 June 1970. Following testing the design was sold as plans for ...
