The Bede BD-4 is an American light aircraft, designed by Jim Bede for homebuilding and available since 1968. It was one of the first homebuilt aircraft to be offered in kit form. [ 1 ] It remains one of the world's most popular homebuilts with thousands of plans sold and hundreds of examples completed to date.
The BD-3 is a six place, low wing pusher configuration aircraft with tricycle landing gear. The aircraft is powered by two engines driving a single shrouded pusher propeller connected with V belts and overriding clutches. The aircraft uses STOL Boundary layer control devices. The fuselage was built using aluminum honeycomb. Bede intended to ...
It can be fitted with an engine between 45 and 80 hp (33.6 to 59.7 kW). The prototype had a 60 hp (45 kW) HKS 700E two-cylinder four-stroke engine. [ 1 ] The pilot has an enclosed cockpit with a rearward-sliding canopy.
Bede Aircraft Corporation was founded by aeronautical engineer Jim Bede in Cleveland in 1961 to produce the BD-1 kit aircraft, which eventually became the American Aviation Corporation's AA-1. The company also created and produced a number of advanced kit planes including the famous Bede BD-5 ( pusher propeller driven) and BD-5J (turbojet driven).
There was an attempt to sidestep the engine problem with the BD-5S glider (S for Sailplane), with lengthened wings and no engine, which prompted Air Progress magazine to sarcastically note, "At last, a BD-5 with no engine problems." [citation needed] This glider version did not fly well and the project was scrapped. Some work on a BD-6 was also ...
The aircraft was intended to be offered with a variety of new or rebuilt engines. Rebuilt engines were to be available to reduce the purchase price. Design powerplants included the Continental A65-8 of 65 hp (48 kW), Continental C90-14F of 90 hp (67 kW), Continental O-200 A of 100 hp (75 kW) and a Lycoming O-235 C1 of 108 hp (81 kW).
The BD-5's failure was due largely to the unavailability of a suitable engine; during the BD-5's history one engine company after another either exited the engine business or went bankrupt. Bede started the new design by selecting a suitable commonly available engine and then designing the aircraft around it.
This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe.
