The tricycle landing gear is steered by differential braking and a castering nosewheel. The company estimated that an average builder would take 120 hours to build the aircraft from the assembly kit. [1] The standard engine recommended is the two-stroke 40 hp (30 kW) Rotax 447 and with this engine the standard empty weight is 252 lb (114 kg). [1]
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. [citation needed]
The Affordaplane (sometimes written Afford-A-Plane) is an American plans-built, high wing, strut-braced, single engine, tractor configuration, conventional landing gear equipped ultralight aircraft for the US FAR 103 Ultralight Vehicles rules. Designed by Dave Edwards, it is intended for amateur construction. [1]
For commercial jet aircraft the jet noise has reduced from the turbojet through bypass engines to turbofans as a result of a progressive reduction in propelling jet velocities. For example, the JT8D, a bypass engine, has a jet velocity of 400 m/s (1,450 ft/s) whereas the JT9D, a turbofan, has jet velocities of 300 m/s (885 ft/s) (cold) and 400 ...
The General Electric I-A was the first working jet engine in the United States, manufactured by General Electric (GE) and achieving its first run on April 18, 1942.. The engine was the result of receiving an imported Power Jets W.1X that was flown to the US from Britain in 1941, and the I-A itself was based on the design of the improved Power Jets W.2B, the plans of which were also received.
In its standard configuration, the aircraft is a true double-delta with no horizontal stabilizer; however, a small T-tail is an option for trimming variants with higher-power engines. Since the mid-1960s, designer John Dyke has sold full construction plans and three-view drawings for the aircraft to homebuilders and is still selling them today.
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.
The Bearhawk LSA is a "clean sheet design" inspired by the larger Barrows Bearhawk. The LSA features a strut-braced high-wing, a tandem enclosed cockpit accessed by doors, fixed conventional landing gear and a single engine in tractor configuration. The cockpit is 31 in (79 cm) wide.
