Elbert Leander Burt Rutan (born June 17, 1943 in Estacada, Oregon) is an American aerospace engineer noted for his originality in designing light, strong, unusual-looking, energy-efficient aircraft. ... Scaled Composites (often abbreviated as Scaled) was founded in 1982 in Mojave, California by famous aircraft designer Burt Rutan out of what used to be the Rutan Aircraft Factory. ...

Development

The prototype Defiant, N78RA, first flew on 30 June, 1978. It was intended as a proof-of-concept of a very safe light twin design, requiring little trim change and no pilot action in case of engine failure, and with good single engine performance. A comparison of the Defiant single engine climb rate with a Grumman Cougar showed about 390 vs 280 ft/min at low altitude with both aircraft cleaned up. The prototype is now owned by the Hiller Aviation Museum. is the 181st day of the year (182nd in leap years) in the Gregorian calendar. ...

The Hiller Air Museum, located in San Carlos, California at the San Carlos Airport, is an aircraft history museum. ...

In 1979 the Rutan Aircraft Factory announced they would proceed with certification of a Defiant-based light twin. Adequate financing was not secured for this project, and the design was modified for homebuilt construction as the Model 74, with the second aircraft (built by Fred Keller) appearing at Oshkosh 1983. Plans were offered in mid-1984. Nine examples were known to be flying as of mid-1987. Nineteen are registered with the FAA as of 2005.

The Lycoming O-320 is a normally-aspirated, air-cooled, four-cylinder, direct-drive engine commonly used on entry-level aircraft such as the Cessna 172 and Piper Cherokee. ... VNO of an aircraft is the V speed which refers to the velocity of normal operation. ... The maximal total range is the distance an aircraft can fly between takeoff and landing, as limited by fuel capacity in powered aircraft, or cross-country speed and environmental conditions in unpowered aircraft. ... In aeronautics, the service ceiling is the maximum density altitude where the best rate of climb airspeed will produce a 100 feet per minute climb(twin engine) and 50 feet(single engine) at maximum weight while in a clean configuration with maximum continuous power. ...
