Bede BD-2
Role Experimental powered sailplane
National origin United States
Manufacturer Bede Aircraft
Designer Jim Bede
Number built 1
Developed from Schweizer SGS 2-32

The Bede BD-2 was an American experimental powered sailplane designed by Jim Bede to attempt an unrefuelled round-the-world flight.[1]

Development

The BD-2 was a modified Schweizer SGS 2-32 fitted with a specially modified Continental IO-360-C engine.[1] The BD-2 could carry 565 US Gallons (2138 litres) of fuel in wing and fuselage tanks and the modified engine produced only 30hp (22.4kW) during the cruise part of the flight.[1]

The BD-2 made its first flight from Wichita on March 12, 1967.[2] Between November 7-10, 1969 the aircraft set a world closed-circuit flight distance record for piston-engined aircraft, flying undertook a trial flight in which it covered 8,973.38 miles (14,441.26 km) in 70 hours 15 minutes.[3][1] The flight had to be stopped following a complete electrical failure and no further record flights were attempted by Bede.[1]

The BD-2 was modified by Javelin Aircraft of Wichita as the Phoenix, which was used by Jerry Mullens to set a new closed-circuit record for piston aircraft on December 5–8 1981 of 10,070 mi (16207km) in 73 h 2 min, which was also the longest non-refueled flight made by a solo pilot at the time.[4][5][6]
