Default [3e] Bede BD-5J Microjet

Bede BD-5J (TL7)
Holding the record for the world’s smallest jet, the BD-5J was designed by the father and son team of James R. and James A. Bede. The younger Bede wanted to bring aviation to enthusiasts by creating easy to assemble kit planes. The -5J required about 600 man-hours to assemble. The company did very well for 17 years, but ultimately could not complete with copycat competitors. In the early 1990s, James Bede tried to reestablish his presence in the market, but was killed in a test flight of the BD-10, another micro-jet that appears similar to an F-15.
A BD-5J was used in the opening scenes of the James Bond film Octo*****.

Design Notes:
The Body is 60 cf with Super-Light frame and Expensive materials. It has Very Good streamlining. Mechanical controls. The Wings have a historical area of 37.8 sf; this translates to a volume of 3 cf. Wheels are 3 cf. Armor is Expensive metal. Design loaded weight was off by ˝ lb., however, loaded weight can vary from 700 to 1,100 lbs. Design stall speed was 65 and design aSpeed was 307 mph. The real-world values are shown above; landing and take-off run values are also real-world.

The BD-5B was the initial version of the kit, and was powered by a 51-kW engine and propeller. Wing area was 47.4 sf, wing span was 21.5’; aSpeed 200, Stall 59.
