The Jeffair Barracuda is a high-performance sporting monoplane that was developed in the United States in the 1970s and is marketed for homebuilding. Designed and built by , the prototype won the prize for "Most Outstanding New Design" at the EAA Fly-in in 1976.[1] It was a low-wing cantilever monoplane of wooden construction with retractable tricycle undercarriage and side-by-side seating for two. Around 150 sets of plans had sold by 1977.
Development[]
Geoffrey Siers was a former RAF pilot and engineer for Boeing in 1967. He set out to design an aircraft that was fast, aerobatic, two place, and had range to fly long cross-country flights. The aircraft was refined after a full size cockpit mockup was made. The lightweight construction of the plywood-covered wooden de Havilland Mosquito was the inspiration for the materials choice. The retractable landing gear came from a Piper PA-24 Comanche. The wings were a three-piece design[2]
Operational history[]
Test flights were performed in 1975. The aircraft takes off at 70 mph (113 km/h) and climbs at 2000 feet per minute (10.2 m/s). Full flap stalls were recorded as low as 54 mph (87 km/h).[3]
