The Prue 215 is an American high-wing, V-tailed, single-seat glider that was designed by Irving Prue in 1949.[1][2]
Design and development
The Prue 215 is an all-metal design with a short 40 ft (12.2 m) wing with a relatively high aspect ratio of 20:1. The wing uses a NACA 23012 airfoil at the wing root, becoming a NACA 8318 at the wing tip. Airfoil-shaped flaps are mounted below and behind the wing for glidepath control. The aircraft uses a retractable monowheel landing gear.[1][2][3]
Three Prue 215s were built, all as amateur-builts from plans. The initial one was Prue's prototype. The second one was built by Ed Minghelli and later owned by Max Dreher, who mounted a jet engine on it. The second and third built are designated 215A.[2][4][5]
Operational history
The second Prue 215 built was flown to second place in the 1958 US Nationals by Harold Hutchinson.[1][2]
Only one Prue 215 remains listed on the Federal Aviation Administration registry.[4]
