TheJongblood Primary is an American single-seat,high-wing,strut-bracedprimary glider designed byMike Jongblood of southernCalifornia and first flown in 1967. The aircraft is unusual in that primary gliders went out of fashion in the 1930s and few have been built since.[1][2][3]
Jongblood designed and built this primary glider in 1966, with assistance from Hugh Knoop. The design was original and includes an originalairfoil design as well, designated as aJongblood II section.[1][2]
The aircraft is built from wood and covered in dopedaircraft fabric covering. The glider has a detachable pod to cover the pilot or can be flown open cockpit. It has a constant chord wing with a 4 ft (1.2 m) chord and a 32.5 ft (9.9 m) span. The wing features dual parallelstruts andjury struts, but has nospoilers or other glidepath control devices. Thetailplane is alsostrut-braced. Unlike most earlier primary glider designs that land on a fixed skid, this aircraft has a fixed monowheel.[1]
Only one was ever constructed.[1]
The Primary had accumulated over 200auto-tows and sevenaerotows, along with nine hours of flying time, by the end of 1968 and by 1983 had flown 22 hours total. It had flown a single three-hour flight and had recorded a height gain of 8,000 ft (2,438 m).[1]
By 1983 the aircraft was reported as being in storage. In May 2011 it was still on theFederal Aviation Administration registry listings, although itsregistration had expired on 31 March 2011.[1][2]
