Pettier PA 15-34 Kit-Club
CARMAN JP 15-36 Aiglon
The Aiglon (Eaglet) was a private venture design by CARMAM's technical directors Robert Jacquet and Jean Pettier, and is a restricted Standard Class sailplane; design work began in September 1971, and the prototype made its first flight on 14 June 1974.
Series production began in 1976, the first production JP15-36A making its first flight on 16 October that year; a version with a retractable monowheel and provision for up to 121 lb of water ballast is designated JP 15-36AR.
The single-seater Aiglon is intended for intensive club use and so special attention has been paid to good flying qualities and safe landing characteristics for not-so-experienced pilots. Construction is of glassfibre, the cantilever mid wing having a single glassfibre spar and a glassfibre/Rohacell/epoxy sandwich skin and steel-tipped wing tip 'salmon' fairings. The ailerons are of plastic and can be operated either differentially or in unison, and there are Schempp-Hirth air brakes on the upper and lower surfaces; for ease of wing rigging the aileron and air brake controls are designed to connect automatically. The semimonocoque glassfibre fuselage is moulded in two halves and joined at the centreline, a single bulkhead forming the cockpit backrest and a shock-absorbing structure for the monowheel. A large one-piece canopy gives excellent visibility, while both seat and rudder pedals are adjustable in flight: on the JP 15-36A the monowheel s fixed and has a cable brake, and there is also a tail bumper. The swept back fin is integral with the fuselage, and the wooden rudder is fabric-covered, the all-moving tailplane is of plastics construction.
The Pettier PA 15-34 Kit-Club homebuilt version is essentially the same as the JP 15-36A but with some structural simplification and redesign to make it more suitable for amateur builders; the glassfibre wings are factory-made. Plywood-covered spruce construction of the fuselage and tail unit replaces the Aiglon's more sophisticated glassfibre structure, although the Kit-Club's nose-cone is of glassfibre. The tail boom, rudder and rear part of the tailplane are fabric-covered, and there is a fixed unsprung monowheel, with a cable-operated drum brake on production aircraft. The change to wood construction results in only a slight weight penalty, the maximum weight going up to 926lb, and performance is very similar to the JP15-36A's. The prototype Kit-Club made its first flight on 6 November 1976, and 12 had been built by December 1979. The Kit-Club is also available in factory-built form from CARMAM.
By January 1980 a total of 39 JP 15-36Aand JP 15-36AR Aiglons had been sold.
The CARMAN JP 15-38 Standard Class single seater utilises the same wings as the JP 15-36A Aiglon with provision for 220lb of water ballast; these are married to a new fuselage of similar construction to the JP 15-36A, which has a mechanically retractable unsprung monowheel. Instead of the Aiglon's low-set tailplane the 15-38 has a T-tail, with elevator and spring trim.
Construction of the 15-38 began in February 1977 and the prototype made its first flight on 17 June 1979.
