Diamona HK36

 

The H-36 Dimona side-by-side two-seat motor glider was designed by Wolff Hoffmann, who left Scheibe to form his own company, Hoffmann Flugzeugbau, to put the Dimona into production at Friesach in Austria, where production was due to start in the summer of 1981. Design work began in 1979 using the Worthmann FX63‑137 wing profile. The all-fiberglass two-place self-launching HOAC (formerly Hoffmann) Dimona features a folding wing design which allows two people to fold both wings in several minutes and reduce the aircraft hanger space requirement to no more than that of a sailplane trailer. The Limbach engine drives a Hoffmann 2 blade, 3 position propeller. Of glassfibre construction, the Dimona is a low wing monoplane with a T-tail and a fixed tailwheel undercarriage with spats on the main wheels. The wings can be folded alongside the fuselage and are fitted with air brakes. The cockpit canopy hinges upward for entry, and there are two rear windows. The 80hp Limbach SL2000 EB1 'flat four' engine drives a Hoffmann three-position two blade propeller, and a special engine suspension is featured to ensure low noise and vibration levels.
 
The prototype made its first flight on 9 October 1980, on sale since summer 1981; some 50 Dimonas had been ordered by the spring of 1981.
 
The Hk 36 Super Dimona has the wing span increased to 16.2 m. with carbon fiber spar and modified fuselage. It is also offered with wingtip extensions to give a span of 17.6 m. Approach control is with top surface Schempp-Hirth type airbrake. In addition to the Limbach, it is offered with a Rotax 912 A of similar power, or a more powerful Limbach L 2400 EB. Dimonas have been manufactured in Germany and Austria, and is Air Transport Certified.

 

The two-place self-launching glider, a development of the HOAC HK 36 Super Dimona, is produced in four varieties, the HK 36TC with an 60 kW/ 81 bhp engine and tailwheel landing gear, the HK 36TC with the same engine and tricycle gear, the 86 kW/ 115 bhp HK 36TTS with tailwheel gear, and the HK 36TTC with the same engine and tricycle gear. The variants with the larger engine have the capability of towing lighter sailplanes. The wings fold back to stand vertically parallel with the fuselage for storage.
