Features and Options
Powered sailplane with "Turbo" power system
The most substantial advantages of this power system are its operational reliability, simple engine control and maintenance, an uncomplicated structure and last but not least its low weight. This means that compared with pure sailplanes (the utilization spectrum of which is, of course, widely surpassed) performance penalties are practically non-existent. The "Turbo" propulsion system is primarily intended to overcome dead air conditions and to avoid tedious retrieves - off-field landings may now be safely avoided. Secondly the "Turbo" also makes possible soaring safaris or, for instance, wave exploratory flights from places where launching facilities by auto, winch or aerotow exist. The "Duo Discus T" is powered by a 22 kW SOLO two- cylinder,
two stroke engine which extends/retracts by means of an electrical spindle
drive, assisted by a gas strut. Starter, choke or throttle are not required
- the engine is started by the windmilling effect of the geared- and noise-optimized
multi-blade folding propeller at a speed of about 51 knots and is preset
to operate always at full power. The engine is stopped by switching "off" the ignition and reducing the speed. Once the windmilling prop has stopped, the power plant is retracted regardless of the position of the prop blades as they fold up automatically. Electrical power (12 V) is only required for spindle drive, booster pump and ILEC multi-function engine control unit. On request the latter is also available for the rear seat. Of course the "Duo Discus T" may also be converted any time into a pure sailplane, as the engine with prop and spindle drive are quickly removable (thus saving a mass of approx. 77 lb) - the remaining power plant components are easily compensated by the standard carbon fiber fuselage.
