The Lange Antares 23E is a single-seat, self-launching glider of the Open Class with an electric drive the company Lange Aviation .
history
The Antares 23E was developed from the Antares 20E . Thereby we cooperated with Schempp-Hirth Flugzeugbau , who offer the aircraft in a similar configuration, but with a conventional combustion engine, different fuselage and different outer wing than Schempp-Hirth Quintus .
construction
drive
The drive system of the Antares 23E is based on a brushless 42 kW external rotor electric motor, which draws its power from lithium-ion batteries .
accumulator
The batteries are integrated in the wing. In a cold environment, the battery is heated to achieve full performance. According to the manufacturer, the battery life is 3000 charge cycles, then 80% of the capacity is still available. Regardless of this, the battery must be replaced after approx. 20 years. Since this type of battery is also used in American military programs, it can be supplied until 2031 according to the contract.
Structure
The structure was designed in collaboration with Loek Boermans and designed for particularly variable surface loads. It has a wing with a super-elliptical floor plan and nine different profiles. The flap can be moved to -3 ° in high-speed flight. There are winglets at the ends of the wings . The wing flaps are designed as flaperons . Three-tier Schempp-Hirth airbrakes are integrated into the wing to make landing easier.
