Infos techniques | Charge alaire minimale : 35,8 kg/m2. Existe aussi en version 15 mètres. LAK-17B is new version of LAK17A. Regarding A version, B has new wings with modified geometry and new wing profile, which allow even higher wing loadings than competitors. Fuselage and tail section is identical like A version. The creators of Front Electric Sustainer ( FES ) are Luka Znidarsic and Matija Znidarsic, both experienced sailplane pilots and mechanical engineers in Slovenia. Front refers to the motor’s location, right in the nose of the sailplane. A 1 meter carbon fibre propeller automatically extends when the outrunner is operating. When not in use, the propeller blades fold against the nose of the sailplane thus reducing drag. Each blade weighs just 240 g. The Znidarsic's developed their own brushless DC synchronous permanent magnet electric motor and controller for the application which is light, small and mounted on top of main whell box. The motor is 7.3 kg (16.1 pounds), and puts out 22 kW (30 horsepower) at 116 Volts. Total weight for the power package is 45-50 kg (99-110 pounds), with Kokam lithium-ion batteries in two packs ( each behind the rear spar, balancing the weight of the motor and propeller in the nose ). | ||||||
