The Schempp-Hirth Arcus is a flapped Two Seater Class glider in production by Schempp-Hirth . It first flew 7 April 2009. It is offered in addition to the Duo Discus which is an unflapped 20 metre two-seater, whose fuselage it shares. The wings have flaperons integrated along the whole span.
4-590: It is available as a pure glider, a turbo using the Solo 2350-engine, and as a self-launching glider using the Solo 2625-02i. An electric power unit based on Antares 20E equipment was produced until end 2016 when cooperation with Lange stopped. Data from Schempp-Hirth. General characteristics Performance Related lists Antares 20E The Lange Antares is a glider built by Lange Aviation produced with three different wingspans, 18, 20 and 23 meters. The 20 and 23 meter variants can be equipped with
8-402: A 42-kW electric motor and SAFT VL 41M lithium-ion batteries . The EM 42 is a fixed-shaft brushless DC electric motor running at 190-288 V, and drawing up to 160 A, the 42 kW motor can deliver up to 216 N.m of torque over a speed range of 160-1600 RPM with a total efficiency of 90%. Maximum continuous power is 38.5 kW, the motor weighs 29 kg, and the weight of power electronics
12-683: Is 10 kg. The motor turns a two-blade fixed-pitch propeller , LF-P42, constructed of composite materials, having a diameter of two meters. The battery system consists of two battery packs positioned in the leading edges of both inner wings (72 cells divided into 24 modules containing 3 cells each). The battery life is expected to be 3000 cycles or 20 years. The capacity of the battery is 41 Ah ( specific energy 136 Wh/kg and specific peak power 794 W/kg). The batteries can deliver 13 minutes at maximum power and maximum climb speed, and can climb 3,000 meters on one battery charge; in reality, in warm climates, motor and electronics temperature limitations can limit
16-467: The achievable climb height. The charger is integrated inside the fuselage so when landing elsewhere the pilot merely has to find a (16A) electric outlet socket. The glider has a modem connected to its main computer so that Lange technicians can, in theory, run diagnostics remotely. The same modem allows the pilot remote control & monitoring of the battery charging process. The undercarriage and engine doors are electro-hydraulically operated. The tailwheel
