The Lange Antares is a glider built by
Lange Aviation
Lange Aviation GmbH is a German company that manufactures gliders and develops electric power-plants for other aircraft. It was founded by its present managing director, Axel Lange, in 1996 as Lange Flugzeugbau GmbH in Zweibrücken. The company cu ...
produced with three different wingspans, 18, 20 and 23 meters. The 20 and 23 meter variants can be equipped with a 42-kW electric motor and SAFT VL 41M
lithium-ion batteries
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. Li-ion batteries are characterized by higher specific energy, energy ...

brushless DC electric motor
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings, p ...
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 is 10 kg. The motor turns a two-blade fixed-pitch

A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working flu ...
, 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
Specific energy or massic energy is energy per unit mass. It is also sometimes called gravimetric energy density, which is not to be confused with energy density, which is defined as energy per unit volume. It is used to quantify, for example, st ...
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 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 is steerable. The wing has an elliptical planform, with winglets and wing-tip wheels. The glide polar shows excellent high speed performance.
