AS 34 Me

Self-Launch Simply Electrically

Complete independence
in a proven 18/15m sailplane,
reduced to the essentials.

Our new entry in the area of independent electric power

This affordable 18/15m sailplane with all its normal quality and safety features, combined with a powerful electrical propulsion system, opens new possibilities for casual pilots and clubs.

An uncomplicated self-launcher suitable for every day use was created by adapting a proven 18/15m sailplane with an unflapped wing to the electrical propulsion system already used in ASG 32 EI. Thanks to the intuitive operation of the engine and the pleasant handling characteristics of the sailplane, it is a pure pleasure to fly at any time.

Proven, efficient high-voltage system
Air-cooled EMRAX motor with 35kW max. and 25kW cont. power output
No additional drag due to completely retractable propeller
Large propeller, matched exactly to the power output
Wing battery with safety case
State of the art safety cockpit

Practicable climbing altitude and range

After the self-launch, a further climbing height of 2200 m (7200 ft) is still available, which results in a range of 125 km (77 mi / 67 nm) using the climb and glide method.

Intuitive, coloured control unit, known from ASG 32 El.

Wing-tip wheels for completely independent self-launch.

15m option available.

AS 34 Me FAQ

Battery informations

Q: What kind of batteries will be installed?
A: 960 Li-Ion metal-clad single cells connected in parallel and in series with a total capacity of 8.6 kWh, divided into 2 battery strings (one per wing) with BMS.

Q: How heavy are the batteries?
A: One battery string weighs about 33 kg.

Q: Can the batteries be removed?
A: The battery strings can be removed relatively easily for replacement or maintenance.

Q: How do I charge the system?
A: The charging port is installed centrally for both batteries in the baggage compartment of the aircraft. The supplied charger is simply connected here. In the disassembled state, the batteries are connected to the fuselage by cables and then charged normally via the charging socket. For this purpose 220 V or 110 V mains voltage is required. Charging current and thus charging time can then be adjusted via the instrument in the cockpit.

Q: How long does the charging take?
A: Shortest charging time at maximum charging current is 4.5h with completely empty batteries.
This is done at 220V with 15 amps drawn from the mains. Reducing the charging current increases the charging time. This reduces the current draw, which reduces the load on hangar installations.

Q: At what temperatures can the batteries be operated?
A: The allowable temperature operating range of the batteries is between -20°C and +60°C.

Q: What is the lifetime of the batteries?
A: The cell manufacturer speaks of 300 charging cycles (charging and discharging is one cycle) before the batteries could start losing power. This is roughly equivalent to 100 engine hours. Which is about 10 years of active use.

Q: Can the batteries deep discharge?
A: No the BMS system of the batteries prevents deep discharge.

Motor system

Q: Which propeller is installed on the AS 34 Me ?
A: The propeller is an Alexander Schleicher development, especially for the AS 34ME. It is a 2-blade fixed pitch propeller with D= 1.2 meters. The lifetime is 1000h.

Q: What is the TBO for the motor?
A: The motor itself, as well as the motor bearings, have a TBO of 1000 hours.

Q: How long does it take to extend?
A: The extension of the propeller tower takes 12 seconds. After that, full power can be called up immediately. The retraction is done from any power by simply pushing the "throttle lever" down. This is fully automatic and takes about 15 seconds, during which the pilot can fully concentrate on flying.

Q: Why do the engine doors not close after the engine is extended?
A: The engine doors remain open to ensure good cooling for the system components.

General questions

Q: How heavy are the inner wings with batteries?
A: The inner wings weigh about 98 kg when the batteries are installed.

Q: What is the MTOW for self launch?
A: The MTOW is 575 kg in 18m configuration.

Q: Will there be a steerable tail wheel?
A: This is not planned so far, since due to the limited battery capacity it does not seem reasonable to use the engine on the ground for taxiing to takeoff. However, wingtip wheels are fitted as standard, allowing easy taxiing in and out of the runway.

Q: What is the difference between the AS 34 ME and the ASW 28?
A: The AS 34 ME is based on the ASW 28-18 with new winglets according to the latest aerodynamic developments, 3-story airbrakes to improve the landing characteristics due to the higher landing mass.

Q: Is there room for tall pilots?
A: The cockpit redesign based on the AS 33 provides more comfort and space for pilots up to 1.95m tall. The cockpit load is between 70 and 115 kg.
