Let The Jet Engine Take You Home.

The jet engine provides the Ventus-2cxaJ with a small, handy sustainer engine system that can is easy to operate, yet small and light. All Ventus-2cxa can be retrofitted with this system.

This snappy and agile racing machine has been rigorously adapted to the demands and requirements of ambitious competition pilots. Thanks to the optionally available short 15 m outer wings, flying in the FAI 15 m class does not require any compromises.

With the Jet sustainer engine, Schempp-Hirth offer another save way to return home  besides the Turbo sustainer system (developed by Prof. Oehler) - and one that matches the specific requirements of a competition pilot.

Small & Light.

The incremental weight of the jet engine motorization is only a few kilogramms. Because of the compact method of construction of the Käppeler system in combination with the jet engine PSR-T01 it is possible to install the engine system and the corresponding fuselage tank into a Ventus-2cxa. In this minimal configuration, the engine range is still sufficient to reach a near-by airfield in powered flight. If your don’t need any further range, you will get an engine system with an unbeatably small weight, but optional wing fuel tanks can increase the maximum range.

Fuel and Power Requirements.

The jet engine requires a mixture of kerosine (JET A1) and a special oil. The electrical power for the jet engine is provided by a separated battery with its own circuit.

Easy Operation.

Jet engine operation is very simple thanks to the mostly automated JET Engine Control Unit that prevents operator errors: The extension and start of the jet engine, which was tested up to a speed of 100km/h, is triggered by a single switch; engine performance is controlled by a knob. The JET Engine Control Unit is monitoring all important engine parameters and prevents overrevving the engine.


The engine thrust is available over the full authorized speed range. So the Pilot can choose between a maximum rate of climb like with the Turbo engine system (from Prof. Oehler) at a speed of approximately 95 km/h or a horizontal flight at a speed of approximately of 150 km/h.

After shutting down and cooling down, the engine is automatically retracted.

If required, the engine can be dismantled in a few simple steps and you can fly the airplane as a pure glider.

More Space and Better Visibility.

The completely revamped fuselage has longer overall fuselage length and a newly designed, larger tail optimized for the 18 m wingspan. The cockpit has a slightly longer design and can now accommodate pilots up to 1.9 m height. The new, drag reduced fuselage is also 2 cm wider, offering more leg-room and generally providing more room where needed. Even tall pilots will find ample space in this fuselage.

The canopy rim is cut back, allow better all-round vision for more safety. To further enhance comfort and safety, the fuselage now has a suspended, 5 inch aluminum wheel with a superior working disc brake.


In cooperation with Dr. Karl-Heinz Horstmann (wing geometry, airfoil) and Prof. Mark Maugher, PhD (new winglets), the outer wing has been completely redeveloped. Following concurrent reviews of the design and test results, an optimally tuned outer wing and winglet could been created.

The proven tail units from the Ventus-2ax/bx models with the low drag airfoil from Prof. Loek Boermans and the advantageous double trapezoidal geometry of the elevator were further optimised by extending the tail's span to suit the new 18m wing.

The Ventus-2ax and Ventus-2bx are very light gliders. With their modern carbon-fibre wings, their multi-stage swep-back leading edge and (removable) winglets and the further refined wing airfoil (13.1% chord), they have been designed as optimized FAI-15m-Class racing machines without compromises.

This snappy and agile racing machine has been rigorously adapted to the demands and requirements of ambitious competition pilots. Thanks to the optionally available short 15m outer wings, flying in the FAI 15m class does not require any compromises. 

The Ventus 2cxa is not only for competition pilots, but for any pilot who loves consequently optimized technology and maximized technical potential.

Besides the jet-based sustainer engine, the Ventus-2cxa can now also be ordered with the innovative, silent and environment-friendly Front Electric Sustainer system. This system has the electric engine and the foldable propeller installed in the nose of the fuselage, while the two 16kg batteries are safely stored in a compartment in the fuselage behind the wings.

Combining top performance with most pleasant flight characteristics, the Ventus-2cx provides the base for unforgettable gliding experiences. To fly it is simple and safe, it climbs above average even at high wing loads and can is easy to handle both in the air and on the ground. Not without reason, the Ventus-2cx can always be found in top OLC positions and is top of its class when flying in high mountains.

Handling and agility of the Ventus-2cxT have set standards; top positions at championships and the OLC prove its performance. The turbo sustainer system, proven for decades, adds the assurance that the risk of landing out and the burden of long retrieval tours are a story of the past.

The combination of the versatility of using a Ventus-2cxT and the easy usage of its engine make it the ideal piece of sports equipment for competitions or ambitious cross-country flights, the perfect companion for soaring safaris - or simply the robust favorite glider of any gliding club.

If you are a sporty pilot and you are looking for a self-launching glider that is handy and agile, has a sophisticated and proven engine system that you can hardly notice when gliding, there are few alternatives to the Ventus-2cxM in its class. The automated engine control ensure safe handling and foolproof operation, but does not take control and influence out of the pilots hands.
