Welcome
Draline announces the launch of a new revolutionary, product on the sailplane market, the PSR Jet System.
New sailplanes can be equipped with this system and it is also possible to retrofit a sailplane with the PSR Jet System. It allows a glider pilot to extend the range of the plane and this auxiliary engine significantly reduces the risk of "outlandings" and increase the ability to fly to regions that cannot be reached without auxiliary engine power. You can use this auxiliary engine to climb and switch it off after your sailplane has gained sufficient altitude. When not actually in use during flight, the PSR System can retracted it into the glider's fuselage. The system consists of an instrument panel with control switch to turn it on and off, as well of a box that will retract the engine into the fuselage, when not operating. Information on engine rpm, fuel quantity, exhaust gas temperature, ready to start indication, is shown on the control panel. Dralines PSR Jet System is, in many ways, advantageous over traditional 2 stroke engines and the following, benefits as shown below, are introduced, based on our research and the way glider pilots value the features of the PSR Jet System. The PSR Jet System will be built- in by distributors, which will have the TC or STC of your sailplane and it will have the following strong benefits: Retrofit-able One of the great advantages of the PSR Jet System is the ability to retrofit the PSR Jet System into sailplanes that are not prepared for the attachment of auxiliary engines from scratch. This is a feature that provides essential value to pilots. For structural and design reasons it is currently not possible to retrofit certain gliders with an auxiliary piston engine, such engines being considerably larger and heavier than the PSR jet system. Safety The entire PSR Jet System is very small and thus leaves room for other systems, such as parachutes. Furthermore, the design and size of the PSR Jet System does not cause critical aerodynamic disruptions during the retraction phase (which can lead to a sudden loss of height and speed). Reliability of auxiliary engines is an often discussed criteria. Pilots indicate a high need for reliability, since a failure of the system during flight could lead to an emergency landing outside of appropriate airfields. Despite the high-tech nature of the PSR Jet System and its retraction mechanism, the PSR Jet System is highly reliable. Overall, reliability, space and the aerodynamic design of the auxiliary engine and therefore safety on the whole are major benefits for glider pilots. Performance The lighter weight and in turn improved performance are two further benefits of the PSR system compared with bulkier and heavier piston engines and the engine has a virtually constant thrust throughout the glider's speed range. The PSR Jet System produces less in-cockpit noise and is totally free of vibration during operation. Innovation Another important advantage that the PSR Jet System can deliver is certainly the light weight of the whole system, including the retraction mechanism, a fraction of current glider auxiliary engines thus retaining the performance of the sailplane. The electronic control unit will make the start-up and shutdown sequence easy, just by turning a switch. Engine operation, including start-up, running and shutdown is managed entirely by the electronic control unit.
