Strahlturbine 160N Turbo Booster G-160 Graupner 6813 The GRAUPNER G-BOOSTER series of model turbines works in a similar fashion to full-size jet aircraft power plants. Air is sucked into the engine and compressed by a single-stage radial compressor. The air is then mixed with fuel in the combustion chamber and heated by a fuel flame. As the mixture burns, the air mass expands massively and is forced out of the engine, passing through an axial turbine wheel,which in turn drives the compressor via a shaft (cycle effect).
The exhaust gas accelerates to a very high speed (approx. 1000 km / hr) as it leaves the tail end of the turbine, and this produces the thrust required to propelthe model jet.
The turbines feature an electric starter motor and electric kerosene ignition device, making it possible to control the engine completely automatically from the radio control system transmitter. These processesare controlled and monitored by the JETRONIC Vx control unit, which constantly sets all the operating parameters to the optimum values. Auxiliary starting gas, such as propane and butane, is no longer required by this new generation of engines.
All the auxiliary electrical components, i.e. fuel pump, kerosene igniter, starter, valves etc., are powered by a single separate battery.
The GRAUPNER G-BOOSTER series of jet engines features approximately thesame external dimensions and weight as its predecessors, but offers much higher thrust (60 N to 170 N). The latest precision CNC and laser technology is employed to obtain an unprecedented level of manufacturing precision, guaranteeing that the turbines provide high performance and a long effective life.
Each set also includes a display and programming unit (Engine Data Terminal) featuring an illuminated alpha-numeric LCD; it can be plugged in anddisconnected when the engine is running, so that you can read off the current operational data and adjust the settings if necessary.
In addition to the momentary operational data such as exhaust gas temperature (EGT), rotational speed (rpm) and thrust (Throttle), the unit is also able to display statistical data including total turbine running time, rotational speed and temperature statistics, number of starts, battery voltage etc.
A menu control system based on a plain text dialogue is used for all displays and input procedures. The turbine is started fully automatically using the transmitter throttle stick; the pilot then pre-sets the level of thrust he requires using the throttle stick; full proportional control is available. The JETRONIC control unit is connected to the receiving system using R/C 1; R/C 2 is optional, and operates as a switched function. handling a jet-engined model requires the greatest care and considerable technical expertise.
