P250-Pro-S Turbine Engine Set with Kerosene Starter, by JetCat

The JetCat-P250-PRO type turbo-jet engine is designed as a propulsion unit for RC-aircraft and/or drones. The engine is lubricated by fuel with oil admixture. The engine is equipped with a BLDC starter), 1x BLDC fuel pump, 2x fuel solenoids and electronic control system (FADEC type).

JetCat P250-PRO-S RC-Set including:

• 1x JetCat P250-PRO-S (71152-0270)
• 1x Turbine Mounting Clamp (41152-0248)
• 1x JetCat PRO-Interface (61168-0010)
• 1x JetNet (61128-0052)
• 1x Remote Controller GSU V2.0 (61101-0010)

The JetCat P250-PRO is a single-shaft engine comprising a single-stage radial compressor, annular combustion chamber, single stage axial turbine and fixed exhaust nozzle. At the compressor intake, there is a brushless starter system mounted. Intake air is compressed in the radial compressor stage, proceeds through the radial and axial diffuser into the combustion chamber where it is mixed with vaporized fuel. Combustion gases generated by fuel burning in the combustion chamber expand through the single state axial turbine and the exhaust nozzle to the atmosphere. The gas exiting the exhaust cone produces the required thrust. The rotor of the engine is mounted on 2 ball bearings lubricated by a fuel/oil mix.

Control options / electrical interface
The JetCat-PRO engine series provides the highest level of integration and maximum ease of installation. All peripheral systems necessary for the engines operation are fully integrated below the engines front cowling.

• Integrated Engine Components: ECU (electronic control unit), fully programmable via detachable Ground Support Unit (GSU)
• Brushless starter and seal free brushless fuel pump
• Fuel & Kerosene-start solenoids
• Post Fuel filter downstream of the pump (last barrier filter)
• Barometric altitude / pressure sensor allowing for automatic engine tuning upon operation altitude.
• 4-pin Molex expansion connector (e.g. for smoke pumps/ fuel transfer pumps/GSU)
• Optional bleed-air port (e.g. for pressurization of fuel system)
• Direct quick start on kerosene via integrated high speed / low current ignition system
• High altitude, high flight speed in-air restart capability
• Automatic engine cool down cycle after shutting down.
• Reporting of fuel consumed / fuel flow rate / fuel burned / remaining fuel in tank
• Engine/ECU power On/Off via voltage control signal  No external power switches required
• Engine safety shut down input, for instant engine shut down via (flight) termination system. This will kill power to fuel pump and shut off safety solenoid valves and stop engine in any case on a multiple redundant way, whilst ECU can stay powered on (for continued data reporting and or engine cool down).
• Monitoring and reporting of all currents / voltages (e.g. supply voltage / current, pump driving voltage) as well as all engine life parameters / setpoints.
• Automatic fuel purge feature for automatic filling/purge of fuel feed lines. As soon as fuel arrives at the engine, purging will automatically terminate.
