Functional Description:
The JetCat P250-PRO-S-V2 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, a brushless starter system is 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-stage 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 two 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 engine’s operation are fully integrated below the engine’s front cowling.
JetCat P250-PRO-S-V2 Engine Features / Functions:
- 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 at operational altitude.
- 4-pin Molex expansion connector (e.g., for smoke pumps, fuel transfer pumps, or GSU).
- Optional bleed-air port (e.g., for pressurization of the 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 shutdown.
- Reporting of fuel consumed, fuel flow rate, fuel burned, and remaining fuel in tank.
- Engine/ECU power On/Off via voltage control signal (no external power switches required).
- Engine safety shutdown input: Provides instant engine shutdown via flight termination system by cutting power to the fuel pump, closing solenoid valves, and stopping the engine redundantly, while allowing ECU to remain powered for continued data reporting and cooldown.
- Monitoring and reporting of all currents/voltages (supply voltage/current, pump driving voltage) as well as engine life parameters and setpoints.
- Automatic fuel purge feature: Automatically fills and purges fuel feed lines, terminating once fuel reaches the engine.
- High-performance ceramic bearings for long-term durability.
