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). The engine may be modified based on customer specific requirements and to meet different operating / installation conditions.

Introduction

The JetCat-P350-PRO-S 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 an electronic control system (FADEC type). The engine may be modified based on customer-specific requirements and to meet different operating/installation conditions.

Functional Description: The JetCat P350-PRO-S 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-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 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 engine’s operation are fully integrated below the engine’s front cowling.

JetCat P350-PRO-S Engine Features / Functions - Integrated Engine-Sided 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, or GSU).
  • Optional bleed-air port (e.g., for pressurization of fuel system).

Key Engine Functions:

  • 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, and remaining fuel in tank.

Advanced Control and Safety Features:

  • Engine/ECU power On/Off via voltage control signal → No external power switches required.
  • Engine safety shutdown input: Flight termination system ensures instant engine shutdown by cutting fuel pump power and closing solenoid valves in a multiple redundant way, while ECU remains powered for continued data reporting and 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.

Additional Features:

  • Automatic fuel purge feature for automatic filling/purge of fuel feed lines. As soon as fuel arrives at the engine, purging will automatically terminate.
  • High-performance ceramic bearings.

With its advanced FADEC system, integrated components, and high-reliability design, the JetCat P350-PRO-S sets a benchmark in propulsion technology for RC-aircraft and UAVs.
