As UAVs, experimental aircraft and high-performance RC jets continue to develop, propulsion systems need to provide high thrust without adding unnecessary weight or installation complexity.
An 85kgf turbojet engine offers a practical balance between thrust, size and system weight for aircraft that require more power than small micro turbojets but do not need a larger 120–150kgf engine.
EN-P85 85kgf Turbojet Engine
En EN-P85 is a compact turbojet engine designed for UAV propulsion, RC jet aircraft, experimental aviation and turbine research projects.

The engine combines an integrated ECU and fuel system with a compact Ø202 × 479 mm structure, simplifying installation for different aircraft platforms.
Why Choose an 85kgf Turbojet Engine?
High Thrust in a Compact Package
With 85kgf of nominal thrust and a total system weight of approximately 11 kg, the EN-P85 is designed for applications where propulsion performance and weight efficiency are both important.
Simple System Integration
The integrated ECU, fuel pump and fuel valve reduce the number of external components required during installation and help simplify the overall propulsion system.
Flexible Applications
An 85kgf turbojet can be considered for:
- Fixed-wing UAVs
- High-performance RC jets
- Experimental aircraft
- Propulsion research
- Aviation technology demonstration platforms
85kgf vs. Smaller and Larger Turbojets
Choosing an engine should not be based on maximum thrust alone.
A smaller 40–60kgf engine may be suitable when aircraft weight and fuel consumption are the main priorities. A 120–150kgf engine may be more appropriate for larger aircraft with higher thrust requirements.
En 85kgf class provides a middle ground, offering substantial thrust while maintaining a relatively compact installation envelope.
What Should Buyers Consider?
Before purchasing an 85kgf turbojet engine, aircraft developers should evaluate:
- Aircraft takeoff weight
- Required thrust margin
- Fuel capacity
- Engine installation space
- Operating altitude
- ECU compatibility
- Supplier testing and technical support
- OEM or customization requirements
The best propulsion system is not necessarily the engine with the highest thrust. It is the engine that matches the aircraft’s weight, aerodynamic design and operating requirements.
