Jet Engine PBS TJ80-90

PBS TJ80-90 is a small jet engine designed for manned and unmanned aerial vehicles (UAVs) and target drones. Its advantage is its low weight of 12.5 kg including accessories, and thrust of 900 N.
  • Compact design    
  • Excellent thrust-to-weight ratio, low power consumption in the given power category
  • Lubrication with fuel mixed with oil, maintenance-free operation    
  • Electric start    
  • Built-in BLDC starter-generator including control unit (ECU) and inverter

PBS works with the most advanced technology in aviation, facilitating the design and development of world-class single-shaft engines which are among the most well-known and trusted in the field. The PBS TJ80, brought to market in 2018, is an excellent example of the quality and precision required of all PBS products. It is manufactured using 3D technology during the measuring and assembling of the small turbojet engine. 

It is a single-shaft jet engine with a one-stage radial compressor, radial and axial diffuser, annular combustion chamber, one-stage axial turbine and outlet nozzle. The output of the generator is 650 W.

Standard accessories: control system (FADEC), ignition, connecting cable
Optional accessories: electromagnetic fuel valve, fuel filter, control lever, signalling panel, boost pump, reduction valve, converter CAN-RS232, converter CAN-USB, user software

Why us?

Excellent thrust-to-weight ratio

Excellent thrust-to-weight ratio

The thrust-to-weight ratio of any aircraft is an extremely important parameter when establishing the performance of a jet engine as well as the maneuverability of the aircraft. The PBS TJ80 has superb thrust-to-weight ratio due to its compact design and light weight light weight of just 12kg, including the accessories, and a thrust of 900 N. This feature is one of the biggest advantages for this particular small engine.
Excellent engine capabilities during start-up and high-speed functionality

Excellent engine capabilities during start-up and high-speed functionality

The PBS TJ80 also offers excellent engine capabilities such as maintenance-free operation and the ability to startup in any position. There is also the possibility to restart on the ground as well as in flight. There is even a shorter startup sequence, which is under 23 seconds, a huge added benefit to this class of turbojet engine.
