New PBS Turbojet Engine TJ80M


Our portfolio of turbojet engines for small Unmanned Air Systems, target drones, and missiles continues to grow. We are glad to introduce you new compact turbojet engine TJ80M.


PBS TJ80M is a compact turbojet engine that has been designed for unmanned aerial vehicles (UAV’s). This considerably modified engine builds on its predecessor PBS TJ80 with all its features and improved key attributes.

PBS TJ80M offers the best thrust to diameter ratio in its category. We significantly increased the thrust from 202 lbf to 269.7 lbf (1,200 N) and kept the original outside diameter (9.25 in). The engine weight is 28.21 lb including accessories. The possibilities of ground and in-flight windmill start and restart remain. The windmill starting option offers to start the engine under 7 seconds.

The main advantages of this engine:

  • Compact design
  • Excellent thrust/weight ratio
  • Lubrication with fuel and oil mixture
  • Electric start, possibility of in-flight restart
  • Quick windmill start under 7 seconds
  • Built-in BLDC starter-generator including control unit (ECU) and inverter
