PBS TJ80M – modified turbojet engine designed for UAVs
The newest member of the PBS aircraft systems family is a modified propulsion unit, the PBS TJ80M turbojet engine. The latest modification features an increase in the engine's thrust by one-third, from 900 to 1,200 newtons, and a reduction in the specific fuel consumption, while the weight and outer diameter of 235 mm have remained unchanged.

PBS TJ80M is based on PBS TJ80 introduced in 2018, which provided a 900 N thrust in a relatively small body. The result of subsequent development programs of the engine is the modernized
PBS TJ80M. Modification of the compressor stage, axial turbine, and fuel system significantly improved the engine parameters.
Within the frame of this project, a new spark plug of only 18 mm height was developed. The smaller installation dimensions make the engine integration easier. A new control algorithm has been implemented in the ECU, which allows full use of the engine's thrust potential depending on the flight altitude.
Furthermore, PBS TJ80M is a 100 % "ITAR-free "propulsion unit, which makes it a great choice for a wide range of unmanned aerial applications. The "M" version represents the first stage of the modernization program of the PBS TJ80 jet engine. PBS will direct its development activities to further thrust increase and introduce a saltwater version of the engine for landing in saltwater and subsequent reuse.
