Our expert technicians at PBS have designed and developed the PBS TJ40-G1 turbojet engine within the small turbojet engine category for small aircraft such as gliders and some larger model aircraft.
The engine has been the recipient of a prestigious award at the 2015 IDET exposition in the Czech Republic due to its many advantageous characteristics. It has an extremely compact design, with all accessories integrated within the engine body (excluding the fuel pump). It is also very a light weight of only 3.4 kg, and a maximum thrust of 395 N. The start-up sequence is advantageously short at less than 25 seconds and there is an easy and rapid kerosene starting system. The PBS TJ40-G1 can restart from the ground as well as in-flight and has unilimited starting position angles.
The PBS TJ40-G1 small turbojet engine is a single-shaft 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 150 W. It is slightly more compact than the TJ40-G2, which is measures just 69 mm longer
than the PBS TJ40-G1.
