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 7.94 lb, and a maximum thrust of 96 lbf. 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-G1NS 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 2.72 in longer than the PBS TJ40-G1.
