Turbine engine PBS TJ80-120
The PBS TJ80 engines are compact sub-sonic jet engines specifically designed for UAV systems, including target drones, remote carriers, unmanned combat systems, and other disposable aircraft. They feature excellent thrust-to-weight ratio, with a thrust of 900 – 1,200 N and a weight of 12.5 – 13 kg.
They are a single-shaft turbojet engine equipped with BLDC starter-generator, electric fuel pump and electronic control system. They are lubricated with a fuel-oil mixture, and they generate 650 W of power through their integrated generator. The engines may be customised by adjusting the length of the exhaust pipe.
The PBS TJ80 engines feature capabilities such as ground and in-flight start and restart, along with saltwater recovery. Additionally, the engines enable quick windmill starting and maintain operational envelope limits suitable for air-launched applications, with a maximum altitude of 10,000 m and speed of 0.9 M.

Turbine engine PBS TJ40-G1
The turbojet engines of the PBS TJ40 family are specifically designed for small aircraft within the small turbojet engine category, such as target drones or loitering munition. They feature a compact design, low weight, and the thrust of 395 – 425 N.
The PBS TJ40 are a single-shaft engines equipped with a one-stage radial compressor, radial and axial diffuser, annular combustion chamber, one-stage axial turbine, and outlet nozzle. They are lubricated with fuel oil mixture.
The PBS TJ40 engines stand out for their easy and fast start, and repeatable ground and in-flight restarts. These attributes, combined with the compact dimensions of the engines and their capability of saltwater recovery, make them highly suitable for UAVs and similar applications.
