Turbojet Engines

PBS AEROSPACE is specialized in production of turbojet engines. Production of turbojet engines is a significant category in the field of aircraft engines. The advantage of turbojet engines is the ratio of their weight to their highest achievable output.  Because of this, these engines are used in particular in the military industry and they are popular in the experimental sector. In recent times, in a period of an increase in the use of unmanned aircraft, they are often fitted to this type of equipment, particularly in the military industry. In this category, PBS AEROSPACE has designed, developed, manufactured and brought onto the market several smaller turbojet-type engines. More than 530 produced PBS turbojet engines power unmanned systems, drones, powered gliders and experimental aircraft worldwide. Today,  the turbojet engine TJ 100 belongs to the 4TH GENERATION of this type of power plant. PBS AEROSPACE Inc. (US) supplies the complete range of these engines in the USA.

The TJ 100 is a 4th-GENERATION turbojet engine. The TJ 100 is especially suitable for unmanned aerial vehicles (UAV). These can be used by rescue services or for police or reconnaissance purposes and also for other assignments and missions within military applications. These engines are also ideal for gliders and light sports and experimental airplanes. The TJ 100 engine is of a compact design and has an excellent power-to-weight ratio of up to 292 lbf (1,300 N) with low fuel consumption for its output category. This engine is also suitable for landing on water.


The TJ 40 is a turbojet engine designed for UAV systems, such as target drones and decoy drones, in order to confuse enemy air defenses and small reconnaissance drones. It has the advantage of having a weight of only 7.16 lb. (3.25 kg)  and a thrust of 88.8 lbf (395 N).

The TJ 20 is a small turbojet engine designed for UAV systems, such as target drones and decoy drones, in order to confuse enemy air defenses and small reconnaissance drones. It has the advantage of having  a weight of only 4.37 lb.  (1.98 kg)  and a thrust of 47.2 lbf (210 N). It comes with electric starting, a fuel pump and a sparkplug built into the casing of the combustion chamber – the ideal components for UAV systems.
