PBS TJ150-The New Turbojet Engine from PBS Velka Bites

By Editor 21-Mar-2018


Czech aircraft engine manufacturer PBS Velka Bites, a.s., has developed a new aircraft turbojet engine, PBS TJ150, to cater to the needs of missile and UAV markets. With its in-house expertise in design, development, production and testing, PBS continually works on new engine development in order to meet missile and UAV market requirements. This year PBS has finished the development of its new turbojet engine PBS TJ150.

The newly developed engine PBS TJ 150 has been derived from PBS Velka Bites’ most commercially successful model of PBS TJ 100 turbojet engine (1,300 N thrust). It is a single-shaft engine composed by a starter generator integrated in the radial compressor impeller, one axial turbine, autonomous oil system and digital control system. So far, almost 800 units have been delivered to customers.

PBS is a producer of jet engines in the power range from 200 to 1,500 N. The company also produces a range of gas turbine auxiliary power units end environmental control systems mainly for small helicopters and trainers.

PBS Turbojet Engines

PBS turbojet engines have proven to be efficient propulsion units in hundreds of aerial targets, UAV and UCAV systems, powered gliders and piloted micro jets, mainly in Spain, China, Russia, UAE, the USA, France, Germany and other countries.

With an excellent power-to-weight ratio, compact design, reliable operation, low fuel and oil consumption, and starting at high altitudes and at high speeds, PBS jet engines stand out from competing engines.

New development PBS TJ150

Weighing just 19.6 kg and 272 mm in diameter, the engine PBS TJ150 offers 1,500 N thrust. It features an integrated starter-generator with 600 W electrical power output and is controlled through full-authority digital system FADEC. The engine can operate at speed up to 0.9 M, ambient temperature of -50 °C to +45 °C and altitudes up to 9,000 m. It has an ability of ground and in-flight restart up to 4,000 m and at maximum speed 0.6 M.

PBS Turboprop and Turboshaft Engines

PBS is also a manufacturer of turboprop and turboshaft engines designed for MALE UAVs, unmanned helicopters and small experimental aircraft. The PBS TP100 and TS100 delivers a max. power of 180 kW. Low weight, small installation dimensions, extended intervals between overhauls (TBO), and high efficiency at high altitudes are the competitive advantages of PBS turbine engines. They are able to achieve flight levels of 9,000 m with a maximum starting height of 6,000 m.
