PBS Unveils New UAV Turbine Engines
PBS Velka Bites is launching two new UAV Turbine Engines. With its in-house expertise in design, development, production and testing, the PBS continually works on a new engine development in order to meet missile and UAV market requirements. This year, the company is finalizing the development of new turbojet engines PBS TJ150 and PBS TJ80.
Weighing 19.6 kg and with a diameter of 272 mm, the PBS TJ150 engine 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 a speed of up to 0.9 M, ambient temperature of -50 °C to +45 °C and altitudes of up to 9,000 m. It has an ability of ground and in-flight restart of up to 4,000 m with maximum speed of 0.6 M.
The newly developed engine PBS TJ150 is based on the most commercially successful model PBS TJ100 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. Almost 800 units have been delivered to customers globally.
Another new product form PBS is the TJ80 Turbojet Engine. The main features of TJ80 are compact design, electric starting system, excellent thrust-to-weight ratio, low fuel consumption, control system (FADEC), possibility of ground and in-flight restart etc. It delivers a maximum thrust of 900 N and has a maximum engine speed of 58000 RPM. Up to a range of 10000 m, TJ80 has a maximum speed of 0.9 M.
PBS turbojet engines have proven to be efficient propulsion units in hundreds of aerial targets, UAV and UCAV systems and piloted micro jets, mainly in France, Germany, China, Russia, Spain, UAE, USA, and other countries. PBS jet engines are known for their excellent power-to-weight ratio, compact design, reliable operation, low fuel and oil consumption together with starting at high altitudes and at high speeds.
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 develop 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.
Auxiliary Power Units (APU) which are used all around the world, both in defence and civil airplanes and helicopters is also one of the main product lines of PBS. They operate as air generators for starting systems and as emergency power and hydraulic sources. Their main advantages are simultaneous supply of electric power and compressed air, continuous operation for up to 6 hours, long service life and ability to start and operate in altitudes of up to 6,000 m.
PBS holds important EASA certificates for aerospace products according to Part 21, Section A, Subpart J, G including Design Organisation Approval (DOA), Production Organization Approval (POA) and Maintenance Organization Approval (MOA).
