The TJ150 engine has a dry weight of 19.6 kg and measures 520 mm long with an outer diameter of 272 mm. The company claims that the engine offers 1.5 kN of thrust for a potential maximum speed of Mach 0.9, depending on the aerodynamic and weight characteristics of its host platform. In contrast, the TJ100 engine has a thrust rating of 1.3 kN.
The TJ150 engine is powered by JET A-1 fuel and equipped with an integrated starter generator that improves its starting reliability. It can generate an electrical power output of 600W at 28 V.
Additional engine features include an integrated electronic control system and full authority digital engine control (FADEC). It has a stated maximum operating altitude of 32,808 ft (10,000 m).
Company specifications indicate that the engine can operate in austere climates and in temperatures from -50 ˚C to 45 ˚C.
Engine trials were conducted during 2017–18 and final serial production documentation was completed in August 2018.
The company is looking to secure customers for the new engine in Asia and Europe. Its TJ100 engine was successfully installed in the SubSonex single-seat microjet and the Diana target drone.
