The TJ-120 is a compact, simple-structure turbojet delivering at least 115 daN of thrust with fuel consumption of ≤1.25 kg/(daN·h). It offers excellent high-altitude performance up to 12,000 m and rapid starting from 0–5,000 m elevation. A generator module can be integrated on request.
The TJ-120 is a compact and simple-structure turbojet engine featuring low fuel consumption and reliable operation, designed for aircraft propulsion applications. It offers excellent high-altitude and high-speed adaptability, rapid start capability, and outstanding overload resistance. A generator module can be integrated according to application requirements. The engine is capable of operating under a wide range of temperature and starting-altitude conditions, uses dedicated jet fuel without the need for lubricating oil, and features optimized dimensions and weight. With a qualified service life of at least 20 hours, it is suitable for demanding flight operating environments. Maximum thrust is at least 115 daN at sea-level standard atmosphere, with maximum operating altitude of at least 12,000 m, bleed air flow of at least 0.12 g/s, and a diameter of no more than 238 mm at a weight of no more than 15 kg.
Key specifications: Maximum Thrust: ≥ 115 daN (sea level standard atmosphere); Specific Fuel Consumption: ≤ 1.25 kg/(daN·h); Maximum Operating Altitude: ≥ 12,000 m; Weight: ≤ 15 kg; Diameter: ≤ 238 mm; Service Life: ≥ 20 h.
