HJZ75 Turboshaft Engine: Lightweight, Efficient, and Powerful

The HJZ75 is an advanced small turboshaft engine, specifically designed for aviation applications demanding exceptional power-to-weight ratio and compact dimensions. Integrating high performance, high reliability, and broad environmental adaptability, it is the ideal power choice for unmanned helicopters and light rotorcraft.

Core Advantages:

Robust Power, Lightweight Design:With a dry weight of only 25 kg, it delivers a maximum power output of 75 kW, providing an unparalleled power density (approx. 3 kW/kg). This significantly enhances aircraft payload capacity and maneuverability.

Ultra-High Speed Operation:Capable of reaching a maximum speed of 65,000 rpm, ensuring rapid response and highly efficient, smooth power delivery.

Excellent Fuel Efficiency:Features a low specific fuel consumption (SFC) of only 0.45 kg/(kW·h), optimizing range and operational economy while providing ample power.

Exceptional Environmental Tolerance:Possesses outstanding environmental resilience, capable of stable operation in extreme ambient temperatures ranging from -40°C to +45°C and supporting flight missions up to 8,000 meters (26,247 ft) in altitude.

Extreme Compactness:Boasts a refined external design with a maximum length of 870 mm and a maximum diameter of 208 mm. This greatly saves installation space, offering high flexibility for overall aircraft layout.

High-Reliability Design:A maximum exhaust gas temperature (EGT) design limit of 450°C demonstrates the reliability and durability of its core components under high-temperature conditions.

Application Areas:

Medium-to-Large Unmanned Helicopters

Light Manned/Unmanned Rotorcraft

Vertical Takeoff and Landing (VTOL) Aircraft

Other fields requiring high power density propulsion systems.
