RT600-HC
The RT600-HC twin-rotor rotary engine is engineered for VTOL and rotorcraft missions. With optimised power-to-weight, liquid-cooling and compact form-factor, it offers high performance and endurance for advanced multi-role platforms.
The RT600-HC sets a new standard in VTOL propulsion, combining a compact twin-rotor design with exceptional power, efficiency, and reliability. Lightweight and versatile, it delivers high-performance operation and enduring durability for the most demanding rotary-wing applications.
The RT600-HC’s twin-rotor Wankel architecture minimises reciprocating mass, reducing vibration and simplifying integration. Combined with liquid-cooling, fuel-injection and high-performance materials, it delivers excellent power-density, durability and long service-intervals tailored for high-demand rotorcraft and endurance missions.
Optimised Power-Density: Twin-rotor architecture achieves high power relative to weight, enabling agile airframes and increased payload capability.
Efficient Thermal Management: Liquid-cooling system combined with advanced rotor materials ensures stable temperatures and long-life operation under high load.
Integration-Ready Design: Compact layout and flexible mounting allow simplified installation into VTOL, helicopter-type and unmanned systems with minimal ancillary mass.
Fan-drive system range.
High-Density Twin-Rotor Propulsion Engine for VTOL and Rotorcraft UAV Platforms
The RT600-HC employs a twin-rotor rotary design to deliver high output with exceptional smoothness and inherent balance. By splitting the load across two rotors, the engine generates stronger, more consistent torque while enhancing thermal efficiency and operational stability. This compact rotary layout, with significantly fewer moving parts than comparable engines, allows lighter airframe integration, extended range, and reduced maintenance, all without compromising power.
Designed to maximise power within a compact footprint, the RT600-HC delivers an exceptional power-to-weight ratio for VTOL and rotorcraft UAVs. Its lightweight twin-rotor rotary architecture frees valuable mass and space within the airframe, enabling increased payload, extended endurance, or enhanced system efficiency. The result is greater operational flexibility and performance without the size or weight penalties typically associated with high-output engines.
The RT600-HC is engineered for sustained operation in demanding VTOL and rotorcraft UAV environments, combining low vibration with minimal internal wear. Its inherently smooth twin-rotor design enhances component longevity and supports extended service intervals, with a quoted time between overhauls of up to 1,000 hours. For high-mission-count and endurance-critical operations, it delivers dependable performance, reduced lifecycle costs, and greater operational confidence.
