Twin-rotor Wankel architecture

The RT600-XE utilises a twin-rotor rotary design to deliver higher output with exceptional smoothness and inherent balance. By distributing load across two rotors, the engine produces stronger, more consistent torque while improving thermal efficiency and operational stability. This compact rotary configuration, with far fewer moving parts than comparable reciprocating engines, enables lighter airframe integration, extended range and reduced maintenance without sacrificing power.

Class-leading performance

Designed to maximise power within a compact footprint, the RT600-XE offers an outstanding power-to-weight ratio in its class. Its lightweight rotary architecture frees up valuable mass and space within the airframe, allowing designers to increase payload, extend endurance or improve overall system efficiency. The result is greater performance flexibility without the penalties of size or weight typically associated with high-output engines.

Rotron Rt600-XE - Class-leading power-to-weight performance
Endurance-focused durability & reliability

The RT600-XE is engineered for sustained operation in demanding environments, combining low vibration characteristics with reduced internal wear. This inherently smooth rotary design enhances component longevity and supports long service intervals, with a quoted time between overhauls of up to 1,000 hours. For high-mission-count and endurance-critical applications, it delivers dependable performance, lower lifecycle costs and greater operational confidence.
