RT700-XE
The RT700-XE is an ultra-high-performance twin-rotor rotary engine delivering exceptional power density in a compact package. Liquid-cooled and fuel-injected, it serves demanding aerospace and high-endurance UAV platforms.
With peak output up to 220 hp and continuous mission capability, the RT700-XE delivers streamlined integration via a closed-loop cooling system, minimal vibration and high-efficiency delivery for next-generation propulsion platforms.
The RT700-XE’s innovative twin-rotor Wankel architecture minimises reciprocating mass while maximising torque. Its liquid-cooling, programmable fuel injection and linear power-curve deliver class-leading power-to-weight and operational longevity - designed for endurance, agility and high performance in compact systems.
High Power Density: Twin-rotor rotary design achieves outstanding power-to-weight performance and rapid transient response with compact packaging.
Advanced Thermal Management: Liquid-cooling system and optimised rotor materials ensure stable temperatures, reduced wear and sustained high-load performance.
Seamless Integration: Modular architecture and minimal vibration deliver easy installation and compatibility across varied air-frames, UAV and VTOL platforms.
Fan-drive system range.
Ultra-High Performance Twin-Rotor Engine for Advanced UAV & Aerospace Platforms
The RT700-XE employs a twin-rotor rotary configuration to deliver exceptional power and balance in a compact package. Two rotors working in harmony provide a broad torque band and smooth, linear power delivery. This high-output performance suits demanding applications, while the simplicity of the rotary design enables lighter integration and improved reliability over comparable piston engines.
With a peak output of 220 hp from just 690 cc, the RT700-XE sets a new benchmark for power density among normally aspirated engines. Its lightweight, compact design frees mass and space within the airframe, allowing higher payloads or improved aerodynamics. This class-leading power-to-weight ratio enables faster acceleration and sustained high speeds without the bulk of heavier propulsion systems.
The RT700-XE pairs liquid cooling and programmable fuel injection with a CANbus interface for precise, efficient operation and easy integration with advanced control systems. Its optimised thermal management and fuel delivery sustain peak performance and efficiency across diverse conditions. Combined with its low-vibration rotary design, this ensures smoother operation, reduced wear, and long-term durability, making it ideal for demanding platforms where reliability and economy matter.
