-Reaction Engines has successfully demonstrated the integration of its innovative precooler technology with existing jet-engine architecture, achieving sustained Mach 3.5 operating conditions and demonstrating the viability of a key element for its innovative propulsion system concept for high-Mach/hypersonic aircraft.
In the current ground-based testing programme, Reaction Engines’ innovative precooler has been integrated and close-coupled with a modified Rolls-Royce jet engine to simulate a propulsion system for an unpiloted, reusable high-Mach air vehicle concept.
The test programme initially achieved sustained Mach 2.3 operating conditions, representing speeds faster than Concorde’s maximum operating speed, before operating at Mach 3.5 pressures and temperatures, matching the maximum known airspeed record of the SR-71, the world’s fastest aircraft powered by an air-breathing engine.
In addition to developing precooler technology, Reaction Engines is developing and testing novel high-Mach intake designs and technology for hypersonics capabilities. Hardware is currently being manufactured and assembled for a full-scale ground-based high-Mach thermomechanical test. Sub-scale aerodynamic wind-tunnel testing is already being undertaken to assess intake performance over a range of supersonic conditions.
Mark Thomas, Chief Executive of Reaction Engines, said: “As the world’s most advanced heat exchanger technology company, this significant milestone is a testament to our relentless efforts to develop novel, innovative, reusable and affordable propulsion systems for hypersonic air vehicles at pace. This capability is transferrable to thermal management solutions for multiple applications and mission profiles.”
