Rolls-Royce hits key milestone with first development test of new RR500 engine

Rolls-Royce, the global power systems company, has completed the first development test runs of the new RR500 engine. The initial runs included engine start and accelerations to part power. The test team is proud that the engine successfully met all the relevant and applicable milestones.

In upcoming weeks, the RR500 engine will continue test runs at increased power levels. As part of the thorough testing program, performance data will be obtained and the engine inspected.

Chris Fultz, Rolls-Royce Program Director - RR500, recognized the project team's dedicated work. "First engine to test is a significant milestone for engine development programs and requires coordinated effort from individuals across the company. The entire team worked to ensure this milestone was achieved on time and that the engine would meet design and performance requirements. This test completion is a major success for the program."

The RR500 engine is being designed and developed in both turboprop and turboshaft configurations and is a higher power derivative of the RR300 engine now powering the Robinson R66. The RR500 will have a take-off power rating of 450 - 475 SHP, depending on the application. The engine will provide a significant increase in hot and high power over existing products in this power class, while also providing lower acquisition and direct operating costs.

Rolls-Royce is working closely with several aircraft manufacturers during engine development to deliver what the market requires. The turboshaft model will be certified with a hydro-mechanical control system, while the turboprop model will feature a new FADEC system based on that in development for the M250-C30R/3 engine powering the OH58D Kiowa Warrior aircraft.
