The Rolls-Royce RR500TS engine is being explored for potential use in Bell 206B JetRanger helicopters. According to the company, the RR500TS offers more power at takeoff and in hot and high conditions than existing engines in its class.

Rolls-Royce and Bell Helicopter signed a memorandum of understanding (MOU) to explore options for the retrofit of Bell 206B JetRanger helicopters with the RR500TS (turboshaft) engine. The MOU will allow the joint evaluation of third-party suppliers to develop RR500TS Supplemental Type Certificate retrofit kits replacing the M250 engines that currently power the JetRanger—a five-seat, light turbine helicopter used in corporate, utility, law enforcement, and homeland security missions. FAA type certification for the RR500 turboshaft is expected in late 2011, with production engines to follow.

Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
