The V-22 engines saw a 17 percent power increase during flight tests, according to Defense News, an increase “that will enable the Osprey to fly at 6,000 feet in 95 degree temperatures, an improvement that would address a major challenge to V-22 operations in regions such as the Middle East.”
Tom Hartmann, Rolls’ senior vice president for customer business, said the biggest driver of the power improvement comes from a relatively new turbine added to the engine.
The Block 3 turbine design, based on a commercial product Rolls-Royce has used on other aircraft, began being installed on new production models in July 2012.
Also playing a role in the extra power is improvements to flow capacity of the fuel valve and a software update.
“You don’t need the extra power all the time, so when you don’t need it you’re running cooler, and when you run cooler it lowers operational cost,” Hartmann told Defense News. “We will give operators what they need when they need to run certain missions, but for the vast number of missions it will have a positive effect on durability.”
