Harrier engine upgrade: Pegasus - flying horsepower

摘要

Supporting the development of a new Pegasus LPC1 fan blade for the US Marine Corps Harrier upgrade led to the revival of a mothballed testbed. When the US Marine Corps asked Rolls-Royce to improve the performance of fan blades for its Pegasus engine for the USMC Harrier (see figure above), it set a test challenge that involved some sophisticated vibration modeling and trials, even including the reactivation of a mothballed test facility.
