Rolls-Royce is responsible for engine integration, the high-pressure compressor, low-pressure shaft, intermediate casing and the structural parts for the bearing supports.
In addition to the core testing, Pratt & Whitney has performed critical module-level testing for the PurePower engine program, including: fan drive gear system testing with simulations of more than 60,000 takeoffs and landings; hundreds of hours of testing on the low and high-pressure compressor with advanced designs meeting or exceeding efficiency and operability goals.
The engine features a hollow-titanium, swept wide-chord fan; a five-stage low-pressure compressor; a nine-stage high-pressure compressor and a two-stage high-pressure turbine; a low-emissions single annular combustor that will meet future emissions regulations with substantial margin; and a six-stage low-pressure turbine.
The overall project includes several configuration updates: a nickel high-pressure compressor rotor system that provides enhanced corrosion resistance, external changes to accommodate mounting the engine under the wing, an enhanced bleed override system, and higher load-carrying towershaft and gearbox elements to accommodate increased power extraction.
It's very abrasive and the concern is that when encountered in the high-pressure compressor, it will wear the blades and vanes, and you can reduce the length of the blade chord.
P&WC) has released a new group of high-pressure compressor impellers for its popular JT15D-1 and JT15D-4 series engines designed to significantly reduce the cost of a typical engine overhaul.
It also utilizes a high-efficiency, high-pressure compressor to achieve greater torque in the fan mid-shaft than any other jet engine.
In addition to the core testing, Pratt & Whitney has performed critical module-level testing for the PurePower engine program, including: fan drive gear system testing with simulations of more than 40,000 takeoffs and landings; hundreds of hours of testing on the high-pressure compressor with the advanced design meeting or exceeding efficiency and operability goals; nearly 200 hours of testing on the low-pressure compressor verifying low-spool high-speed performance; and extensive fan module testing with 300 pieces of instrumentation that verified performance, operability and acoustics of the low speed fan.
