The possibility of using turbine-type compressors across the entire range of inlet pressures from high vacuum to atmosphere was recognized from the very beginning when the axial-flow compressor
was evaluated as a high-vacuum pump and the potential usefulness of centrifugal and peripheral-flow regenerative blowers was considered.
They accomplished this by designing a high-efficiency axial-flow compressor and six can-type combustors, and by providing the new turbine with a high inlet temperature.
The engineers based the M7A-01's 12-stage axial-flow compressor design on Kawasaki's experience designing and manufacturing compressors for blast furnace blowers.
Paul Bladon, before his sad death in 2008, pioneered the machining of minute axial-flow compressor blade discs--blisks-from solid material using electrodischarge machines (EDMs).
A multi-stage axial-flow compressor is followed by a single-stage radial compressor feeding air into the reverse-flow combustion chamber.
Paul Barrett, co-founder and chairman of Bladon Jets, says: "Successful miniaturisation of the axial-flow compressor
has been the key to what we are doing.
