By Air Commodore F Whittle

The main argument against the gas turbine was that the maximum temperatures permissible with materials available, or likely to be available, was such that the ratio of positive to negative work in the constant pressure cycle could not be great enough to allow of a reasonable margin of useful work to be obtained, after allowing for the losses in the turbine and compressor.

There seemed to be a curious tendency to take it for granted that the low efficiencies of turbines and compressors commonly cited was inevitable. I did not share that pessimism, because I was convinced that big improvements in these efficiencies were possible.
