Abstract : The history of wave rotor applications to aircraft turbine engines is reviewed in order to determine the reasons for past successes and failures. The results show that two different kinds of wave rotors performed successfully in laboratory tests in the mid-1950s and late 1960s. These were the Pearson wave rotor/turbine built and tested by Ruston Hornsby in England and the Complex pressure exchange wave rotor built by the Brown-Boveri Company and tested by the Rolls-Royce Company. With the advent of advanced gasdynamic numerical simulation techniques embodied in an experimentally verified computer flow code for wave rotors, the prospect of upgrading these earlier wave rotor designs for a modern high temperature, high pressure aircraft turbofan engine looks very attractive. The flow code would allow very rapid design optimization and cut down the time and costs for successful engine development. A suitable niche for the initial application of wave rotor turbofans has appeared in the area of small, low-TSFC engines; wave rotors may also allow better cruise conditions for high performance engines.
