Recent advances in propfan development for commercial aircraft cruising at high transonic speeds are discussed in a series of brief overviews and illustrated with photographs and diagrams. The efficiency and performance advantages and the problem of noise are examined; the history of turboprop design since the 1950s is recalled; NASA, DOT, FAA, and DOD turboprop projects are described; and the results of wind-tunnel and flight tests on particular propeller models are reviewed. Current trends in aircraft reconfiguration and acoustic redesign to reduce cabin noise levels are also surveyed.
