The development of the de Havilland Aircraft of Canada (DHC) augmentor-wing powered-lift concept is briefly reviewed from the mid-1960's to the present day.
A parallel DHC research program over the period from the mid-1970's to the present day has developed a very thick high speed compound or multi-foil wing section for the Augmentor-Wing concept. This program proved more successful than initially anticipated and has led to the development of both blown and
More recently, design studies have shown that integration of these technologies leads to very efficient transport aircraft which can achieve Ultra-Stol capability with only the thrust installed for cruise. This has led to a proposal for a high speed operational demonstrator aircraft based upon a C130 Hercules fuselage and empennage powered by a blowing derivative version of the PW2037 engine.
Some other applications for the thick compound section, blown and unblown, are discussed briefly.
