Research on Development and Application of the Coflow Jet Technology

Abstract

The coflow jet (CFJ) technology, as a new type of integrated flow control technology, has shown potentials in lift enhancement and drag reduction, stall characteristics improvement. The history of the CFJ technology and the research situations at home and abroad is reviewed. The mechanism of CFJ technology’s abilities in lift enhancement and drag reduction is discussed, the theoretical values are also investigated. The research status and typical applications are analyzed. The key issues of this technology in aircraft design, such as aircraft integrated design method, design and analysis technology, component layout strategy and flight control system, are summarized.
