A circulation control wing (CCW) is a form of high-lift device for use on the main wing of an aircraft to increase the maximum lift coefficient and reduce the stalling speed. CCW technology has been in the research and development phase for over sixty years. Blown flaps were an early example of CCW.[1]
The CCW works by increasing the velocity of the airflow over the leading edge and trailing edge of a specially designed aircraft wing using a series of blowing slots that eject jets of high-pressure air. The wing has a rounded trailing edge to tangentially eject the air through the Coandă effect thus causing lift.[2] The increase in velocity of the airflow over the wing also adds to the lift force through conventional airfoil lift production.[3]
