Abstract : The effects of flow rates appropriate to engine requirements through slotted intakes in the rear upper surface of a thick wing were investigated. The basic test configuration incorporated a 31.5 percent thick aerofoil of 3-ft chord and 4-ft span. The aerofoil was equipped with a wide (5 percent chord), full span intake slot, located at 65 percent chord, and operated at values of suction coefficient up to 0.20. Measured results relating to aerofoil force characteristics and intake losses are presented and discussed. (Author)
