Abstract:
1. An aircraft comprising: a channel wing having a blown channel circulation control wing (CCW), the blown channel CCW having a channel that has a substantially rounded trailing edge, the channel further having a trailing-edge slot that is adjacent to the substantially rounded trailing edge of the channel, the trailing-edge slot having an inlet connected to a source of pressurized air and the trailing-edge slot being capable of tangentially discharging pressurized air at a blowing rate over the substantially rounded trailing edge; and a propeller being located in the channel and being ahead of the substantially rounded trailing edge and aft of a leading edge of the blown channel CCW, the propeller providing a propeller thrust and increased inflow velocity in a near-circular flow stream across the channel wing, wherein the propeller thrust in the near-circular flow stream across the channel wing is deflected by the pressurized air being discharged over the substantially rounded trailing edge, which provides a high lift that is obtained independent of an aircraft angle of attack, thus preventing the asymmetry, separated flow, and stall typically experienced by an unblown channel wing at the high angle of attack it required for high lift generation.
