An aircraft comprising a Channel Wing having blown channel circulation
control wings (CCW) for various functions. The blown channel CCW includes
a channel that has a rounded or near-round trailing edge. The channel
further has a trailing-edge slot that is adjacent to the rounded trailing
edge of the channel. The trailing-edge slot has an inlet connected to a
source of pressurized air and is capable of tangentially discharging
pressurized air over the rounded trailing edge. The aircraft further has
a propeller that is located in the channel and ahead of the rounded
trailing edge of the channel. The propeller provides a propeller thrust
exhaust stream across the channel wing to propel the aircraft through the
air and to provide high lift. The pressurized air being discharged over
the rounded trailing edge provides a high lift that is obtained
independent of an aircraft angle of attack, thus preventing the
asymmetry, separated flow, and stall experienced by the CC wing at the
high angle of attack it required for high lift generation. The aircraft
can further include blown outboard circulation control wings (CCW) that
are synergistically connected to the blown channel CCWs. The blown
outboard CCWs provide additional high lift, control thrust/drag
interchange, and can provide all three aerodynamic moments when
differential blowing is applied front-to-rear or left-to-right. Both the
blown channel CCW and the outboard CCW also have leading-edge blowing
slots to prevent flow separation or to provide aerodynamic moments for
control.
