Wing mounted thrust reverser

Claim 2

A wing mounted thrust reverser for an airplane having a thrust augmentation system comprising: a. a flap having upper and lower segments which in extended position for take-off or landing provide a channel therebetween, b. means for rearwardly directing into the channel a spanwise volume of gas under pressure from plenum chambers through wing mounted nozzles, c. means for turning the rearwardly directed gas for smooth flow within the channel between the flap segments, and d. means for moving the turning means into the channel to redirect the gas flow forward to spoil the wing lift characteristics and provide a reversing thrust.

Claim 3

A wing mounted thrust reverser for an airplane comprising: a. a rearwardly directed stream of high pressure gas from plenum chambers extending spanwise along the wing rear span thence through a plurality of nozzles distributed along flap areas, b. a series of segmented flaps of the high lift thrust augmentation type, c. a member which has a Coanda surface along each flap adjacent the nozzle outlets to turn the gas stream for smooth flow between the segments of the flaps, d. a linkage system between the member and the wing, and e. means for imparting motion to the linkage to move the back surface of the member between the segments and into the stream of gas to direct said stream forward to impart a reversing thrust to the airplane.

Claim 4

A wing mounted thrust reverser for an airplane comprising: a. a rearwardly directed stream of high pressure gas from plenum chambers extending spanwise along the wing rear span thence through a plurality of nozzles distributed along flap areas, b. a series of segmented flaps of the high lift thrust augmentation type, c. a member which has a Coanda surface along each flap adjacent the nozzle outlets to turn the gas stream for smooth flow between the segments of the flaps, d. a linkage system between the member and the wing, and e. means for imparting motion to the linkage to move the back surface of the member between the segments and into the stream of gas to direct said stream forward to impart a reversing thrust to the airplane.

Claim 5

A wing mounted thrust reverser for an airplane as in claim 2 wherein the member has a turning vane connected to the back surface.

Claim 6

A combination of an airplane with wings, bypass turbofan engines, and a wing mounted thrust reverser comprising: segmented thrust augmentation flaps, a ducting system extending from the engines to rearwardly direct a stream of gas spanwise between the segments of the flaps, a member having a Coanda surface located between the gas outlet and the flaps to turn the stream of gas smoothly between the flap segments, a double bar linkage each of which is pivotally mounted between the member and the wing wherein the links effect an acute angle to each other, and means for imparting motion to the linkage to raise and rotate the member into the stream of gas with a curved back side to the Coanda surface facing toward and redirecting the stream of gas forward.

Claim 7

A combination of an airplane with wings, bypass turbofan engines, and a wing mounted thrust reverser comprising: segmented thrust augmentation flaps, a ducting system extending from the engines to rearwardly direct a stream of gas spanwise between the segments of the flaps, a member having a Coanda surface located between the gas outlet and the flaps to turn the stream of gas smoothly between the flap segments, a double bar linkage each of which is pivotally mounted between the member and the wing wherein the links effect an acute angle to each other, and means for imparting motion to the linkage to raise and rotate the member into the stream of gas with a curved back side to the Coanda surface facing toward and redirecting the stream of gas forward.

Claim 8

A wing mounted thrust reverser for an airplane having a thrust augmentation system comprising: a pair of plenum chambers located on each wing and extending spanwise between wing rear span and wing flaps; a thrust augmentation flap segmented into an upper and a lower part extending spanwise along the wing to form a channel therebetween; nozzles extending from each plenum chamber direct a stream of gas rearward into the channel; a member which has a Coanda surface extends adjacent the nozzles and toward the flaps to turn the gas stream for smooth flow into the channel, said member has a curved back side; a double bar linkage extends from the wing to the member; and means for actuating the linkage to raise and rotate the member to place the curved back side of the member in the channel directly into the stream of gas to reverse the thrust.

Claim 9

A wing mounted thrust reverser for an airplane having a thrust augmentation system comprising: a pair of plenum chambers located on each wing and extending spanwise between wing rear span and wing flaps; a thrust augmentation flap segmented into an upper and a lower part extending spanwise along the wing to form a channel therebetween; nozzles extending from each plenum chamber direct a stream of gas rearward into the channel; a member which has a Coanda surface extends adjacent the nozzles and toward the flaps to turn the gas stream for smooth flow into the channel, said member has a curved back side; a double bar linkage extends from the wing to the member; and means for actuating the linkage to raise and rotate the member to place the curved back side of the member in the channel directly into the stream of gas to reverse the thrust.

Claim 10

A wing mounted thrust reverser as in claim 5 further comprising: a turning vane connected to the back side of the member.

Claim 13

A method of effecting a wing mounted thrust reverser as in claim 7 with the further step of utilizing a turning vane on the back side of the member to increase the efficiency of the reversing thrush.
