Abstract
Abstract Aircraft jet engine having a vectoring discharge for pitch and yaw control purposes including means for maintaining such control during low thrust or reversing jet operation. A vectoring nozzle is arranged on the exit of the jet tube in the manner of a ball joint for universal swiveling and the lateral and vertical control obtained thereby. Openings are provided for both the inner and outer portion of the cooperating spherical members such that when the vectoring nozzle swivels on the jet pipe more or less of the openings on the respective sides thereof come into register with each other. By directing the discharge from said openings in a reversing direction, same will function as reversing jets when the nozzle is closed and by swiveling thereof such discharge can be directed to one side or the other of the aircraft to obtain the desired directional control.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
222 words
A nozzle apparatus mounted on one end of a jet pipe of an aircraft jet engine, comprising: a hollow, partially spherical first member mounted on said one end of said jet pipe and having an inlet at one end communicating with said one end of said jet pipe and a first outlet at the other end; means defining a plurality of first openings in said first member upstream of said first outlet; a hollow, partially spherical second member mounted in telescoping relation to said first member, said second member including means defining a second outlet at one end communicating with said first outlet, one of said first and second members being adapted for movement relative to the other of said first and second members; and means defining a plurality of second openings in said second member upstream of said second outlet, each of said plurality of said second openings communicating with a respective one of said plurality of said first openings, a relative movement between said first and second members causing one of said plurality of first and second openings to move relative to the other of said plurality of first and second openings to thereby regulate the effective cross-sectional area of said first and second openings to thereby control the amount of exhaust gases passing through said first and second openings.
Claim 2
Dependent Claim
222 words
A nozzle apparatus mounted on one end of a jet pipe of an aircraft jet engine, comprising: a hollow, partially spherical first member mounted on said one end of said jet pipe and having an inlet at one end communicating with said one end of said jet pipe and a first outlet at the other end; means defining a plurality of first openings in said first member upstream of said first outlet; a hollow, partially spherical second member mounted in telescoping relation to said first member, said second member including means defining a second outlet at one end communicating with said first outlet, one of said first and second members being adapted for movement relative to the other of said first and second members; and means defining a plurality of second openings in said second member upstream of said second outlet, each of said plurality of said second openings communicating with a respective one of said plurality of said first openings, a relative movement between said first and second members causing one of said plurality of first and second openings to move relative to the other of said plurality of first and second openings to thereby regulate the effective cross-sectional area of said first and second openings to thereby control the amount of exhaust gases passing through said first and second openings.
Claim 3
Dependent Claim
28 words
A nozzle apparatus according to claim 1, wherein said first and second openings are aligned with a plane formed by the yaw and pitch axes of said aircraft.
Claim 4
Dependent Claim
19 words
A nozzle apparatus according to claim 1, wherein said first and second openings are each provided with guide vanes.
Claim 5
Dependent Claim
20 words
A nozzle apparatus according to claim 1, wherein said first and second openings are each provided with adjustable guide vanes.
Claim 6
Dependent Claim
51 words
A nozzle apparatus according to claim 1, wherein said means defining said second outlet includes means for closing said second outlet whereby when said second outlet is closed a relative movement between said first and second members effectively controls said amount of exhaust gases passing through said first and second openings.
Claim 7
Dependent Claim
43 words
A nozzle apparatus according to claim 5, wherein said means for closing said second outlet comprises movable clamshell door Means for varying the cross-sectional area of said second outlet between a fully opened position and a fully closed position and any intermediate position.
