Abstract
Abstract Control unit for the lift engines of vertical or short takeoff aircraft for correction of motion preferably in relation to the roll axis. The lift engine discharges into a branched conduit of which each respective branch discharges to opposite external sides of the aircraft fuselage Infinitely adjustable means are provided for selecting and proportioning as desired the respective amounts of the engine discharge introduced into and conducted through said respective branches.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
167 words
In vertical or short takeoff aircraft having a lift engine for distribution of the exhaust gas into a branched exhaust gas outlet tube, a control unit for the correction of motion in relation to the attitude of the aircraft axes, the improvement comprising: means for mounting said lift engine in said aircraft fuselage, the axis of said lift engine being at a transverse angle to the longitudinal axis of said aircraft; adjustable distributing means for adjustably distributing a selected amount of said exhaust gas into selected ones of said branches of said exhaust gas outlet tube, said adjustable distributing means including a control flap in said outlet and first pivot means for pivotally supporting said control flap about an axis which is at a right angle with the longitudinal axis of said lift Engine, a pair of gas guide plates and second pivot means for pivotally securing each of said gas guide plates to said control flap at the end thereof remote from said first pivot means.
Claim 2
Dependent Claim
167 words
In vertical or short takeoff aircraft having a lift engine for distribution of the exhaust gas into a branched exhaust gas outlet tube, a control unit for the correction of motion in relation to the attitude of the aircraft axes, the improvement comprising: means for mounting said lift engine in said aircraft fuselage, the axis of said lift engine being at a transverse angle to the longitudinal axis of said aircraft; adjustable distributing means for adjustably distributing a selected amount of said exhaust gas into selected ones of said branches of said exhaust gas outlet tube, said adjustable distributing means including a control flap in said outlet and first pivot means for pivotally supporting said control flap about an axis which is at a right angle with the longitudinal axis of said lift Engine, a pair of gas guide plates and second pivot means for pivotally securing each of said gas guide plates to said control flap at the end thereof remote from said first pivot means.
Claim 3
Dependent Claim
167 words
In vertical or short takeoff aircraft having a lift engine for distribution of the exhaust gas into a branched exhaust gas outlet tube, a control unit for the correction of motion in relation to the attitude of the aircraft axes, the improvement comprising: means for mounting said lift engine in said aircraft fuselage, the axis of said lift engine being at a transverse angle to the longitudinal axis of said aircraft; adjustable distributing means for adjustably distributing a selected amount of said exhaust gas into selected ones of said branches of said exhaust gas outlet tube, said adjustable distributing means including a control flap in said outlet and first pivot means for pivotally supporting said control flap about an axis which is at a right angle with the longitudinal axis of said lift Engine, a pair of gas guide plates and second pivot means for pivotally securing each of said gas guide plates to said control flap at the end thereof remote from said first pivot means.
Claim 4
Dependent Claim
167 words
In vertical or short takeoff aircraft having a lift engine for distribution of the exhaust gas into a branched exhaust gas outlet tube, a control unit for the correction of motion in relation to the attitude of the aircraft axes, the improvement comprising: means for mounting said lift engine in said aircraft fuselage, the axis of said lift engine being at a transverse angle to the longitudinal axis of said aircraft; adjustable distributing means for adjustably distributing a selected amount of said exhaust gas into selected ones of said branches of said exhaust gas outlet tube, said adjustable distributing means including a control flap in said outlet and first pivot means for pivotally supporting said control flap about an axis which is at a right angle with the longitudinal axis of said lift Engine, a pair of gas guide plates and second pivot means for pivotally securing each of said gas guide plates to said control flap at the end thereof remote from said first pivot means.
Claim 5
Dependent Claim
35 words
A control unit according to claim 1, wherein the control flap has on both sides gas guide plates which are adapted to be automatically pivoted about an axis arranged at the tip of the flap.
