Abstract
Abstract An apparatus for correcting the flight path of a missile, such as a high speed shell or projectile, includes a missile body with a distributor for flow means rotatable in the missile body. An outlet opening for the flow means from the distributor is positionable relative to a blow-out opening on the outer circumference of the missile body for effecting a correcting thrust and for switching rapidly between different transverse forces, a missile tip provided with the blow-out openings is arranged to communicate with the outlet openings from the distributor. The extent to which the blow-out openings and the outlet openings align or overlap can be adjusted by a drive for the distributor acting in cooperation with the braking arrangement.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
An apparatus for correcting the flight path of a missile, such as a high speed projectile, comprising a missile body having a central axis and an outer circumferential surface, a flow means distributor rotatably mounted in said missile body and having at least one outlet opening for the flow means distributor for effecting a transverse force on said missile body, at least one blow-out opening in the circumferential surface of said missile body alignable with said outlet opening, and a braking means acting between said distributor and said missile body, wherein the improvement comprises that said missile body includes a missile part rotatable independently of said distributor and said missile part being stable with respect to load, means for rotating said distributor, and said at least one said outlet opening and said at least one blow-out opening being at least partially alignable in a controlled manner by said means for rotating said distributor and by said braking means.
Claim 2
Independent Claim
158 words
An apparatus for correcting the flight path of a missile, such as a high speed projectile, comprising a missile body having a central axis and an outer circumferential surface, a flow means distributor rotatably mounted in said missile body and having at least one outlet opening for the flow means distributor for effecting a transverse force on said missile body, at least one blow-out opening in the circumferential surface of said missile body alignable with said outlet opening, and a braking means acting between said distributor and said missile body, wherein the improvement comprises that said missile body includes a missile part rotatable independently of said distributor and said missile part being stable with respect to load, means for rotating said distributor, and said at least one said outlet opening and said at least one blow-out opening being at least partially alignable in a controlled manner by said means for rotating said distributor and by said braking means.
Claim 3
Dependent Claim
46 words
An apparatus, as set forth in claim 1, wherein said means for rotating said distributor enables a rotation in the same direction with said rotating part of said missile body at a speed which is greater than the rotational speed of the independently rotatable missile part.
Claim 4
Dependent Claim
65 words
An apparatus, as set forth in claim 1 or 2, wherein said means for rotating said distributor comprises a spring drive, said rotatable missile part comprises a missile tip on said missile body, said spring drive is clamped between said missile tip and said distributor and said spring drive is tensioned during the application of said braking arrangement between said distributor and said missile body.
Claim 5
Dependent Claim
16 words
An apparatus, as set forth in claim 3, wherein said spring drive is a coil spring.
Claim 6
Dependent Claim
55 words
An apparatus, as set forth in claim 3, wherein the clamping of said spring drive is provided on said missile tip by a stop and on said spring drive by a spring stop arranged to contact said stop on said missile tip, and said spring stop can override said stop at a predetermined spring tension.
Claim 7
Dependent Claim
73 words
An apparatus, as set forth in claim 1, wherein said means for rotating said distributor comprises a friction drive which comprises a first part on said missile tip and a second part on said distributor and said friction drive is arranged so that when said braking arrangement is not applied said distributor is carried along by said rotating missile tip and when the braking arrangement is applied said distributor is braked or stopped.
Claim 8
Dependent Claim
37 words
An apparatus, as set forth in claim 1, wherein said means for rotating said distributor comprises a gas generator in said missile body and said outlet opening from said distributor being off-center with respect the central axis.
Claim 9
Dependent Claim
95 words
An apparatus, as set forth in claim 1, wherein said distributor has two outlet openings, said missile part comprises a missile tip having two blow-out openings arranged at least to partially overlap with the outlet openings, during identical overlapping of said outlet openings and said blow-out openings the resulting transverse forces add up to zero and in a change of the overlapping extent between said outlet openings and said blow-out openings when the angular position between said distributor and said missile tip is effected a transverse force is established for acting on said missile body.
Claim 10
Dependent Claim
45 words
An apparatus, as set forth in claim 1, wherein said missile part is a missile tip, stops are provided between said distributor and said missile tip for holding said distributor in a determined angular position relative to said missile tip corresponding to a zero command.
Claim 11
Dependent Claim
32 words
Apparatus, as set forth in claim 9, wherein said stops on said missile tip are constructed as spring stops for overriding said stops on said distributor during rotation of said missile tip.
Claim 12
Dependent Claim
29 words
An apparatus, as set forth in claim 9, wherein said stop on said distributor is a spring stop arranged to override a fixed said stop on said missile tip.
Claim 13
Dependent Claim
42 words
An apparatus, as set forth in claim 11, wherein said spring has a bent end forming said spring stop and is arranged to contact said stop on said missile tip and said spring is connected at its opposite end with said distributor.
Claim 14
Dependent Claim
78 words
An apparatus, as set forth in claim 1, wherein said missile part is a missile tip, said missile tip having a bore extending therethrough along the central axis thereof for directing ram air into said missile body, and for producing a transverse force on said missile body said bore in said missile tip communicates with a centrally arranged gas duct in said distributor, and said gas duct in said distributor leads to said outlet openings from said distributor.
Claim 15
Dependent Claim
45 words
An apparatus, as set forth in claim 4, wherein the relative angular position between said missile tip and said distributor is defined by said coil spring and bears against said distributor in a tensioned position and bears against said missile tip in an expanded position.
Claim 16
Dependent Claim
36 words
An apparatus, as set forth in claim 1, wherein said missile part comprises a missile tip, angle transmitters are located between said missile tip and said missile body and between said distributor and said missile body.
