Abstract
Abstract Rocket having a nozzle body with a unit of folding fins arranged around the body. Means are provided for swinging the fins out of a normal position into an operating position. A braking device varies the flight path of said rocket and has swiveling flaps which in the normal position of the fins are located between the fins and the nozzle body in an inactive position. When the rocket is launched the forces that come into action swing the flaps into a braking position. Latch members cooperate with the flaps and are displaced by the fins to release the flaps.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
Rocket comprising a nozzle body, folding fins arranged around said body, axles for said fins on said nozzle body parallel to the rocket axis, means for swinging said fins from a folded position alongside said nozzle body into an operating position extended from said body, a braking device on said body to vary the flight path of said rocket comprising swiveling flaps which in said folded position of said fins are located between said fins and said nozzle body in an inactive position and means operative when the rocket is launched swinging said flaps into a braking position extended from said body.
Claim 2
Dependent Claim
102 words
Rocket comprising a nozzle body, folding fins arranged around said body, axles for said fins on said nozzle body parallel to the rocket axis, means for swinging said fins from a folded position alongside said nozzle body into an operating position extended from said body, a braking device on said body to vary the flight path of said rocket comprising swiveling flaps which in said folded position of said fins are located between said fins and said nozzle body in an inactive position and means operative when the rocket is launched swinging said flaps into a braking position extended from said body.
Claim 3
Dependent Claim
33 words
Rocket according to claim 1 wherein latch members are provided for said flaps supported on said axles for said fins and said latch members are displaced by said fins to release said flaps.
Claim 4
Dependent Claim
51 words
Rocket according to claim 2 wherein said fins are brought by a swiveling movement and a displacement in the axial direction out of said folded position into said operating position and said flaps have slots into which said latch members engage upon axial displacement of said fins to release said flaps.
Claim 5
Dependent Claim
51 words
Rocket according to claim 1 wherein axles for said flaps are provided on said nozzle body arranged adjacent the rear ends of said fins in a plane perpendicular to the rocket axis and said flaps in inactive position rest on said nozzle body in front of said axles of said flaps.
Claim 6
Dependent Claim
46 words
Rocket according to claim 4 wherein said flap axles are arranged on said nozzle body adjacent the front ends of said fins in a plane perpendicular to the rocket axis and said flaps in the inactive position lie behind said flap axles on said nozzle body.
Claim 7
Dependent Claim
50 words
Rocket according to claim 1 wherein the braking position of said flaps is in a region bounded by the position in which said flaps are in a plane perpendicular to the rocket axis and by the position in which said flaps are pointing backwards approximately parallel to the rocket axis.
