Abstract
Abstract The system comprises an eight-inch full-bore glide vehicle having retractable aerodynamic lifting surfaces which increase range performance and accuracy. The glide vehicle can be fired to a maximum range of 135 miles without guidance or to a range of 100 miles with accurate terminal guidance. An infrared horizon scanner provides feedback information to small bang-bang servooperated roll-tabs for vehicle despin and roll-attitude stabilization. Target acquisition occurs from the glide path with ship-based radar providing information for mid-course lateral guidance control. A forward observer illuminates the target with laser energy and the vehicle homes in on the target using bangbang monoplane control.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
A gun-launched glide vehicle having a head portion, a rear portion and a center axis comprising the combination of: a gun-launched missile having retractable aerodynamic lifting surfaces mounted thereon; retractable vertical stabilizers mounted on said missile at substantially right angles with respect to said lifting surfaces; roll-tabs located along the trailing edges of said vertical stabilizers; a retractable nose plane mounted adjacent the head portion of said vehicle ahead of said lifting surfaces and said stabilizers; first actuating means for continuously and fixedly deploying said lifting surfaces and vertical stabilizers during flight; second actuating means for deploying said nose plane during flight; servo means to move said roll-tabs and said nose plane; radar means mounted in said missile for receiving directions and generating signals to actuate said roll-tabs in response to said directions; control means for generating signals to actuate said servo means to control said roll-tabs to control missile despin and rollaltitude mounted in said missile; and target acquiring means to locate a target and generate signals to actuate said servo means to move said nose plane to control the pitch of the vehicle.
Claim 2
Dependent Claim
185 words
A gun-launched glide vehicle having a head portion, a rear portion and a center axis comprising the combination of: a gun-launched missile having retractable aerodynamic lifting surfaces mounted thereon; retractable vertical stabilizers mounted on said missile at substantially right angles with respect to said lifting surfaces; roll-tabs located along the trailing edges of said vertical stabilizers; a retractable nose plane mounted adjacent the head portion of said vehicle ahead of said lifting surfaces and said stabilizers; first actuating means for continuously and fixedly deploying said lifting surfaces and vertical stabilizers during flight; second actuating means for deploying said nose plane during flight; servo means to move said roll-tabs and said nose plane; radar means mounted in said missile for receiving directions and generating signals to actuate said roll-tabs in response to said directions; control means for generating signals to actuate said servo means to control said roll-tabs to control missile despin and rollaltitude mounted in said missile; and target acquiring means to locate a target and generate signals to actuate said servo means to move said nose plane to control the pitch of the vehicle.
Claim 3
Dependent Claim
27 words
The glide vehicle of claim 1 wherein said retractable aerodynamic lifting surfaces are wings mounted on pins within said missile and rotate rewardly for storage during launching.
Claim 4
Dependent Claim
19 words
The glide vehicle of claim 2 wherein said first actuating means comprises at least one close-coiled helical compression spring.
Claim 5
Dependent Claim
34 words
The glide vehicle of claim 1 wherein said control means includes a rotating horizon scanner means to measure the roll angle and produce a signal which actuates the servo means to move said roll-tabs.
Claim 6
Dependent Claim
78 words
The glide vehicle of claim 1 wherein said lifting surfaces each have a slot and are mounted in parallel on the glide vehicle and are offset from and parallel to a first line passing through the center axis of the vehicle and said vertical stabilizers are mounted in parallel on the glide vehicle and are offset from and parallel to a second line perpendicular to said first line and passing through the center axis of said glide vehicle.
Claim 7
Dependent Claim
166 words
A glide vehicle for use in a gun as a long range projectile comprising: a vehicle body having a central axis; two lifting surfaces, two vertical stabilizers and two pitch control surfaces mounted on said body in a first retracted position when said projectile is in said gun and in a second deployed position after said projectile clears said gun; roll-tabs mounted on the trailing edges of said vertical stabilizers; first actuating means for continuously biasing said lifting surfaces and vertical stabilizers into said second deployed position; second actuating means for continuously biasing said pitch control surfaces into said second deployed position; servo means to move said roll-tabs and said pitch control surfaces; control means mounted in said projectile for generating signals to actuate said servo means to control said roll tabs to control missile despin and roll-altitude; and target acquiring means to locate a target and generate signals to actuate said servo means to move said nose plane to control the pitch of the vehicle.
Claim 8
Dependent Claim
166 words
A glide vehicle for use in a gun as a long range projectile comprising: a vehicle body having a central axis; two lifting surfaces, two vertical stabilizers and two pitch control surfaces mounted on said body in a first retracted position when said projectile is in said gun and in a second deployed position after said projectile clears said gun; roll-tabs mounted on the trailing edges of said vertical stabilizers; first actuating means for continuously biasing said lifting surfaces and vertical stabilizers into said second deployed position; second actuating means for continuously biasing said pitch control surfaces into said second deployed position; servo means to move said roll-tabs and said pitch control surfaces; control means mounted in said projectile for generating signals to actuate said servo means to control said roll tabs to control missile despin and roll-altitude; and target acquiring means to locate a target and generate signals to actuate said servo means to move said nose plane to control the pitch of the vehicle.
Claim 9
Dependent Claim
67 words
