Abstract

Abstract An improvement for an aerodynamic missile, such as a torpedo, wherein the missile has a main parachute which is contained by a container at the aft end thereof, the improvement including an initial stabilizing and velocity retarding parachute releasably folded about the container; and means releasably retaining the stabilizing parachute to the container. The container may be constructed of a flexible material such as cloth, and an improved means may be provided for releasing the main parachute from this container.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 101 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, a means for releasing the main parachute from the container comprising: a ring connected to the aft end of the missile and having a radially extending annular ledge; said container being folded over the transverse ledge; lacing extending through the folded over portion of the container for drawing the container into a tight unreleased condition about the ring; and means carried by the ring for releasing the lacing so as to in turn deploy the main parachute from the container.
Claim 2
Dependent Claim 101 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, a means for releasing the main parachute from the container comprising: a ring connected to the aft end of the missile and having a radially extending annular ledge; said container being folded over the transverse ledge; lacing extending through the folded over portion of the container for drawing the container into a tight unreleased condition about the ring; and means carried by the ring for releasing the lacing so as to in turn deploy the main parachute from the container.
Claim 3
Dependent Claim 101 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, a means for releasing the main parachute from the container comprising: a ring connected to the aft end of the missile and having a radially extending annular ledge; said container being folded over the transverse ledge; lacing extending through the folded over portion of the container for drawing the container into a tight unreleased condition about the ring; and means carried by the ring for releasing the lacing so as to in turn deploy the main parachute from the container.
Claim 4
Dependent Claim 101 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, a means for releasing the main parachute from the container comprising: a ring connected to the aft end of the missile and having a radially extending annular ledge; said container being folded over the transverse ledge; lacing extending through the folded over portion of the container for drawing the container into a tight unreleased condition about the ring; and means carried by the ring for releasing the lacing so as to in turn deploy the main parachute from the container.
Claim 5
Dependent Claim 34 words
The combination of claim 1 wherein: the lacing is a double cord which ends in a pair of aligned loops; and the lacing releasing means includes a retractable pin extending through the aligned loops.
Claim 6
Dependent Claim 153 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, the improvement comprising: an initial stabilizing and velocity retarding parachute releasably folded about said container; means releasably retaining the stabilizing parachute to said container, the retainer means including: a ring connected to the aft end of the missile and having an aftermost outwardly extending annular lip; a series of straps connected to the canopy of the stabilizing parachute and extending over and forward of the lip of said ring; a releasable band disposed about the straps forward of the lip for retaining the straps and the stabilizing parachute to the container; and means carried by the ring for releasing the band so that the stabilizing parachute can be released from the container; the container being constructed of a flexible material; and the stabilizing parachute having shrouds which are stitched to said container.
Claim 7
Dependent Claim 153 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, the improvement comprising: an initial stabilizing and velocity retarding parachute releasably folded about said container; means releasably retaining the stabilizing parachute to said container, the retainer means including: a ring connected to the aft end of the missile and having an aftermost outwardly extending annular lip; a series of straps connected to the canopy of the stabilizing parachute and extending over and forward of the lip of said ring; a releasable band disposed about the straps forward of the lip for retaining the straps and the stabilizing parachute to the container; and means carried by the ring for releasing the band so that the stabilizing parachute can be released from the container; the container being constructed of a flexible material; and the stabilizing parachute having shrouds which are stitched to said container.
Claim 8
Dependent Claim 77 words
The combination of claim 3 including: a means for releasing the main parachute from the container, said means comprising: said ring having a transverse annular ledge; said container being folded over the transverse ledge; lacing extending through the folded-over portion of the container for drawing the container into a tight unreleased condition about the ring; and means carried by the ring for releasing the lacing so as to in turn deploy the main parachute from the container.
Claim 9
Dependent Claim 34 words
The combination of claim 4 including: the lacing being a double cord which ends in a pair of aligned loops; and the lacing releasing means being a retractable pin extending through the aligned loops.
Claim 10
Dependent Claim 76 words
The combination as claimed in claim 5 including: the main parachute having shrouds which are connected to said ring; a deployment bag with the main parachute disposed therein, said deployment bag having eyelets; a cord releasably looped through the eyelets of the deployment bag; and a lock line connected to a shroud line of the main parachute and extending through a loop of the looped cord for locking the deployment bag until released by said container.
Claim 11
Dependent Claim 145 words
In an aerodynamic missile having a main parachute which is contained by a container at the aft end of the missile, the improvement comprising: an initial stabilizing and velocity retarding parachute releasably folded about said container; means releasably retaining the stabilizing parachute to said container; the container being constructed of a flexible material; the stabilizing parachute having shrouds which are stitched to said container; and means for deploying the main pArachute from the container, said means comprising: a ring connected to the aft end of the missile and having a radially extending annular ledge; said container being folded over the transverse ledge; lacing extending through the folded-over portion of the container for drawing the container into a tight unreleased condition about the ring; and means carried by the ring for releasing the lacing so as to in turn deploy the main parachute from the container.
