Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
68 words
A rocket system comprising: a launch tube, a projectile mounted by sabot means within said launch tube, and a rocket mounted in said launch tube and having energy absorber means at one end in spaced relation to said projectile, said energy absorber means causing velocity amplification to be imparted to said projectile by a momentum transfer between the rocket and the projectile when the rocket has been fired.
Claim 2
Dependent Claim
68 words
A rocket system comprising: a launch tube, a projectile mounted by sabot means within said launch tube, and a rocket mounted in said launch tube and having energy absorber means at one end in spaced relation to said projectile, said energy absorber means causing velocity amplification to be imparted to said projectile by a momentum transfer between the rocket and the projectile when the rocket has been fired.
Claim 3
Dependent Claim
34 words
A rocket system as set forth in claim 1, wherein said energy absorber means includes a plate and resilient means for storing energy during momentum transfer to said projectile to cause the velocity amplification.
Claim 4
Dependent Claim
16 words
A rocket system as set forth in claim 2, wherein said resilient means includes a spring.
Claim 5
Dependent Claim
21 words
A rocket system as set forth in claim 3, wherein said projectile is made as a rod penetrator of solid material.
Claim 6
Dependent Claim
19 words
A rocket system as set forth in claim 4, wherein said projectile is streamlined in configuration and has fins.
