Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
151 words
An aerial missile comprising: a body having a generally cylindrical midsection and forward and aft contoured surfaces; said forward surface having a circular end face of smaller radius than the radius of said cylindrical midsection and joined thereto by a curved surface the profile of which is substantially a quadrant arc; said aft surface having an end face of a radius smaller than said cylindrical midsection and joined thereto by a smoothly tapered conical surface; a plurality of aerodynamic fins on said body at said forward section extending outwardly therefrom in planes at acute angles to the longitudinal surface of said body and parallel to the longitudinal axis thereof; and a like plurality of aerodynamic fins on said body at said aft surface extending outwardly in planes normal to said surface and extending from a point forward of said conical surface at least to said end face of said aft surface.
Claim 2
Dependent Claim
151 words
An aerial missile comprising: a body having a generally cylindrical midsection and forward and aft contoured surfaces; said forward surface having a circular end face of smaller radius than the radius of said cylindrical midsection and joined thereto by a curved surface the profile of which is substantially a quadrant arc; said aft surface having an end face of a radius smaller than said cylindrical midsection and joined thereto by a smoothly tapered conical surface; a plurality of aerodynamic fins on said body at said forward section extending outwardly therefrom in planes at acute angles to the longitudinal surface of said body and parallel to the longitudinal axis thereof; and a like plurality of aerodynamic fins on said body at said aft surface extending outwardly in planes normal to said surface and extending from a point forward of said conical surface at least to said end face of said aft surface.
Claim 3
Dependent Claim
25 words
The bomblet of claim 1 wherein said rear fins have forward and aft surfaces angling from forward to aft as they extend from said body.
Claim 4
Dependent Claim
33 words
