Abstract
Abstract A tandem rocket launcher is provided by mounting plural rockets in an elongated launch tube with associated guide and launch equipment for each rocket. A conical shield is placed between the rockets which deflects exhaust gases generated by firing the forward rocket away from the rearward rocket. The shield is then removed by firing of the subsequent rocket or pivoting of two halves of the deflector away from the path of travel of the subsequent rocket.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
In a tandem rocket launcher means for positioning plural axially aligned rockets having exhaust means interspersed along a tube for exhausting rocket gases from a first rocket before they impinge a second rocket behind the first, the improvement comprising: a conical exhaust gas deflector adjacent the gas exhausting means effective to prevent launched rocket exhaust gas flow from said first rocket toward said second rocket by directing said gases out of said exhaust means interspersed along said tube, said gas deflector being bifurcated with each half rotatable toward the interspersed means about axes positioned external to the base of the conical deflector for symmetrically dispersing said exhaust gas flow, thereby providing for even back pressure on said first rocket.
Claim 2
Dependent Claim
119 words

Claim 3
Dependent Claim
32 words
The improvement of claim 1 wherein each half of the deflector is individually coupled to a lever and actuator for selectively rotating the section out of the path of the second rocket.
Claim 4
Dependent Claim
14 words
The improvement of claim 1 further including independent rotating means for each deflector half.
Claim 5
Dependent Claim
37 words
The apparatus of claim 3 wherein said tube comprises internal and external shells, said first and second rockets being mounted within said internal shell and wherein said independent means is located between said outer and inner shells.
