points as will become more evident below the body 202 as shown is attached to a structure such as for example a composite rocket motor casing 252 although other structures are contemplated the body 202 may be attached by adhesive through the use of fasteners or through other techniques as understood by those of skill in the art during operation of a rocket motor the casing 252 is subject to numerous forces including internal and external pressure environments which induce strain in the casing 252 the induced strain may result in elongation contraction or other flexure of the casing 252 the body 202 is designed to withstand strains similar to that seen in the rocket motor casing 252 to accommodate such strain the body 202 may be formed of an elastomeric material such as neoprene rubber although other materials are contemplated additionally forming the body of such a flexible conformable material may allow the body 202 to be installed on structures of various configurations for example by cooperatively mating with the radial surface of the rocket motor casing 252 referring to fig6 b when the rocket motor casing 252 is strained for example in an elongating fashion the body 202 is formulated configured and attached to the rocket motor casing 252 to correspondingly elongate therewith during elongation of the body 202 the openings 206 210 and.
