Abstract: An explusion system in which an inner tank is nested within a second and er tank to provide a very compact and space saving arrangement for an expulsion system for a rocket with the first and inner tank as well as the second and outer tank being reinforced with composite material to provide a space saving and relatively light expulsion system for a rocket.

Abstract: A process for making lightweight composite launcher pods in which a multicity of launcher tubes are wound on a multiplicity of mandrels and mounted in end structures of a mold and assembled into a generally rectangular mold structure and applying syntactic foam about the tube and spacer structure within the mold and finally curing the structure within the mold to provide a unitary lightweight composite launcher pod.

Abstract: A non-obstructing laser beam sampling meter which measures the power output of a laser by utilizing the optogalvanic effect in the electrode space of a glow discharge which is made to operate on the left side of the Paschen curve where breakdown voltage increases with decreasing pressure.

Abstract: A dynamic alignment fixture which has a pivot plate which is adapted to h a rate gyro mounted thereon and a base which is adapted to be mounted on a rate table with means for adjusting the pivot plate relative to the base plate and rate table to allow for the testing of the amount of misalignment of an input axis of the rate gyro that is mounted thereon to allow misalignment data to be gathered on high-drift-rate gyros.

Abstract: A curvilinear solid propellant gas generator which includes a housing that as a diameter or width that is larger than the length of the gas generator and with a curvilinear solid propellant grain mounted therein to provide a long burning time propellant with a short length housing.

Abstract: A low flow calibrator in which a closed manifold type system is provided that includes a differential pressure transducer with null indication with valving means for opening the system to the atmosphere and for initially nulling the differential pressure transducer and then closing the system, the system includes means for connecting a source with a standard leak therein to the system and the system has an adjustable bellows for varying the volume of the system and for causing the differential pressure transducer to be adjusted to a null position after the system has been closed off by the valve means, and the system has a bourdon tube that can be mechanically adjusted to increase the volume of the system with indicator means being connected relative to the bourdon tube to indicate the amount of volume increase by actuating a closed end of the bourdon tube to enable the system to be used to calibrate the amount of leak from the source.

Abstract: A rocket motor structure which includes a head closure and an aft section th a multiplicity of composite tubes mounted therebetween to define a multiplicity of small chambers for providing an overall rocket motor and in which the aft section includes a nozzle structure for the composite tubes and provides attached fins for guiding and stabilizing the structure.
