    Abstract: The present disclosure is directed to a solid propellant charge for rocket engines having a short burning time, e.g. from 70 to 1,000 milliseconds which comprises a plurality of windings substantially equally spaced from one another at a prescribed distance, e.g. from about 0.2 to about 10 mm. and exhibiting a definite geometric shape, each of said windings consisting essentially of a supporting member embedded in an adhesive layer and a layer of propellant adhered to both sides of said adhesive layer.

    Abstract translation: 本公开涉及具有短燃烧时间的火箭发动机的固体推进剂装料，例如。 从70至1,000毫秒，其包括以规定距离彼此基本上等距间隔的多个绕组，例如， 约0.2至约10mm。 并且具有确定的几何形状，每个所述绕组基本上由嵌入在粘合剂层中的支撑构件和粘附到所述粘合剂层两侧的推进剂层组成。

    CPC classification number: F02K9/28 ,  F02K9/12

    Abstract: THE ENGINE IS PROVIDED WITH A PLURALIY OF PROPELLANT CHARGES, SOME OF WHICH HAVE BOOSTER PROPELLANT DEFINING THEIR TOTAL BURNING SURFACE AND SUSTAINING PROPELLANT WHERE OTHERS HAVE ONLY BOOSTER PROPELLANT. THE CHARGES ARE ANNULAR TO SURROUND A CENTRAL TUBE HAVING RADIAL APERTURES COMMUNICATING WITH THE BURNING SURFACES FOR CONDUCTING THE EXHAUST CENTRALLY TO A COMMON NOZZLE MEANS FOR ACCOMMODATING THE IGNITION BOOSTERS TO TRANSFER THE IGNITION FROM A CENTRAL IGNITION CHARGE LOCATED AT THE END OF THE TUBE OPPOSITE FROM THE NOZZLE MEANS. PREFERABLY THE CHARGES HAVING BOTH BOOSTER AND SUSTAINER PROPELLANT

    ARE IDENTICAL AND THE CHARGES HAVING ONLY BOOSTER PROPELLANT ARE IDENTICAL, WITH EACH HAVING A CENTRAL BAND MOUNTED BETWEEN ADJACENT THIN WALL TUBES ALONG THE INTERIOR SURFACE OF THE COMBUSTION CHAMBER FOR DETERMINING THE AXIAL UNIFORM SPACING OF THE CHARGES. THE CHARGES PREFERABLY HAVE MEANS INSULATING THEIR ANNULAR INNER AND OUTER CYLINDRICAL SURFACES SO THAT THEY ARE DUAL AXIALLY SPACED END BURNERS.
