    摘要: A solid cylindrical centripetally burning propellant element comprises four lobes, the cross-section of each lobe comprising a convex arc tangential to a right circular cylinder circumscribing the element, of radius R, the radius of the arc being equal to the combustion thickness e of the element. The element has only two combustion residues by which it may be secured in the combustion chamber of a rocket engine.

    摘要: A solid cylindrical centripetally burning propellant element having an instantaneous combustion surface of substantially constant magnitude exhibits rotational symmetry of order n (2 .ltoreq. n .ltoreq. 15) about a longitudinal axis. The cross- section of the element presents n convolute branches, each terminating in a semi-circular arc of radius equal to the combustion thickness e, the cross-section being the envelope generated by a circle of radius e which rolls on a n-symmetrical base-line comprising a polygon having n concave sides forming n similar cusps extended by respective curved arms. The contour of the polygon generatrix defines the outer limit of the single combustion residue of the element, by which the element may be secured in the combustion chamber of a rocket engine.

    摘要: A gas generant tablet (24) for use in a linear inflator (10). The tablet (24) includes a body portion (102) having a first end (104), a second end (106), and a longitudinal axis (T). A first projection (108) extends from the tablet first end (104) in a first direction, with at least a portion of the first projection (108) extending non-orthogonally with respect to the tablet longitudinal axis (T). A second projection (112) extends from the tablet second end (106) in a second direction generally opposite the first direction. At least a portion of the second projection (112) extends non-orthogonally with respect to the tablet longitudinal axis (T). The tablet (24) is shaped such that a cavity (25) is formed between adjacent tablets (24) when the tablets are stacked within a combustion chamber of the inflator (10). Also disclosed is an inflator (10) for use in an inflatable vehicle occupant protection system (200). The inflator (10) includes a longitudinal enclosure (22) having a substantially uniform cross-sectional area along at least a portion of the enclosure. The enclosure (22) defines an interior cavity (22c) for containing a quantity of a gas generant composition therein, and includes a plurality of apertures (40) formed therealong to enable fluid communication between the enclosure interior cavity (22c) and an exterior of the enclosure. A plurality of gas generant tablets (24) is stacked along the enclosure (22), the tablets being shaped such that a cavity (25) is provided between adjacent tablets (24) when the tablets are stacked within the enclosure (22).
