US12481287 - Monolithic attitude control motor frame and system
The patent describes a monolithic attitude control motor system featuring a structure with a central passageway and multiple cavities designed to house attitude control motors, each sharing side walls with adjacent motors. The cavities are polygonal in shape, specifically octagonal, and the overall design provides pressurization containment for the motors without requiring individual containment.
Claim 1
1 . A monolithic attitude control motor system, comprising: a monolithic structure comprising an outer surface of revolution and a plurality of side walls defining a plurality of cavities in a geometric arrangement extending radially from the outer surface of revolution, wherein the monolithic structure defines an inner surface defining a central passageway; and a plurality of attitude control motors corresponding to the plurality of cavities, such that an attitude control motor of the plurality of attitude control motors is disposed in each cavity of the plurality of cavities; wherein the plurality of side walls defines the plurality of cavities and each cavity of the plurality of cavities exhibits a polygon shape at the outer surface of revolution; wherein adjacent attitude control motors share a side wall or a portion of a side wall therebetween; wherein each of the plurality of attitude control motors provides generally no individual pressurization containment; wherein the monolithic structure provides pressurization containment for the plurality of attitude control motors; and wherein the polygon shape is an octagon and each cavity of the plurality of cavities includes: first cavity side walls tapering toward the centerline of the monolithic structure; second cavity side walls tapering toward the centerline of the monolithic structure; a respective second cavity side wall, of the second cavity side walls, having a triangle shape between the outer surface of revolution and the inner surface of the monolithic structure; and each first cavity side wall having a trapezoidal shape between the outer surface of revolution and the inner surface of the monolithic structure. a monolithic structure comprising an outer surface of revolution and a plurality of side walls defining a plurality of cavities in a geometric arrangement extending radially from the outer surface of revolution, wherein the monolithic structure defines an inner surface defining a central passageway; and a plurality of attitude control motors corresponding to the plurality of cavities, such that an attitude control motor of the plurality of attitude control motors is disposed in each cavity of the plurality of cavities; wherein the plurality of side walls defines the plurality of cavities and each cavity of the plurality of cavities exhibits a polygon shape at the outer surface of revolution; wherein adjacent attitude control motors share a side wall or a portion of a side wall therebetween; wherein each of the plurality of attitude control motors provides generally no individual pressurization containment; wherein the monolithic structure provides pressurization containment for the plurality of attitude control motors; and wherein the polygon shape is an octagon and each cavity of the plurality of cavities includes: first cavity side walls tapering toward the centerline of the monolithic structure; second cavity side walls tapering toward the centerline of the monolithic structure; a respective second cavity side wall, of the second cavity side walls, having a triangle shape between the outer surface of revolution and the inner surface of the monolithic structure; and each first cavity side wall having a trapezoidal shape between the outer surface of revolution and the inner surface of the monolithic structure. first cavity side walls tapering toward the centerline of the monolithic structure; second cavity side walls tapering toward the centerline of the monolithic structure; a respective second cavity side wall, of the second cavity side walls, having a triangle shape between the outer surface of revolution and the inner surface of the monolithic structure; and each first cavity side wall having a trapezoidal shape between the outer surface of revolution and the inner surface of the monolithic structure.
