A burst diaphragm sequence valve which effectively combines the structure a burst diaphragm with that of an ordinary swing check valve, the pivot of the ordinary swing check valve being replaced by an integral flexural hinge. The sequence valve provides a way to sequentially burn solid propellant hot gas generators which exit into a common gas manifold, thereby enabling gas-powered devices to operate for a longer time than the duration of one gas generator burn.

A high-temperature thermal insulation quilt assemblage consisting of an inner quilt and an outer quilt, each cut according to a pattern so as to conform to the shape and wrap around an object having a surface temperature as high as 3000.degree. F. during operation. The inner and outer quilt each include a silicic-impregnated quartz fabric case, multiple blankets of ceramic insulation material, and quartz-fiber thread cross-stitching to reduce quilt thickness. The inner quilt additionally includes a tantalum foil inserted between two blankets of ceramic insulation material, and sewn-on tie straps. The outer quilt additionally includes sewn-on lacing strips for securing outer quilt abutting edges together; the outermost surface is coated with silicone rubber.
