TLDR
In this article, the authors proposed a solid propellant rocket motor with a controlled rate of thrust buildup to a desired thrust level by the combined utilization of a regressive-burning controlled flow solid- propellant igniter and a progressive-burning main solid-propellant charge, where the igniter is capable of operating in a vacuum and sustaining the burning of the propellant below its normal L* combustion limit until the burning propellant surface and motor chamber pressure has increased sufficiently to provide a stable motor chamber.Abstract:

Patent
Igniting rocket propellants under vacuum conditions
TL;DR: Improved igniter compositions for rocket motors are provided which, when cured, are nonvolatile and are capable of igniting under vacuum conditions and burning steadily at reduced pressures.
Patent
Igniter pellet cup
TL;DR: A consumable sealed plastic cup containing ignition pellets is assembled into end cap at the forward end of a solid fuel rocket motor with sufficient clearance to allow leak test gas to bypass it and thereby expose the port seals of the through bulkhead initiators for leak checking as discussed by the authors.

Mechanical and insulating connection between a nozzle and the filament-wound casing of the combustion chamber of a solid propellant rocket motor
TL;DR: In this paper, the authors proposed a mechanical and insulating connection between a filament-wound casing, constituting a wall for the combustion chamber of a solid propellant rocket motor, and a hot nozzle made from a heat-conducting refractory material.
Patent
Distributed erosion region rocket motor nozzle
TL;DR: In this article, the erosive forces created by the combustion products are longitudinally distributed over the nozzle core so that the nozzle's smallest area remains substantially constant in spite of the erosion.
Patent
Throat retention apparatus for hot gas applications
TL;DR: In this article, a hot gas valve is provided that includes a housing, an insert, and a retainer, which is coupled between the housing and the insert and configured to retain the insert within the housing throat section.
