Patent number: 11680543Abstract: Various implementations of an extinguishable, solid propellant divert system for a flight vehicle are disclosed. Also disclosed are methods for using the divert system to control the flight of a flight vehicle. In one implementation, a divert system includes a hot gas generator pneumatically linked to one or more divert thrusters and an extinguishment valve. The extinguishment valve can be opened to rapidly depressurize the hot gas generator and extinguish the solid propellant burning inside. In another implementation, a method of controlling the trajectory of the flight vehicle includes repeatedly igniting and extinguishing the solid propellant in a hot gas generator and using the hot gas to provide divert thrust for the flight vehicle.Type: GrantFiled: September 14, 2021Date of Patent: June 20, 2023Assignee: Valley Tech Systems, Inc.Inventors: Russell Carlson, Dustin Barr, Allen Yan, Justin Carpenter

Patent number: 11448165Abstract: An attitude control system for a guided missile includes a gas generator, an accumulator coupled to the gas generator, and a valve positioned between the gas generator and the accumulator. The gas generator contains propellant that burns to provide hot gas to pressurize the accumulator. The valve is opened to recharge the accumulator with hot gas and closed when it is full. A vent valve can be included to extinguish the propellant in the gas generator. The accumulator can be coupled to thrusters that use the stored hot gas to adjust the attitude of the guided missile.Type: GrantFiled: March 23, 2020Date of Patent: September 20, 2022Assignee: Valley Tech Systems, Inc.Inventors: Russell Carlson, Dustin Barr, Allen Yan
