Methods Of Controlling Thrust In A Rocket Motor
US Patent:
8539751, Sep 24, 2013
Filed:
Apr 14, 2010
Appl. No.:
12/760069
Inventors:
Cary Lee Cover - Warwick MD, US

Assignee:
Alliant Techsystems Inc. - Arlington VA
International Classification:
B63H 11/00
US Classification:
60204, 60228, 23926525
Abstract:
A propulsion thrust control system and method for controlling thrust in a rocket motor includes configuring valves of an energized rocket motor to an initial total valve area according to a total thrust command. The total thrust command is converted into a commanded propellant mass flow discharge rate. A varying total valve area is computed from an error between the commanded propellant mass flow discharge rate and a calculated propellant mass flow discharge rate. The valves are reconfigured according to a distribution of the varying total valve area. The propulsion system includes a pressure vessel with valves and a controller for regulating the valve area according to a propellant mass flow discharge rate from the pressure vessel.

International Classification:
B60R 11/06
US Classification:
224401
Abstract:
Systems and methods for mounting and using various different accessories on a robotic system such as a unmanned ground vehicle (UGV). A tool library may include interchangeable modules, each module having a number of tool holders. Electronic components may be mounted to each of the modules adjacent to each of the of tool holders that identify the module and tool that is associated with the tool holder. The UGV may have a reader that is capable of reading the electronic components to determine the module and tools that are available for use on the UGV.
