Patent number: 4341173Abstract: A propulsion motor for an underwater vehicle such as an anti-submarine weapon. The motor includes a propulsion chamber into which water is admitted and then rapidly expelled through an exhaust nozzle, developing thrust to propel the vehicle. Gas generators are used to develop the successive hydropulses to expel the water following each filling of the motor chamber with water. In one particular embodiment of an anti-submarine weapon which is directed through the air to the vicinity of a submarine by a rocket motor, the hydropulse underwater propulsion system can use the same chamber as the rocket motor.Type: GrantFiled: March 3, 1980Date of Patent: July 27, 1982Assignee: General Dynamics, Pomona DivisionInventors: Allen C.

Patent number: 4337560Abstract: An automated assembly, maintenance, and repair system for the construction of a large space structure. The space structure comprises a plurality of trusses and truss junctions that in turn are made up of a plurality of individual struts and nodes. The truss assemblies are progressively built by an assembler trolley as the trolley crawls along the constructed truss. The trolley comprises a forward crawler and a rear crawler joined by an articulated coupler. The crawlers are carried along the structure by belt transports incorporating grippers that engage the truss structure at the nodes. Manipulator arms for strut and node assembly are located on the forward crawler, and the majority of control, power, and communication systems are located in the rear crawler. Cargo canisters filled with component parts for constructing the space structure are carried by the forward crawler. The space structure configuration is determined by the arrangement of the individual struts and nodes during the assembly process.Type: GrantFiled: December 17, 1979Date of Patent: July 6, 1982Assignee: General Dynamics, Convair DivisionInventor: Paul Slysh

Patent number: 4337427Abstract: In a closed loop servo system in which the input signal is inaccessible and not available for measurement, but the error signal and output signal are both accessible and measurable, a filter configuration is provided which can be inserted into the error signal path of the system to reduce the undesirable effects of noise or other unwanted signals without appreciably affecting the closed loop dynamics of the overall system. In the generalized system a filter having the characteristics g(s) in LaPlace notation is inserted into the error signal path of the system to filter selected components of the error signal. A second filter having the characteristics h(s) which satisfies the equation g(s)+h(s)=1, is coupled between the output signal and the output of the filter having the characteristics g(s).Type: GrantFiled: December 22, 1980Date of Patent: June 29, 1982Assignee: General Dynamics, Pomona DivisionInventor: Inge Maudal

Patent number: 4332066Abstract: A tool holder has compliance features that allow a hole to be drilled at high tolerances by a remote controlled control arm. The holes are drilled in a workpiece that has a template secured over it with guide holes for positioning the holes to be drilled. A self-feeding drill of the type that will simultaneously rotate and advance a drill bit is mounted in a support. A sleeve is carried at the forward end of the support for enclosing the drill bit. An index carriage moves the support forwardly into the guide hole after the control arm has substantially aligned the sleeve with the guide hole. Compliance mechanisms in the support allow the entire drill, drill bit and sleeve to move as a unit a limited amount parallel to and angularly with respect to the template and the indexing carriage, to allow advancement of the sleeve into the guide hole even though there may have been initial misalignment. The compliance mechanisms preferably include an inner guide member mounted within an outer guide member.Type: GrantFiled: January 7, 1980Date of Patent: June 1, 1982Assignee: General Dynamics CorporationInventors: Samuel I.

Patent number: 4327624Abstract: Disclosed is a launcher-missile system with the launcher tube provided with a configuration on its aft end so as to reduce the tip-off rates of the system. The configuration comprises the formation of an open sector in the flared end of the launcher tube so that a portion of the exhaust gases exiting from the tube, as the missile is fired, does not impinge on that sector of the flared end and thus an impulse caused by the impinging of the gases on the remainder of the flared end reduces the tip-off rate.Also disclosed is a means in which the size and location of the open sector can be selected depending upon the desired change in magnitude and direction of the tip-off rate.Type: GrantFiled: June 23, 1980Date of Patent: May 4, 1982Assignee: General Dynamics, Pomona DivisionInventor: Edward T.
