Patent number: 7210654Abstract: An unmanned airborne reconnaissance system, the unmanned airborne reconnaissance system including a lightweight, portable, powered aircraft and a foldable launch rail, the aircraft, in a broken down condition and the launch rail in a broken down condition fitable inside a box, the box capable of being carried by one man. The launch system includes an elongated launch rail with the carriage assembly, and a propulsion means for accelerating the carriage assembly from one end of the launch rail to the other. The carriage assembly releasably engages the aircraft so as to propel the aircraft from one end of the launch rail to the other. The propulsion may be by a cartridge that explodes and releases a gas through a cylinder, or by elastic cords. The aircraft is guided through the air either by a programmed onboard computer which controls the control surfaces of the aircraft and/or by remote control. The aircraft typically contains a camera for recording and transmitting images received from the ground below.Type: GrantFiled: July 23, 2003Date of Patent: May 1, 2007Assignee: Mission Technologies, Inc.Inventors: Beverly Cox, Hampton Dews, Nicholas Nyroth

Patent number: 7207520Abstract: An advanced aperture inlet (AAI) uses a three-dimensional, mixed compression inlet design derived from computational fluid dynamics (CFD) by streamline tracing a supersonic section from an axisymmetric mixed compression inlet solution. The axisymmetric design is used to obtain a CFD solution with slip wall boundaries at the inlet design point and serves as a flow field generator for the AAI. The AAI geometry is obtained by projecting a desired aperture shape onto a surface model of the external oblique shock. Streamline seeds are located on the projected aperture segments and transferred into the CFD solution space. The streamlines generated by these seeds inside the CFD solution space are then used as a wireframe to define the supersonic diffuser back to the throat location. Traditional design techniques are then used to define the subsonic diffuser from the inlet throat to the engine face.Type: GrantFiled: May 31, 2005Date of Patent: April 24, 2007Assignee: Lockheed Martin CorporationInventors: Brian F. Lundy, John D. Klinge, Bradley C. Leland

Patent number: 7207523Abstract: A power/data bus for conducting at least one of data and power signals to a variety of different locations on a mobile platform. The bus has a plurality of discrete connection ports, and at least one conductive cable. The power/data bus extends across an area where access to at least one of data and electricity is desired. The discrete connection ports are spaced apart at different locations along the power/data bus. The conductive cable extends through the power/data bus and is connected to at least one of the discrete connection ports. The conductive cable conducts at least one of power and data signals between the discrete connection ports and a data/power source. At least one of the connection ports are operable to cooperate with a connector of an external device to supply at least one of power and data signals to the external device. The power/data bus, when used in an aircraft passenger cabin, eliminates the need to extend individual data and/or power cables to or between each passenger seat group.Type: GrantFiled: September 8, 2004Date of Patent: April 24, 2007Assignee: The Boeing CompanyInventors: Kevin S Callahan, Trevor M Laib, Bradley J Mitchell, James T Henley

Patent number: 7198224Abstract: An airframe includes an energy absorbing structure with a frame, a beam mounted to the frame at a rotational joint and a collapsible member. In response to reaching a predetermined threshold load value during a high sink rate impact event, the collapsible member will collapse under an aft section of the upper deck. The rotational joint operates as a virtual hinge such that a forward section of the upper deck deforms in a predictable manner. As the upper deck supports the high mass systems, the high mass components are less likely to separate from their mounting and penetrate into the crew compartment and the main rotor system will tilt aft away from the crew compartment to minimize the likelihood that the rotor blades may penetrate the crew compartment.Type: GrantFiled: February 24, 2005Date of Patent: April 3, 2007Assignee: Sikorsky Aircraft CorporationInventors: William Townsend, Bruce Fredric Kay

Patent number: 7191985Abstract: Vibrations due to excitation of the natural modes of an aircraft's body are suppressed by an active multi-axis modal suppression system. Dedicated sensors are positioned in the aircraft at optimal locations for sensing modal induced vibrations. The sensor produced signals are processed through control logic which, in response thereto, and in response to aircraft inertial, velocity and altitude related signals produces output control signals. The control signals effect control surface deployment creating forces to suppress the natural mode induced vibrations on multiple geometric axis's. More particularly, a symmetric and anti-symmetric control surface deployments are used on one or more geometric axis'to damp lateral, longitudinal, vertical and most importantly torsional vibrational modes.Type: GrantFiled: July 12, 2005Date of Patent: March 20, 2007Assignee: The Boeing CompanyInventors: Kioumars Najmabadi, Chuong B.

Patent number: 7191984Abstract: A thermal management system for a spacecraft module includes a baseplate and wall system that is precharacterized to provide a given level of thermal performance regardless of an orientation of the spacecraft relative to a source of solar energy. The system is characterized at a worst-case hot orientation, and at a worst-case cold orientation. The characterization provides a maximum temperature and a minimum temperature of components mounted on the baseplate as a function of the height of the walls. The height of the walls is selected to provide a suitable temperature range for the components, based on the power dissipation of the components. The system is designed to be symmetric, so that this temperature range is assured regardless of the orientation of the spacecraft.Type: GrantFiled: June 14, 2005Date of Patent: March 20, 2007Assignee: AeroAstro, Inc.Inventors: Mark Carl Barton, Jonathon Miller

Patent number: 7185844Abstract: Systems and methods for guiding an object may comprise improved guidance laws that improve the effectiveness of the PRONAV guidance law. The improved guidance laws may utilize the same parameters as the PRONAV law and may be algorithmically simpler than conventional guidance laws because they may not be based on information about an intercept point or time-to-go. The improved guidance laws may be developed based on the Lyapunov method. The improved guidance laws may augment the PRONAV law and may provide additional components based on the negative definiteness of the derivative of the Lyapunov function. The additional components may be determined based on the partial stability of the guidance system dynamics under consideration with respect to the line of sight derivative. A comparative analysis of the improved guidance laws with the PRONAV laws, for example, may show that the improved guidance laws guarantee shorter homing time requirements and larger capture areas.Type: GrantFiled: April 30, 2004Date of Patent: March 6, 2007Assignee: Technology Service CorporationInventor: Rafael T. Yanushevsky

Patent number: 7182292Abstract: A seat having a seat leg assembly for use on a mobile platform, especially on an aircraft. The seat comprises a front seat leg, a rear seat leg, and a spreader bar coupled to and extending between the front seat leg and the rear seat leg. The spreader bar has a door. The door is movable between a closed position in which the door prevents access to areas beneath the spreader bar and an open position in which the door permits access to areas beneath the spreader bar. In this manner, the open door allows an installer to grasp electrical cabling beneath the spreader bar and feed the cabling through a hole in the door so that the cable can be connected a connection point on or adjacent to the seat track.Type: GrantFiled: July 23, 2004Date of Patent: February 27, 2007Assignee: The Boeing CompanyInventors: Daniel J Howard, Kevin S Callahan, Samuel J Feist, Bradley J Mitchell, Trevor M Laib, James T Henley
