Patent number: 11485521Abstract: A spacecraft including: an engine; a thrust vector control device controlling a thrust vector as a direction of a thrust acting on the spacecraft; and a main control device configured to acquire state quantities of the spacecraft in a powered descending in which the spacecraft is guided to a target point while the engine generates the thrust, and generate a throttling command by which combustion of the engine is controlled and an operation command by which the thrust vector control device is operated. The state quantities contain a first acceleration parameter and a second acceleration parameter. The first and second acceleration parameters are calculated as coefficients A and B obtained by fitting based on acceleration of the spacecraft previously detected, supposing the following equation is satisfied between a reciprocal number 1/a of the acceleration a of the spacecraft and time t: 1/a=?At+B??(1).Type: GrantFiled: December 22, 2017Date of Patent: November 1, 2022Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Toyonori Kobayakawa, Tetsuya Nagase, Atsushi Sasaki

Patent number: 11465782Abstract: In an example, a method for deorbiting a spacecraft is described. The method includes selecting a target landing site for deorbiting the spacecraft. The method includes determining a range target and a velocity target for reaching a predicted atmospheric entry location. The method includes determining a back-propagated orbit state estimate of the spacecraft. The method includes comparing the back-propagated orbit state estimate to a known orbit state of the spacecraft to determine that the back-propagated orbit state estimate has converged with the known orbit state. The method includes calculating based on determining that the back-propagated orbit state estimate has converged with the known orbit state, (a) an estimated time of ignition for a propulsion system of the spacecraft and (b) an estimated burn velocity vector of the propulsion system using the range target and the velocity target. The method includes performing a burn pulse by the propulsion system.Type: GrantFiled: August 28, 2019Date of Patent: October 11, 2022Assignee: The Boeing CompanyInventors: John P. Ealy, Brian A. Phail, Dave Poladian

Patent number: 11420777Abstract: A rover can include a spherical shall and an avionics hub. The spherical shell defines a spherical volume and having an inner surface and an outer surface. The avionics hub is disposed within the spherical volume. The avionics hub includes an avionics shell, a data acquisition unit, and a plurality of motortrain assemblies. The avionics shell is disposed with the spherical volume of the spherical shell. The data acquisition unit is disposed within the avionics shell. Each motortrain assembly includes a motorized wheel extending at least partially through the avionics shell and in contact with the inner surface of the spherical shell, the plurality of motortrain assemblies configured to rotate the spherical shell relative to the avionics shell to move the rover.Type: GrantFiled: January 17, 2020Date of Patent: August 23, 2022Assignee: LOCKHEED MARTIN CORPORATIONInventor: Joshua William Ehrlich

Patent number: 11173409Abstract: A safe falling ride apparatus may include a rigid floor with a trap door, a net in a net frame, one or more linear actuators connected to the net frame, one or more rails on which the net frame travels up or down as driven by the actuators, a control assembly, and a deformable material. At the start of a ride event, a guest is positioned on the trap door. The trap door is opened and the guest free falls until reaching the net, which catches the guest and begins a controlled descent as determined by the actuators, until the guest and the net reach the deformable material. The guest and net keep descending into the deformable material as their energy is dissipated and their speed decreased, until the guest reaches the ride end floor. The control assembly detects when the guest has left the ride, and repositions the equipment to the start position for the next guest.Type: GrantFiled: December 9, 2020Date of Patent: November 16, 2021Inventor: Joshua S. Cohen

Publication number: 20150034770Abstract: A system, method, and apparatus for a vented launch vehicle adaptor (LVA) for a manned spacecraft with a “pusher” launch abort system are disclosed. The disclosed LVA provides a structural interface between a commercial crew vehicle (CCV) crew module/service module (CM/SM) spacecraft and an expendable launch vehicle. The LVA provides structural attachment of the module to the launch vehicle. It also provides a means to control the exhaust plume from a pusher-type launch abort system that is integrated into the module. In case of an on-pad or ascent abort, which requires the module to jettison away from the launch vehicle, the launch abort system exhaust plume must be safely directed away from critical and dangerous portions of the launch vehicle in order to achieve a safe and successful jettison.Type: ApplicationFiled: July 22, 2014Publication date: February 5, 2015Inventor: Robert E. Vandervort

Patent number: 8939407Abstract: An apparatus comprising a first structure, a second structure, a first layer, and a second layer. The first structure has a first plurality of channels extending towards a number of edges of the first structure. The second structure has a second plurality of channels extending towards a number of edges of the second structure. A first side of the first structure is connected to a first side of the second structure. The first plurality of channels and the second plurality of channels have an orientation with respect to each other. The first layer is connected to a second side of the first structure. The second layer is connected to a second side of the second structure.Type: GrantFiled: February 15, 2011Date of Patent: January 27, 2015Assignee: The Boeing CompanyInventors: Michael James Robinson, Michael Leslie Hand

Patent number: 8690104Abstract: A method of landing a capsule-spacecraft having a crew compartment containing crew, light cargo, and whatever other elements are associated with crew safety and comfort during emergency recovery, such as survival equipment and a service component including any propulsion components, heat shield, heavier structure, or other equipment not directly connected with the crew component. In the event of a propulsion system failure, the crew compartment component is immediately separated from the service component, either by automatic or crew action. One or more parachutes are then deployed by rapid methods, such as rocket extraction, from the crew compartment. Because the space craft is separated into two parts the weight of the parachutes is reduced in proportion as the weight of the crew compartment is to the total capsule-spacecraft.Type: GrantFiled: December 12, 2011Date of Patent: April 8, 2014Assignee: HMX, Inc.Inventor: Gary C.
