Abstract: An apparatus and method for thermal protection is provided. A thermal protection apparatus includes a porous layer attached to an inner structural member requiring thermal protection. The porous layer serves as both a cooling air plenum and a transpiring medium. The porous layer may include a low strength ceramic foam layer. Thermal protection may be achieved by flowing cooling air the length of the porous layer. The voids in the porous layer may be sized to less than 50 ?m, producing uniquely efficient thermal protection due to micro-fluidic effects in the air flowing through the layer. A semi-permeable layer may be attached to the outer surface of the porous layer. The semi-permeable layer may prevent erosion of the porous layer and may transform the porous layer into a plenum by making the majority of the cooling air flow the length of the porous layer before exiting through small holes drilled or punched through the semi-permeable layer.

Abstract: An aircraft comprises a wing tip device, for example a winglet, a raked-tip device, a wing tip fence or a planar wing extension, mounted in the region of the tip of a wing on the aircraft. The wing tip device is rotatably moveable between a first position and a second position, in which the upward lift produced by the wing or the wing tip device is reduced. During flight, the bending moment at the root of the aircraft wing therefore changes in dependence on the position of the wing tip device. The maximum bending moment in the aircraft wing sustained during high-load conditions is thereby reduced, allowing the structural mass of the aircraft to be reduced.

The lifting device includes a frame, attachment devices that attach the frame of the lifting device to overhead support frames, and a driving device that moves the frame of the lifting device up the attachment devices. The frame of the lifting device receives the frame that supports the module as the frame of the lifting device is moved by the driving device.

Abstract: A personal flying apparatus has a substantially horizontal element having a lower surface adapted to acted on by a wind upwardly so as to produce a wind-generated lifting force, and an inflatable element connected with the substantially horizontal element and filled with gas which is lighter than air so as to produce a gas-generated lifting force, so that both the wind-generating lifting force and the gas-generating lifting force jointly lift the flying apparatus to allow it to fly.

Abstract: A positioning boom disposed between a space-based observatory platform and its instrument payload provides thermal and dynamic isolation as well as fine pointing and momentum control. The inventive system isolates a sensitive payload from a warm, dynamically noisy spacecraft, which includes a sunshield. Isolation is required in terms of dynamics and heat flow, both in terms of the absolute level and its variance (thermal isolation). The present invention provides intrinsic control over momentum buildup (which is due to the separation of the center of pressure from the center of mass). The space-based platform also provides a view (field of regard) to at least half the sky (in the anti-sun direction).

The aircraft further includes a power plant mounted on the airframe. In addition, the aircraft includes at least two propellers rotatably mounted on the airframe and powered by the power plant for moving the aircraft in a generally forward direction during operation of the propellers. Also, the aircraft includes at least two counter-rotatable fan sets mounted on the airframe and powered by the power plant for providing upward lift to the aircraft during operation of the fan sets.

Abstract: A system for reducing plasma induced communication disruption is disclosed. The system utilizes an electrophilic gas injectant, bent reentry vehicle nose shaping and a number of flaps configured to provide 3-axis steering capability. Injecting electrophilic gas injectant into plasma accomplishes reduction of plasma induced communication disruption by removing free electrons in the plasma which causes the communication disruption. For reentry vehicles, a bent biconic nose also reduces plasma effect during reentry. By combining electrophilic gas injection and bent nose shaping, the system reduces and/or eliminates plasma induced communication disruption, such as, GPS communication blackout, for a reentry vehicle during reentry. Furthermore, the 3-axis steering capability renders the reentry vehicle more maneuverable. Performance of the reentry vehicle during reentry, such as, target accuracy, is thus improved.

Abstract: There is provided a ring tail for a ballistic projectile and an associated method that facilitate maneuverability of the ballistic projectile. The ring tail comprises a ring member having a generally cylindrical wall and at least one rod joined to an aft section of the ballistic projectile and the ring member. The rod defines an adjustable length, wherein an actuation device joined to the at least one rod adjusts the length to thereby maneuver the ballistic projectile during flight. The ring tail may include generally radially oriented panels and may also include a second ring member joined to the distal ends of the panels such that the ring members are coaxial. Once the projectile has been launched, the ring member extends aftward to provide aerodynamic stability, which may be measured by a guidance sensor in electronic communication with the actuation device that adjusts the length of the at least one rod.

Abstract: An efficient flying device having flapping wings, an ornithopter, which uses many of the principles seen in bird flight, is presented herein. The wings are highly flexible, translationally stable and oscillate as a natural pendulum. Described as a springboard, the wings have a singular natural frequency, and a pumping means drives the wings at that frequency. Feedback means are described by which to accomplish this, whereby deflection of the wing affects an escapement mechanism which controls the timing and direction of the pumping means. Wing design is described whereby camber, flexure, torsion and directionality of wing components affect efficient propulsion, lift and differential reactivity with air during downstrokes and upstrokes. A crook element in the wing spar at a location proximal to the body of the device redirects vertical oscillation to horizontal.

Abstract: An asymmetrical bulkhead for a pressure vessel, tank or other storage facility is disclosed. The bulkhead is configured so that there is a high region extending past a cylindrical portion of the vessel on one side of the bulkhead, with a contour of the bulkhead transitioning from the high region to a low region within the last cylindrical region. Such a bulkhead configuration allows two cylindrical pressure vessels to be nested together in end-to-end relation so as to occupy a total smaller volume than similarly sized vessels having convex ends, or to construct pressure vessels that contain a larger volume for storage than similarly sized vessels having convex ends.
