Abstract: A pulse detonation wave engine (PDWE) detonation system provides for optical ignition. The detonation system has a plurality of detonation banks, where each detonation bank has a plurality of detonation chambers for receiving a fuel/oxidizer mixture from a propellant source. An optical ignition subsystem generates a plurality of optical pulses. The detonation system also has an optical transport subsystem for transporting the optical pulses from the ignition subsystem to the chambers, where the optical pulses ignite each fuel/oxidizer mixture such that the chambers detonate in a desired order. This allows the banks to be sequentially detonated and the chambers within each bank to be simultaneously detonated, without the increased tankage and toxic ignition associated with conventional approaches.

Abstract: A rotary-wing system which generates a directed ion field to propel a fluid along a rotary-wing to control at least one boundary layer characteristic.

Abstract: A method of fabricating a rolling bladder propellant tank assembly includes providing a pair of half-domes comprising a nanophase metallic material and a bladder formed of a ductile metallic material. A bladder support ring extends from at least one of the pair of half-domes. The pair of half-domes are positioned together to form a cavity therein with a portion of the bladder trapped between the pair of half-domes adjacent to the bladder support ring, wherein the bladder is positioned within the cavity. A seal is formed between the pair of half-domes and the bladder by friction stir welding. A friction stir welding pin used to form the seal is aligned with the bladder support ring during the friction stir welding operation.

Abstract: A section of a gas turbine engine includes a damper which extends from a disk between a first blade and a second blade to provide a dissipating vibratory motion energy in the form of friction heating.

Abstract: A combustor and injector system to inject a selected fuel into a combustor of a gas powered turbine. Generally, the injector is able to inject a selected fuel into a stream of an oxidizer to substantially mix the fuel with the oxidizer stream before any of the fuel in the fuel fan reaches an auto ignition temperature. Therefore the fuel may be substantially combusted at once and without any substantial hot spots.

Abstract: A system for substantially continuously providing a solid material, for example pulverized coal, to a pressurized container. The system provides the solid material to a first container of a first pressure elevated above an initial pressure of the solid material. Generally, a screw conveyor augmented with a jet port is used to move the material where the jet port provides a gas to provide a make-up volume of the solid material. The system also provides the material to a second high pressure container after the material has been formed into a slurry. Therefore, the solid material may be substantially continuously provided in a system to a high pressure container.

Abstract: An expander heat exchanger cycle system provides a fuel or oxidizer routed through a heat exchanger to cool and condense a coolant/turbine drive fluid.

Abstract: A combustor assembly for a gas powered turbine includes a premix section to mix a first selected volume of fuel with a selected oxidizer. The premix section includes an injector plate that includes a porosity according to selected characteristics, such as pore size, pore density, pore distribution, and other selected characteristics. Therefore, the fuel may be provided through the porous plate to the premix area in a selected uniform flux.

Abstract: A rotary engine which provides a supplemental phase of compression between a first phase of compression and a second phase of compression.

Abstract: A reactor vessel liner system includes a liner having a plurality of first conduits and a plurality of second conduits for conveying a coolant. The plurality of second conduits is located at least partially within corresponding ones of the plurality of first conduits.

Abstract: A blade includes an airfoil portion which defines at least one cavity with a damper located within the cavity, the damper includes a corrugated surface.

Abstract: A heliostat includes a joint with a range of motion in both elevation and azimuth of more than 90 degrees.

Abstract: A method for regenerating a solid reactant includes streaming the solid reactant into an inlet port of a contact or vessel and heating the solid reactant inside the contactor vessel, streaming a purge oxidant into an oxidant port of the contactor vessel to reduce a partial pressure of gas released from the solid reactant, venting the gas from a gas port of the contactor vessel, and removing the solid reactant from a discharge port of the contactor vessel.

Abstract: In some embodiments fastening apparatus includes a threaded fastening element adapted to be threaded into a hole provided in a first component, the threaded fastening element including a locking collar that is defined by at least one outer peripheral surface, and a locking washer adapted to fit within a recess formed in the component to limit rotation of the threaded fastening element once the element is threaded into the component hole, the washer including an inner opening defined by at least one inner peripheral surface and a non-circular outer shape defined by an outer peripheral surface, the inner opening being adapted to receive the locking collar such that the at least one outer peripheral surface of the collar can contact the at least one inner peripheral surface of the washer.

Abstract: A projectile and method of extending the range of the projectile. The projectile includes a storage tank operable to release a working fluid through an exhaust manifold to at least partially fill a wake aft of the projectile during projectile flight.

Abstract: A pump for transporting particulate material includes an inlet, an outlet, a passageway, a first and second load beam, a first and second scraper seal, and a first and second drive assembly. The inlet introduces the particulate material into the passageway and the outlet expels the particulate material from the passageway. The passageway is defined by a first belt assembly and a second belt assembly that are opposed to each other. The first and second load beams are positioned within the first belt assembly and the second belt assembly, respectively. The first scraper seal and a second scraper seal are positioned proximate the passageway and the outlet. The first drive assembly is positioned within an interior section of the first belt assembly and drives the first belt assembly and the second drive assembly is positioned within an interior section of the second belt assembly and drives the second belt assembly.
