摘要： A system includes a turbo pump to convert compressed gas into power, a storage tank to store the compressed gas, and a fire suppression control valve having a closed position in which the compressed gas is prevented from flowing to the cargo compartment and an open position in which the compressed gas is ported to the cargo compartment to suppress a fire. The system also includes a pump control valve having a closed position in which the compressed gas is prevented from flowing to the turbo pump and an open position in which the compressed gas is ported to the turbo pump to cause the turbo pump to convert the compressed gas into the power. The system also includes an OBIGGS to convert bleed air from a gas turbine engine into an inert gas to provide low rate discharge (LRD) fire suppression to the cargo compartment.

摘要： The present disclosure provides systems and methods for processing ammonia. The system may comprise one or more reactor modules configured to generate hydrogen from a source material comprising ammonia. The hydrogen generated by the one or more reactor modules may be used to provide additional heating of the reactor modules (e.g., via combustion of the hydrogen), or may be provided to one or more fuel cells for the generation of electrical energy.

摘要： A device for harvesting and storing triboelectric charge generated on an exterior surface of a moving vehicle is provided. It is characterised by comprising; a supercapacitor comprised of nano-carbon-containing electrodes; an ionic liquid electrolyte and at least one ion-permeable porous membrane; at least one first element exposed to aerodynamically-induced frictional forces acting thereon and on which the charge is caused to build up and connected to at least one of the electrodes of one polarity; at least one second element having a lower electrostatic potential than the charge-collecting element and connected to at least one of the electrodes of the other polarity; a voltage modification or impedance conversion circuit arranged between the first and/or second elements and the supercapacitor; means to connect the device to an operative component requiring electrical power and a controller for managing the performance of the device and switching between energy-harvesting and energy-utilisation modes. The device is especially use for deployment in the wing of an aircraft to utilised triboelectric charge generated thereon.

摘要： The present disclosure provides systems and methods for producing a hydrogen storage vessel that is lightweight. The hydrogen storage vessel may comprise an inner body and an outer body structured as concentric rings with a conic interface. The vessel may have four material layers, including a barrier layer, an insulation layer, a fiber knit, and an abrasion layer. The fiber knit may be braided to trap the hydrogen, as the barrier layer may not be completely impermeable. Additionally, the fiber braid may be clamped to the outer body, enabling pressure pushing on the inner body to wedge and seal the storage vessel.

摘要： An aircraft with the capability of taxiing with main engines off uses the energy stored in a mechanical flywheel to power a propulsor(s) providing taxiing thrust. The flywheel can store energy generated by the propulsor operating as a wind turbine and/or by a power turbine in fluid coupling with the exhaust of a gas turbine engine and/or an expansion turbine operating with bleed and/or APU air.

摘要： A high-speed vertical take-off and landing aircraft has a lifting structure, a first rotor with a first and second blade, a second rotor with a first and second blade, an auxiliary propulsion unit for providing forward thrust, and a control system for controlling the pitch of each of the rotor blades. The aircraft has a first, rotor-only, flight mode for hovering and low speed maneuvering. It also has a second flight mode where the rotors are held in at fixed azimuth angles and forward thrust is provided by the auxiliary propulsion unit. Three axis control is provided during the second flight mode by adjusting the attack angles of the fixed rotor blades. Between these two flight modes, there is an intermediate flight mode covering a fully controlled transition between the first two flight modes.
