    摘要: A fairing for protecting a payload from excessive acoustic energy is disclosed. The fairing can be used with a launch vehicle for launching payloads such as satellites or the like. The invention provides structure to surround a payload and absorbs acoustic energy so that the noise is suppressed to acceptable levels and the payload is not damaged. The fairing comprises a two dimensional honeycomb core having composite face sheets and load skins bonded to each side of the core. A water barrier is connected to the inner side of the fairing to prevent moisture from entering the payload area. The fairing may include an energy absorbing blanket connected to the inner side of the fairing to further suppress the energy generated by a launch vehicle.

    摘要: A propulsion system for aerospace vehicles employs dipole radiators in an interlayer space between outer and inner layers of the vehicle hull. Microwaves are applied, via a control console, to the radiators. The hull may be configured as sectors, and energy may be applied sector by sector to control levitation and propulsion. The outer hull layer can have a grooved inner surface, and may be formed of a titanium or beryllium alloy.

    摘要: A turbo-rocket thruster is disclosed in which the turbine compressor is used to intake and compress a gaseous fuel for combustion with a stored oxidizer injected into the compressed gaseous fuel stream. The compressor stage is driven by the turbine stage, which is driven by burning gaseous fuel passing across the turbine blades. The burned gases are then expanded through an exhaust nozzle and thereby ejected to produce reaction thrust.

    摘要: A rocket launching system employing ignition apparatus that is used with a small rocket to launch the rocket from a gun. The rocket is equipped with acoustic (pressure) and optical (thermal) sensors that detect a pressure pulse and light flash of a primer charge used to fire the gun. The simultaneous detection of the pressure pulse and the light flash by the sensors generates output signals that are used to complete an electrical circuit in an electronic ignition circuit that activates an igniter that ignites a rocket motor.

    摘要: An acceleration force isolator assembly for attaching a payload, such as a spacecraft or satellite, to a launch vehicle wherein axial acceleration forces on the payload are attenuated. The attachment includes an upper interface ring that is secured to the payload and a lower interface ring that is secured to the launch vehicle. Flexure of the upper interface ring provides axial compliance when axial acceleration forces are transmitted from the launch vehicle.

    摘要: A low-cost, liquid-propellant rocket launch vehicle having a central pod that carries an optional final-stage rocket engine cluster, and having additional engine clusters arranged in diametrically opposed pairs of clusters. The pairs of clusters are burned and separated in a staging sequence until the final stage is reached. In the presently preferred embodiment, there are three pairs of engine clusters arranged in a hexagonal configuration about the central pod and each engine cluster contains seven identical engines. The engines are made from light-weight, low-cost materials, without gimbals or other moving parts. Steering of the vehicle is effected by differential control of the engine thrusts of selected engines, using duty-cycle modulation of a plurality of on/off propellant supply valves and, additionally, control of other on/off valves controlling the supply of an inert cryogenic fluid to secondary injection ports on the engine. An onboard gas generator provides inert gas for fluid pressurization and preferably uses as its principal reactant the same material used as the cryogenic fluid. Navigation is effected with inexpensive onboard systems and the entire vehicle provides a dramatic reduction in cost in comparison with conventional launch vehicles.

    摘要: An apparatus and method for translating a spacecraft (102, 108) from an injection orbit (114) about a central body (100) to synchronous orbit (122) in a time efficient manner. The spacecraft (102, 108) includes propulsion thrusters (50) which are fired in predetermined timing sequences controlled by a controller (64) in relation to the apogee (118) and perigee (120) of the injection orbit (114) and successive transfer orbits (114). During transfer orbit, the spacecraft's inertial attitude is adjusted to track sun movement. The spacecraft is injected into a particular injection orbit that offsets moments created by tracking sun movement to maintain stable transfer orbits.
