摘要: A method of thrust vectoring a missile utilizing jet tabs is presented. Jet tabs are used to create lateral control moments on a missile by rotating tabs into the rocket exhaust plume and changing the thrust deflection angle. The method includes simultaneously rolling the missile during the thrust vector maneuver in order to reduce the maximum tab exposure to the rocket plume. The method enables aggressive pitchover maneuvers while reducing the risk of tab failure due to excessive exposure.

摘要: A turbine pump assembly has a turbine, a centrifugal pump, a passive electrical speed control system, and a pneumatic circuit breaker. The pneumatic circuit breaker has a plurality of elements that are configured to move to a position blocking an outlet duct of the turbine when a flow velocity exceeds a predetermined threshold. A rocket thrust vector control system is also disclosed.

摘要: A thrust nozzle, in particular thrust nozzle for a rocket engine, with a convergent wall section, a throat section and a divergent wall section. The divergent wall section has a first region adjacent to the throat section, the wall contour of which region corresponds to a truncated ideal nozzle, and the divergent wall section has a second region facing away from the throat section, which region has a wall contour deviating from the first region.

摘要: A method and concept for employing a T-sin-alpha kill vehicle with energy flexibility is disclosed. The energy flexibility method applies divert pulses at multiple phases of the kill vehicle flight time and allows for range extension to increase the kill vehicle coverage of targets outside the normal reach, reaction to target updates, removal of navigation error, and homing divert to intercept the target. Each of these capabilities is essential to the successful intercept of exo-atmospheric ballistic targets in their midcourse phase of flight. A flight vehicle includes a main body, a number of attitude control mechanisms, a control unit, a divert system, a sensor unit, and an attitude control system. The divert system provides acceleration of the flight vehicle in a desired direction. The sensor unit tracks a target along a line of sight (LOS) of the sensor unit. The attitude control system maintains an orientation of the main body.

摘要: A variable geometry exhaust nozzle arrangement includes a plurality of hingable exhaust petals defining a perimeter of an exhaust duct and an annular ring slidably engagable against a radially outer surface of each petal. The annular ring is coupled to a plurality of circumferentially spaced actuator arrangements, each including first and second circumferentially spaced parallel actuator arms pivotably coupled to the annular ring at a first end and to a slide arrangement at a second end. Each slide arrangement is mounted for linear sliding movement relative to the annular ring, such that sliding movement of each slide arrangement causes pivoting of the first and second actuator arms to thereby translate the annular ring in one or both of a longitudinal direction and a lateral direction.

摘要: A satellite has thrusters that are integral parts of its frame. The frame defines cavities therein where thrusters are located. The thrusters may include an electrically-operated propellant and electrodes to activate combustion in the electrically-operated propellant. The frame may be additively manufactured, and the propellant and/or the electrodes may also be additively manufactured, with the frame and the propellant and/or the electrodes also being manufactured in a single process. In addition the thrusters may have nozzle portions through which combustion gases exit the thrusters. The thrusters may be located at corners and/or along edges of the frame, and may be used to accomplish any of a variety of maneuvers for the satellite. The satellite may be a small satellite, such as a CubeSat satellite, for instance having a volume of about 1 liter, and a mass of no more than about 1.33 kg.

摘要: A turbine pump assembly has a turbine, a centrifugal pump, and a passive electrical speed control system. The turbine has a peak efficiency at a first speed that is lower than a second speed at which the centrifugal pump is operating at a peak power requirement. A rocket thrust vector control system is also disclosed.

摘要: Attitude and/or attitude rate of a vehicle may be controlled using jet paddles and/or movable masses. Thrust direction generally may also be controlled using jet paddles. The jet paddles may be moved into and/or sufficiently close to the exhaust flow, and out of the exhaust flow, to change the thrust direction. Movable masses may also be used in addition to, or in lieu of, jet paddles. Movement of the movable masses alters a center-of-mass of the vehicle, generating torque that changes vehicle attitude.
