    摘要: A rocket nozzle having an axial double bell shape. The nozzle includes a first bell shape, a second bell shape and an inflection point where the first bell shape and the second bell shape meet. The inflection point is located between a location at the area ratio &egr;=10 and a location at 0.85×&egr;max of the nozzle, where &egr; is the narrowest cross-sectional area of the nozzle. The first bell shape and the second bell shape both have a contour line having an outwardly directed curvature of between 2 and 7 at the inflection point.

    摘要: An aircraft power plant for vertical take-off and landing comprises a jet propulsion unit having an air inlet and an exhaust outlet and incorporating a combustion chamber, a high pressure compressor for supplying air from the air inlet to the combustion chamber, a fuel inlet for supplying fuel to the combustion chamber, and a turbine coupled to drive the compressor and arranged to be driven by the exhaust gases passing from the combustion chamber to the exhaust outlet. Swivelling front nozzles are provided for selectively directing a proportion of air from a fan arrangement downwardly in front of the propulsion unit and swivelling rear nozzles are provided for selectively directing at least a proportion of the exhaust gases from the exhaust outlet downwardly to the rear of the propulsion unit, in order to effect lift on take-off or landing. The fan arrangement comprises a first fan for supplying air to the front nozzles and a second fan, positioned rearwardly of the first fan, for supplying air to the air inlet of the propulsion unit, as well as a shaft having a length which is chosen to position the front nozzles sufficiently far forward to produce the required moment about the aircraft center of gravity. Such an arrangement provides a highly efficient power plant which can be accommodated within a narrow cross-section, and which can be implemented without requiring gearboxes, clutches or hot ducts.

    摘要: A tailpipe for a gas turbine engine has a cylindrical portion and lobed portion. The lobed portion extends a length X and has a plurality of circumferentially disposed peaks and valleys. Over at least the first 30 percent of length X, the radius of the each valley is greater than the radius of each peak and is greater than 10% of the equivalent diameter DE. Also, the effective flow area at the end of the lobed portion is greater that the effective flow area at its beginning. The cylindrical portion includes a straight portion and a canted portion.

    摘要: Mixing of a subsonic exhaust plume from a nozzle is induced and enhanced, and shaping of the plume is controlled, by periodic pulsed jets of fluid injected into the plume from two or more locations spaced circumferentially about the plume. The jets are pulsed out of phase relative to one another. An active flow control apparatus includes at least first and second pulsed jet nozzles circumferentially spaced apart about the exhaust plume near an exit plane of the exhaust nozzle, and a pulse generator operable to supply periodic pulses of fluid to each of the pulsed jet nozzles such that the pulses to each nozzle are out of phase relative to the pulses to the other nozzle or nozzles.

    摘要: Plugs for protecting internal spaces of rocket combustion chambers against moisture, dust, and other environmental factors. Each plug includes a central rod with a bracket fastened to it. The plug also includes a sleeve with radially extending structural ribs. Spring-loaded cams with rollers are securely hinged at the ends of the ribs. In addition, a spring-loaded limiter and a valve are mounted on the central rod so that they can possibly move relative to the central rod. The limiter includes a sleeve and a conical shell that are connected by rod ties. The valve includes a metal stamped conical plate that forms a gas-tight fit with the rod. A sealing ring of elastic material is positioned on a peripheral part of the plate. The set of spring-loaded cams and the limiter secure the self-mounting plug in a working position and make the valve operation independent of the operation of other plug components.

    摘要: A lateral-thrust control device for a four-quadrant final-phase guidance control of a missile having lateral-thrust nozzles (10) communicating with a solid-fuel gas generator (13). Each of the nozzles has a valve member (22, 38), whose open and closed states are controlled by a common actuator (12, 30) which is rotatable and axially displaceable to select one nozzle to be supplied with gas from the gas generator while the other nozzles are closed according to the required flight mode. The actuator is configured such that each of the lateral-thrust nozzles (20) can be individually controlled to be active or inactive, intermittently, and independently of one another. In one embodiment, the actuator is a cylindrical piston and in another is a conical member.
