PURPOSE: To control exhaust currents properly, and improve combustion efficiency of an engine by forming a pair of walls facing each other in an exhaust nozzle of segments separated in the length direction, and composing each segment to be capable of advancing and retracting relative to a center...
JET ENGINE EXHAUST NOZZLE
Fairly small surface area to keep cool, and no turbine in hot exhaust stream. Very high-temperature combustion and high expansion-ratio nozzle gives very high efficiency, at very high speeds.运动部件非常少。从0马赫到25+马赫;在非常高的速度下(>5马赫左右)效率很高。推重比超过100。没有复杂的进气口...
A variable area two-stage ejection nozzle exhaust system for a turbojet engine having an afterburner. wherein, a primary nozzle has spherical segments contained within a spherical shell housing which spherical segments are pivotally adjustable in response to augmented and non-augmented engine ...

The hot exhaust gases exit the engine through a tapering exhaust nozzle. Just as water squeezed through a narrow pipe accelerates dramatically into a fast jet (think of what happens in a water pistol), the tapering design of the exhaust nozzle helps to accelerate the gases to a speed of ove...
This paper deals with an aircraft jet-engine exhaust nozzle controller, based on a mixed constructive scheme: a hydraulic actuator and a turbine pressure ratio sensor as pneumatic command block. The pressure sensor works as pressure ratio transducer with a pressure feedback, represented by a micro...
