SUPERSONIC EXHAUST NOZZLE FOR AIRCRAFT ENGINEPURPOSE: To control the temperature rise of the nozzle wall face in a throat portion by effectively cooling the throat portion of a nozzle being large in thermal load in a supersonic exhaust nozzle for an aircraft engine.SHIRAISHI HIROYUKI...
The aircraft exhaust engine nozzle system includes a fan nozzle to receive a fan flow from a fan disposed adjacent to an engine disposed above an airframe surface of the aircraft, a core nozzle disposed within the fan nozzle and receiving an engine core flow, and a pylon structure connected ...
An analysis of jet aircraft engine exhaust nozzle entrance profiles,accountability and effects The augmentor and exhaust nozzle are components that are very critical in an aircraft gas turbine engine. The high thrust/weigh ratio demanded by modern aircraft engine implies a need to have an augmentor ...
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...
气缸经历着连续的四冲程循环,这四个冲程分别称为进气(Intake),压缩(Compression),动力(Power)和排气(Exhaust)。 进气冲程:当气缸内的活塞向下运动腾出位置时,进气门打开,燃油空气混合物被吸入气缸燃烧室。 活塞到达气缸的底部时,进入压...

This invention relates to the cooling of aircraft gas turbine engine exhaust nozzles and more particularly to means for transferring cooling air to cooling air passages of pivotable flaps and seals in a variable throat area exhaust nozzle. 2. Description of Related Art Aircraft gas turbine eng...
The Ordinary convergent exhaust nozzle is a perfectly satisfactory and efficient device for converting pressure in the jet pipe into velocity, so long as the pressure ratio across it remains below about 2.0; or, put another way, so long as the velocity at exit from the nozzle is not theoretic...
Suppression system for a gas turbine engine A suppression system for a gas turbine engine uses a tapered exhaust manifold with a plurality of exhaust nozzles acting in conjunction with a plurality of mixing cells to produce cooling of an exhaust gas stream upon exit from an aircra... Robert ...
