Abstract
The invention discloses an aircraft smoke plume system, which comprises a supercharging and conveying device, a control device, a smoke plume nacelle and a nozzle (7), and is characterized by also comprising a blowing device, wherein the blowing device is communicated with the nozzle and consists of a gas source (1), a gas decompressing device (2), an electromagnetic valve (3) and a one-way valve (4); due to the increase of the blowing device, a conduit (6) and the nozzle (7) become clean after a large amount of smoke plume agent which is detained in the conduit (6) and the nozzle (7) is blown off in a smoke plume process, so that the maintenance workload of the ground service of the smoke plume system is reduced, meanwhile, the corrosion harm is also eliminated; and next, after blowing is finished, air is isolated from the conduit (6) by an inert gas, so that a small amount of smoke plume agent retained in the conduit (6) is not mixed with the air to explode, and the safety performance in use of the smoke plume system is improved. In addition, the ambient temperature of the nozzle (7) exceeds 1,700 DEG C, and the inert gas flows by the nozzle (7) to exert a cooling effect, so that the end part of the nozzle (7) is prevented from dry burning, and the service life of the nozzle (7) is prolonged.
Description
Technical field
The present invention relates to a kind of aircraft and draw the cigarette system, what relate in particular to a kind of demonstrator draws the cigarette system.
Background technology
The cigarette system of drawing of specialty demonstrator can make aircraft draw the fumicants atomizing to form the column of smoke liquid awing.General performance machine draw the cigarette system; Mainly by supercharging feedway, control setup, draw cigarette gondola, nozzle etc. to form; The supercharging feedway can be high pressure gas or oil pump, and liquid is drawn the fumicants supercharging after control setup is delivered to nozzle, is pressed commander's ejection of control setup by nozzle; Supercharging feedway, control setup are placed on by the pipeline connection and draw in the cigarette gondola, and nozzle is installed in the engine tail nozzle place.After finishing to draw cigarette, stop to supply with the power supply that high pressure gas perhaps cut off oil pump, at this moment; Have a large amount of liquid and draw fumicants to be trapped in pipeline and to draw in the cigarette nozzle, the end of nozzle is in the engine tail nozzle, and ambient temperature is high; Liquid draws explosive materials such as containing toluene in the fumicants; Behind air-blending, form miscellaneous gas and blast easily, this will cause great harm to the safety of drawing the cigarette system.Because liquid draws fumicants that the parts that draw the cigarette system are corrosive, need cleaning pipe and draw the cigarette nozzle after performance finishes, draw the maintenance of cigarette system very big.
Summary of the invention
The technical matters that the present invention will solve is to provide a kind of aircraft safe and reliable, that maintenance is little to draw the cigarette system.
For solving the problems of the technologies described above; A kind of aircraft of the present invention draws the cigarette system to comprise supercharging feedway, control setup, draws cigarette gondola, nozzle; The supercharging feedway draws the fumicants supercharging after control setup is delivered to nozzle with liquid; By commander's ejection that nozzle is pressed control setup, supercharging feedway, control setup are placed on by the pipeline connection and draw in the cigarette gondola, and nozzle is installed in the engine tail nozzle place; Described supercharging feedway is that the described control setup of high-pressure air source or oil pump is to draw the cigarette control cock; It is characterized in that: also comprise blowning installation, described blowning installation is communicated with nozzle, is made up of source of the gas, air pressure reducer, electromagnetic valve, check valve; Source of the gas output high pressure gas after the air pressure reducer decompression successively through electromagnetic valve, check valve be connected into conduit near drawing cigarette control cock one end; Described air pressure reducer is the gas pressure reducer that includes safety valve, and described source of the gas is the high-pressure gas bottle that unreactable gas is housed, and described source of the gas, air pressure reducer, electromagnetic valve, check valve are connected by metal tubes.
The present invention has following good effect than prior art.A kind of aircraft of the present invention draws the cigarette system owing to increased blowning installation, draw be trapped in a large number in the cigarette process conduit and nozzle draw fumicants to be blown down after, conduit and the nozzle cleaning that becomes has reduced the ground service maintenance that draws the cigarette system, has also eliminated corrosion harmfulness simultaneously.Secondly after the completion of blowing, unreactable gas is isolated air from conduit, the fumicants that draws on a small quantity that is trapped in the conduit is not blasted with air-blending, has improved the safety performance that draws the cigarette system to use.The ambient temperature of nozzle surpasses 1700 ℃ in addition, and the unreactable gas nozzle of flowing through has played cooling effect, the end of nozzle is avoided " dry combustion method ", has prolonged the service life of nozzle.
Description of drawings
Fig. 1 is that a kind of aircraft of the present invention draws the scheme drawing of cigarette system.
The specific embodiment
Fig. 1 is that a kind of aircraft of the present invention draws the scheme drawing of cigarette system.Aircraft draws the cigarette system to comprise supercharging feedway, control setup, draws the cigarette gondola, nozzle 7; Described supercharging feedway draws the fumicants supercharging after control setup is delivered to nozzle 7 with liquid; Press commander's ejection of control setup by nozzle 7; Supercharging feedway, control setup are placed on by the pipeline connection and draw in the cigarette gondola; Described supercharging feedway is that the described control setup of high-pressure air source or oil pump is to draw cigarette control cock 5, it is characterized in that: also comprise blowning installation, described blowning installation is communicated with nozzle 7; Form by source of the gas 1, air pressure reducer 2, electromagnetic valve 3, check valve 4, source of the gas 1 output high pressure gas after air pressure reducer 2 decompressions successively through electromagnetic valve 3, check valve 4 be connected into conduit 6 near drawing cigarette control cock 5 one ends.
At first use high-pressure gas bottle splendid attire compressed inert such as nitrogen as source of the gas 1; Described air pressure reducer 2 is the gas pressure reducers that include safety valve; When cut-back pressure is too high, can exit, play a protective role; Air pressure reducer 2 with the high pressure air reducing of source of the gas 1 is and the low-pressure gas that draws the cigarette system matches; Whether electromagnetic valve 3 may command conductive pipe 6 supplying nitrogens, and check valve 4 can prevent to draw the fumicants of cigarette system to get into electromagnetic valve 3 and high-pressure gas bottle, and described source of the gas 1, air pressure reducer 2, electromagnetic valve 3, check valve 4 are connected by metal tubes.Blowning installation be connected into conduit 6 near drawing cigarette control cock 5 one ends.
After demonstrator draws cigarette to stop, opening electromagnetic valve 3, the liquid that the unreactable gas of low pressure will be trapped in conduit 6 and nozzle 7 draws fumicants to blow down, and has exempted ground service cleaning pipe 6 and nozzle 7 when ground maintenance, has reduced the maintenance that draws the cigarette system; When driving engine is in afterburning state, open electromagnetic valve, the low-pressure nitrogen nozzle 7 of flowing through is nozzle 7 coolings, both can prolong the service life of nozzle 7, can improve the environment for use temperature of nozzle 7 again; After inert nitrogen gas was filled full conduit 6, the small amount of liquid that still is trapped in the conduit 6 drew fumicants can not blast with air-blending.
