Generator discharges smog, and whether observe outside air-tight cabin has smog leakage, and the place that smog leakage be present is marked.
Preferably, when the pressure of aircraft air-tight cabin to be measured reaches test pressure value, then aerosol producer is controlled to discharge cigarette
Mist.
Preferably, the smog of the aerosol producer release is with coloured smog.
Preferably, the airtight inspection method of aircraft air-tight cabin further checks comprising start, specifically, being filled to air-tight cabin
After the completion of pressure, engine is opened, and maintain certain time.
Preferably, aerosol producer release smog is controlled first, makes to be full of smog in air-tight cabin, then air-tight cabin is carried out
Whether pressurising, observing outside air-tight cabin has smog leakage.
Preferably, the smog of the aerosol producer release is with coloured smog.
Preferably, pressure sensor is set in aircraft air-tight cabin to be detected, monitored in real time using pressure sensor airtight
Pressure in cabin；Aerosol producer release smog is controlled, the atmospheric pressure value recorded after smog now in air-tight cabin is full of in air-tight cabin,
And check outside air-tight cabin whether there is smog leakage；Then pressurising is carried out to air-tight cabin, and by pressure stability in design pressure value.
Preferably, the airtight inspection method of aircraft air-tight cabin further checks comprising start, specifically, being filled to air-tight cabin
After the completion of pressure, engine is opened, and maintain certain time.
The beneficial effects of the present invention are：
The airtight inspection method clear principle of aircraft air-tight cabin of the present invention, it is simple to operate, it can intuitively find all gas leakage
Source, avoid passing through sense organ and search leaking source, save human cost, improve efficiency.
Embodiment
A kind of airtight inspection method of aircraft air-tight cabin, aerosol producer is placed in aircraft air-tight cabin to be measured；Fly to be measured
Machine air-tight cabin carries out pressurising, and controls aerosol producer to discharge smog, and whether have smog leakage, to existing if observing outside air-tight cabin
The place of smog leakage is marked.
In the present embodiment, so that fuselage is from the airtight inspection of air-tight cabin as an example, when the pressure of aircraft air-tight cabin to be measured reaches examination
When testing pressure value, then aerosol producer is controlled to discharge smog.It is understood that the test pressure value can set it is multiple,
Gradually increase the atmospheric pressure value in fuselage air-tight cabin from small to large, to check the air-tightness under different pressures state, accurate perception gas
The atmospheric pressure value that close cabin can bear everywhere.
It is understood that when doing the airtight inspection of fuselage air-tight cabin, aerosol producer can be arranged at hatch door, and its is excellent
Point is, due to sealing problem at hatch door be present, if sealing is bad, can pinpoint the problems in time.
In the present embodiment, the smog of the aerosol producer release is with coloured smog.It the advantage is that, it is convenient
Observe and record the place of gas leakage.It is understood that the coloured smog of band should select color brighter relative to air
Aobvious color, for example, in an alternative embodiment, the color of aerosol producer release is red；In another alternative embodiment
In, the smog color of aerosol producer release is black.
In the present embodiment, the airtight inspection method of aircraft air-tight cabin further checks comprising start, specifically, to gas
After the completion of close cabin pressurising, engine is opened, and maintain certain time.It the advantage is that, after opening engine, due to engine
Vibration, fuselage can be influenceed by certain, and experimental enviroment is more nearly actual working environment, be advantageous to improve experiment accuracy.
It is understood that in the airtight inspection of specifically progress aircraft air-tight cabin, the unlatching of aerosol producer and air-tight cabin
The sequencing of pressurising can also be set according to actual conditions.For example, in an alternative embodiment, smog hair is controlled first
Raw device release smog, make to be full of smog in air-tight cabin, pressurising then is carried out to air-tight cabin, whether observe outside air-tight cabin has smog
Leakage.It the advantage is that, can be with the sealing of Real Time Observation air-tight cabin, due to being filled with cigarette in air-tight cabin in Plenum Process
Mist, can be at any time it was observed that the leakage of air-tight cabin, inspection method be more straight when the pressurising value in air-tight cabin reaches certain value
Connect, it is simple to operate.
It is understood that in above-mentioned alternative (first opening aerosol producer makes to be full of smog in air-tight cabin),
The smog of the aerosol producer release is with coloured smog.It is understood that the coloured smog of band should select
Color is selected relative to the obvious color of air, for example, in an alternative embodiment, the color of aerosol producer release is red
Color；In another alternative embodiment, the smog color of aerosol producer release is black.
It is understood that in above-mentioned alternative (first opening aerosol producer makes to be full of smog in air-tight cabin),
Pressure sensor is set in aircraft air-tight cabin to be detected, monitors the pressure in air-tight cabin in real time using pressure sensor；Control
Aerosol producer discharges smog, and air-tight cabin is interior full of the atmospheric pressure value recorded after smog now in air-tight cabin, and checks outside air-tight cabin
Whether portion has smog leakage；Then pressurising is carried out to air-tight cabin, and by pressure stability in design pressure value.It the advantage is that, energy
Enough accurate control actual atmospheric pressure values born of air-tight cabin, determine atmospheric pressure value during pressure release.
It is understood that in above-mentioned alternative (first opening aerosol producer makes to be full of smog in air-tight cabin),
The airtight inspection method of aircraft air-tight cabin further checks comprising start, specifically, after the completion of to air-tight cabin pressurising, opens hair
Motivation, and maintain certain time.It the advantage is that, after opening engine, due to the vibration of engine, fuselage can be by certain
Influence, experimental enviroment is more nearly actual working environment, is advantageous to improve experiment accuracy.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
The present invention is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the essence of various embodiments of the present invention technical scheme
God and scope.
