Description

A kind of aircraft gas cylinder
Technical field
The present invention relates to a kind of aircraft gas cylinder.
Background technology
With the development of Aeronautics and Astronautics technology, the bearing capacity requirement to aircraft is gradually stepped up, it is necessary to which flying instrument is standby How bigger bearing space and bigger load-bearing weight, consider that reduction aircraft is weighed in itself while engine power is improved Amount, the weight of the accessory of aircraft, reduction aircraft in accessory occupancy volume will be improve aircraft carrying energy One main direction of studying of power.The general volume of gas cylinder used in conventional aircraft is larger, is relatively large in diameter, and use steel It is made, weight is also than larger, it is impossible to meet the requirement of course of new aircraft, particularly with narrow space, gas cylinder installing space For narrow aircraft, conventional cylinder can not be continuing with.
The content of the invention
Leptosomatic it is an object of the invention to provide a kind of narrow installing space that disclosure satisfy that new aircraft flies Row device gas cylinder.
To achieve the above object, aircraft of the invention is adopted the following technical scheme that with gas cylinder：
Technical scheme 1：Aircraft includes bottle with gas cylinder, and bottle has air inlet and gas outlet, the draw ratio model of the bottle Enclose is 6 ~ 20.
Technical scheme 2：On the basis of technical scheme 1, the material of the bottle is titanium alloy.
Technical scheme 3：On the basis of technical scheme 1 or 2, the bottle is made up of bottle head, bottle tail and cylindrical section, bottle head The two ends of cylindrical section are welded on using electro-beam welding process with bottle tail.
Technical scheme 4：On the basis of technical scheme 3, the air inlet and gas outlet are separately positioned on the two ends of bottle.
Technical scheme 5：On the basis of technical scheme 3, the cylindrical section is processed using the cold rolling moulding process of cylinder.
Technical scheme 6：On the basis of technical scheme 4, air inlet is arranged at a bottle tail, air inlet and is provided with intake valve, Safety valve and pressure gauge are additionally provided with bottle tail.
Technical scheme 7：On the basis of technical scheme 6, bottle tail is provided with the groove caved in, the intake valve, safety valve It is located at pressure gauge in groove.
Technical scheme 8：On the basis of technical scheme 6 or 7, gas outlet is located on bottle head, and main valve is provided with gas outlet, main Valve includes filter and check valve.
Technical scheme 9：On the basis of technical scheme 8, being provided with the main valve is used for and carry-on airway tube The screw thread of road interface connection.
The beneficial effects of the invention are as follows：The aircraft of the present invention includes gas cylinder with gas cylinder, because new aircraft has one Individual long and narrow installing space, the bottle of gas cylinder is in slender type, and draw ratio scope is 6 ~ 20, can be adapted to the long and narrow installing space, Do and targetedly designed the present invention be directed to the new installation requirement of new aircraft, the gas cylinder designed is in slender type, can Meet the harsh installation requirement of this kind of aircraft.
Further, bottle uses titanium alloy material, and titanium alloy has the advantages that specific strength is high, equality strength rank （1250MPa or so）Titanium alloy material proportion be only the 61.3% of steel, this means that is replaced with titanium alloy gas by traditional steel cylinder Bottle weight will mitigate nearly 40%, be especially suitable for using on Aeronautics and Astronautics aircraft, while weight is reduced, due to titanium alloy Intensity is high, and the pressure that can bear internal gas is larger, titanium alloy cylinder and common steel cylinder for equal receiving volume, titanium alloy Gas cylinder can accommodate more gases.
Further, bottle is made up of bottle head, cylindrical section, the part of bottle tail three, is molded using electron beam welding, weld seam hot shadow Sound area is small, weld seam is small, Forming Quality is high.
Further, after bottle is arranged in the long and narrow installing space of aircraft, only two ends are spilt, in order to meet Operation is inflated on the premise of not dismantling gas cylinder simultaneously again without interference with its normal outlet, therefore air inlet and gas outlet are divided Bottle two ends are not arranged on, to facilitate online inflation.
Further, using cold rolling shaping, it, which is developed, avoids that conventional elongated titanium tube of thin wall machining difficulty is big, material The problems such as utilization rate is low, can not obtain fine and close metallographic structure, material comprehensive mechanical performance is poor, while also solving traditional high-strength titanium The elongated thin-walled drawn and rolled tube dimensional accuracy of alloy is low（Evenness of wall thickness, linearity, circularity）, the problem such as surface quality difference；Using Pipe direct cold rolling, is rolled relative to conventional panels and welding manner has weldless advantage, significantly improves structural strength；Adopt Above-mentioned technique is used, product cost is low, pressure-bearing is high, good combination property.
Further, the discouraged function of superpressure can be achieved in the setting of safety valve, and the real-time of pressure can be achieved in manometric setting Monitoring, it is that operator checks and operated for convenience that three, which is arranged on a bottle tail,.
Further, the setting of filter can be filtered to gas on main valve so that the gas exported from gas cylinder is purer Only.
Further, the setting of screw thread not only facilitates the connection with gas-guide pipeline interface on main valve, and with to gas cylinder The booster action of axial restraint.
