Abstract
The present invention relates to aircraft additional device field of structural design, specifically, relate to a kind of agriculture boat aircraft hopper.A kind of agriculture boat aircraft hopper, comprise casing, described casing adopts frp sandwich construction, and the ectonexine of described frp sandwich construction is glass woven fabric laying, and interlayer is plastic foam sandwich structured layer.The casing of agriculture boat aircraft hopper of the present invention adopts frp sandwich construction, and can bear elevated pressures, quality is light, and acid-alkali-corrosive-resisting, maintenance cost is low, long service life.
Description
Technical field
The present invention relates to aircraft additional device field of structural design, specifically, relate to a kind of agriculture boat aircraft hopper.
Background technology
Along with the popularization day by day of General Aviation agricultural aircraft aviation operation, one had both met agriculture boat spraying operation demand, and the agriculture boat hopper meeting again aircraft agricultural equipment system features becomes agriculture boat equipment research emphasis.Domestic existing agriculture boat hopper has all-metal and metallic framework two kinds, and is all installed in aircraft cabin, not only heavier-weight, also additionally occupies carry-on finite space in a large number.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality need, a kind of agriculture boat aircraft hopper is provided.
In order to realize object of the present invention, the technical solution used in the present invention is:
A kind of agriculture boat aircraft hopper, comprise casing, described casing adopts frp sandwich construction, and the ectonexine of described frp sandwich construction is glass woven fabric laying, and interlayer is plastic foam sandwich structured layer.
Described casing top is upper wall, and described upper wall is provided with top-feed lid, and described casing rear portion is provided with rear portion filling opening.
The shape of described casing upper wall and aircraft configuration shape face match and substitute a part for aircaft configuration covering.
Also be provided with breather pipe, one end of described breather pipe is communicated with box house, and the other end is communicated with air.
Be provided with anti-sloshing baffles in described casing, described anti-sloshing baffles is the diaphragm structure of horizontally set, and the wooden partition of dividing plate is covered with honeycomb hole.
Beneficial effect of the present invention is:
1. casing adopts frp sandwich construction, can bear elevated pressures, and quality is light, acid-alkali-corrosive-resisting, and maintenance cost is low, long service life;
2. the design of two charge doors realizes aircraft and not to stop dosing;
3. upper wall presses flight vehicle aerodynamic configuration design, replaces a part for aircraft skin, reduces aircraft resistance and structural weight;
4. built-in breather pipe, prevents from producing negative pressure in hopper;
5. liquid, solid (particulate matter) are general, can integral disassembly, assembly, and version is simple, opening clear, and clean and maintenance is convenient
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment: see Fig. 1.
A kind of agriculture boat aircraft hopper, comprise casing 2, described casing adopts frp sandwich construction, and the ectonexine of described frp sandwich construction is glass woven fabric laying 7, and interlayer is plastic foam sandwich structured layer 8.This version intensity is high, and good rigidly, is applicable to large-size components, glass cloth material, the number of plies, and the choose reasonable of foamed plastic sandwich material, density, thickness and glue can meet the actual demand of agriculture aircraft aviation operation hopper.This design can meet the requirements such as aviation liquid container pressure test, and the hopper of all-metal or metal framework structure can reduce the structural weight of 50-100% relatively.Glass-felt plastic non-metallic material has good decay resistance, long service life, is applicable to the operating needs that the various agricultural chemicals of agriculture boat operation etc. spray carrier.The various repairing characteristics of glass-reinforced plastic material are applicable to this glass-felt plastic agriculture boat hopper, greatly reduce maintenance time and cost, indirectly improve aircraft operation benefit.
Casing top is upper wall 10, and described upper wall 10 is provided with top-feed lid 11, and described casing 2 rear portion is provided with rear portion filling opening 4.Top-feed lid 11 can be hopper and provides liquid and solid (particulate matter) loading channel, and rear portion filling opening 4 makes liquid feeding passage away from properller, can implement aircraft floor not stop liquid feeding at aft.
The shape of described casing upper wall 10 and aircraft configuration shape face match and substitute a part for aircaft configuration covering.Agriculture boat aircraft hopper is the airborne tankage of large scale, reduces aero-structure weight, upper wall 10 is designed to aircraft configuration shape face, substitutes aircaft configuration covering for the finite space on Appropriate application aircraft, is a kind of rationally practicable ways efficiently.
Also be provided with breather pipe 1, one end of described breather pipe 1 is communicated with casing 2 inside, and the other end is communicated with air, prevent agriculture navigate operation and jury launch time hopper in negative pressure generation.
Be provided with anti-sloshing baffles 12 in described casing, described anti-sloshing baffles 12 is the diaphragm structure of horizontally set, and the wooden partition of dividing plate is covered with honeycomb hole, meets the requirement of large-scale liquid container to liquid anti-shake.Box house adopts large radian corner, and the design of each bevel angle meets the requirement of object stacking angle of repose, makes can not produce the residual phenomenas such as bridging during hopper loading solid material.
Observation window 3 is also provided with on rear portion filling opening 4 side, can Real Time Observation control reinforced according to the situation of material in casing.Be furnished with rustproof aluminum alloy lower flange 6 bottom hopper, for hopper jury launch device or other equipment connections.Hopper by strengthening the bolt assembly at pad 9,5 place before and after dismounting, to hopper integral disassembly, assembly, can be convenient to casing and safeguard.
The invention of glass-felt plastic agriculture of the present invention boat medicine-chest, improves the system effectiveness of aircraft agricultural equipment, saves agriculture boat aircraft operation cost, and improving agriculture boat operational benefit, also to fill up domestic correlation technique blank.
