Background technique
The main function of the aerofoil is to generate lift, overcomes gravity to realize the maneuvering flight of guided missile, and guarantee good
Maneuverability and stability.Modern strategic demand is answered, in order to fight the scouting and identification of radar and other electronic equipments, is improved hidden
Property enhancing survival ability to reach anti-purpose of dashing forward need to generally use stealth technology on board the aircraft.The aerofoil is meeting stealthy function
Under the premise of energy demand, also by construction weight restrict；Meanwhile also needing have the strong rigidity met under various flight operating conditions
Demand.
What usual aerofoil was made of basic building blocks such as spar, stringer, rib, foam insert and coverings: the function of spar
It is subject to the moment of flexure and shearing of the wing；The function of rib is to constitute and keep defined wing.Aerofoil load path are as follows: local air
The torque that power is formed is transmitted to covering by way of shearing flow, then passes to spar web, and then covering, spar, purlin by covering
Item, rib form combination stressed.Overall skeleton is formed by stringer, rib, spar, foam insert etc., to improve aerofoil rigidity.
Stealth material is divided into coating type and structural type two major classes by technique and bearing capacity.Coating type refer to aircraft or
Piece surface, which coats one layer, has the coating for inhaling wave energy, and applicability is most wide.However, coating stealth material is there are many drawbacks,
The combination of coating and panel is limited by various factors, and fastness is poor, easy to fall off；Secondly, coating layer thickness is difficult to control, Bao Zewu
Method reaches ideal wave-absorbing effect, and too thick and intensity is too low, and it is too big to increase weight, therefore coating is stealthy that there are significant limitations.
Summary of the invention
Goal of the invention: the wide material of integrated application applicability makes missile wing meet the stealthy and difunctional demand of load, and
Reach weight loss effect.
Inventive technique scheme: a kind of stealthy/force-bearing type structure aerofoil, the stealthy/force-bearing type structure aerofoil overall skeleton

Filling member III 8；Overall skeleton outer mold surface coats wave transparent covering 6, leading edge cladding leading edge radome fairing 1 forms monoblock type airfoil structure；
It is characterized in that, being glued wave absorbing patch, composite material master after overall skeleton composite material girder 12 and composite material on the outside of wall 13
Beam 12 increases diamond shape cushion block 11 by aerofoil leading edge position.
The covering 6, leading edge radome fairing 1 and rear cushion block 7 use wave-penetrating composite material.
The electromagnetic wave transparent material is F.BG-6-01.
The covering 6 and 1 design thickness of leading edge radome fairing are 1mm.
The covering 6 uses J-135 room temperature glue sticking with leading edge radome fairing 1.
The filling member I 2, filling member II 3, III 8 material of filling member are to inhale wave foam.
The suction wave foam selects Polymethacrylimide (PMI) to mix graphene suction wave cystosepiment, passes through machine plus side
Formula guarantees its shape.
5 outer surface of aerofoil fixed-wing coats stealth material.
Wall 13 and diamond shape cushion block 11 select NY9200GA/HF10A after the composite material girder 12, composite material girder
Carbon fibre composite distinguishes solidified forming using autoclave.
The wave absorbing patch 10 is with a thickness of 0.8mm.
Advantageous effect of the invention: the present invention respectively forms the architectural characteristic of component, the glue on the outside of girder and rear wall for aerofoil
Wave absorbing patch is connect, for eliminating reflection of the wall to electromagnetic wave after composite material girder and composite material；It is leaned in composite material girder
Aerofoil leading edge position increases diamond shape cushion block, to weaken the remaining electromagnetic wave of scattering；Filling member, which uses, inhales wave energy foamed material,
For absorbing the electromagnetic wave for penetrating wave transparent covering.Meanwhile it integrated application wave-penetrating composite material, inhaling wave foamed material, inhaling wave patch
Piece, Coating Stealth Material and main load composite material meet the stealthy and difunctional demand of load, and the more conventional coating type wing
Face weight loss effect is obvious.
