Description

A kind of Composite material elevator trailing edge bar
Technical field
The utility model relates to aircraft control surface structure-design technique field, in particular to a kind of Composite material elevator trailing edge bar.
Background technology
Trailing edge bar is arranged at elevating rudder afterbody, and Main Function connects covering, lower covering on elevating rudder, to improve elevating rudder integral structure rigidity and to maintain elevating rudder trailing edge aerodynamic configuration.Because civil aircraft elevating rudder afterbody aerodynamic configuration height is general lower, therefore elevating rudder tail side-strip structure mostly is elongate configuration, highly less, and cross sectional shape is complicated, opens up to accessory size variation in thickness large.
In prior art, elevating rudder trailing edge bar mainly adopts aluminum alloy manufactured by fine limit work or customize section bar manufacture, on the one hand the heavier-weight of part own, and has certain influence to controlsurface balancing of mass, and then affects aircraft handling efficiency; On the other hand in order to ensure trailing edge bar curved profile, dimensional accuracy and surface quality, having to carry out fine limit work to the surface of trailing edge bar, thus affecting the productive costs of part.Therefore, the problem needing now solution badly is a kind of elevating rudder trailing edge bar of design, can imitate and alleviate structural weight, raising structure efficiency and driving efficiency.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of simple and reasonable, Composite material elevator trailing edge bar of reducing part quality and manufacturing cost, raising aircaft configuration efficiency.
The purpose of this utility model is achieved through the following technical solutions: a kind of Composite material elevator trailing edge bar, comprises trailing edge bar body, and trailing edge bar body comprises foam core, ply wood, and ply wood is around foam core paving curing molding.
Preferably, foam core is connected into trailing edge bar body by resin and ply wood.
In above-mentioned either a program preferably, trailing edge bar body is integral type structure.
The beneficial effect of Composite material elevator trailing edge bar provided by the utility model is, alleviates the weight of trailing edge bar, thus reduces elevating rudder integral structure weight, be convenient to the balancing of mass of elevating rudder, improve structure efficiency and the driving efficiency of aircraft, device stability improves, safe and reliable.

Reference numeral:
Covering under 1-trailing edge bar body, 2-foam core, 3-ply wood, the upper covering of 4-, 5-.
Detailed description of the invention
In order to understand the Composite material elevator trailing edge bar according to the utility model scheme better, be further elaborated explanation below in conjunction with the preferred embodiment of accompanying drawing to Composite material elevator trailing edge bar of the present utility model.
As Figure 1-3, the Composite material elevator trailing edge bar that the utility model provides, comprises trailing edge bar body 1, and trailing edge bar body 1 comprises foam core 2, ply wood 3, and ply wood 3 is around foam core 2 paving curing molding.Foam core 2 is connected into trailing edge bar body 1 by resin and described ply wood 3.Trailing edge bar body 1 is integral type structure.
In prior art, elevating rudder trailing edge bar mainly adopts aluminum alloy manufactured by fine limit work or customize section bar manufacture, adopts the elevating rudder trailing edge bar sole mass of this material manufacture heavier and the driving efficiency of the aircraft that affects on the balance of controlsurface quality, affect.In addition, in order to ensure trailing edge bar curved profile, dimensional accuracy and surface quality, having to carry out fine limit work to the surface of trailing edge bar, thus affecting the productive costs of part.The Composite material elevator trailing edge strip adoption composite material that the utility model provides makes, and adopts the molded method of vacuum assisted resin transfer membrane shaping, greatly reduces hot pressing and fills with shaping manufacturing cost.
In concrete use procedure, corresponding trailing edge bar moulds of industrial equipment are produced according to the theoretical space between covering on elevating rudder 4, lower covering 5, the Composite material elevator trailing edge strip adoption composite material foam core sandwich structure that the utility model provides, moulds of industrial equipment are adopted to carry out paving to ply wood 3 around foam core 2, obtained trailing edge bar preformed parts, are coated with resin between ply wood 3 and foam core 2.Preformed parts, by frock preheating, during this period, are vacuum seal, vacuum between ply wood 3 and foam core 2.Resin melting in frock warm, ply wood 3 and foam core are linked together by resin, then solidification, the demoulding, carry out machine up, repairing to Composite material elevator trailing edge bar profiled member, makes the Composite material elevator trailing edge bar body 1 being formed and meet usage condition.
The Composite material elevator trailing edge bar that the utility model provides is less with the central aluminum alloy trailing edge bar phase specific mass adopted of prior art, reduce the weight of trailing edge bar, thus reduce the weight of elevator structure, be convenient to the balance realizing elevating rudder quality, improve aircraft handling efficiency.
Shown in Fig. 1 is the structure of the Composite material elevator trailing edge bar preferred embodiment that the utility model provides.Be the elevating rudder trailing edge bar shown in Fig. 1 according to the trailing edge bar that the Configuration Design of covering on elevating rudder 4, lower covering 5 junction goes out, upper covering 4, the lower covering 5 of elevating rudder are placed in the groove of elevating rudder trailing edge bar respectively, make covering 4, lower covering 5 respectively with the transition face of elevating rudder trailing edge bar on the same face.Shown in Fig. 2 is the cross-sectional view of the Composite material elevator trailing edge bar that the utility model provides, by the elevating rudder trailing edge bar cross section after moulds of industrial equipment mold pressing, curing molding as shown in Figure 2, wherein the shape of foam core 2 is theoretical profile according to elevating rudder and designs, and ply wood 3 is in the surperficial paving of foam core 2.Be provided with resin between ply wood 3 and foam core 2 and make resin melting by frock preheating, ply wood 3 and foam core 2 being linked together by resin, ply wood 3 is integrated with foam core 2 one-tenth.
The trailing edge bar body 1 of a kind of Composite material elevator trailing edge bar that the utility model provides adopts composite material to make, there is compressive resistance compared with aluminum alloy materials high, hardness is large, high temperature resistant, erosion resisting feature, higher temperature is subject to not yielding outside the performance needed for maintenance trailing edge bar, there is the erosion resisting feature not available for metallic material, greatly reduce the maintenance cost of trailing edge bar, improve the safety of aircraft.
A kind of Composite material elevator trailing edge bar that the utility model provides, alleviates trailing edge bar weight, reduces elevator structure weight, be convenient to realize elevating rudder balancing of mass, and then improves aircraft handling quality and efficiency.In addition, adopt the molded technique of vacuum assisted resin transfer membrane, avoid adopting prepreg and hot pressing to fill with curing process, significantly reduce part manufacturing cost.
More than be described in detail in conjunction with Composite material elevator trailing edge bar specific embodiment of the present utility model, but be not to restriction of the present utility model, everyly according to technical spirit of the present utility model, technical scope of the present utility model is all belonged to any simple modification made for any of the above embodiments, also it should be noted that, comprise the combination in any between each part mentioned above according to the category of Composite material elevator trailing edge bar technical scheme of the present utility model.
