Abstract
The utility model relates to a weight structure of a control surface, and in particular relates to a control surface weight structure which is easy to detach and adjust, belonging to the field of aviation. A detachable and adjustable control surface weight is characterized by comprising a weight box and an adjustable weight, wherein the weight box is fixed on a control surface wingtip skeleton; the adjustable weight comprises a weight block and a weight sheet which are arranged in the weight box. The detachable and adjustable control surface weight, in comparison with the prior art, has the advantages that the weight is detachable and weight mass is easy to adjust.
Description
Technical field
The utility model relates to a kind of counter weight construction of controlsurface, and especially a kind of controlsurface counter weight construction that can be easy to dismounting and regulate, belong to aviation field.
Background technology
The empennage controlsurface adds the requirement that counterweight is the controlsurface balancing of mass.Its effect is the appearance of avoiding the coupled flutter phenomenon of the stabilator that causes in aircraft flight and controlsurface.Usually be controlled on shaft axis by the center of gravity of empennage controlsurface during tail fin design or drop on the slightly front position of shaft axis.By the difficult quality of adjusting structure itself, realize merely, therefore add the counterweight solution in empennage controlsurface leading edge or in controlsurface wing tip leading edge.
Traditional counter weight construction form has piece formula, bullet-nose and bar formula.Flying tail adopts bullet-nose counterweight usually, is installed on the wing tip leading edge; Piece formula counterweight generally is applied in the wing tip leading edge of elevating rudder, yaw rudder or aileron, but selector bar formula counterweight as a supplement, is installed on the controlsurface leading edge simultaneously.When counterweight needs quality of regulation, by changing its inner cavity size or leaded in inner chamber, or the excess stock loss of weight is removed in boring on counterweight, or adds cartridge plate and achieve the goal.
The control method of above-mentioned counterweight lacks alerting ability, fills with plumbous or remove material all to require the assembler to carry out supplementary processing to part, affects efficiency when the aircraft batch manufacturing.For this reason, need to improve the version of counterweight, design a kind of detachable and be easy to the counterweight of regulating.
Summary of the invention
The purpose of this utility model is to solve problems of the prior art, provides a kind of detachable and be easy to the controlsurface counterweight of regulating.
To achieve these goals, the utility model adopts following technical scheme: a kind of detachable, adjustable controlsurface counterweight, and it is characterized in that: described counterweight comprises counterweight box and adjustable weight, described counterweight box is fixed on controlsurface wing tip skeleton; Described adjustable weight comprises clump weight and weight stack, is installed in counterweight box.
Described clump weight is contacted by screw and weight stack, and fixes by packing ring and nut, and described adjustable weight is fixed by the plate nut arranged in screw and counterweight box.
Further, described counterweight box sidewall and clump weight center are equipped with the sunk groove.
At first the part of being sunk in the counterweight box termination during counterweight assembling is fixing with the riveted joint of controlsurface wing tip skeleton, then combines the adjustable weight part, with two screws, is installed on the counterweight box sidewall.On controlsurface trim type frame, by the quick-detachment adjustable weight, and increase as required or reduce the quantity of weight stack, can reach the increase and decrease of weight mass, to realize the purpose of whole controlsurface balancing of mass.
The utility model compared with prior art, has following advantage: detachable, be easy to regulate weight mass.

The specific embodiment
Below in conjunction with 5,6 pairs of the utility model of accompanying drawing, be described in further detail: a kind of detachable, adjustable controlsurface counterweight, described counterweight comprises counterweight box 1 and adjustable weight, described counterweight box 1 is fixed on controlsurface wing tip skeleton; Described adjustable weight comprises clump weight 2 and weight stack 3, is installed in counterweight box; Described clump weight 2 is contacted by screw 4 and weight stack 3, and fixing by packing ring 6 and nut 5, and described adjustable weight is fixed by screw 7 and the plate nut 8 of counterweight box 1 interior setting; Described counterweight box 1 sidewall and clump weight 2 centers are equipped with sunk groove 9.
The version of counterweight box (seeing Fig. 1,2), its profile zone, tip is solid, with the controlsurface rotating shaft the distance farthest, therefore to center of gravity position influence maximum, after determining tip solid area size as required, also adjustable weight should be installed near tip as far as possible, to improve its effectiveness.In addition, counterweight box is fixed on whole counterweight on the controlsurface skeleton, and its end should be made sagging, and the large I of its wall thickness and cavity volume is determined according to desired weight mass.
The version of clump weight (seeing Fig. 3,4), as the mounting seat of weight stack, its auricle thickness of corresponding increase is to improve rigidity.
Sidewall at counterweight box digs groove, in order to adjustable weight is installed.Because counterweight box sidewall and clump weight center are equipped with the sunk groove, make adjustable weight hide its head, the good integrity (see figure 6) after being installed in counterweight box.
At first the part of being sunk in the counterweight box termination during counterweight assembling is fixing with the riveted joint of controlsurface wing tip skeleton, then combines the adjustable weight part, with two screws, is installed on the counterweight box sidewall.On controlsurface trim type frame, by the quick-detachment adjustable weight, and increase as required or reduce the quantity of weight stack, can reach the increase and decrease of weight mass, to realize the purpose of whole controlsurface balancing of mass.
