Description
Technical field
It is especially a kind of to match refitting for aircraft control surface mass balance the utility model is related to a kind of counter weight device
It puts.
Background technology
Empennage control surface adds the requirement that counterweight is control surface mass balance.Its effect is to avoid caused peace in aircraft flight
Determine the appearance of the coupled flutter phenomenon of face and control surface.During tail fin design in addition to stabilization is made and control surface has enough rigidity, lead to
Often the gravity's center control of empennage control surface on shaft axis or is fallen in the slightly preceding position of shaft axis.Merely by adjusting structure sheet
The quality of body is difficult to realize, therefore counterweight is added to solve in empennage control surface leading edge or in control surface wing tip leading edge.The reality of counterbalance design
Matter is the mass balance of control surface.
At present, common counter weight construction form has block formula, bullet-nose and formula.Block formula and bullet-nose reuse cast steel of matching are cast
Casting, by changing its interior chamber size or leaded in inner cavity, meets empennage behaviour through machine addition shape to reach increase and decrease balance weight
Vertical face mass balance requirement.Formula counterweight is arranged on empennage control surface leading edge, can be designed to casting, can also be designed to that machine adds
Part is required by drilling to remove excess stock loss of weight or install steel plate additional in counterweight to reach empennage control surface mass balance.Block
Formula counterweight is installed on rudder or elevator wing tip leading edge, and bullet-nose counterweight is installed on flying tail wing tip leading edge, formula counterweight
Rudder or elevator leading edge are installed on, is typically used as the supplementary form of block formula counterweight.
Above-mentioned several counterweights need to be designed, manufacture and install according to control surface structure, and adjusting method is more complicated,
Versatility is poor.For this reason, it may be necessary to improve the structure type of counterweight, design it is a kind of it is detachable, versatile and what be can easily be accommodated matches
Weight.
Utility model content
The purpose of this utility model is to solve problems of the prior art, provide it is a kind of detachable, versatile and
The aircraft counter weight device that can easily be accommodated.
To achieve these goals, the utility model adopts the following technical solution：A kind of aircraft counter weight device, the counterweight
Device includes bottom plate, screw rod, weight stack and self-locking nut；It is provided on the bottom plate and holds the through-hole I that screw rod passes through, in through-hole I
Left and right ends offer through-hole II respectively；The screw rod is in T-shape, and the screw rod body of rod passes through through-hole I, passes through what is screwed togather with screw rod
Self-locking nut is fixed with bottom plate；The weight stack is arranged on screw rod, by consolidating weight stack with the self-locking nut that screw rod screws togather
It is scheduled on bottom plate.
Preferably, washer is further included, the washer is set between self-locking nut and bottom plate and self-locking nut and weight stack
Between.
Preferably, if the quantity of the weight stack is dry plate.
Preferably, the diameter that the through-hole aperture that screw rod passes through is more than screw rod is held on the weight stack.
When carrying out control surface Standard, the quantity of weight stack can be increased or decreased as needed, so as to increasing or
The quality of counterweight is reduced, realize the purpose of entire control surface mass balance or is moved forward and backward the position of weight stack, and pass through certainly
Split nut, washer and self-locking nut are fixed, and so as to change the center of gravity of counterweight, can equally realize entire control surface mass balance
Purpose.
The utility model has the following advantages that：By increasing or decreasing the quantity of weight stack or being moved forward and backward weight stack
The mass balance of entire control surface is realized in position, has the advantages that dismountable, and adjusting method simple and flexible, with a winged
It can be used on machine or same type aircraft, there is stronger versatility.
Description of the drawings
Fig. 1 is the utility model embodiment structure diagram；
Fig. 2 is the structure diagram of Fig. 1 bottom plates；
Fig. 3 is the utility model embodiment scheme of installation；
In figure, 100, counter weight device 1, bottom plate 2, screw rod 3, washer 4, self-locking nut 5, self-locking nut 6, washer
7th, weight stack 8, washer 9, self-locking nut 10, through-hole I 11, control surface wing tip 12, fastener 13, through-hole II.
Specific embodiment
It should be noted that in the present embodiment, " up and down " is described according to shown in attached drawing, it is not to this
The limitation of embodiment.
1-3 is described further the utility model below in conjunction with the accompanying drawings：A kind of aircraft counter weight device, the counter weight device
100 include bottom plate 1, screw rod 2, weight stack 7, washer and self-locking nut；It is provided on the bottom plate 1 and holds the through-hole I that screw rod passes through
10, through-hole II 13 is offered respectively in the left and right ends of through-hole I；The screw rod 2 is in T-shape, and the screw rod body of rod passes through through-hole I 10,
It is fixed by washer 3, the self-locking nut screwed togather with screw rod 4 and bottom plate 1；The weight stack 7 is arranged on screw rod 2, passes through washer
8th, weight stack 7 is fixed on bottom plate 1 by the self-locking nut 9 screwed togather with screw rod 2；Hold the through-hole that screw rod passes through on the weight stack 7
