Abstract
The invention belongs to composite structure design fields, are related to a kind of blade tip carbon fiber structural.The present invention is the structure wrapped up after integral-filled by the original blade tip of change, by the way that several parts of blade tip filling point are filled, it is wrapped up after filling, this structure will not wrap up cloth because of blade tip and be fallen by reconditioning, and reduce blade tip intensity, guaranteeing blade service requirement simultaneously, is reducing the machining accuracy for being used cooperatively metallic conduit with blade, cost greatly reduces.
Description
Technical field
The invention belongs to composite structure design fields, are related to a kind of blade tip carbon fiber structural.
Background technique
As national economic strength enhances, make great efforts the development to high-tech areas such as Aeronautics and Astronautics, develops all kinds of boats
It, aviation aircraft, need to carry out a large amount of wind tunnel test work, meanwhile, the resistance to compression heat resistanceheat resistants of a variety of materials test, automobile, height
Fast train, the air drag of ship, heat-resisting and compression test are also required to carry out wind tunnel test.Therefore low speed, transonic speed, ultrasound
Fast, hypersonic all types of wind-tunnel are rapidly developed, up to the present, China possessed low speed, high speed, ultrahigh speed and
The wind-tunnel such as shock wave, electric arc, for the variation to meet the market requirement, the product of my company will also do corresponding adjustment.
Compressor is the core equipment of continous way transonic wind tunnel, and compressor blade therein is key in core, is
The overall weight for reducing compressor, reduces the starting inertia of compressor, and composite material relies on its light weight, superior specific strength,
It is preferred as compressor blade that the advantages that specific stiffness, specific modulus and corrosion resistance, gradually replaces metal material.For reduce energy consumption,
Reduce compressor weight and rotary inertia, the foam sandwich using carbon fibre composite as the main material of compressor blade
Structure.
Wind-tunnel pipeline is made of metallic conduit, since factors, the blade tip such as deformation need after machining accuracy and assembling
Reconditioning quality facilitates blade to carry out the gap of reconditioning adjustment blade tip and wind-tunnel pipeline when with wheel hub and installation, reaches smooth use
Purpose.Existing structure uses foam sandwich structure because of blade.Blade tip must have filler, and structure is shown in Fig. 1, and reconditioning can make surface layer
Package cloth reconditioning is fallen.Wind tunnel blade has the characteristics that high-revolving operation, and blade tip linear velocity is up to 250m/s or more, operational process
In centrifugal force it is bigger, easily cause filler and blade body to separate, cause blade damage.
Summary of the invention
The purpose of the present invention: it is an object of the invention to overcome since blade tip package cloth is by after reconditioning, blade tip filler because
Centrifugal force effect and blade body separation, cause blade damage.
Technical solution of the present invention: a kind of blade tip carbon fiber structural, including the filling of outer layer carbon cloth 1, foam 2, blade tip
Carbon fiber 3, blade tip carbon fiber wrap up cloth 4；Outer layer carbon cloth 1 is wrapped in 2 outside of foam, and blade tip filling carbon fiber 3 is placed on leaf
Point, then cloth 4 is wrapped up by blade tip carbon fiber and is wrapped up；It is characterized in that, outer layer carbon cloth 1 is wrapped in foam into a ladder
2 outsides are divided by blade tip carbon fiber patch 5 and are filled several times to outer layer carbon cloth 1 at ladder by patch mode, every patch
It is complete once to be wrapped up with blade tip carbon fiber package cloth 4.
The blade tip carbon fiber package cloth 4 and outer layer carbon cloth 1 are docked in blade upper surface, in this way will not be because of packet
It is wrapped with extra cloth and causes blade surface local deformation.
5 shape of blade tip carbon fiber patch is used cooperatively into a ladder according to outer layer carbon cloth 1.
Beneficial effects of the present invention: the present invention is the structure wrapped up after integral-filled by the original blade tip of change, is led to
It crosses and several parts of blade tip filling point is filled, wrapped up after filling, this structure will not wrap up cloth because of blade tip and be fallen by reconditioning, and
Blade tip intensity is reduced, is guaranteeing blade service requirement simultaneously, is reducing the machining accuracy for being used cooperatively metallic conduit with blade, greatly
Big reduces costs.

Specific embodiment
The following further describes the present invention with reference to the drawings:
As shown in Figure 2 and Figure 3, a kind of blade tip carbon fiber structural carries out blanking, outer layer carbon cloth 1 by blanking machine first
Length successively increases inside-out, into a ladder, sees Fig. 3；5 blanking shape of blade tip carbon fiber patch cooperates outer layer carbon cloth 1
Ladder-like use, is shown in Fig. 2；
When blade layer is spread, guarantee that outer layer carbon cloth 1 is wrapped in 2 outside of foam into a ladder, pastes by blade tip carbon fiber
Piece 5, which divides, is several times filled outer layer carbon cloth 1 at ladder by patch mode, every to have pasted primary blade tip carbon fiber package
Cloth 4 is wrapped up, and is then docked, and as a result sees Fig. 3.
The blade tip carbon fiber package cloth 4 and outer layer carbon cloth 1 are docked in blade upper surface, in this way will not be because of packet
It is wrapped with extra cloth and causes blade surface local deformation.
5 shape of blade tip carbon fiber patch is used cooperatively into a ladder according to outer layer carbon cloth 1.
