Description
Technical field
The utility model belongs to aeroelastic effect test technical field, particularly relates to a kind of variable angle of attack supportive device for high speed flutter model.
Background technology
In flutter test, in order to motion conditions and the supports conditions of correct analogy model, need the supportive device that design and manufaction is special.Design high speed flutter model supports device is more difficult than design low-speed flutter model supports device.Because during design high speed flutter model, the high ram compression of high-speed wind tunnel has higher requirement to the structural strength of model supports device and rigidity, also to meet the requirement of variable angle of attack state and rectification simultaneously, if the version traditionally designing low-speed flutter model supports device designs the supportive device of high speed flutter model, difficulty may be brought to high speed flutter tests.
Summary of the invention
The purpose of this utility model is: provide a kind of variable angle of attack supportive device for high-speed wind tunnel flutter model, when carrying out flutter model high wind tunnel testing, the utility model, while providing enough large holding strength and rigidity, can carry out the replacing of Model angle of attack state easily.
The technical solution of the utility model is: a kind of variable angle of attack supportive device for high-speed wind tunnel flutter model, it is characterized in that, comprising: model base [1], support column [2], Model Beam [3], wind-tunnel connecting bottom board [4], front angle fixture block [5], rear angle fixture block [6], stud location pin [7], front angle fixture block register pin [8], rear angle fixture block register pin [9]
Model base [1] is arranged on wind-tunnel connecting bottom board [4], support that column [2] is arranged in model base [1] by stud location pin [7], Model Beam [3] is arranged on supports column [2] top, support that column [2] rotates around stud location pin [7] rotating band movable model beam [3], front angle fixture block [5] is arranged on model base [1] by front angle fixture block register pin [8] and goes up and be positioned at support column [2] front side, rear angle fixture block [6] is arranged on model base [1] by rear angle fixture block register pin [9] and goes up and be positioned at support column [2] rear side, the position supporting column [2] is limited by front angle fixture block [5] and rear angle fixture block [6].
Further, front angle fixture block [5] and rear angle fixture block [6] are also bolted on model base [1] respectively.
Further, front angle fixture block [5] and rear angle fixture block [6] have multiple angles type.
Further, support that the cross sectional shape of column [2] is circular.
The utility model has the advantages that: the utility model is applicable to flutter model high wind tunnel testing, under the prerequisite ensureing the rigidity of structure and intensity, can by changing all kinds angle fixture block, carry out the replacing of Model angle of attack state, the support column of round section also ensure that the rectification profile of model, at the trial, reduce model installation difficulty, save the installment and debugging time of model.
Accompanying drawing explanation
