The spill inside dimension of described support 12 and aircraft pod external form leave air-out air intake nargin.
The external form of described support 12 is ramp structure.
Is the angle of the ramp structure of described support 12?
Side, two of the outsides of described support 12 respectively is provided with 3 reinforcements.
The lifting bolt 16 of being convenient to carry is installed on described support 12.
Beneficial effect
A kind of Mini Tele-Copter aircraft pod vibration tong that the present invention proposes, the installation that solves helicopter-mounted gondola in vibration test and connection are connected a structural member of forming a connecting link being forced to introduce.The fixture mounting means adopts and is spirally connected, is connected firmly, and easy accessibility.Compare with existing aircraft pod vibration tong structure, Mini Tele-Copter aircraft pod vibration tong of the present invention has following characteristics:
1, with being connected near true installment state of product.
2, natural frequency is not in the vibration sensing frequency band of aircraft pod.
4, adopt aluminum, the light and appropriateness (requiring the weight of vibration tong by 2～4 times of test specimen weight) of quality.Gondola weight 50Kg, vibration tong weight 144Kg, the weight of vibration tong is by 2.88 times of test specimen weight.
5, simple in structure.Adopt the helicopter-mounted gondola vibration tong of cast aluminium casting small size support, the number of subsystem that forms large system is few, and its comprehensive response characteristic is simple.
6, symmetry is good.The center of gravity of vibration tong and aircraft pod assembly drops on the center line of vibration table surface.
