Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, a kind of small-size turbojet engine vector spray testboard, including hold-down support, six COMPONENT BALANCEs, branch
It supports seat, pillar and grips component.
Hold-down support is for fixing entire testboard, and hold-down support fixed setting is on the ground.
Six COMPONENT BALANCEs are used for the intrinsic thrust performance of test engine and the power and power under vector spray difference rotational angle
Square characteristic, six COMPONENT BALANCEs are mounted by means of bolts on the support panel of hold-down support.Six COMPONENT BALANCEs are a kind of strains
Balance can measure six kinds of sharing parts of the load simultaneously, including：Normal force, lateral force, axial force, pitching moment, yawing and rolling
Torque needs to calibrate six COMPONENT BALANCEs before use.
Balance protection board sets the upper surface for being connected to six COMPONENT BALANCEs, for protecting six COMPONENT BALANCEs.Balance protection board
