Abstract
The invention provides a kind of roll angle adjusting means, described device uses threaded collar, jacking nut and end nut to realize the regulation of balance roll angle, simple in construction is easy-to-use, it is ensured that the roll angle error installed when the roll angle of installation during balance calibration and wind tunnel test is less than or equal to 1 '.
Description
Technical field
The invention belongs to balance calibration equipment field, be specifically related to a kind of roll angle adjusting means.
Background technology
Use balance to carry out in aerodynamics force measurement process of the test, generally use key and keyway to coordinate the mode installed by balance
Normal force positive direction be upwards fixed on the angle of attack mechanism of wind-tunnel.When balance calibration, key and keyway is also used to join
Balance normal force positive direction is upwards fixed in balance calibration mounting seat by the mounting means closed, and balance so can be made at wind-tunnel
Test measure and in calibration process keep balance consistent around the roll angle of axle, ideally, balance wind tunnel test measurement with
Roll angle in calibration process is 0 °, to ensure that balance calibration formula can correctly be applied to wind-tunnel aerodynamics force measurement and test
Cheng Zhong.By the way of key and keyway cooperation, realize balance installation in wind tunnel test measurement or calibration process position, but by
In processing gap or error, the roll angle that under practical situation, balance is installed in wind tunnel test measurement and calibration process is not
0 °, all can there is little roll angle, and the most inconsistent at the roll angle that both processes are medium and small, say, that by key and
Keyway is installed location mode and be there is bigger uncertainty in terms of roll angle control, and balance can be caused in wind tunnel test and calibration
During roll angle inconsistent.On the one hand, if balance exists a little roll angle during wind-tunnel measurements, on model
Normal force and pitching moment can produce an interference components to the side force of balance and yawing, cause relatively small lateral
The balance output signal of power and yawing comprises relatively large interference output；On the other hand, when in balance calibration process
When installation exists roll angle, can cause in the normal force component of balance positive direction or the loaded load of pitching moment component to side
Decomposing to power or yawing component, balance side force or yawing thus will be caused to produce output, this output will be easily mistaken for
For being normal force or the pitching moment interference output to side force or yawing, in calibration data processing procedure, deduction interference is defeated
Going out to arise that deduction excess or the problem of deduction deficiency, this will have a strong impact on the calibration result of balance, and cause wind tunnel test to be surveyed
Amount result data degradation.In order to deduct balance exactly, the interference that the roll angle of existence brings is installed in wind-tunnel, manages most
The way thought is exactly during balance calibration, by balance install rolling angle measurement and be adjusted to and wind tunnel test in install
Roll angle is consistent, thus can deduct during balance calibration is measured with wind tunnel test and install the inconsistent mistake brought of roll angle
Difference.
At present, need one balance roll angle adjusting means in a calibration process badly, by adjusting the rolling that balance is installed
Angle, conveniently realizes the roll angle during the roll angle during balance calibration is measured with wind tunnel test consistent.
