Abstract

The invention discloses a control surface angle sheet assembling and disassembling method. The method is based on a wind tunnel test model for changing a control surface angle by an angle sheet, and the model comprises a model body, a measuring rudder arranged on the model body, and a plurality of angle sheets of which the bottom ends are at different angles. The measuring rudder comprises a rudder surface and a rudder shaft fixedly connected to one side of the rudder surface, the rudder shaft is provided with a linear groove used for fixing the angle of the rudder surface, one side of the model body is provided with a mounting hole, and the rudder shaft is movably connected in the mounting hole; and a first compression screw is detachably connected with the model body in the middle of the top of the angle sheets, and the bottom ends of the angle sheets abut against the bottom end of the linear groove. The method has the beneficial effects that the effect of changing the angle of the control plane can be achieved, meanwhile, the angle sheets can be inserted into the model body or pulled out of the model body under the driving of the compression screw, the angle piece replacement process is accelerated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind tunnel tests, and more specifically, the invention relates to a method for installing and disassembling rudder surface angle pieces used for the installation and positioning of aircraft rudder surfaces and hinge moment balances. Background technique [0002] When carrying out the hinge moment test, the accuracy and reliability of measuring the transformation of the rudder angle has a decisive influence on the test data. At present, there are two commonly used methods for measuring rudder angle transformation: (1) angle piece positioning, screw compression; (2) fixed deflection angle overall processing. Among them, when the first method is used, the angle piece needs to be inserted into the model, and the angle piece needs to be taken out when changing the rudder deflection angle. At present, the commonly used method is to set threaded holes on the angle piece. When disassembling, screw the stud into...
