Abstract

The invention provides a segmented trace hinge moment balance and belongs to the technical field of aerospace force measurement test aerodynamic force measurement. The segmented trace hinge moment balance is of an all-steel-component combined structure. The segmented trace hinge moment balance comprises a measuring device, a thermal insulation device and a limiting protection device. The measuring device comprises a simple-component balance and a six-component beam balance, wherein the central axis of the simple-component balance is perpendicular to the central axis of the six-component beam balance; the simple-component balance is fixed at the free end of the six-component beam balance and is used for measuring a trace hinge moment, and the six-component beam balance measures all the aerodynamic force borne by a control surface and thus corrects the disturbance from the rest of aerodynamic force to the trace hinge moment, so that the resolution ratio and the accuracy of measurement can be improved. The thermal insulation device is arranged on the outer side of the measuring device, so that the heat protection performance and the thermal insulation performance of the measuring device are improved, the temperature effect is reduced, and the accuracy of trace hinge moment measurement in wind tunnel tests under the condition of a high Mach number is improved.

Description

technical field [0001] The invention belongs to the technical field of aerodynamic force measurement for aerospace dynamometer tests.
