The invention discloses a static debugging method for a flexible spray pipe profiles, wherein the method comprises the steps: calculating space coordinates of hinge points fixedly connected to a flexible plate under different spray pipe profiles according to the flexible spray pipe profiles, and calculating to obtain a first elongation of each actuating mechanism according to a position relationship between two points in space; according to the actually-measured molded surface of a spray pipe, calculating the second elongation of each actuating mechanism, solving the difference between the first elongation and the second elongation, serving the difference as the adjustment amount of the length of each actuating mechanism during actual measurement of the molded surface, and adjusting the length of each actuating mechanism; and measuring the adjusted spray pipe profile data again, solving the difference between the solving profile data and the theoretical solving profile, finishing the static state of the profiles if the error requirement is met, and returning to the step 2 if the error requirement is not met. According to the static debugging method for the flexible solving profiles, the actual profile data and the aerodynamic design profile data of the flexible spray pipe are controlled within a given error range through static debugging, so that the accuracy of a wind tunnel simulation mach number and the uniformity of a flow field can be effectively improved.
Description
technical field [0001] The invention relates to the field of precise positioning of spatial geometric objects, in particular to a precise positioning and precise adjustment for the profile of a supersonic wind tunnel flexible nozzle. Background technique [0002] A wind tunnel is a pipeline-shaped ground test simulation device that can artificially generate and control airflow to simulate the flow of air around an aircraft or object, measure the effect of airflow on an object, and observe physical phenomena. In order to realize the simulation requirements of the wind tunnel for supersonic airflow, it is necessary to configure a matching supersonic nozzle before the wind tunnel test section. Due to different supersonic Mach numbers, different supersonic nozzles need to be matched. In the field of high-speed wind tunnels, at first, a supersonic wind tunnel needs to be equipped with several pairs of solid block nozzles according to the simulated Mach number. low efficiency. W...
