Description

Technical Field

[0001] This invention relates to the field of wind tunnel testing technology for aircraft, and in particular to a method, system, equipment, and medium for optimizing the consistency of wind tunnel test data for aircraft. Background Technology

[0002] In the field of aerospace aerodynamics research, wind tunnel testing is a core means of obtaining the aerodynamic characteristics of aircraft. Among them, wind tunnel force measurement tests and wind tunnel pressure measurement tests are two fundamental and crucial test types. Wind tunnel force measurement tests directly acquire the aerodynamic and moment parameters (including lift, drag, side force, pitch moment, roll moment, and yaw moment) of the entire wind tunnel model and key components through high-precision mechanical measurement devices (typically multi-component strain gauge force balances). The measurement results directly reflect the overall mechanical response of the model under specific incoming flow conditions. Wind tunnel pressure measurement tests, on the other hand, collect surface pressure data at a limited number of discrete points on the model surface through a pressure sensor array (such as miniature piezoresistive sensors or piezoelectric sensors). Combined with the model surface topology, the aerodynamic characteristics of the entire aircraft or components are obtained through integral calculations. This test focuses more on revealing the interaction mechanism between the flow field and the model surface.

[0003] However, in practical engineering applications, there are often significant systematic deviations in the results of the two types of tests. The core causes include three aspects: First, model manufacturing errors. Force measurement models need to ensure stiffness to avoid interference from balance measurements, while pressure measurement models need to reserve sensor installation channels. The two have inherent differences in geometric shape (such as surface finish and the outline of key aerodynamic components) and structural stiffness, resulting in inconsistent flow field characteristics. Second, differences in measurement system accuracy. The measurement accuracy of force balances is affected by temperature drift and load coupling interference, while pressure sensors have problems such as zero-point drift and dynamic response hysteresis. The calibration standards and traceability systems of the two types of sensors are different, further aggravating data deviations. Third, disturbances in the test environment. There are subtle differences in the uniformity of incoming flow (such as turbulence intensity and Mach number stability), model installation attitude (such as the calibration accuracy of angle of attack and sideslip angle), and wind tunnel flow field boundary conditions (such as the tunnel wall interference correction coefficient) between the two tests, which makes it impossible to completely reproduce the test conditions.

[0004] Currently, the mainstream deviation correction method in engineering relies on manual comparison correction. This involves conducting individual component force measurement tests and comparing the component's force measurement data with the corresponding component's pressure measurement integral data point by point, establishing a correction factor matrix to iteratively correct the pressure measurement results. While this method can reduce deviations to some extent, it has significant technical drawbacks, specifically:

[0005] 1. Low testing efficiency: Individual force measurement test schemes and models need to be designed for each key component such as wings, fuselage, and tail. To complete the correction of the whole aircraft, multiple rounds of tests such as whole aircraft force measurement, whole aircraft pressure measurement, and multi-component force measurement need to be carried out in sequence. The entire correction cycle usually takes several weeks or even months, which is difficult to meet the high efficiency requirements of aircraft aerodynamic design iteration.

[0006] 2. High dependence on experience: The correction process relies on the engineer's understanding of aerodynamic flow mechanisms (such as shock wave location, boundary layer separation, and vortex interference), and the selection of correction factors and the direction of iteration are highly subjective. For complex flow fields (such as transonic flow and high angle-of-attack separated flow), empirical judgment is prone to deviation, resulting in insufficient reliability and robustness of the correction results.

[0007] 3. High overall costs: The design and fabrication of additional component force measurement models require significant materials and labor, and multiple rounds of testing consume wind tunnel testing resources, leading to a substantial increase in testing costs. Furthermore, the manual correction process requires a team of experienced engineers, further driving up labor costs. Summary of the Invention

[0008] To address the aforementioned issues, this invention proposes a method, system, equipment, and medium for optimizing the consistency of wind tunnel test data for aircraft. By integrating the geometric and aerodynamic features of the model, a dual correction factor model is constructed, eliminating manual intervention and improving correction efficiency and reliability.
