Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0053] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, in the...

Abstract

The invention discloses a method, system and device for measuring surface pressure of a wing, and the method comprises the following steps of the first step, dividing the wing into a plurality of wingblocks by a block division strategy, so that there is no gradient in the surface pressure between each point in each wing block; the second step, obtaining the position of a strain measurement pointon the wing based on the finite element model and the block strategy; the third step, installing a strain measurement component at the position of the strain measurement point on the wing to perform the strain measurement; and the fourth step, obtaining the pressure of each wing block on the wing according to the measured strain data, that is, obtaining a pressure distribution value on the wing. By dividing the wing into a plurality of wing blocks by the block division strategy, obtaining the position of the strain measurement point on the wing by using the finite element model and its calculation results, and reversely calculating the actual pressure value of the wing during the work process by combining the measurement of the actual strain of the strain measurement point on the wing, theprecision of the surface pressure obtained of the wing is high, the implementation method is convenient, the economy is high, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pressure measurement, in particular to a method, system and device for measuring wing surface pressure. Background technique [0002] In the design and manufacture of various types of wings, it is often necessary to calculate and measure the surface pressure of the wing in order to analyze and study the distribution of the wing surface pressure. In the prior art, the pressure sensor is usually directly installed on the surface of the wing or a pressure measuring hole is arranged in the wing to transmit the pressure signal to the pressure sensor with a pipeline. The pressure sensor converts the pressure signal into a weak electrical signal, and the weak electrical signal is amplified and processed to restore the pressure value. [0003] Currently, there are two methods for obtaining wing surface pressure: [0004] The first one: based on the CFD (Computational Fluid Dynamics) method, use this method to c...
