Abstract

The invention relates to a sports sailboat sail wing wireless pressure sensor and a pressure testing apparatus. The pressure testing apparatus is structurally characterized in that a plurality of wireless pressure sensors are respectively packaged inside transparent bags and then respectively fixed on a plurality of flexible test laths. The flexible test laths are respectively fixed on the periphery of a sports sailboat sail wing. A data collector transmits information to the wireless pressure sensors and a PC machine through a wireless network. Each wireless pressure sensor is structurally characterized in that a capacitive type pressure sensor is connected with a charge amplifier; the charge amplifier and a wireless module are connected with a single-chip microcomputer minimum system; an L-shaped unipole antenna is connected with the wireless module; and a button cell supplies power to each part of the wireless pressure sensor. A fixed round hole is arranged beside each wireless pressure sensor arranged on the flexible test laths. The data collector collects data of all wireless pressure sensors. By means of each sensor position coordinate, a pressure graph of the whole sail wing face can be drafted.

Description

technical field [0001] The invention relates to a wireless pressure sensor and a pressure testing device for a sail wing of a sports sailboat, belonging to the fields of electronic technology and fluid mechanics. Background technique [0002] The early aerodynamic performance experiments of the sail only tested the overall aerodynamics of the sail, but did not test the pressure distribution on the windward and leeward sides of the sail, and did not analyze the flow details of the flow field around the sail. Flow separation at the top and bottom of the sail wing, flow separation at the aftersail edge of the sail wing, flow separation during trimming, etc. Since the sail of a sailboat is a soft sail, the shape of the sail changes with the wind load during the process of trimming or swinging the sail, and at the same time, the changing shape of the sail affects the distribution of air flow around the sail. Therefore, the fluid-structure coupling effect of the sail wing cannot ...
