Abstract
An air data sensor device using a flow around a cylinder is provided. The air data sensor device may include a sensor measurement unit which includes a sensor body provided in a cylindrical form including a hollow inside, a plurality of pressure measurement holes disposed on an outside of the sensor body, and a thermostat attached to one side of the sensor body, and a signal processing unit which includes a pressure sensor connected to the plurality of pressure measurement holes, and a microprocessor connected to the pressure sensor to perform calculation. A main pressure measurement hole having a high pressure value may be selected from the plurality of pressure measurement holes, pressure distribution may be calculated, and at least one of an angle of attack, a static pressure, and a total pressure may be calculated using the pressure distribution.
