| Abstract: | We analyze shortcomings of quondam air data experimental system. A new air data experimental system which is based on ARM microcontroller and closed-loop pressure control is designed. A composition scheme of the new experimental system is put forward. We also introduce the methods of structural design and software design of the experimental system in detail. The new experimental system has advantages of small size, high integration, high accuracy of pressure measurement, and precise control of pressure. The experimental result indicates that the new system can help students more easily understand the calculation principle of flight atmospheric parameters. This system is suitable for the demand of this subject and has the characteristic of aerospace. |
