为了研究高速、小模型弹丸的空气动力实验方法,基于MAF风洞基本结构和实验原理。设计了高速大数据量的数据采集系统硬件,编制了所建立的空气动力计算公式的测试和数据处理软件。以某弹丸模型为例,进行了空气动力实验参数采集并与FD-04风洞在相同条件下的实验结果进行对比,证明实验方法和数据采集技术可用于实际工程。

In order to study the aerodynamic experimental methods of the high-speed and small model projectiles based on the basic structure and the experimental principle of the MAF wind tunnel. Data acquisition system hardware of high-speed and large data was designed, and the test and data processing software was designed according to aerodynamic formula. Take the some model of projectile for example, aerodynamic experimental parameters were collected, and were compared with the results of the FD-04 wind tunnel under the same conditions. It shows that the experimental methods and testing technology can be used for practical engineer-ing applications.
