A Novel Method for Total Pressure-Air Velocity Information Processing Based on Computer Numeric Analysis

从数值计算方法的角度对大气数据校验系统设计中空速、指示空速与动压、静压转换关系进行研究,提出了一种新的转换方法。在PC计算机和ARM嵌入式计算机S3C2410上进行了模拟仿真,给出了计算程序和分析结果,与传统方法相比,具有转换速度快、程序简捷、精度高的特点,该方法用软件容易实现,可以很方便地应用到其它传感器的研究与设计中。

In design of the air data testing and calibrating system, the relationship between the total air pressure, static air pressure and the flying velocity, indicating flying velocity has been studied based on numeric analysis,a novel method has been invented. This method has been simulated on a personal computer and an embedded ARM processor S3C2410,the C program is provided, and the result is presented and discussed. Compared with the traditional method, it is fast, simple and accurate. It is easy to realize by programming and can be widely used on other sensors＇ designing and applying.
