软件逆向工程技术在2.4 m风洞核心控制程序研制中的应用

摘要

To solve the problem that several C language executable modules without source code exist in the core-control-system program of 2.4 m wind tunnel which may severely hinders the future upgrade of the system, software reverse engineering techniques were adopted to develop the newsub-stitutional module. Methods and procedures, debugging scheme through which the new modules were developed are depicted in detail and the actual control curve of the new program is also presented. The testing result data show that the control accuracy of flow field and model attitude is equal or better than that of the old software, and the newly developed modules has been put into use in the wind tunnel testing, so the development of the software is successful.%为解决2.4 m风洞核心控制程序中存在几个没有源代码的C语言执行模块严重制约系统平台升级的问题，采用软件逆向工程技术研制新的替代模块。介绍了模块重新研制的步骤方法、软件调试方案等，给出程序改造后的实际控制曲线。试验数据结果表明：风洞流场和模型姿态控制精度达到或优于原来系统的指标，并已投入风洞试验实际应用，证明软件研制是成功的。
