用解题法调试某型飞机斜板系统

Ground Setting of Scheduled Control Law for an Inlet Ramp Control System by Using a Solution Approach to Ramp Angle

某型飞机是国家重点工程项目之一 ,该机进气道自动调节系统采用计算机进行结算、调节与控制 ,增加了系统调节精度和可靠性。但在首批飞机的调试中 ,极难实现技术条件的要求 ,且无规律可循。对此 ,我们通过对斜板调节机理的研究实验 ,摸索出了斜板在大小πk 时调节曲线的对比规律 ,设置了调整计算方程 ,可靠地解决了这一难题。

Ground setting of an inlet ramp control system is intended to be performed by a computer, but in initial settings of the system, it is difficult to met the requirement in the system specification. To provide a solution to this problem, investigation into the ramp control mechanism was conducted. A setting equation was derived through the comparison of the ramp control curves for high and low π k ’s.
