本报告介绍了大力神ⅢC运载器所使用的新的数字飞行控制系统(DFCS)的研制情况及其特性。在这个系统里,助推阶段和滑行阶段的飞行方程与制导方程由一个新的通用数字计算机按时间分割进行计算。此系统的软件可适应范围广泛的飞行任务和多种载荷。此系统的软件还有故障检测和修正逻辑,从而提高了任务的可靠性。本报告讨论了研制数字飞行控制系统软件的专门方法和技术,也讨论了研制过程中有关数字滤波器精度、环境噪声感受度以及弯由振型折叠效应等问题的采些解答。
This report describes the development and characteristics of the new Digital Flight Control System (DFCS) used by Hercules III C vehicles. In this system, the flight and guidance equations for the boost and taxi stages are time-divided by a new general-purpose digital computer. The system’s software accommodates a wide range of missions and loads. The system’s software also has fault detection and correction logic, which increases the reliability of the task. This report discusses specialized methods and techniques for developing digital flight control system software. It also discusses some of the answers to questions about the accuracy of digital filters, the perception of ambient noise, and the bending caused by vibration modes during development.
