要实现确保进入空间的目标,重点是降低有效载荷发射成本,提高可靠性。先进运载系统将降低地面操作费用,提高任务可靠性,并且要根据需要做飞行后的检测和维修,而不做例行或定期检测。为此,必须提高技术水平。美国空军宇航实验室已开始执行火箭发动机工况监测系统(RECMS)计划,旨在确定并验证(通过试验)在先进运载系统的研制期间可以应用的关键系统技术。RECMS计划把发动机监测作为和发动机控制器、火箭监测系统及地面处理系统完全一体化的系统,以便在提高发动机可靠性的同时,还保证飞行任务的成功。系统部件通过工况和性能敏感器进行监测,用诊断和预报算法进行分析,通过使用其他先进研制计划验证过的硬件的系统试验进行验证。本文提出了验证火箭发动机工况监测系统关键技术(敏感器、工况/安全监测算法、地面检测设备和专家维修系统数据库)的途径、技术和计划。
To achieve the goal of ensuring access to space, the focus is to reduce payload launch costs and increase reliability. Advanced delivery systems will reduce ground handling costs, improve mission reliability, and perform post-flight inspections and repairs as needed rather than routine or periodic inspections. To this end, we must improve the technical level. The United States Air Force Aerospace Laboratory has begun implementing the RECMS program to identify and validate (by testing) key system technologies that can be applied during the development of advanced launch systems. RECMS plans to use engine monitoring as a fully integrated system with engine controllers, rocket monitoring systems and ground handling systems to ensure the success of the mission while improving engine reliability. System components are monitored using condition and performance sensors, analyzed using diagnostic and forecasting algorithms, and validated through systematic testing of hardware validated by other advanced development plans. This paper presents ways, techniques, and plans for validating key technologies (sensors, condition / safety monitoring algorithms, surface inspection equipment and expert maintenance system databases) for the rocket engine condition monitoring system.
