在美国宇航局兰利研究中心（LaRC）国家跨音速设施（NTF），有几个项目已经完成或接近完成。在NTF上增加的模型流控/推进模拟试验能力提供了一种独特的跨音速高雷诺数试验能力，这种能力非常适合于推进机体一体化研究、环量控制高升力方案、动力升力和巡航分离流控等方面的研究。一个1992年的老式设施自动化系统（FAS），执行隧道压力，温度，马赫数，模型位置，安全联锁和监督控制的控制功能，被替换为当前的，商业上可用的组件。FAS的升级还包括对更换设施马赫测量系统的设计研究和开发NTF过程和控制系统的基于软件的模拟模型。通过升级后验证风洞试验对FAS升级进行了验证。数据采集系统升级项目涉及设计、购买、建造、集成、安装和验证一个新的数据采集系统，用最先进的硬件/软件取代1990年代初的几个老式计算机系统。本文件介绍了这些努力取得的最新进展。参见参考文献1。
Several projects have been completed or are nearing completion at the NASA Langley Research Center (LaRC) National Transonic Facility (NTF). The addition of a Model Flow-Control/Propulsion Simulation test capability to the NTF provides a unique, transonic, high-Reynolds number test capability that is well suited for research in propulsion airframe integration studies, circulation control high-lift concepts, powered lift, and cruise separation flow control. A 1992 vintage Facility Automation System (FAS) that performs the control functions for tunnel pressure, temperature, Mach number, model position, safety interlock and supervisory controls was replaced using current, commercially available components. This FAS upgrade also involved a design study for the replacement of the facility Mach measurement system and the development of a software-based simulation model of NTF processes and control systems. The FAS upgrades were validated by a post upgrade verification wind tunnel test. The data acquisition system (DAS) upgrade project involves the design, purchase, build, integration, installation and verification of a new DAS by replacing several early 1990’s vintage computer systems with state of the art hardware/software. This paper provides an update on the progress made in these efforts. See reference 1.
