“…One most complicated is the Advanced Simulation Center (ASC) in Redstone base. In 1970s, HILS systems are based on the analog-digital (or hybrid) computers, such as the patriot hybrid HILS system [55], the semiactive missile hybrid HILS system [56], the hybrid HILS system in RDEC [57], and the TR-I rocket hybrid HILS system [58]. In 1980s, alldigital computers emerge, which makes the hybrid computers gradually replaced by full-digital computers in HILS systems.…”

Wind tunnel based Virtual Flight Testing (VFT) is a dynamic wind tunnel test for evaluating flight control systems (FCS) proposed in recent decades. It integrates aerodynamics, flight dynamics, and FCS as a whole and is a more realistic and reliable method for FCS evaluation than traditional ground evaluation methods, such as Hardware-in-the-Loop Simulation (HILS). With FCS evaluated by VFT before flight test, the risk of flight test will be further reduced. In this paper, the background, progress, and prospects of VFT are systematically summarized. Specifically, the differences among VFT, traditional dynamic wind tunnel methods, and traditional FCS evaluation methods are introduced in order to address the advantages of evaluating FCS with VFT. Secondly, the progress of VFT is reviewed in detail. Then, the test system and key technologies of VFT for FCS evaluation are analyzed. Lastly, the prospects of VFT for evaluating FCS are described.
