The fast maneuver of aerovehicles is one of the typical multiphysics coupled problems. The numerical virtual flight (NVF) simulation is a very useful and effective tool to analyze this kind of multiphysics problems. However, any computational-fluid-dynamics-based NVF solver should be verified and validated before engineering applications. In this work, the numerical virtual flight simulation platform Hybrid platform for engineering and research on FLOW - Numerical Virtual Flight System (HyperFLOW-NVFS), developed in our previous work (Zhang, L. P., Chang, X. H., Ma, R., Zhao, Z., and Wang, N. H., “A CFD-Based Numerical Virtual Flight Simulator and Its Application in Control Law Design of a Maneuverable Missile Model,” Chinese Journal of Aeronautics, Vol. 32, No. 12, 2019, pp. 2577–2591), is validated preliminarily by wind-tunnel virtual flight testing. A missile model is adopted to carry out virtual flight testing and numerical simulations. Three typical pitching-up maneuvering actions are tested to validate the capability of our NVF solver, including pitching up with a closed-loop attitude controller and an acceleration controller. The numerical results agree generally well with the experimental data, except for the states at a high angle of attack, which means that our NVF solver displays the potential for simulating complex multiphysics coupled problems.
