Simulation systems with hardware-in-loop are composed by three-Axis virtual flight motion simulator
simulation computer
load torque simulator
and visual simulation systems. Three-Axis Virtual Flight Motion Simulator are used to simulate the attitude of missile in simulation system with hardware-in-loop
so its performance influenced the result of simulation directly. This paper mainly analyzed the factors which influenced the performance of a three-Axis virtual flight motion simulator which we are used now in the lab
then analyzed the entire simulation system's error caused by these factors through numerical simulation method. By analysis we can see that bandwidth is the main factor influenced the precision of simulation systems with hardware-in-loop
mechanical device installation error and measurement error may also cause some errors of the systems at the same time.

In order to realize missile real-time change flight trajectory
three-loop autopilot is setting up. The structure characteristics
autopilot model
and control parameters design method were researched. Firstly
this paper introduced the 11th order three-loop autopilot model. With the principle of systems reduce model order
the 5th order model was deduced. On that basis
open-loop frequency characteristic and closed-loop frequency characteristic were analyzed. The variables of velocity ratio
dynamic pressure ratio and elevator efficiency ratio were leading to correct system nonlinear. And then autopilot gains design method were induced. System flight simulations were done
and result shows that autopilot gains played a good job in the flight trajectory
autopilot satisfied the flight index. 2012 IEEE.

In this paper
a strong coupled CFD-CSD method is developed to simulate the aeroelastic phenomena. The CFD solver is based on the finite-volume algorithm for the Navier-Stokes equations on unstructured grid. The CSD solver solves the aeroelastic governing equations in the modal space. Their coupling is realized by a dual-time method. The spring-based smoothing method is adopted to deform and regenerate the aerodynamic grid. Two test cases are selected to validate the authors' method for static and dynamic aeroelastity .The results of the simulation for the static aeroelastic problems of a missile wing show that the Lift Coefficient and Drag Coefficient are severally 7% and 5% lower than those don't consider the elasticity of the wing. The results for the flutter boundary prediction of the AGARD 445.6 wing have been proved much closer to the experiment than using the DLM. This method can describe the effects of fluid viscosity more exactly for highly nonlinear transonic flight conditions. The calculation has proved reliable in the subsonic regime
but not accurate enough in the supersonic regime. 2011 IEEE.
