In this paper, dynamic performance of 4WD/4WS Electric-driven vehicles is investigated. A coupled dynamic model is introduced for longitudinal, lateral and yawing motion of 4WD/4WS vehicles. Based on the coupled model, dynamic performance is analyzed for steady-state steering, acceleration steering and brake steering, respectively. These non steady-state cornering analysis is important for non-paved road maneuvering, trajectory projection for armored vehicle and future AVCS(Advanced Vehicle Control System) technology. Simulation results are obtained based on a simulink module for the introduced model.<br/>

The performance test of gas management system is dangerous and expensive, so there are many limitations. To solve this problem, this study is performed in order to design a simple and safe pre-test model for the gas management system. For this, subscale test model is designed using similarity method. In order to simulate the plume of high-temperature by using compressed cold air, a nozzle having the same exit Mach number as the actual nozzle is designed. The plume characteristics of real model and similarity model are compared using CFD. In addition, a pnuematic plate test is conducted to verify a numerical method. As a result, the possibility of simulating the actual test environment through the pneumatic test is confirmed.

Aerothermodynamic flowfield characteristics of nozzles were computationally investigated at various nozzle configuration in order to reduce infrared signature. A virtual UAV nozzle was designed through mission and performance analysis. Nozzle and plume flowfield at maximum power was analyzed using a density-based CFD code. Finally, qualitative information for the infrared signature reduction design was obtained through the analysis of the flowfield characteristics at various nozzle configuration.
