초록정보

A multiple-lunching simulation program is developed, which analyzes mallaunch and determines optimal firing time interval for improvement of mallaunch in the 3 dimensional MRL (multiple rocket launcher) MODEL with 9 degrees of freedom at given firing attitudes. The solution technique consists of quantitative time domain analysis and qualitative frequency domain analysis for the purpose of assessing the dynamic characteristics of the model. The time domain analysis is implemented on the time varying nonlinear system by using multirate time integration, and the frequency domain analysis is implemented on the linearized time varying system by introducing weighted frequency response function and power spectrum of stationarized forcing function. Thus, the optimization procedure minimizes the sum of output power spectrum for the entire operating range of launching angle by varying firing time interval. The simulation studies with 6"MRL are performed to verify the effectiveness of this method in determination of optimal firing time interval and dynamic response. The results show that the mallaunch value of 11.8 mil at the worst time interval is reduced to 2.3 mil at the optimal firing time interval.
