| Abstract |
In this paper, we model the total mass and mass distribution to simulate the missile-target interaction analysis of aircraft. And the difference of mass of fuel was also considered, because it is about 40 percent of total mass when it is full-filled. The aircraft FE model was developed by determining mass distribution. And aircraft FE model was verified by impact analysis simulated by AUTODYN. Through the developed aircraft FE model, the impact on the various surface of target, which cannot be analyzed by Riera model, can be analyzed by the missile-target interaction analysis. The large commercial B747 aircraft was used for the missile which is using for long distance flight. To determine the mass model of aircraft, the Riera approach was used for the reference impact time history graphs which provided by OECE-NEA (2002) and Arros and Doumbalski (2007). |
