1 Introduction

After the separation of the PLF(Payload Fairing) halves, each PLF half is in free falling apart. If both PLF halves are completely destroyed by fire due to the aerodynamic heating, it dosen’t necessary to analysis the accurate dispersed range of the impact point for the PLF halves. However, unfortunately, the PLF halves are not burned out due to the lack of the aerodynamic heating. The easiest approach ...
