  • Research on Direct Filament Winding Multi-Segment Rocket Motor

説明

Breakthrough technologies are needed to enhance the ability of rocket motor． In this research， the manufacturing method of conventional rocket motors has been dramatically changed by using the Multi-Segment Technology and Direct Filament Winding (DFW) Technology． These technologies enable a great increase of propellant mass ratio, Multi-Thrust and improvement in flight performance． A triple thrust pattern and 2-pulse thrust were demonstrated by static firing tests of prototype rocket motors manufactured using the Multi-Segment Technology and DFW technology． From a flight performance analysis, flight range extension by 60% and terminal velocity enhancement by 50% can be expected when these technologies are applied to a φ0.3m-class rocket．
