Abstract

The purpose of this research is to determine the dynamic Magnus effect data of a spinning projectile in wind-tunnel testing. In the present work, the high-speed wind-tunnel tests for the Magnus effect measurements were conducted on a 155-mm spin-stabilized projectile model in the Agency for Defense Development's Tri-Sonic Wind Tunnel at spin rates about 12,000 rpm. The test Mach numbers ranged from 0.7 to 2.0, and the angles of attack ranged from -4 to +10 deg. The validity of the wind-tunnel measurement techniques was evaluated by comparing them with the previous test results on the same configuration. The experimental results show that fair to good agreement is obtained with resonable accuracy.

본 연구의 목적은 풍동시험을 통해 회전발사체에서 발생하는 동적 마그너스 효과를 실험적으로 측정하는데 있었으며, 이를 위해 약 12,000 rpm으로 회전하는 155-mm 회전발사체 실험모형에 작용하는 마그너스 특성의 측정을 위한 고속풍동실험을 국방과학연구소 삼중음속풍동에서 수행하였다. 실험시의 마하수는 0.7~2.0까지였으며 이때의 받음각 구간은 -4~+10 deg이었다. 풍동실험 측정기법의 유효성 평가를 위해 동일형상 모형에 대해 기 수행하였던 마그너스 측정결과와의 비교검토를 수행하였으며, 기존 연구결과들과 잘 부합됨을 확인하였다.
