Unmanned Aerial Vehicles or UAVs are becoming more popular nowadays, and in-depth study of quad-copter UAV falls into detrimental situations required more investigations. In this work not only the aerodynamic parameters of quad-copter, but also the physical phenomenon for quad-copter flying under severe weather conditions are numerically simulated. An APC 10x4.7 rotor is first chosen as the validation benchmark case. Due to recent aviation safety concerns, the free-fall situation of quad-copter will be our major concern, and the worst realistic situations under severe weather condition are simulated, such as flying in the heavy rain and different typical gust wind conditions, for both the quad-copter hover and forward flight situations. It is found that the heavy rain effect is not as severe as the downdraft or the horizontal gust wind situations. It is hoped that this research can help the quad-copter UAV industries and academia to understand more about how adverse situations’ impact on quad-copter performance.
