Wind　disturbance　could　render　thrust　and　power　variation　or　even　causing　roll　which　is　difficult　to　maintain　a　steady　flight　in　gust　especially　when　the　horizontal　or　vertical　wind　is　involved.　In　this　paper,　the　horizontal　wind　and　vertical　wind　are　presented　to　study　the　influence　of　wind　disturbance　on　aerodynamic　characteristics　of　the　quadrotor　aircraft　in　hovering　by　experiments　and　numerical　simulations.　First,　the　simplified　aerodynamic　model　with　the　wind　disturbance　was　analyzed　in　detail.　Also,　the　low-speed　wind　tunnel　tests　were　performed　to　obtain　the　thrust　and　power　variation　of　the　quadrotor　aircraft　with　rotor　spacing　ratio　s=1.1-1.8　in　both　horizontal　and　vertical　winds　of　0-5　m/s　with　the　rotational　speed　ranging　from　1500　to　2300　rpm.　Finally,　the　simulations　are　performed　by　utilizing　the　Computational　Fluid　Dynamics　(CFD)　software　ANSYS　to　study　the　flow　field　distribution　of　quadrotor　with　the　influence　of　the　wind　disturbance.　The　comparison　between　experimental　results　and　simulation　results　shows　that　the　quadrotor　achieves　better　aerodynamic　performance　with　larger　thrust　and　smaller　power　consumption　at　rotor　spacing　ratio　s=1.8.　Additionally,　the　quadrotor　can　effectively　resist　the　horizontal　wind　disturbance,　which　will　bring　larger　power　loading　for　the　quadrotor,　especially　at　2.5　m/s.　However,　the　vortices　near　blade-tip　move　upwards　and　deform　with　the　influence　of　vertical　wind,　resulting　in　the　reduction　of　thrust　and　aerodynamic　performance　of　the　quadrotor.
