This paper presents aerodynamic analysis of an unmanned small-scaled gyroplane with a rotor having cyclic pitch system.A comprehensive nonlinear model is derived for it which involves force and moment generation mechanism for the flying vehicle.The nonlinear model is linearized with approximations and deduced on a prescribed flight condition.Our gyroplane dynamic modal response is further reconfigured and reveal its differences associations among helicopters and classic autogiros.A study is performed to investigate the effect of forward flight speed and center of gravity (CG) placement on modal response.The results suggest an appropriate CG location to reduce instability.

大白菜雷阵雨前后的管理大白菜生长在夏秋之际，如果在夏季多雷阵雨，加上管理的好，大白菜可增产１５～２０％。其原因是由于雷阵雨有雷电，空气中的氮和氧化合成二氧化碳溶于水变成浓度很低的硝
