The invention discloses a rotor aircraft near-surface effect test device, and belongs to the technical field of aircraft aerodynamic characteristic testing, the test device comprises two lifting supports, a main beam is arranged between the two lifting supports, a connecting piece is arranged on the main beam, and a support arm, a tension-torsion sensor and a rack are fixed below the connecting piece; the bottoms of the supporting arms are fixedly connected with the cross center of the rack, and the cross ends of the rack are fixedly connected with direct-current brushless motors and rotor wings; the rack is provided with a plurality of mounting holes according to the size of the actually used direct current brushless motors, so that the direct current brushless motors and the rotor wings can be mounted at different radial positions of the rack, and the distance between each direct current brushless motor and each rotor wing is controlled, thereby forming a simplified four-rotor-wing or composite-wing-rotor-wing layout; therefore, the mutual influence of the rotors of the aircrafts with different rotor distances in the water-gas mixing flow field is reproduced, the function of testing multiple aircrafts by one machine is realized, and the universality is good.

    本发明公开了一种旋翼类飞行器近水面效应试验装置,属于飞行器气动特性测试技术领域,试验装置包括两个升降支架,两个升降支架之间设有主梁,主梁上设有连接件,连接件下方固定有支臂、拉扭传感器和机架;支臂的底部与机架的交叉中心固定连接,机架的十字交叉端上均固定连接有直流无刷电机和旋翼;机架根据实际使用直流无刷电机的尺寸开有多个安装孔,可使直流无刷电机和旋翼安装在机架的不同径向位置处,以此控制各个直流无刷电机和旋翼的相距间隔,从而形成一个简化的四旋翼或复合翼旋翼的布局,进而复现不同大小旋翼间距的飞行器在水气交混流场中各个旋翼之间的相互影响,实现“一台测多机”的功能,具备良好的通用性。
