Slender body structure supporting and resistance reducing device under action of follow-up thrust

The invention discloses a slender body structure supporting and resistance reducing device under the action of follow-up thrust. The device comprises a supporting frame mechanism fixed by a bottom plate, a glass plate fixed above the supporting frame mechanism and a hoop universal ball mechanism installed below the slender body structure and a solid rocket engine. The device for the ground test of the slender body structure under the action of the follow-up thrust can effectively support the slender body structure and the solid rocket engine, and effectively reduce the frictional resistance between the slender body and the solid rocket engine and the support frame in the swinging process. 本发明公开了一种随动推力作用下细长体结构支撑及减阻装置，所述装置包括：由底板固定的支撑架机构、固定在所述支撑架机构上方的玻璃板以及安装在细长体结构及固体火箭发动机下方的抱箍万向球机构。本发明公开的用于随动推力作用下细长体结构地面试验的装置，能够对细长体结构及固体火箭发动机起到有效支撑、并有效减小细长体及固体火箭发动机摆动过程中与支撑架之间的摩擦阻力。
