The invention provides an experimental device for testing the turning performance of a warplane nose landing gear. The device comprises a nose landing gear assembly, a torsion test assembly, an angletest assembly and a test rack assembly. In the torsion test assembly, a first end face of a second torsion sleeve is fixedly connected with a base, a second end face is fixedly connected with the lower end face of a turntable bearing outer ring, a first end face of the first torsion sleeve is fixedly connected with the upper end face of a turntable bearing inner ring, a second end face is fixedlyconnected with the lower end face of a supporting disc, and a torque meter is fixedly connected with a torsion shaft which is fixedly connected with the supporting disc. In the angle test assembly, arectangular guide rod and a guide seat are in clearance fit and are suspended out from the two ends of the guide seat, central cylindrical holes of a first baffle and a second baffle are in clearancefit with cylindrical holes of a first lug plate and a second lug plate, and the first baffle and the second baffle are fixedly connected with the upper end face and the lower end face of a cylindricalgear of the shaft gear respectively. Thus, accurate loading and accurate detection can be realized, real-time display and storage of data can be realized, and fault reverse check data can be provided.
