Abstract

The embodiment of the invention discloses an elastic gust response wind tunnel test device, which comprises wings, an adapter piece, a wing connecting piece and a test supporting piece, and is characterized in that the test supporting piece comprises a guide rail, supporting bases arranged at the two ends of the guide rail respectively, and a sliding assembly nested on the guide rail. The wings comprise a left wing and a right wing which are symmetrically arranged; the adapter piece comprises a left wing adapting piece and a right wing adapting piece; the left wing is arranged at one side of the wing connecting piece through the left wing adapting piece, and the right wing is arranged at the other side of the wing connecting piece through the right wing adapting piece, the wing connectingpieces and the adapting pieces are connected to the outer portion of the sliding assembly in a sleeving mode; and the wings are driven to move through sliding of the sliding assembly in the axial direction of the guide rail. According to the embodiment of the invention, the problems that an existing gust response model in a rigid model form cannot simulate the elasticity condition in a gust response test, the model support mode is single, and gust response tests under various boundary conditions cannot be met are solved.

Description

technical field [0001] The present application relates to but is not limited to the technical field of aeroelasticity test, especially an elastic gust response wind tunnel test device. Background technique [0002] During the flight (especially for large aircraft), when encountering gusts of wind during the flight, the aircraft will produce a large response, which will bring safety hazards to the aircraft structure and passengers. Significance. [0003] Since the current gust response model is mainly a rigid model, and the elastic deformation of large aircraft is large during flight, the above rigid model does not consider the elastic effect; and the support method of the model is single, which cannot meet the gust response test under various boundary conditions. Contents of the invention [0004] In order to solve the above technical problems, the embodiment of the present invention provides an elastic gust response wind tunnel test device to solve the existing rigid mod...
