Abstract
The invention relates to a bent-tail type fixing device for a model test, comprising an alpha angle servo mechanism, a beta angle servo mechanism and a gamma angle servo mechanism, wherein the alpha angle servo mechanism is at the middle part, the beta angle servo mechanism is at the tail part and the gamma angle servo mechanism is at the head part. Three sets of servo systems are distributed on a same axial line and controlled by respective independent servo system; and the attitude adjustment of the alpha, beta and gamma angles are realized through the monitoring of an angle encoder; therefore, the angle adjustment of the alpha, beta and gamma angles of a model are realized. The center line of a model connection shaft (14) is parallel to the X axis and has a certain distance from the X axis, so that the specific environmental test requirement is met.
