The invention belongs to the technical field of dynamic wind tunnel tests of hypersonic aircrafts, and discloses a pitching and rolling two-degree-of-freedom wind tunnel dynamic test device based on air bearing support. The dynamic test device adopts a structure with a balance in the front, and a pitching and rolling two-degree-of-freedom adjusting mechanism is positioned on a central axis; the rolling shaft automatic locking mechanism and the rolling shaft angular displacement measuring device are fixedly installed on the rolling shaft. The pitch axis automatic locking mechanism and the pitch axis angular displacement measuring device are fixedly mounted on the pitch axis; the pitching bearing bush and the rolling shaft bush are air bearings. The dynamic test device has the characteristics of simple structure, compact size, high rigidity, small size and large bearing capacity, can adjust postures of two degrees of freedom of rolling and pitching, and is automatically locked and unlocked through a locking dev
