The present invention discloses a flow fixture for the air cooling flow test on hollow blades, which comprises a fixture body with an opening on one side thereof. The fixture body is provided with a fixture inner cavity used for the levitation of a hollow blade and communicated with the outside through the opening, a seal gasket covered onto the outer surface of he hollow blade and closed inside the opening of the fixture inner cavity, and a fixture air inlet for being connected with a flow tester and feeding the cooling air into the fixture inner cavity. The tenon air inlet of the hollow blade and the lower margin plate of the hollow blade are positioned in the fixture inner cavity. The shrouded air outlet of the hollow blade is positioned inside the fixture inner cavity to be communicated with the outside, so that a flow channel for the cooling air is formed, wherein the cooling air flows into the flow channel through the fixture air inlet and flows out of the flow channel through the ...
