The invention discloses a shock wave tunnel for a hypersonic air vehicle ground simulation test. The shock wave tunnel for the hypersonic air vehicle ground simulation test mainly comprises a gas power piston formation section (1), a driving section (2), a driven section (3), a transition section (4), a spray pipe section (5) and a test section (6), wherein the gas power piston formation section (1), the driving section (2) and the driven section (3) are arranged inside the shock wave tunnel, and the transition section (4), the spray pipe section (5) and the test section (6) are arranged outside the shock wave tunnel. An inner diameter section of the driving section is a uniform section segment, and inner diameter sections of the driven section and the transition section are both from-big-to-small variable cross-section segments. The gas power piston formation section is located on the tail portion of the shock wave tunnel, and a plurality of gas power pistons (13) are evenly distributed inside the gas power piston formation section. The driving section is located between the gas power piston formation section and the driven section. The transition section is connected between driven section and the spray pipe section, and a seal membrane is connected between the transition section and a connection flange of the spray pipe section. The test section is located in front of the spray pipe section. According to the shock wave tunnel for the hypersonic air vehicle ground simulation test, due to the fact that the shock wave tunnel which is jointly driven by detonation and pressurization is adopted, the tests of the hypersonic air vehicle aerodynamic performance and the engine reliability are achieved, the energy usage ratio is improved, the test cost is lowered, and the test period is shortened.
