The invention discloses a high-pressure jet flow force measuring device for a wind tunnel test. The high-pressure jet flow force measuring device comprises a base, a box type balance, an attack angle cushion block, an abdomen support, a test model, a flexible joint, a model upper cover, a pressure sensor and a jet flow opening, wherein the top of the base is connected with one end of the box type balance; the other end of the box type balance is connected with the bottom of the attack angle cushion block; the top of the attack angle cushion block is connected with one end of the abdomen support; the other end of the abdomen support is connected with the test model; one end of the flexible joint is communicated with a ventilation pipeline of the abdomen support; the other end of the flexible joint is connected with one end of the jet flow port, and the other end of the jet flow port is connected with the inner wall of the tail end of the test model; the pressure sensor is arranged on the jet flow opening; and the model upper cover is connected with a top opening of the test model. The problem that a high-pressure gas source jet flow system and a balance measurement system interfere with each other is solved, the pressure precision of jet flow gas is improved, and meanwhile the device is simple in structure and convenient to machine.
