The utility model discloses a one-way rupture diaphragm valve for an attitude control engine and the attitude control engine. The diaphragm valve comprises a valve body, a diaphragm and a supporting piece, the valve body is provided with a flow channel in the first direction, the membrane is arranged in the flow channel, and the edge of the membrane is connected with the inner wall of the flow channel so as to isolate media on the two sides of the membrane. The supporting piece is provided with an open hole penetrating through the two main surfaces of the supporting piece. Facilitating upstream media into downstream, the diaphragm structure is simple in structure and reasonable in design, the supporting piece is closely arranged on one side of the diaphragm, the edge of the supporting piece is connected with the inner wall of the flow channel so as to provide support when a downstream medium on the side of the diaphragm applies reverse pressure to the diaphragm, and compared with the prior art, the diaphragm
