Abstract: A viewing gyro window includes a fixed ring, a shaft assembly, and a rotating member. The fixed ring is secured with a transparent plate and installed on the transparent panel. The fixed ring has an annular groove and a gas inlet. The shaft assembly is assembled to the center of the transparent plate and is pivoted to a rotating shaft via a bearing. The rotating member has a ring fastened to the periphery of a rotating plate. A linkage member is fastened to the center of the rotating plate and secured with the rotating shaft. T he rotating member is in no contact with the fixed ring. The ring has plates arranged annularly and extending toward the annular groove. High pressure gas enters into the annular groove to drive the plates to rotate the rotating member.

Abstract: A viewing gyro window includes a fixing housing, an air-transmitting element, a center bracket, a first driving element having multiple first plates, a second driving element having multiple second plates, and a transparent element attached on the first driving element and the second driving element. A first tunnel and a second tunnel are defined on the center bracket, and are linked through a tube. When the first plates and the second plates are driven by air from the air-transmitting element emitted out of the first tunnel and the second tunnel via the tube, the first driving element and the second driving element rotate simultaneously. Because the transparent element is attached on the first driving element and the second driving element, simultaneous rotations of the first driving element and the second driving element increase a torque and angular velocity of the transparent element so as to accelerate its rotation speed.
