    When asked if they were open, Leonardo replied, “Only on the small ship.” He described the door as aircraft-like in that it was hinged on the inside and opened inward, its thickness being between 3 and 4 inches, as was the exposed dome’s wall area around the door closure, which he thought appeared to be pressurized with an inflating seal, both on the door and the door jam area.

If the second or third method is used, a strong air flow is produced so that the method cannot be used if a delicate object is present in the air flow. To solve these problems, we considered the method using the acoustic radiation force of an aerial ultrasonic wave. United States.

The singularity method (panels) in (c) is used to determine subsonic and supersonic linear flow conditions. The Euler method in (d) is to reproduce non-linear flow conditions in the transonic regime.
