mach angle造句

• In the supersonic regime the flow is dominated by wave motion at oblique angles similar to the Mach angle.
• Expansion waves are divergent because as the flow expands the value of Mach number increases, thereby decreasing the Mach angle.
• The expansion " fan " is composed of Mach waves that span from the initial Mach angle to the final Mach angle.
• The expansion " fan " is composed of Mach waves that span from the initial Mach angle to the final Mach angle.
• Mach angles may also occasionally be visualized out of their condensation in air, for example vapor cones around aircraft during transonic flight.
• When this occurs, the locus of these waves trailing behind the point creates an angle known as the Mach wave angle or Mach angle, ?
• When applying the transonic area rule, the condition that the plane defining the cross-section meets the longitudinal axis at the Mach angle ? no longer prescribes a unique plane for ? other than the 90?given by M = 1.
• For example, consider that at Mach 1.3 the angle of the Mach cone formed off the body of the aircraft will be at about ? = arcsin ( 1 / M ) = 50.3?( ? is the angle of the Mach cone, or simply Mach angle ).
