例句與造句

1. When the Typhoon was dived at speeds of over 500 mph ( 805 km / h ), the drag rise caused buffeting and trim changes.
2. Wing sweep has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance.
3. This was because the thickness / chord ratio could be reduced closer to the tips, balancing this against the sweep reduction in postponement of Mach effects such as buffeting and drag rise.
4. Although the Typhoon was expected to achieve over 400 mph ( 644 km / h ) in level flight at 20, 000 ft, the thick wings created a large drag rise and prevented higher speeds than the 410 mph at achieved in tests.
5. The design was used in airplanes as a way of greatly reducing the sharp drag rise that occurs at transonic speeds; its utilization often results in a pinch-waisted fuselage shape that National Advisory Committee for Aeronautics ( NACA ) labeled the design principle'area rule,'and variously identified as coke bottle, wasp waist, or Marilyn Monroe shape.
6. It's difficult to find drag rise in a sentence. 用drag rise造句挺難的
