compression lift造句

"compression lift"是什么意思   

例句與造句

  1. The Boeing X-51 ( WaveRider ) also uses compression lift.
  2. The compression lift decreased the induced drag of the XB-70 about 30 %.
  3. With the wingtips drooped downwards, the compression lift shock wave would be further trapped under the wings.
  4. "Waverider " refers in general to aircraft that take advantage of compression lift produced by their own shock waves.
  5. Most of the lift was generated by the fuselage by compression lift . The " wings " were small fins providing trim and control.
  6. It's difficult to find compression lift in a sentence. 用compression lift造句挺難的
  7. Higher speed designs using compression lift, waveriders, remain an interesting possibility for hypersonic vehicle designs, although only testbed models have been flown.
  8. The basic concept of compression lift is well known; " planing " boats reduce drag by " surfing " on their own bow wake in exactly the same fashion.
  9. The XB-70 used compression lift, which arose from a shock wave generated by the sharp leading edge of the central engine intake pressure field behind the strong shock wave.
  10. This increased the aircraft's directional stability at supersonic speeds, shifted the center of lift to a more favorable position at high speeds, and strengthened the compression lift effect.
  11. At high speeds the outer 20 feet of each wing folded down to improve compression lift, although to a much lower angle than the B-70's 75-degree droop.
  12. By lowering the outer panels of the wings at high Mach numbers, they were able to take advantage of compression lift on the underside of the aircraft . This improved the L / D ratio by about 30 %.
  13. To date the only potential production aircraft that used compression lift has been the XB-70 in the 1960s, although with the cancellation of the program after only two prototypes had been built, it ended up being a testbed only.
  14. The B-70 had a shoulder-mounted wing to best use compression lift generated by the nose and engine intakes, but this was not suitable for a transport where the fuselage is best situated above the wing for better visibility and easier loading.
  15. The channel formed between the tail fins is intended to augment vehicle down force at speeds in excess of Mach 1 by taking advantage of a phenomenon called compression lift . To generate compression lift, air is forced outwards by a center body, in this case the tunnel on top of the vehicle housing the rocket propellant feed lines, against two vertical aerodynamic surfaces.
