英语词汇“lift coefficient”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

lift coefficient n. Aerodynamics a ratio representing the lift developed by unit area of an aerofoil in relation to the air speed, and defined as the lift divided by the product of the aerofoil area (in plan) and the square of the air speed (and, in modern use, by half the air density also).

lift coefficient1919

1919 H. Shaw Text-bk. Aeronaut. iii. 39 As the angle of incidence increases the lift coefficient also increases rapidly, until an angle of about 13° is reached, beyond which the coefficient increases less rapidly, and reaches its maximum value in the neighbourhood of 15°.

1933 Techn. Rep. U.S. Nat. Advisory Comm. Aeronaut. No. 463. 18 As speeds above half the velocity of sound are exceeded..the flow breaks down as shown by a drop in the lift coefficient.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) I. 85/2 The maximum lift coefficient (the stall value) of the wing is 1·1–1·5.
