| 摘要： | An aircraft penetrating heavy rain can be affected aerodynamically in at least four ways (1) raindrops striking the fuselage and wings of the aircraft impart a downward momentum to the aircraft (2) increased aircraft drag results from the aircraft striking the raindrops head on (3) at any instant of time the aircraft will contain a thin layer of water over most of its surfaces which will give additional mass to the aircraft and (4) the water on the airfoil will result in a roughened airfoil surface that could produce significant aerodynamic penalties. An order of magnitude calculation was made for the penalty associated with the factors one two and three. The roughness factor required detailed modeling and boundary layer calculations and was studied using the 'aerodynamic effects of frost model'. The results achieved on each of the penalty factors are described and the factors most likely to cause significant performance degradation are indicated. |
