常見例句雙語例句Blade element theory was used to calculate unsteady aerodynamic loads in linear and nonlinear regimes.槳葉氣動力計算采用時域非定常空氣動力計算模型，包括非線性分離和動態(tài)失速的影響。In the model, the modified blade element analysis theory is used to model the rotor, and the modified momentum theory is used to calculate the induced velocity.其中旋翼模型采用改進了的葉元法，旋翼誘導(dǎo)速度計算采用改進了的動量法。The approach of blade-element theory is opposite that of momentum theory since it is concerned with the forces produced by the blades as a result of the motion of the fluid.葉片元素理論的方法與動量原理的方法相反，因為它關(guān)注的是由流體運動導(dǎo)致葉片產(chǎn)生的力。 返回 blade element theory
