Due to the smaller Angle of injection, the ratio of total pressure loss of aerodynamic ramp is less than the physical ramp and transverse injection stream.
由于喷流方向与主流方向夹角较小,总压损失也较物理斜坡、横向喷流等混合增强方式小。

Local strain concentration in angle-ply lay caused by transverse crack of circular lay in composite pressure vessel was studied by means of advanced shear-lag method.
High tooth gear has small module, small pressureAngle, and large addendum to enlarge the transverse contact ratio, improve gear strength, and reduce the noise.
