标准摘要
[中文适用范围]： GB／T 21479的本部分规定了持续可变液压可调螺距螺旋桨装置的术语和定义。 本部分适用于持续可变液压可调螺距螺旋桨装置，不适用于特定螺距下的可调螺距螺旋桨。 GB／T 21479．1规定的螺旋桨几何学词汇也适用于可调螺距螺旋桨。 [外文原描述]： This part of ISO 3715 gives terms and definitions applicable exclusively to continuously variable and hydraulic operated controllable-pitch propeller units. It does not cover controllable-pitch propeller units for which only a few specified pitch settings apply. General vocabulary for the geometry of screw propellers is given in ISO 3715-1 and is also valid for controllablepitch propellers.
