发动机叶片的喉道面积是发动机装配,调试的重要参数,喉道面积的测量是叶片装配的关键,叶片通道是由76个叶片的上下缘板和每两个叶片叶身型面之间构成的空间曲面通道,研究设计的喉道面积测具能准确地检测每个通道窗口间规定截面的通道宽度尺寸和上下缘板的通道高度尺寸计算出叶片的喉道面积。喉道面积的流量与发动机的推力有关,是影响发动机性能的重要因素,叶片喉道面积测具保证叶片通道排气量均匀。
The throat area of the engine blade is an important parameter for engine assembly and commissioning. The throat area measurement is the key to the blade assembly. The blade passage is formed by the upper and lower edge plates of 76 blades and the blade surface of every two blades Spatial curved channel, the throat area design of the study designed to accurately detect each channel between the window of the specified cross-section of the channel width size and height of the upper and lower edge of the channel height to calculate the blade throat area. Throat area flow and engine thrust, is an important factor affecting the engine performance, blade throat area measurement to ensure that the vane channel exhaust volume uniformity.
