Abstract

The invention discloses a measurement device and measurement method of an exhaust area of a single-guide vane, and belongs to the technical field of aeroengine detection. A single guide vane exhaust area measurement device comprises a base, a fixed device and a simulation device which are arranged on the base; the fixed device comprises a first positioning module and a second positioning module arranged at two ends of the base; the simulation module comprises a first backside blade simulation block and a second backside blade simulation block arranged at one side of the base, and a first basinside blade simulation block, a second basin side blade simulation block, a large edge plate simulation block and a small edge plate simulation block which are arranged at the other side of the base.An exhaust area value of single to-be-measured blade can be obtained through measurement, the blades of which the total exhaust area value is in accordance with the requirement of a design drawing canbe selected from the blades through screening and matching the blades, thereby effectively reducing the assembly and measurement times of the guide blades and finally realizing one-time assembly.

Description

technical field [0001] The invention relates to the technical field of aero-engine detection, in particular to a measuring device and a measuring method for the exhaust area of ​​a single guide vane. Background technique [0002] The exhaust area is an important parameter of the engine. During the assembly process of the guide casing assembly, the digital exhaust area measuring tool is used to measure the measurement points specified in the design drawing between adjacent guide vanes. From the first group of guide vanes to the last group, calculate all the measurement data according to the formula to get the total exhaust area value, compare it with the theoretical area specified in the design document, and judge whether it is within the tolerance range. Determine eligibility. If it is unqualified, replace the blade according to the situation that the total area value is too large or too small, then measure the area value between the replacement blades, replace the old data...
