At the middle of the 20Th<\/sup> century the testing tools and methods used to measure the airflow through and over the various components<\/em>of aircraft engine were traditionally mechanical. In the late 1950\u2019s arose some problems, while appeared that traditional mechanical testing tools using to measure and adjust the nozzles would no longer fit onto the part, and didn\u2019t provide repeatable and accurate test results, cause of nozzle warped so badly during engine testing<\/p>\n

When gas turbine engines are manufactured, overhauled, repaired or rebuilt, it is critically important to be able to measure the airflow through and over the various components<\/em>of the engine to insure proper operation. Such measurements are made primarily on the nozzles and turbine vanes. A gas turbine is a rotary engine that extracts energy from a flow of combustion gas. It has an upstream compressor coupled to a downstream turbine, and a combustion chamber in between.\u00a0Energy is added to the gas stream in the combustor, where air is mixed with fuel and ignited. Combustion increases the temperature, velocity and volume of the gas flow. This is directed through a nozzle over the turbine’s blades, spinning the turbine and powering the compressor. Energy is extracted in the form of shaft power, compressed air and thrust, in any combination, and used to power aircraft, trains, ships, generators, and even tanks.<\/p>\n
