Combustion chamber temperature field analysis and adjustment method

Abstract

The invention discloses a combustion chamber temperature field analysis and adjustment method. The method comprises the following steps: data input: converting basic data, flow data and test result data of a combustion chamber test into an associated data set for storage; data screening: performing data judgment by utilizing basic data, flow data and test result data in the stored data, and screening out qualified data and unqualified data; data analysis: forming data image information from the screened unqualified data, further analyzing the data, and judging the unqualified data; data output: outputting an adjustment scheme to guide on-site operation; and the operator tests again according to the adjustment scheme. According to the method, unqualified data can be accurately analyzed andjudged, complexity and low efficiency of manual judgment are reduced, the one-time repair success rate of the combustion chamber is increased, the temperature field adjusting method can be accumulatedand stored, references and bases are provided for later temperature field adjustment, and workers who need to be replaced later can also take over the temperature field adjusting method quickly.

Description

technical field [0001] The invention relates to a temperature field data adjustment technology, in particular to a combustion chamber temperature field analysis and adjustment method. Background technique [0002] In order to ensure the safe and reliable operation of the aero-engine turbine rotor blades, it is required that the average temperature of the gas along the radius must be distributed according to a certain law, so that the entire rotor blades are close to equal strength. When overhauling the engine combustion chamber, it is necessary to determine whether the temperature distribution of the combustion chamber meets the requirements for use. When the temperature field test is unqualified, the workload of judging the temperature field of the combustion chamber through the test data is large. At present, due to the lack of tools, it is often only manually calculated and judged by repair technicians. The impact of the combustion chamber is also relatively large, and i...
