Design of hailstone ingestion test scheme of turbofan engine
In order to meet the requirements of hailstone ingestion test verification for domestic turbo-fan engines and obtain effective hailstone ingestion capability verification,according to the relevant re-quirements of hailstone ingestion test in GJB241A-2010 and CCAR-33R2 standards,the design method of hailstone ingestion test scheme of turbofan engine was studied,and the experience of the design pro-cess was summarized.Based on the analysis of the connotation of standards related to hailstone inges-tion tests and practical application scenarios,the design methods of the test parameters,such as hail-stone quantity,hailstone speed,engine working state,and impact position were studied.By studying the hailstone projection scheme in relevant foreign tests,the design and evaluation method of the hailstone projection scheme was determined and the corresponding simulation analysis method was defined.The test scheme designed according to the method was verified on a certain engine,which can provide refer-ence and guidance for the design of the hailstone ingestion test scheme of the turbofan engine.
