Abstract

The invention discloses a method and system for authenticating safety of alternative fuel in an aircraft engine. The method includes the steps of obtaining key safety parameters related to safety of an engine system on the basis of historical experience data of aircraft fuel and structure characteristics of the aircraft engine, building the mapping relation between the aircraft fuel and a key safety parameter space of the engine system, obtaining a work area of the key safety parameter space of the engine system using the alternative fuel by means of the mapping relation, and classifying the key safety parameters of the engine system through sensitivity analysis to obtain a test condition of the key safety parameters. Therefore, a safety boundary of the key safety parameters of the engine system based on the aircraft fuel is obtained according to a large amount of historical experience to serve as a judgment standard, so safety of the area of the key safety parameters of the engine system using the alternative fuel can be judged. On the basis that fuel cost and time cost of the authentication process are reduced, the test condition and acceptance criteria needed by the alternative aircraft fuel are provided.

Description

technical field [0001] The invention relates to the interdisciplinary fields of alternative energy, aviation safety and airworthiness technology, in particular to a method and system for authenticating the safety of alternative fuels in aero-engines. Background technique [0002] The development of aviation alternative fuels, especially renewable bio-based fuels, is an important guarantee for realizing diversified aviation energy supply and ensuring national energy security. In addition, global climate change has also proposed new goals for the air transport industry. The realization of this goal cannot be achieved only by reducing the weight and performance of aero-engines and aircraft, and must rely on biomass aviation alternative fuels. [0003] For the aviation fuel market, "ready-to-use" fuels are promising because their use does not require structural changes to aero engines, aircraft, and infrastructure. The American Society for Testing and Materials has published th...
