Water splashing test method for air intake of transport aircraft

Abstract

The invention relates to a transport aircraft inlet splash testing method for transport aircraft splash testing. According to the method, before a splash test, configuration of a test aircraft for test flight, various running statues of an engine and test aircraft glide speed point required by testing are determined according to the type of the test aircraft; materials and position of a test pool in a runway, coloring position of an aircraft body and selection of coloring materials, a video-recording method, test aircraft glide modes meeting the testing requirements and the like are determined; tests are performed one by one according to the test aircraft glide speed required by testing. The method has the advantages that splash testing is performed according to the airworthiness regulation for test aircraft, by studying, the configuration state of the test aircraft during splash testing, a building method of the test pool, coloring of the test aircraft for judging test results, a test video-recording technique, acquisition of test key data, final identification modes of data and the like are determined, and a standard set of methods and programs for transport aircraft splash testing is formed.

Description

technical field [0001] The invention is used for the water splashing test of transport aircraft, and is suitable for splashing water of civil aircraft according to the airworthiness standards of transport aircraft in Part 25 of China Civil Aviation Regulations or military transport aircraft in accordance with GJB243 "Aviation Gas Turbine Power Plant Flight Test Requirements" The test provides a basis for the compliance verification of civil aircraft or the finalization of the design of military aircraft. Splash tests of other types of aircraft can also refer to this method. Background technique [0002] The splash water test of transport aircraft is one of the important tests that must be conducted and approved for civil aircraft during airworthiness certification. At present, the civil transport aircraft in operation at home and abroad have basically completed the splash test during the type certification period, and have passed the approval of the airworthiness authority, ...

Problems solved by technology

[0003] Although the splash water test of transport aircraft is mentioned in FAA, EASA and my country's CCAR-25, it is limited to the airworthiness clauses and requirements. At present, there is no specific implementation method and technical program literature in foreign countries. It is blank, so there is no technical data and test procedures to follow
