Embodiment Construction

[0017] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0018] A flying platform with a large-span S-curve intake and exhaust system includes an aircraft body 1, wings, an original aeroengine, a test chamber 4 and an aeroengine 8 for testing. The aircraft body 1 is the main body of the aircraft, and the wings include a main wing and an empennage, and the original aero-engine is arranged on the main wing. Because the test aero-engine 8 requires a special large-span S-curved air intake and exhaust system operating environment, the test cabin 4 is arranged above the aero-engine, and a support structure is provided between the test cabin 4 and the aircraft body 1. The aero-engine 8 for the test is arranged in the middle part of the test cabin 4, and the aero-engine 8...

Abstract

The invention relates to the field of aero-engine tests, and concretely relates to a flying platform with a large-span S-bend air intake and exhaust system. A test chamber is arranged above an aircraft body, an aero-engine for test is arranged in the middle of the test chamber, and an S-bend air intake duct and an S-bend exhaust system which are connected with the aero-engine for test are arranged in the test chamber. Under the condition that the structure of an aircraft is not changed, the operating environment of a large-span S-bend air inlet and exhaust system of the aero-engine for testing can be met, and the aero-engine for testing can be effectively and accurately tested during a flight test.

Description

technical field [0001] The application belongs to the field of aero-engine testing, in particular to a flying platform with a large-span S-curve intake and exhaust system. Background technique [0002] Before the newly developed aero-engine is put into service, it is necessary to carry out various tests, and correspondingly, it is necessary to build test equipment suitable for its operating environment for the aero-engine test. The background setting of the S-curve intake and exhaust system, in the ground test, the technical difficulty of arranging the operating environment is relatively small, but when it is necessary to carry out the flight test, it is limited by the capability of the existing flight platform, and it is difficult to meet the requirements. Invented aero-engine test condition requirements. [0003] The existing method for testing a newly developed aero-engine is to carry out a flight test by removing an original aero-engine and installing a newly-developed ...
