Problems solved by technology

Multiple sets of carriers increase the time and difficulty of design and simulation evaluation, occupy a large amount of warehouse space, and increase the cost of transportation and installation
Especially in the comparison test of engines with different structures, multiple sets of carriers bring inconvenience to placement, engine replacement, test cycle, etc., and when testing different types of engines, multiple carriers in the prior art are installed and tested separately, and individual differences in carriers are reflected In the electromagnetic scattering data of the carrier, which in turn affects the target characteristics

Abstract

The invention belongs to the technical field of engine tests, and particularly relates to a low-scattering carrier suitable for various engines. The carrier comprises a carrier upper section and a carrier lower section; the carrier upper section and the carrier lower section are both of a groove structure with the semicircular section and can be buckled together to form a cavity for containing the aero-engine. A carrier front section is arranged at the front end of the cavity and is of a conical structure, and a carrier rear section is arranged at the rear end of the cavity. The carrier rear section comprises an upper carrier rear section and a lower carrier rear section, and the other ends of the upper carrier rear section and the lower carrier rear section are connected with a carrier tail end; a carrier front section supporting frame and a carrier middle supporting frame are arranged in the cavity, and a carrier rear section supporting frame is arranged in the lower carrier rear section for supporting the aero-engine. According to the invention, great help is provided for subsequent combined electromagnetic scattering characteristic tests of various engines and test pieces, the test efficiency is effectively improved, and the test error is reduced.

Description

technical field [0001] The application belongs to the technical field of engine testing, and in particular relates to a low-scattering carrier suitable for various engines. Background technique [0002] When testing the internal electromagnetic characteristics of a cavity structure similar to an aero-engine, the direct radar test of the engine model is quite different from the installed state of the engine (the engine is placed inside the aircraft, only the nozzle parts are exposed), and the external structure has a significant impact on the radar characteristics. The test data cannot characterize the radar characteristics of the engine. Therefore, it is necessary to use low-scattering carriers to shield the external structure (to simulate the installed state of the engine) to avoid affecting the electromagnetic data. [0003] The carrier needs to meet the low-scattering characteristics of a specific angle domain, and also needs to meet the requirements of the test engine o...
