Problems solved by technology

Once the component is isolated from the body, the edge and embedded structure of the component will be exposed. If the component is tested without any treatment, the scattering of the edge and embedded structure will affect the test accuracy of the component.

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0021] The inventor of the present invention considers that after the overall stealth profile design of the aircraft is completed, the stealth performance test of each component will be considered. Once the component is isolated from the body, the edge and embedded structure of the component will be exposed. If the component is tested without any treatment, the scattering of the edge and embedded structure will affect the test accuracy of the component. Therefore...

Abstract

The invention discloses a low-scattering carrier used for an RCS test. The low-scattering carrier used for the RCS test comprises an upper surface and a lower surface, wherein the lower surface is a smooth curved surface; the upper surface is a plane and in seamless connection with the lower surface; a flange connector is arranged at the middle of the upper surface and used for installing a part to be subjected to the RCS test. According to the low-scattering carrier used for the RCS test, the low-scattering carrier is designed to be integrated with the to-be-tested part in structure, the smooth close connection is realized, scattering of the edge of the part is eliminated, the cavity structure of the part is also shielded, the actual loading status of the part is better simulated, and thus the part can be subjected to RCS measurement assessment more accurately.

Description

technical field [0001] The invention relates to the field of electromagnetic scattering measurement, in particular to a low-scattering carrier used for RCS testing. Background technique [0002] After the overall stealth shape design of the aircraft is completed, the stealth performance test of each component will be considered. Once the component is isolated from the body, the edge and embedded structure of the component will be exposed. If the component is tested without any treatment, the scattering of the edge and embedded structure will affect the test accuracy of the component. [0003] Therefore, there is a need for a low-scattering carrier capable of eliminating component edge scattering and shielding the internal cavity structure of the component to solve the above problems. Contents of the invention [0004] The invention provides a low-scattering carrier for RCS (Radar Cross Section, radar cross-section) testing, which is designed in an integrated structure wit...
