Abstract

Abstract: Cabin is one of the three electromagnetic scattering sources of the fighter. Cabin Radar Cross Section (RCS) reduction is a key technology to achieve the stealth performance of whole aircraft radar of new generation fighter. Due to the stealth shape of new generation fighter, the canopy is facing challenges in stealth technology, transparency structure, bird-impact proof, ejection escape, optical performance design, and deformation control. To promote canopy performance, this paper, based on research and development of new generation fighter, studied four key technologies, including the improvement technology of canopy stealth performance, the structure design technology of large integral transparency, the simulation and optimization technology of complex surface canopy optical performance, and the deformation and state control technology of large-size movable structure. After the above key technologies research, the upgrading of canopy design technology system for new generation fighter has been completed, promoting the cross-generation upgrading of canopy performance of new generation fighter.

Key words: canopy stealth, integrative canopy, Radar Cross Section(RCS), variable thickness transparency, optical performance, deformation control
