座舱是战斗机三大电磁散射源之一，座舱盖雷达散射截面（RCS）的减缩技术是实现新一代战斗机全机雷达隐身性能的关键技术。基于新一代战斗机隐身外形平台，座舱盖在隐身技术、透明件结构、抗鸟撞、弹射救生、光学性能、结构变形控制等领域均面临新的挑战。本文以新一代战斗机为背景，研究了座舱盖性能提升的4项关键技术：座舱盖隐身性能提升技术、大型整体座舱盖透明件结构设计技术、复杂曲面座舱盖光学性能仿真优化技术、大尺寸活动部件变形及状态控制技术。经过上述关键技术研究，完成了新一代战斗机座舱盖设计技术体系的升级，促进了新一代战斗机座舱盖技术和性能的跨代提升。
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.
