Research on the design method of arch corrector based on Haack conformal dome

Abstract

The Haack curve has the lowest air drag under a given condition. However, the Haack conformal dome has the most difficult non-axisymmetric dynamic aberration to correct. There is almost no research on the aberration correction method of the Haack conformal dome. The traditional fixed corrector has low design freedom and limited correction ability. Therefore, a pair of aspheric equations for non-axisymmetric systems are derived in this paper. A non-rotationally symmetric corrector with high design freedom is calculated. The simulation results show that the design method in this paper can correct the aberrations of conformal optical systems well. The problem of difficulty in solving the initial structure of the arch corrector is solved. It provides an important method for aberration correction of ogive conformal dome. The research on the aberration correction method of the Haack conformal dome solves the contradictory needs of superior aerodynamic performance and high imaging quality, which is of great significance to developing conformal optical systems.
