Research on conformal fairing technology

Because the conformal optical technology can obviously improve the aerodynamic performance of the infrared guidance missile,it has been studied deeply in recent years.By comparing the performance of the missiles with conformal fairing and conventional missiles,the advantages of the conformal optical technology are demonstrated in the maneuverability and stealth of the missile.The difficult problems of conformal optical field are discussed.For removing the aberration of conformal fairing with the change of scanning field,several design schemes are introduced in detail,including fixed corrector,counter-rotating phase plate,deformable mirror and so on.The advantages and the disadvantages of each scheme are discussed,and the processing and test of the conformal optical parts are introduced briefly.Finally,it is outlooked for the future of the conformal optical technology.
