A method for technology evaluation and selection of aircraft survivability design

LI Shou-an1,SONG Bi-feng1,LI Dong-xia1,WANG Qing-feng2(1.School of Aeronautics,Northwestern Polytechnical University,Xi'an 710072,China;2.No.94106 Unit of PLA,Xi'an 710600,China)  
The objective of this paper is to develop a method used to evaluate and select design technologies for aircraft survivability enhancement.The evaluation criteria for aircraft survivability are proposed from the two aspects of susceptibility and vulnerability,and the effects of aircraft survivability technologies on the evaluation criteria are analyzed in a technology impact matrix.The bargaining weight method is proposed to calculate the weighting factors of the evaluation criteria,and the impact matrix is used to evaluate the effects of survivability technologies on aircraft survivability enhancement.Considering that the survivability improvement is obtained at the cost of increasing weight and expense,a new concept,the survivability obtained with unit cost and unit weight is proposed to evaluate and select the technologies.The evaluation and selecting process is analyzed through a practical example.
