    Abstract
  • Improved cost-efficiency ratio is a major factor considered in the development of trainer aircraft. Operational analysis was introduced as a method for evaluating training effectiveness of trainer aircraft. Approaches to the engineering estimation of aerodynamic characteristics for aircraft with double-delta wings configuration were studied and the procedures for determining aircraft performance indices were formulated. Then, taking training effectiveness as an objective function, through numerical method for multivariate optimization, the conceptual design optimization selection of a certain advanced trainer aircraft with double-delta wings configuration was accomplished under the constrains of tactical and technical requirements and interrelated geometry. Agreement of a calculation example with engineering practice indicates that the optimal design has higher training effectiveness than the baseline design, in addition to improve structural force-bearing conditions.
