ABSTRACT

The problem of constructing the forebody of a supersonic flying vehicle with the integrated intake of a jet engine is considered in a two-dimensional formulation. Multi-objective optimization is performed for the purpose of minimizing the aerodynamic drag and pitching moment under the constraint of a constant lift force. Based on the method of local linearization of the relationship between the gas-dynamic functions and the geometric parameters, an analytical solution to the problem is obtained. The aerodynamic characteristics of the forebodies are compared with the results of numerical simulations within the framework of the Euler equations.
