Mathematical model of the ecranoplan parameters choice at the stage of the technical offer

The mathematical model of the rational parameters choice is constructed at outline designing by a method of research of space of parameters. V alues of aerodynamic factors cy= f(a, h) and mz = f(a, h), relative coordinate of aerodynamic focus хf = f(a, h), distribution of aerodynamic loading on a bearing surface for three aerodynamic schemes of bearing surfaces plane, «duck», «hybrid» are received numerically. Functional dependences cy = f(a, h), mz = f(a, h), хf = f(a, h) are constructed.
