Evaluation of aerodynamic and flight performance characteristics of WIG with due consideration of the jet blowing from the propeller

Abstract

This paper presents the primary results of the study of the aerodynamic characteristics of a WIG with due consideration of the blow and the influence of jets from the propeller, using CFD technologies. WIG of the Tandem scheme is considered as the object of this research. The paper presents a simplified technique for modeling a jet from a propeller. The computational experiment for the study of aerodynamic characteristics was carried out in the ANSYS finite element analysis program. The conditions of the computational experiment provided for changing the kinematic parameters (position of the WIG against the screen), speed of the jet, the angle of the jet blow, and use of wing mechanization (flaps). Analysis of the results leads to conclusions on effectiveness of the blowing application to this layout of the WIG. It also allows to reveal major effects from changing its aerodynamic characteristics with various jet parameters, configuration and position of the WIG against the ground. The paper also considers some of the features of WIG flight performance taking into account the effect of jets from the propeller.
