Аннотация: Представлены основные результаты исследования (с использованием CFD-технологий и упрощенной авторской методики) аэродинамических характеристик экраноплана схемы «тандем» с учетом поддува и влияния струи от движителя – воздушного винта. Вычислительный эксперимент производился в программе ANSYS. Его условия предусматривали изменение кинематических параметров полета и положения экраноплана относительно экрана, скорости и угла выдува струи, углов отклонения рулевых поверхностей и элементов механизации. Анализ результатов позволяет сделать выводы об эффективности применения поддува к данной компоновочной схеме экраноплана, а также выявить основные особенности изменения ее аэродинамических характеристик при различных параметрах струи, конфигурации и положения экраноплана относительно экрана. Также рассмотрены некоторые особенности летно-технических характеристик экраноплана с учетом влияния струй от воздушного винта. Результаты работы могут быть использованы при проектировании экранопланов. Ключевые слова: экраноплан, аэродинамика экраноплана, аэродинамический поддув, динамическая воздушная подушка 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. Keywords: PAR (Power-augmented Ram), GEV (ground-effect vehicle), WIG (wing-in-ground-effect)

Wing In Ground Effect

This paper presents the numerical evaluation of ground (proximity) effects on the basic aerodynamic characteristics of a specifically designed airplane model. The ground effects were investigated in relation to the angle of attack and flight altitude. The results were referenced to the characteristics of an object in motion unaffected by ground effects.

Wing In Ground Effect

The aerodynamic characteristics of the wing-in-ground effect (WIG) craft model that has a noble configuration of a compound wing was experimentally investigated and Universiti Teknologi Malaysia (UTM) wind tunnel with and without endplates. Lift and drag forces, pitching moment coefficients, and the centre of pressure were measured with respect to the ground clearance and the wing angle of attack. The ground effect and the existence of the endplates increase the wing lift-to-drag ratio at low ground clearance. The results of this research work show new proposed design of the WIG craft with compound wing and endplates, which can clearly increase the aerodynamic efficiency without compromising the longitudinal stability. The use of WIG craft is representing an ambitious technology that will help in reducing time, effort, and money of the conventional marine transportation in the future.
