“…Since an extensive exploration of the experimental data with focus on surface pressure measurements on the wing and flap can be found in [19], four distinct cases are considered here. For these four cases the experimental data is brought in line with the conducted CFD simulations.…”

“…In accordance with [19] the value c μ = c μ,crit represents the setting when a fully attached flap flow is just generated during power off conditions. The value c μ = c μ,max represents the maximal momentum that is deliverable by the air supply used during the experiments (see [19] for details).…”

Within the German BNF research project a generic twin-engine configuration with an active high-lift wing and modern turboprop engines is investigated. This paper deals with high fidelity RANS computations of the wind tunnel configuration measured in previous measurement campaigns. The simulation data is in good agreement with the experiment. The presented investigations focus on the jet flow due to the internally blown flap and the propeller slipstream.

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)
