A Practical Method for Investigation of Aerodynamic and Longitudinal Static Stability of Wing-in-Ground Effect
The purpose of this paper is to present a fast, economical and practical method for mathematical modeling of aerodynamic characteristics of rectangular wing-in-ground effect (WIG). Reynolds averaged Navier-Stokes (RANS) equations were converted to Bernoulli equation by reasonable assumptions. Also Helmbold's equation was developed for calculation of the slope of wing lift coefficient in ground ...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
study of wing shapes influence on mav aerodynamic coefficients
in recent years, design of small aircrafts are studied and extensively developed. one of the most important of these aircrafts is micro aerial vehicles (mavs). as part of aerodynamic design of mavs, the wing design is important. in fact, the main part of this design is to find an appropriate shape for the wing. in this work, influence of the wing shape at low reynolds number flow is investigate...
full textPrediction of Aerodynamic Coefficients Using Neural Networks for Sparse Data
A reliable and fast method of predicting complex aerodynamic coefficients for flight simulation is presented using neural networks. The training data for the neural network is derived from numerical simulations and wind-tunnel experiments. The aerodynamic coefficients are modeled as functions of the flow characteristics and the control surfaces of the vehicle. The basic coefficients of lift, dr...
full textModel of Unsteady Aerodynamic Coefficients of a Delta Wing Aircraft at High Angles of Attack
Several approaches for modelling the longitudinal aerodynamic coefficients of a fighter aircraft at high angles of attack, including the unsteady effects are presented. A traditional approach where the model of the coefficient arises in the form of the steady and unsteady effects, the unsteady effect being modelled by means of transfer functions. The second approach uses an internal variable de...
