Aeroelastic Optimization of the High Aspect Ratio Wing with Aileron

Abstract

In aircraft wings, aileron mass parameter presents a tremendous effect on the velocity and frequency of the flutter problem. For that purpose, we present the optimization of a composite design wing with an aileron, using machine-learning approach. Mass properties and its distribution have a great influence on the multi-variate optimization procedure, based on speed and frequency of flutter. First, flutter speed was obtained to estimate aileron impact. Additionally mass-equilibrated and other features were investigated. It can deduced that changing the position and mass properties of the aileron are tangible following the speed and frequency of the wing flutter. Based on the proposed optimization method, the best position of the aileron is determined for the composite wing to postpone flutter instability and decrease the existed stress. The represented coupled aero-structural model is emerged from subsonic aerodynamics model, which has been developed using the panel method in multidimensional space. The structural modeling has been conducted by finite element method, using the p-k method. The fluid -structure equations are solved and the results are extracted.

Edge Blending to Enhance the Flow Over Double delta wing configuration during re-entry

“…This will give the static temperature. Now further to find speed of object and speed of sound we use the below empirical relationships Velocity of Sound = a=(YRT) 1/2 (6) and Mach number = M= C/a = Object Speed /Speed of Sound (7) Shock-shock interactions are considered for investigating the aerodynamic heating of wings, initial methods were to use the basic relations of pressure and heat in order to obtain aerodynamic heating but not applicable to complex geometry [5]. To obtain the flow deflections, the below relation is used from the oblique-shock interactions that is given by L. Laguarda [6] in its research as :-…”

“…To determine the viscous drag reduction from riblets, three different methods were applied; the first approach is skin friction balance to directly measure the wall shear stress; the second approach is 2D boundary layer momentum integral [MI] and third approach is internal strain gauge balance [6]. Mohammad Ghalandari, Ibhrahim Mahariq, Farad Ghadak and Fahad Jarad described briefly the aileron mass parameter has an adverse effect on velocity and frequency of flutter issues [7]. Fluttering is the self-vibrations occurring at varying speeds, is considered to be most common problem, which can ultimately lead to structure failure if proper damping system is absent.…”

Thermal conductivity improvement in a green building with Nano insulations using machine learning methods

“…Based on the Genetic Algorithm (GA) and Machine Learning model, a Multi-disciplinary design optimization (MDO) method is introduced to represent the best efficient layers of insulation for the buildings (Ghalandari et al, 2022;Mohebian and Riahi, 2019;Zhang et al, 2022). The CO 2 effects which is emerged from the building's energy consumption and the gas production from building materials preparation, as an environmental influence is considered (Akan and Akan, 2022).…”

“…The results of the studies proved that energy saving through the insulations method can create effective influences on the constructions industries (Gustavsson and Piccardo, 2022;Aydin and Biyikoğlu, 2021). Nowadays, the application of machine learning algorithms and optimization methods are remarkable in the engineering problems (Ghalandari et al, 2019(Ghalandari et al, , 2022. Abdou et al (2021) highlighted the thermo-economic phenomenon by representing the optimal thickness of advanced material in the insulation of Green Buildings using Multi-Disciplinary Optimization Method (MDO).…”
