Implementation of the panel method to the solution of flow around aircraft
Journal Title: INCAS BULLETIN - Year 2015, Vol 7, Issue 2
Abstract
In this study a panel method is used as a numerical technique for the solution of the potential three dimensional flows about a complete aircraft configuration to determine the aerodynamic characteristics. This approach seems to be more economic, from the computational point of view than methods that solve the flow field in the whole fluid volume such as finite difference, finite element or finite volume techniques. A system of source and doublet distributions is implemented and Dirichlet boundary conditions are applied. A computer program using Matlab is developed. Firstly flow over three dimensional swept wings is solved and the results are compared with experimental data to validate the numerical panel code. After the ideas have been discussed a sample calculations around complete aircraft are presented to illustrate the gain of using panel method technique.

The analysis of the process tending towards equilibrium in transitional and turbulent wall flows
Starting from the integro-differential formulation (IDF) [1], [2] of the basic conservation equations in wall flows, the authors perform a qualitative analysis of the microscopic-macroscopic domain. According to IDF, the...
Horizontal Flight Dynamics Simulations using a Simplified Airplane Model and Considering Wind Perturbation
An in-house method of Newton-Euler inverse dynamics guidance based on a simplified airplane model in horizontal flight was proposed in a previous paper presented at NMAS 2018 workshop [1]. The goal was to guide the airpl...
A Practical Method to Estimate the Aerodynamic Coefficients of a Small-Scale Paramotor
There are few aircraft other than lighter-than-air vehicles that have the payload carrying capability, short field take-off, and slow speed ranges afforded by a powered parafoil. One very interesting aspect of the powere...
