Build Your Own Freaking Fast FlightGear PC

Building your own PC

I’ve debated whether it is worth posting an article about building your own PC. Anyone who’s a serious builder can come up with something that fits their budget and performance requirements better than I can. Anyone who’s not a serious PC builder might be better off not messing around with the idea. It’s easy to get yourself into trouble and ruin parts if you don’t know a little bit about what you are doing.  On the other hand, it isn’t that hard, and the end result can be a great system for minimum cost.

Real-time UAS Simulation and Visualization

Real-time UAS Simulation and Visualization

In previous posts I’ve described the process of carefully modelling the basic geometry and mass properties of a UAS in YASim to provide a real time flight dynamics simulation of the aircraft in FlightGear.  I also described how we carefully modelled the blended body shape of our UAS using airfoil plots and spline curves.  These curves were then imported into MoI and used as the basis to generate a smooth, flowing, organic surface shape.  MoI is able to export the model as a 3d triangle mesh in a variety of formats including 3ds.

3D Modelling with MoI

3D Modelling with MoI

MoI (Moment of Inspiration) is a really interesting 3d modelling tool.  There are two things that separate it from other tools in my view.

1. It has a very simple and intuitive interface.

2. It has powerful and intuitive primatives for drawing and manipulating curves and 3d surfaces. For example MoI allows you to define 2d (or even 3d) curves and then stretch a 3d curved surface between your curved lines–possibly with additional guide curves to control the shape.  Like with any tool, it takes a little thought, practice, and planning to break down the structure …

Physics Modelling

Dynamics (Physics) Modelling and Flight Simulation

There are many great tools available to help engineers design and develop new aircraft and flight control systems.  One such tool is the flight simulator.  More specifically: an open source flight simulation such as FlightGear. Being open-source FlightGear is flexible and adaptable and can be used to solve or explore new scenarios that a proprietary software applications may never have anticipated.

FlightGear + YASim

Here I describe the process of modelling a flying wing in FlightGear using the built in “YASim” physics engine.

A brief word on yasim (wiki documentation): YASim …
