Sometimes I just wonder why the Linux people just can't install one computer to run Windows? And why do the Linux people copy everything from Windows? Claim 1: Because Windows is bad. Claim 2: Simply not true. By the way, in addition to Linux, I use Mac. I am typing this from iMac. Why would I install Windows on some computer? I am not that rich, I have lots of better uses for money. For example for getting the Snow Leopard and iLife I can run about all software I need on the combination of the Mac and Linux, and I do all the gaming on a Playstation 3 so I don't care about Windows games. I run X-plane of course on Linux and Mac. Mac is more flexible because it doesn't suffer from multiple OpenGL context problem and I can run two OpenGL programs the plane maker and the sim at the same time. To sum, there is very little if any use for Windows OS in any use.

Consumer drones multicopters are cheap and work great, but flying Fixed-wings is much more fun to fly. My most recent efforts are towards longer range FPV. The video transmission equipment never seems to work as well as advertised but some antenna boosters have helped. These are some images from earlier projects and restorations, I will add later projects and descriptions in a while. About Work.

For any object moving through a fluid, forces are applied to the object as the fluid moves around it. A fluid can be something like water, or even something like the air around us. When the object is specifically designed to maximize the forces that the fluid can apply, you can designate these designs as airfoils. A more common name that most people would use is a wing. The shape of a wing, or airfoil, determines the forces that are applied to it when it moves through a fluid or the air. These forces also depend on the speed of motion through the fluid and the direction of flow around the airfoil. With all of these parameters, how can you design airfoils? How do you optimize airfoils for a particular use?

XFLR5 includes the xfoil program for foil analysis, and several 3d analysis methods for planes : - a non-linear lifting line method for standalone wings - two vortex-lattice and a 3d panel method for the analysis of aerodynamic performance of wings and plane operating at low Reynolds numbers The latest v6 version introduces stability analysis of planes.

The XLFR5 prediction shows about the same Cd change at high Cl values, but not at all the clearly bigger change at low Cl values, which are the most important ones to sailing. Patent Locking SwingArm. Depending on speed, AoA changes, etc, it is often advantageous to cut the TE off sharp and form a "bound" closed vortex flow which fills in the streamlines generating an "apparent" cord length and a smoother seperation point. Post by salvatoreone » Sun May 23, am. This link isn't about keel trailing edges, it's about prop nozzle trailing edges. I would think you could capture the vorticies with a much smaller computing time, but not as accurately. Second, do not expect aero data to be replicated by hydro data when it comes to sharp trailing edges. DAT foil file by changing the file extension to. The large drag increase around zero AoA is almost certainly due to unsteady vortex shedding which occurs with a sufficiently large blunt TE. Gareth Thomas on 4 Oct Search MathWorks.

Incremented the format of the project file to Cp instead of q. S instead of F.

I have never seen them unless there is free surface, cavitation or compressibility effects. I hope I haven't over promised and the all of this will be ready by August About Work. It was better to use overall fine grid and wall functions than a one with fine grid at the walls for the low reynolds number model. Search MathWorks. Instrument Acoustics. I am not that rich, I have lots of better uses for money. The large drag increase around zero AoA is almost certainly due to unsteady vortex shedding which occurs with a sufficiently large blunt TE. Post a Comment. Start Hunting! Patent Gear Reduction, Double Worm. In addition, we've taken an even better step that merely creating a XLFR5 degenerate model. At the time of writing this, the 4.
