Lynx Vawt with new airfoil rotor vanes For Plans: go to this website and scroll to the first post in the thread. I highly recommend the smaller 4'H x 3'D version seen in the video. Just adjust the dimensions. In this video you can see the increase in speed from the re-designed rotor vanes. The vanes are angled in a way you wouldn't think would work. The airfoil gains lift as the rotor spins. The airfoils are cutting a path around the turbine and lift is at a slight tangent to the axis.

Aerodynamics: Forces Acting on an Airfoil 1941 US Army Air Forces Training Film TF1-161 more at "DEPICTS THE AERODYNAMIC THEORY AND PRINCIPLES OF FORCES ACTING ON AIR FOILS." Reupload of a previously uploaded film with improved sound and video. USAAF training film TF1-161 Public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a solid object. Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with the difference being that gas dynamics applies to all gases... Overview Understanding motion of air (often called a flow field) around an object enables the calculation of forces and moments acting on the object. Typical properties calculated for a flow field include velocity, pressure, density and temperature as a function of spatial position and time. Aerodynamics allows the definition and solution of equations for the conservation of mass, momentum, and energy in air. The use of aerodynamics through mathematical ***ysis, empirical approximations, wind tunnel experimentation, and computer simulations form ...

How to make a KFm Airfoil This is how I make KFm2 airfoils for my RC planes' wings. I use 1/2 inch pink foamboard, I use this same thickness regardless of the wing chord, and put the step at half of the wing chord.
Easy Foamboard Wing Airfoil: the Basic Version Part 0 (a basic intro to the Armin Wing concept). A really quick and simple way to build an actual airfoil for an RC airplane wing. For a rectangular wing it's at least as easy to make and as strong as a KF airfoil and has the proven high-lift design approximating the "Clark-Y" airfoil used on many real and RC airplanes. Videos to follow will include improvements that take a little extra time but will make the wing more aerodynamic, water resistant, and have an integral control surface for flaps and ailerons. This is just the wing construction - overall airplane design is up to the builder!

KF Airfoil Construction Here is another attempt at making blades for my hybrid windturbine; this time using a Kline-Fogelman (KF) Airfoil. This video shows the details in the blade costruction and mounting them to the wind turbine. The blade construction went well, but the wind turbine seemed to do worse with the addition of the blades. At this point I don't know if the problem lies with the angle of attack, excessive turbine diameter, the KF airfoil or something else. Anyhow, I'm just posting this for documentation purposes.

KF airfoil and gyro findings on scratch built eurofighter Geeky RC airplane talk: I ramble on about what I recently learned from experimenting with KFm 2 and KFm 4 airfoils combined with single and dual gyros. Paul and Frank of RCFoamFighters has shared so much about what they know on RC plane scratch building that I thought it would be nice if someone else shared their findings and gave back to them. Hope you guys find the info useful. Ken

How To WIRELESSLY STREAM MUSIC IN YOUR HOME using AIRFOIL and your iPhone - Tutorial Tuesday Ever wanted to play the same song all throughout your house without having to spend a million dollars setting up a wired speaker system?

New Airfoil-Based Wind Turbine Gyro-Mill (vawt) for more information This is a preview of our new turbine. This turbine is still under development but is performing very well in initial tests. This turbine is much lighter and faster than previous turbines I've built. For one, it is a lift based turbine utilizing symmetrical airfoils rather than a drag based turbine such as the Savonius. This has both advantages and disadvantages. This turbine really goes, but the Savonius starts up easier in super light winds. The airfoils were designed using open source design software and fabricated with composite materials for light weight. This wind turbine also uses sealed bearings and requires no oiling or regular maintenance.
