(Pressure patterns at different angle-of-attacks (red shaded regions indicate positive pressure relative to atmosphere, blue shaded regions indicate negative pressure relative to atmosphere, image from )īesides using Bernoulli’s principles (which accounts for conservation of energy), Newton’s principles (conservation of momentum), Euler’s equations (conservation of mass, momentum, and energy), and Navier-Stokes equations (all of the above plus viscosity) must also be dealt with in order to fully understand the generation of lift.Ī good article that provides a good, brief introduction to these principles is available on NASA’s website here:įor more detailed, technical explanations regarding lift, please visit the following websites: (Velocity field around a wing, image from )Īdditionally, the image below illustrates, using pressure patterns, that the angle-of-attack indeed has profound effects on the lift that's generated. They never recombine (the image below illustrates this fact). The truth is, the top-side air travels significantly faster than the bottom-side air. Well, if this is the case, then we would have a really, really tough time trying to explain how airplanes fly upside down: The popularly-known explanation (as seen in K-6 textbooks) involves mis-applying Bernoulli’s principle by stating that high-pressure, low-velocity air on the bottom-side of the airfoil and low-pressure, high-velocity air on the top-side, which recombines at the trailing edge of the airfoil at the same time, regardless of angle-of-attack, is the sole mechanism by which lift is generated. There has been much discussion with regards to how and why airfoils really work. But to be honest the Hexagon3D model has a lot more detail.What is an airfoil, and how does it work:Īn airfoil is a body (such as an airplane wing or helicopter blade) designed to provide a desired reaction force when in motion relative to the surrounding air. Which is about 1/10 the time it took me to model in the Ford flathead V8 in Hexagon3D. I need to add some more details like a fan belt, alternator, starter, spark plug wires & oil filter.
And I used a 1/6 diecast scale model of a 1930s to early 1950s Ford flathead V8 as reference which is sets on a shelf in my computer room among near 80 other diecast models of cars (mostly vintage) of varying scales from 1/24, - 1/8th & 1/6th. The previously V8 engine I modeled was doing completely in Hexagon3D. And influenced by the 1960s Chrysler Hemi and the the Ford Boss 429 of the late 1960s & early 1970s. Using beta 4.9.44 I thought I would like to model a V8 engine completely in the voxel room. I decided to kill my afternoon with 3DCoat. A 1960 Corvette which I restored in 1983 and still own.
After this morning's yard work (tearing up dead bushes, raking leaves), visiting my Mother's gravsite and going to the grocery store I was too tired to actually replace the fuel lines on my own antique car.
