Angle of attack as a function of Chamber line

AI Thread Summary
To calculate the angle of attack as a function of the chamber line, one must understand that 'camber' refers to the curvature of an airfoil's mean line, while 'chamber' is a different concept. The angle of zero lift can be determined through testing airfoils at various angles of attack, which is essential for understanding lift characteristics. For precise calculations, utilizing tools like the XFOIL program can help generate data on lift and drag coefficients across different angles of attack and Reynolds numbers. These calculations can be complex, but they are necessary for accurate aerodynamic analysis. Understanding these principles is crucial for effective airfoil design and performance evaluation.

Hi,
Simply my question is :
How do I calculate the angle of attack as a function of chamber line. where chamber line is given. and how can angle of attack for zero-lifr be calculated?

This is not a homework. I can't see it by my eye without knowing the lift coefficient. I hope somebody can help me out here becouse I am very tired of googling.

Thanks

'Camber' is the curvature of the mean line of an airfoil. 'Chamber' is a room, or other type of spatial enclosure.

It's not clear what you mean by angle of attack as a function of camber line.

Most airfoils are tested at varying angles of attack to determine the angle of zero lift and the angle of max. lift.
You can do lifting line or lifting surface calculations to find these angles, but these calculations are complicated to perform.
 
You can download the free "polar" program XFOIL, which will produce a chart and/or data regarding coefficient of lift and drag versus angle of attack versus Reynolds number.

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
