Mr. Suraj Pawar 0 Report post Posted August 15, 2017 I am trying to create propeller geometry using CAESES. I have defined non-dimensional curves for Skew, pitch, camber, camber position, chord length and maximum thickness. I have non-dimensioanlized all parameters with propeller radius.1) Is it correct or only pitch, chord length and skew needs to be non-dimensional with radius? 2)and other parameters camber, camber position and maximum thickness should be non-dimensionalized with chord length? Thank you. Share this post Link to post Share on other sites
Mr. Carsten Fuetterer 9 Report post Posted August 16, 2017 Hi Suraj, all functions should all be between normalized hub radius and 1 in the x-coordinate. Because with the blade object you will create the blade normalized (radius ==1). The y-values don't have to be normalized. Also you can refer to the propeller sample. best regards Carsten Share this post Link to post Share on other sites
Mr. Suraj Pawar 0 Report post Posted August 18, 2017 Thank you. But, when you say y- values don't have to be normalized, does that mean i shall use absolute values for parameters like pitch, skew, max. thickness? Shall I specify P/R or only P?? Share this post Link to post Share on other sites
Mr. Carsten Fuetterer 9 Report post Posted August 21, 2017 Hi Suraj, the default option for the pitch is the pitch to diameter ratio. So you have y-values around 1 and then you scale the function values by 2, because you define everything for a radius of 1.For the exact definition you can also refer to the documentation: best regards Carsten Share this post Link to post Share on other sites
