There is a mistake in this tutorial video at (7:32): optimizing the twist for the optimal cl/cd should be set to 0 degrees. QBlade automaticaly detects at wich AoA the cl/cd is optimal and uses that AoA when this option is selected. Putting a number other than zero in the box behind it changes the AoA by that amount away from the ideal AoA. This is an option in case youre ideal cl/cd is at an AoA too close to the stall angle
Thanks for your correction sir! I will definitely try to correct it.
Thank you very much! It was kinda hard to find a tutorial about Qblade. Your tutorial video is very helpful for beginner to get a grasp on this software. :D Looking forward to your structural and flow analysis!
+Andy Wee I have already uploaded the videos for structural and wake mesh. I am glad that it helped. 😊
Dear please if you are good with VAWT Design , Kindly contact me on whatsApp 00201138775550 Eng, Samir
Nice series of videos. Thanks mate!
Thanks for your nice comments 😊
Your video is very good.explains more about the graphics and what each one means
Thanks for your feedback! I will definitely try to do so😊
Does qblade optimize the chord length automatically, or should this be done in a separate program using the outputs from qblade?
Hello! Sadly it doesn’t optimise chord length. One suggestion would be to optimise and then model it using qblade for results. Optimisation is a tedious work though! I understand.
Thank you very much for this instructive video.but would you please explain how you changed the chord in the first and second line .you changed them to lower chord, by which logical you have used ? once again thank you
Thanks for the question! The reason being a requirement of stronger hub and have an equal force distribution throughout the span of the blade. Hope this answers the logic
It is a great tutorial series! I just have a question for now, how can I save the DAT file? I'm using the Airfoil tools database but I do not know how to save the file in the format .DAT. Could anyone help me with this? Thank you all!
I hope you might have found the “source dat file “ as a link. Right click on that select “save target as” then you can save it as .dat in your drive. Hope this helps.
Thanks for such a wonderful tutorial. I would like to know if we could import the 3d design to solidworks.
Yes! The model can be exported in stl format and can be imported into solidwork with settings to import as surface and edit the stl
Thanks for your reply. I realized that I can't edit the design obtained in stl format. Hence I tried to export the blade design as co-ordinates. While I tried to export it into solidworks, it shows the error as "at least two adjacent points are identical or too close". How should I proceed further?
Thanks again.
but how can the twist be negative? I'm getting the same result and the Cp is not very good...
Hello sir! If you are referring to the example that’s just for a demonstration of how this code can be utilised. The iteration on the geometric twist can be eased by choosing an optimised baseline haw turbine blade design.
You should optimise the twist for opt. cl/cd and fill in 0 degrees in the box (see my comment above) This will change the twist to the correct one
Hi, Is it possible to use different cross-section other than the NACA airfoil provided in the software ?
Absolutely!
@@write2sijovarghese what if the airfoil is multi-element ?
multi element in 2D? I am not sure if I have come across such situation. If possible send me a screenshot. I will look into the same.
how to change the unit from cm to m in blade design
Hi thanks for the question and sorry for the late response, I ll get back with the answer asap.
if we want to study on hydrofoil and propeller, is it we can use this software too?
Wonderful question sir, as far as qblade is concerned it deals only with Horizonal axis and vertical axis wind turbine propeller blades. For hydrofoils and aircraft/ship propellers you can use ansys/icem cfd, which has dynamic meshing options too. Where you can go for FSI, fluid structure interaction.
How can I attain the dimensions to produce my blade in Solid Works?
If I understood your query correctly ; after producing the blade in qblade you need to export it in stl which can be imported into solidworks and probably use the ruler to measure dimensions roughly . If you just need the dimensions to create the blade from scratch then the parameters should be calculated manually.
Where can i get the file sd7962
Hi it’s from airfoil tools (dot) com website where after you find the required airfoil and there will be an option to save the coordinates as .dat. Let me know if you have additional queries.
How can I change the working fluid here
Hi as far as I know we cannot change the working fluid here. If there is a way to change the viscosity that might kind of help.
hey has sb knowledge about Jblade? its a derivitive of this program combined with xflr5 but im having troubles with it
Hello Sir, I was not aware of this derivative. Thanks for the information. I will look at how Can I help.
@@write2sijovarghese informative video btw i like it !
Hi I am trying to look at Jblade when ever I am getting time. May I know if you went through the references section ?
@@write2sijovarghese i was busy so i overflew too fast, also im now abroad for a month so i cant look up futher but thx for your response anyway! greatly apreciated! i like to use and play around with programs like this im.just not very good at it.
Thanks for your nice comment. yes playing around with the tool will greatly help! happy learning.
How about blade pitch?
Hello sir, can you be more specific?
what is happening at 2:38 ?
Thanks for your question! That is the plot between the flight characteristics to the chord length of the airfoil. I hope it is clear.
no no my question was about your adjusting of "A-" .
please xplain the tuning thing ...

plz change the voice
Thanks for your honest opinion.
@Sijo Varghese what did u use to get that voice. Like any software or ......
A software named balabolka, for which one can download different realistic voices.
