thank you. what a beautiful tutorial for a beautiful program.

Great method!

La matrice 2×2 peut être considérée comme matrice tridiagonale ?

😑 take your damn time bro

I love uuuu man so much

Nice job you Sir,

GOAT

I can't get the notepad data on a separate notepad. it only appears in the programs.. anyone who knows how to activate this with this program?

I've been struggling with the blending problem for 2 semesters, thank you for the video!

Worst experience ever

Thank you!

How to connect the xfoil with notepad for automation can you please tell me?

I am thinking GUPPY! 😱😁🤪🤣👍👍🇺🇸

But, these vehicles don't look like Blue Origin or SpaceX, ... that's VTVL! 😱😁🤪🤣👍👍🇺🇸

Quadcopter, ... Bicopter will do ya! 😱😁🤪🤣👍👍🇺🇸

😁👍👍🇺🇸

OWWW! Did not see that coming! 😱🤣👍👍🇺🇸 We can build back bigger and better! 🤣👍👍🇺🇸

I might have to go back to ssssscool! 😁👍👍🇺🇸

WHAT! These are student rockets, they have to learn to build their own motors! 😱😁🤪🤣👍👍🇺🇸

Now that's a "SOONER SCHOONER"! 😁👍👍🇺🇸

Was it actively stabilized or thinking it was a fish?! 😱😁🤪🤣👍👍🇺🇸

WOAH! We be WOBBLY! 😱😁🤪🤣👍👍🇺🇸

Sooooo, ... it makes moe betta wocket! 😱😁🤪🤣👍👍🇺🇸

Thank you for this video Doctor Hays. I have designed a small UAV for surveillance applications and was wondering which approach to use in structural skeleton design. Very much appreciated 🙏🏽

Hello, a total long shot but throwing it out there. I'm trying to duplicate an old fiberglass fuselage (40" long). I only have plans showing a side profile view and top view but need to identify a series of cross-section profiles (lofting?) to use in carving a mold plug. I've been trying many searches to see if there is software that can help creating the 3rd view cross-sections from the 2 existing views. I don't understand it, but came across your videos of Solidworks and was encouraged that maybe what I need is possible. I'm not explaining this well, but if you receive this comment and understand my question, I'd be very grateful to know if I'm looking for something that can't be done? Thank you! JGiles

you're video just made me look good at work. thank you!

how to include the L/D ratio in the pacc file as it doesnt include this parameter

I encountered an issue called "convergence failed" for viscous calculations. Airfoil is RAF 25. How can I resolve that?

I have been strugling with designing a nice wing-fuselage blend and damn it can be frustrating. I have been using the same method and tried different ones too.

This is so good dude -- make another one of these showing a full analysis of a wing, or showing advanced techniques!

Good evening Dr. Hayes, I was just asking, can you help me and create a solid works video on structural analysis of an aircraft structure

Respected Dr. Hays; my Xfoil software is not displaying Cd values. Can you suggest me a solution.

awesome! very helpful !

At 14:45 you mention there's some GUI's that go over Xfoil making it easier to make polars, etc. Would you mind sharing some insight into those? Curious what they are and how they function. Thanks and awesome tutorial otherwise.

Nice, would the results be more accurate if done with say ansys fluent or openfoam over solidworks cfd add on ?

Better use CATIA

Haha, I like your merciful words at the end! Any thoughts on Prandtl's non-elliptical lift distribution theory?

Thank you.

Book looks nice

Thank you for the video, it's very helpful! But I have one question, I'm pretty new at this stuff so if it's a stupid question, I'm sorry in advance :) When I follow your instructions, just three columns with values show up in the end, is there any setting on how to add a column for drag coefficient C_D which doesn't show up? Thank you!

Hi friend, how to de-rotate airfoil please ? green line is not aligned with TR et LD edge for me. I have tried the command dero, but it doesn't work, do you have an idea how to use it, please?

What if I would like to obtain airfoil coordinates from the drawing??

Excellent tutorial. Cheers.

Got it!

Very interesting. I don't know why more of these have been built. A very interesting design. Thank you Dr. Hays for sharing this with the club meeting. 73 de kb5hxt

Hi Dr. Hays, I am trying to run Xfoil on my laptop using a linux sub system and am getting this error to do with fonts: Error of failed request: BadName (named color or font does not exist) Major opcode of failed request: 45 (X_OpenFont) Serial number of failed request: 26 Current serial number in output stream: 28 I don't suppose you know the solution to this? Thanks, Freya

Nice. Way to harness that huge N motor. 100+ pounds going supersonic. Awesome. Now try it with a minimum diameter rocket!

Hello Dr. Hays, thank you for sharing this useful technic. I have a question though, can we implement different Mach numbers in this software? I see it is fixed at Mach 0. Thanks again...

good job Dr. what is the name of the book ?
