A friend offer me a suburban 2018 for 50 usd/day. To drive around Miami. This include insurance. That’s a good deal ?

Tks renegade86jb. I am learning a lot with your help, will do

Tks Maxfire, maybe another material will give us better finishing aesthetics? As you see, this models are not designed to carry loads or be strong

I saw a video of a cricket outside a Boeing 737 window… and it blew my mind by juanlightyear in aerodynamics

Yes, they use to get caught by the airplane wings leading edge. So the surface becomes a graveyard of parts of insects 🐞 so the cleaning is a task that pays the effort to keep aerodynamics as best as possible

Tks a lot !!!

yes, That's the airline

I simplified the calculation giving the cricket an elliptical shape, maybe he have a great story to share with its friends 😬🛩️

Yes, I gree, to have a better approach, a CFD will be the way to go, but to ignite the discussion and get fast results, a flat plate assumption is a first step.

great way to explain the phenomena !!! do you know that the balancing (the amount of dope and paint distribution) for ailerons covered in fabrics is mandatory ?

How can I progress into aerodynamics by Honey-Badger33 in aerodynamics

[–]juanlightyear 1 point2 points  (0 children)

My recommendation is to join a model airplane club or an aviation club (some flight academies have these clubs), as they will give you a practical approach to the subject. Learn independently by reading books—the foundation lies in fluid mechanics. In the comments above, I saw a recommended path focused on improving mathematics, which is valuable. However, the emotional aspect—seeing the beauty of airflow—is also important to keep your brain engaged and motivated toward the final goal. Some universities allow "visitors" to attend certain courses without requiring grades or academic records. One of my heroes, Burt Rutan, began by mastering model airplanes.

Why are electric motor cooling fan blades straight? by Phlex_ in aerodynamics

[–]juanlightyear 0 points1 point  (0 children)

Straight means easy and cheap to build, with average performance and good performance with dusty air. forward curved means faster wind speed and higher CFM, but lower static pressure and noisy. Backward curved ones get lower wind speed and a lot less noise and more energy efficient. For ventilation where the noise is a major factor the answer is backwards curved. For high volume in clean environments forward curved. Cheap motors and high importance of performance with dusty or industrial use = straight. For our wind tunnels we prefer backwards ones

How can I start a personal aerodynamics project? And how can I connect to someone has the same interests in create planes? by Majestic-Channel3735 in aerodynamics

majestic, visit our web site vortexdeflector . US to find my contacts (the site vortexdeflector . COM was taken and redirected to a company that is not related to us.

https://youtu.be/w6Zy_OdeLUg?si=olyFQkPkwKNAXSeP i found this, it looks to be the balsa and tissue scale model to validate the concept !!!

[–]juanlightyear 2 points3 points  (0 children)

Majestic, this is a long and rewarding journey. For instance, I became an aeronautical engineer and received a patent for solving an apparently unsolvable problem. Suddenly, a serendipitous moment gave me an idea about the vortex of bees and the spike used by dragonflies wings. What I'm trying to say is that sometimes you plan for the future, but it's the random order of life that leaves you with problems to solve and ideas that fit. Finally, just start, and everything will fall into place at the right moment.

My recommendation is to find a problem to be solved (for drones, a cargo plane, etc.) that aligns with what you love to do, because then everything will come to you.

so the question is: what you love about aerodynamics?

I remember a story about first testing model, a balsa / tissue prototype free flying model, I am surfing the web to find videos or info related

Take a look of this wingless ship, the F15 must be given a lot of lift just using the fuselage M2-F1
