In today's episode of @FreeCADNews Friday, a glipse into part of our aircraft's final aerodynamic refinement- wing root fairings.
If folks want, we can drop an entry into the forum showing how we did it...let us know!
To give full context on this, we are working out flaps for the Phoenix S-LSA under development. Not done yet. This particular result reflects 30° down, projected max gross weight at sea level. Well inside the 61 knot Vs0 limit under @FAANews MOSAIC.
A seminal book on the study of drag. Our two copies in the office are used daily.
Sadly, our engineering team never knew of this book's existence until they had moved on from academia decades ago and entered the workforce.
Can anybody in academia explain?
Red tape is a burden on industries and aviation is no exception. That’s why @USDOT and @FAANews are reforming MOSAIC, removing outdated regulations while keeping safety front and center 🇺🇸
Ever seen an integral that looks scary but breaks down beautifully?
Try this one:
∫ tan⁻¹(√[(1 − cos 2x) / (1 + cos 2x)]) dx
👀 Looks complex? Wait till you see the trick!

Thanks to the new Assembly WB in @FreeCADNews , the development of the Phoenix's retractable landing gear is going smoothly, allowing us to iterate accurately & quickly.
In fact, we ran a 'v0.1' gear on the OML and did a first CFD simulation earlier today!
FreeCAD rocks!
Why Derivative of x² is 2x?
Ever wondered why the derivative of x² is 2x, or why the derivative of log x is 1/x? Eminem and Trump break it down using simple numbers, making calculus fun and intuitive! Watch how a small change in x reveals the magic of derivatives.
Note : This…
Since we haven't posted anything of much substance lately, how about an early render of the Phoenix's shape? She has evolved greatly since; this took us a few hours with @FreeCADNews , then was put through the paces in the OpenFOAM environment!
Much work on the Phoenix this weekend. Found some more efficiency gains that will also make other areas of the aircraft easier to manufacture, assemble and maintain.
It is a lot of work, work that now has us seeing double 😉!!
A major component of aircraft design is powerplant selection, evaluating a variety of capabilities & limitations against mission requirements.
The Phoenix project just passed that milestone.
Welcome aboard, @BRP_Rotax !

To anyone paying attention, Elon's blow up today shouldn't have come as a surprise.
Case and point, H-1B visas.
When conservatives showed the slightest bit of disagreement with him he told them to f*ck themselves, declared war on them, and then threatened to have them…
