Software developers: I am begging you to put representative screenshots on the home page. This has become a real widespread problem. I know you want to tell us all about the amazing (sincerely!) stuff under the hood, but to users, the interface is the product.

I also like it when there's a short video that shows how the thing works and what it can do.

Sadly they don't teach Show Don't Tell in the lectures

Is there a similar drone design simulator?

idk off hand but i'm sure there's something like OpenRocket for R/C airplanes. Where you put in the dimensions, wing type, mass distribution, and other stuff and it tells you if it's aerodynamically stable or not. After that you put in an ardupilot autopilot+gps+airspeed sensor and there's your drone. iirc, with ardupilot you can do automated flight planning like "fly to this gps coordinate, orbit for 10 minutes, fly…

You describe https://flow5.tech/flow5.html (Im not directly familiar, but it is an extension of xflr5 which I have used). Gives you the lift/drag/moment curves, and stability coefficients of a fixed wing drone/rc airplane

There is a game on Steam where you can design and fly your own aircraft. Would be fun to then try to 3d print the successful ones. But I can't remember the name of the game, sorry.

Kerbal Space Program?

Does anyone know of something similar, but for aircraft and/or drones? I’ve been 3D printing model aircraft with my 8-year old but would be great to take it to the next level.

I read the name and the first logical thought that came to mind was that of a platform to have AI agents iterating on rockets design. How doomed am I?

Just reading the name I wouldn't have been surprised if it had nothing to do with rockets whatsoever - I was half expecting it to be some kind of "agentic platform to accelerate your product development" etc. I think I need to go for a walk.

That was also my first thought...... :D

What do they hold, exactly? Leaders are dead and keeps dying, good chunk of their military is defunkt, while "mightiest human forces" don't even have boots on ground.

No, _I_ highly recommend you to open a few foreign newspapers and lurk in foreign (to whom?) forums, groups, &c. you're either misinformed or blind, based on these bullet points.

Stop reading r/iran or CNN or whatever bs you pump into your brain.

This war sucks but it's very far from "Iran is holding".

We used OpenRocket for designing our rocket for UK youth rocketry competition UKROC[1]. It is great for getting a 'spherical cow in a vaccuum' idea of likely altitude with different motors, centre of pressure, center of mass etc. But it obviously doesn't take account of detailed aerodynamics etc and we found the maximum altitude estimates were about 15% too high. But it was still very useful. [1] UKROC is an amazing…

> we found the maximum altitude estimates were about 15% too high.

this often happens when the wrong rocket finish is selected. Everyone chooses a polished finish when in actuality they've just sprayed the thing with paint.

Skin drag is real.

The strait of hormuz is still closed, and a new government has not been installed. From a conventional perspective Iran is by all means "losing" the war. However, the United States and the majority of the world desperately want the strait to be opened and have so far been unsuccessful in preventing Iran from blocking it. The US is also greatly interested in regime change, which has also been unsuccessful.

> The US is also greatly interested in regime change

Trump doesn't car about regime change. Just like in Venezuela, his plan is to kill leaders until there's one that can make a "deal" (whatever it means).

Thanks for the suggestion, I've added it to our home page.
