Rocketry is heavier than air flight. I submit we discovered it before lighter than air flight. I will hazard that I do have a nice understanding of how it works

Rocketry is heavier than air flight. I submit we discovered it before lighter than air flight. I will hazard that I do have a nice understanding of how it works. I learned it from media like this:

I do think you’re dead wrong!
- dreamcompiler 5y agoThe common connotation of "heavier-than-air flight" and "lighter-than-air flight" is that air is the medium in which the flight takes place, and that air is essential for the flight to happen. The science of aerodynamics is necessary for describing how such flight works. That's not true for rockets. Rockets can fly in air, and a rocket's fins only work in air, but rockets don't have to use fins and rockets work fine in the vacuum of space. Because air is mostly irrelevant to rockets -- and rockets [in space at least] fly by principles that have nothing to do with aerodynamics -- rockets are not typically included in discussions of how "heavier-than-air flight" works.
- tdy721 5y agoTechnically correct. Hey it’s only mostly flight until max Q, then it’s... spaceflight? Star Wars ships come out of space backwards and I don’t get it...
- JasonFruit 5y agoMany people would object that rockets don't fly, they are hurled.
- perryizgr8 5y agoA hurled object would decelerate from the moment it is thrown. Its fastest speed is at launch. Rockets have their slowest speed at launch, and they continuously accelerate. So they are definitely not "hurled".
- tdy721 5y agoDisagree. It could be seen as one very long hurl? Or you know, stages of them?
