The first term is used in aeronautical engineering to determine the lift-to-drag ratio. The second refers to engine efficiency (same as for launchers). 1/2pic.twitter.com/ydg8eRus8A

It’s time for our traditional end-of-month equation. We’re keen to see if our space tweeps can tell us what this formula, this month’s theme and Ariane rockets have in common. #ArianeGrouppic.twitter.com/gbefBhy6YB

And the third part is the structural coefficient (the mass of a structure divided by mass+propellant). Hey, who said rocket science was simple?

it must be an equation for speed. The specific impulse and t are expressed in seconds, multiplied by g produces a result u in metes per second.

Go into the keyboard settings and add Greek as a language that you can switch between and you can type Δv

On dirait bien la vitesse d’un lanceur à un instant t considérant l’impulsion spécifique de son moteur, sa masse au décollage et sa masse à l’instant t...
