Équation des gaz parfaits. Elle aide les ingénieurs à calculer la poussée ?
It’s been a while since we tested you with a tough question. We’ll give a bonus point to those of you who can tell us at what point this equation is important for our engineers.

Rockets use gases as fuel, the high pressure of the gases means a higher temperature and that means that they are expelled with higher kinetic energy, that's the way they get the needed speed

Yes. This equation is very important for rocket engineering. The mass flow rate of fuel, fuel efficiency, total fuel mass all are correlated..the equation is used for flow rate control.

Ideal gas equation, applies when the gas is compressible e.g. at the high velocities in a rocket engine nozzle, and is used everywhere in nozzle design equations...

Used to calculate nozzle exit pressure and therefore pressure thrust Used to nozzle exit temperature and therefore momentum thrust (via stagnation temperature equations)
