The propellants get pressurized to press them into the pipes to the rocket engines. It's operation can best be described as a really large spray dose. This job is done by the propellant utilization system. The more mass getting ejected (This property is called mass flow) or the faster this mass gets ejected (called average exhaust velocity or specific impulse), the more velocity the rocket gains.įor ejecting mass every second, this propellant mass also has to be delivered from the tanks inside the rocket to the engines every second. The impulse of this mass is compensated with the remaining rocket accelerating. Every second, the rocket ejects propellant mass through the nozzle of the rocket engine. The concept is plain conservation of impulse (or Newtons third law).
Why explain so much for a simple rocket, which could like anything in Orbiter? Because it gives the rockets character, and this makes them look more realistic, than a simple bald cylinder with a conical rocket engine at the end.Ī rocket gains velocity by ejecting mass through a rocket engine. Keep that in mind when looking at a rocket or designing one. See also Rocket and Rocket engine for more detailsįirst some explanation what a rocket actually is.Ī rocket is a machine which ejects mass for generating velocity. It is not about designing the rocket for a special mission, just experimentation.
We will start with a some basics to know about what a rocket is, create a simple single staged rocket and later add a second stage as final step.
ORBITER ADDONS FOR BUILDING ROCKETS HOW TO
This tutorial aims at explaining how to create a simple rocket for Orbiter by using Anim8or and configuration files or Multistage.dll.
