A launch vehicle is a complex system conceived to deliver a payload to a given orbit by providing the right altitude and velocity for orbit injection. This has to be achieved at the mimumum launch cost possible and with the maximum reliability and overall quality of launch service.

Launchers are usually composed of several stages to optimise the payload mass to be delivered to orbit.

The main elements of a launcher are:

  • the rocket propulsion system (liquid or solid) required to provide the thrust to reach orbit
  • the structural elements needed to contain the propellant tanks and the payload and sustain all the loads (quasi-static, dynamic, thermal, acoustic and shock) encountered during its mission
  • the guidance, navigation and control systems required to follow an established trajectory
  • the various electrical sub-systems

 

Europe’s guaranteed access to space relies on a mix of launchers and their evolutions. 

New and innovative research and technology ensures that Europe examines possible future configurations of expendable launchers as well as the system concepts and technology needed for a reusable launcher vehicle.
