Rocket Engines burn
liquid fuel in the presence of liquid oxidizer to generate large
amounts of thrust. This section provides an overview of many
of the world's rocket engines, which are used to power historical
or existing launch vehicles (either reusable or expendable - see RLV's
and ELV's). The
thrust range of the engines presented here ranges from 10,000 lbf
(44 kN) to 1,600,000 lbf (7,040 kN) and use many different
combinations of fuel and oxidizer.
Rocket engines differ
from rocket motors in the rocket engines burn liquid fuel while
rocket motors burn solid fuel.
