ROCKET PROPULSION ELEMENTS
The book’s cover shows a typical separation of a payload stage or satellite from
an upper stage of a space flight vehicle in the vacuum of space. There are two
rocketpropulsionsystems.Theliquidpropellantrocketengineontheupperstage
(on the lower left) has just lifted the satellite into space and has just been shut
down. The reaction control system on the payload stage has four small inclined
thrusters, which can be seen during their firing operation; they are moving the
payload away from the expended upper stage. A small thruster’s plume (flame)
has a bright, elliptically shaped, hot gas, very small core, which is visible. The
hot exhaust gases disperse from this core in all directions, and this part of the
plume is almost invisible.
