Salient Features
of Liquid Propellant Rockets:
A liquid propellant propulsion system is commonly called rocket engines. It has all the hardware components and propellants necessary for its operations for producing thrust.
Liquid propellant propulsion system
Consists of one or more thrust chambers, one or more tanks to store propellants, a feed mechanism to force the propellants from the tanks into the thrust chamber, power source to furnish the energy for the feed mechanism, suitable plumbing or piping or piping to transfer the liquids,
Has a structure to transmit the thrust force, and control devices to initiate and regulate the propellant flow and thus the thrust.
In some application an engine may also include a thrust vector control system, various instrumentation and residual propellant (trapped in pipes, valves, or wetting tanks).
It does not include hardware for non-propulsive purpose, such as aerodynamic surface, guidance, or navigation equipment, or useful payload such as scientific space exploration package or missile warhead.
