BS ISO 17540:2016 pdf download.Space systems — Liquid rocket engines and test stands — Terms and definitions
1 Scope
The International Standard provides terms and definitions in scope of design, testing, reliability analysis and quality control of liquid rocket engines. The terms are required for use in all types of documentation and literature including in the scope of standardization or using the results of this activity.
2 Terms and definitions
2.1 General
2.1.1 rocket engine
RE
reaction engine producing thrust for vehicle movement with the help of substances and energy sources contained within the vehicle being moved
2.1.2 liquid rocket engine
LRE rocket engine (2.1.1) using propellants in liquid form
2.1.3 low-thrust engine
LTE
rocket engine (2.1.1) of a thrust not more than 5 000 N
2.1.4 liquid rocket propulsion system
propulsion system including engine, propellant tanks, avionics for control sub-systems, pressure vessels and control devices for pneumatic and hydraulic control sub-systems, propellant feed system,actuators for steering sub-systems, and auxiliary equipment
2.1.5 clustered engine
liquid rocket propulsion system (2.1.4) consisting of multiple rocket engines (2.1.1), common propellant tanks, and autonomous (independent) propellant feed systems
2.2 Engine units
2.2.1 chamber
engine assembly where propellant and/or gas generation products, as a result of chemical reactions,are converted into products of combustion, created at the expiration of the reactive force
2.2.2 turbo-pump
TP
engine component designed to pump propellant into the chamber (2.2.1), gas generator sets and automatic engine
2.2.3 booster turbo-pump
BTP
turbo-pump (2.2.2) engine support designed to increase propellant pressure in the pipelines to pump (2.20.1)
2.2.4 gas generator
unit of engine wherein propellant, as a result of chemical reaction, is converted in gaseous products of reaction at relatively low temperature
2.2.5 automatic engine controller
engine assembly designed for automatic control, regulation or maintenance of engine
2.3 Engine types by way of work process
2.3.1 engine with afterburning
engine where gas generation products after their use are used to drive the turbo-pump (2.2.2) assembly
2.3.2 engine without afterburning
engine where gas generation products after their use to drive the turbo-pump (2.2.2) assembly are released into the environment
Note 1 to entry: Engine without afterburning have a pump (2.20.1) or a pressurized fuel supply.
2.3.3 single-mode engine
engine with one major mode
2.3.4 multimode engine
engine with several basic modes
2.4 Engine types by multiplicity of use and integration
2.4.1 expendable engine
engine intended for a specific purpose and used only one time
2.4.2 nonexpendable engine
engine intended for a specific purpose and used multiple times
2.4.3 single-start engine
engine started only once for a specific purpose
2.4.4 multi-start engine
restartable engine
engine started multiple times for one specific purpose
2.5 Engine types by purpose
2.5.1 main engine
engine intended to accelerate the space vehicle
