Liquid Propulsion (LPS) Subcommittee
Technical Objectives
The charter of the Liquid Propulsion Subcommittee addresses technical problems and issues of greatest national needs associated with liquid engine systems. Topics include technology, components and engines of main propulsion, divert and attitude control, reaction control and post boost systems applied to tactical, ballistic missile defense and strategic, engines for, small launch vehicles, hybrid engines, and access to space propulsion.
Scope
Liquid propulsion technology issues examined include overall engine system, thrust chamber assembly components, and propellant feed systems. Component issues that may be examined include liquid engine systems such as thruster assembly and thrust vector control; liquid combustion elements such as the thrust chamber and gas generator/preburner; and liquid propellant feed systems such as turbomachinery, lines, ducts, valves, tanks, and pressurization systems. Fuel types include liquids, slurries, gels, endothermics, and cryogenics. Characterization of system and component performance is done through analysis, modeling and simulation, and engine testing validation.
- Liquid Engine System
- System Analysis & Trades – Industry accepted codes including design trade methods, cost
models, upper stage design tools, model validation methods and criteria. Power balance
codes, modeling of hydrostatic bearings and trans analysis were identified of particular
interest - Health Management & Controls – Instrumentation standards, pre-launch engine operations
and control systems - Test – Component, engine and integrated propulsion/vehicle best test practices, life and
qualification testing - Advanced Materials – Development of materials, manufacturing, applications and test
methods - Liquid Combustion Associated with Engine Subsystems and Components
- Thrust Chambers Assembly
- Propellants and Fuels (liquids, slurries, gels, endothermics, and cryogenics)
- Liquid Propellant Feed and Pressurization Systems
- Turbomachinery
- Feed/Pressurization Systems – lines, ducts, valves, and tankage
- Tactical Liquid and Gel Propulsion Systems
