Details
The Atlas test stand is LPL’s primary feed system, designed to support liquid rocket engine development, throttle system development, and validation campaigns. The stand is configured for Jet-A/LOx propellants, operates at a maximum expected operating pressure (MEOP) of 1500 psig, and supports total mass flow rates up to 12 kg/s.
The test stand features a two-part modular structure separating the GN₂ pressurant system from the propellant storage and feed systems. This architecture enables efficient transportation to and from the RRS Mojave test site, supporting a high testing cadence. The system includes 6-gallon propellant tanks (with planned upgrades to ~17.5 gallons), ½" pressurant lines, and 1" propellant feed lines. Engine specific flow control is achieved using two dome-loaded regulators.
Instrumentation and data acquisition systems provide real-time measurement of critical parameters, supporting detailed test stand, throttle, and engine performance characterization. The system includes 4 pressure indicators, 14 pressure transducers, 2 differential pressure transducers, 5 thermocouples, and 2 turbine flow meters. Additionally the stand incorporates a diffuser for the cryogenic propellant tank, an independent GN₂ purge system, and pressure relief safety devices throughout.
Safety and operational reliability are central to the Atlas design. The system is capable of remote operation, automated aborts, and continuous monitoring of pressure, temperature, and flow conditions to ensure safe handling of high-pressure commodities.The Atlas test stand expands LPL’s testing capabilities, enabling efficient and repeatable engine and throttle development.
