Building South Korea’s Very Own Rocket
KARI needed a sophisticated high-level rocket engine test facility (RETF) solution that enabled safe remote control for engine testing, prompt troubleshooting, and emergency response to achieve the requirements for engine control.
Four 75-ton engines (first stage), a single 75-ton engine (second stage), and a 7-ton engine (third stage) had to be mounted onto the Nuri rocket with a total of six engines to power it for successful lift-off. Faced with these requirements, KARI selected Rockwell Automation Korea, which delivers the engineering capabilities needed as well as excellent reliability for control solutions.
We deployed a control system to KARI’s small-scale test facility and pursued the development and testing of the RETF over a decade together with researchers from KARI, leveraging the knowledge and experiences of Korean engineers and domestically developed programs for a liquid rocket engine test.
Rockwell Automation Korea participated in building the RETF for the Nuri project as a solution provider and engineering partner from April 2012 to July 2022 across four major phases:
- Phase 1: Combustor and turbo pump testing facility
- Phase 2: Three-stage engine combustion testing facility
- Phase 3: Engine combustion test facility for ground and high-altitude conditions
- Phase 4: Propulsion system testing facility
Rockwell Automation Korea supported multiple simulations by deploying process control, human machine interface (HMI), data (FactoryTalk Historian Site Edition (SE), FactoryTalk Historian Machine Edition (ME)), Asset (FactoryTalk AssetCentre), production monitoring and control, and quality management systems, for agile data analysis, storage time and capacity.
Distributed control systems (DCS), which include ControlLogix programmable automation controllers (PAC) Redundancy System, Stratix network switches with devised level ring (DLR) modules, FactoryTalk Server & Client, FactoryTalk Historian, FactoryTalk AssetCentre, process book reporting and time synchronization module (1756HP-Time) were applied.
Rockwell Automation Korea’s engineers designed and built a control system and developed a highly dependable program for liquid rocket engine combustion testing. As testing facilities were distant from the control tower, control and instrumentation (C&I) was established to remotely conduct and monitor combustion tests. We introduced an emergency stop system and offered maintenance/repair services to enable stable operation of the control system by simulating unexpected contingencies and diverse combustion situations.
