Cold flow test systems are critical systems used in the development of liquid-fueled spacecraft to enhance the reliability of the engine. In these systems, no ignition is performed; instead, critical components such as the engine, tank, lines, and valves are subjected to individual or combined performance tests.

In cold flow test systems, fuel and oxidizer system validations, leakage tests, pressure tests, turbo pump performance tests, and safety system tests are typically conducted. Often, water and liquid nitrogen are used instead of fuel and oxidizer to perform fuel simulation tests in these systems. Cold flow test systems help identify the performance and safety criteria of components before ignition tests, thereby preventing potential time and cost losses during development processes.

At E2T, we develop customized cold flow test systems for spacecraft based on customer requirements. Particularly in cold flow test systems where flow processes play a critical role, our E2T Data Acquisition and Control Suite simplifies your test operations, helping you save time and costs in your development processes.
