System for the control of various gases for a rocket launch pad: Case Study

This project dictated a compact design providing high flow dynamics and close and accurate control of the three main gases used for launching of a multi-stage rocket. The individual rocket launch pad gases lines for nitrogen, helium and air, (which are needed for blanketing, propulsion, and command functions respectively) are each supplied from a 400 Bar (6000 PSI) source through a series of distribution units to the main regulation and control stations of the launch pad.

The control of each supply line - thirty (30) in total - is afforded by stop valves, electro-pneumatic stop valves, regulators and check valves. To meet with the overall space envelope of the rocket launch pad installation, the cartridge valve system was chosen over conventional valves.
