LN2 Pressurization and Control System

Introduction

LN2 chilling and pressurization system is a fully automated CRYO temperature simulated test facility using liquid nitrogen for structural load testing of various components used in space launch vehicles.

Applications and features

The aggregates under test are to be pre-chilled to cryo temperature of 80 K to 110 K initially and a required chamber pressure is to be maintained with close accuracy of ±0.2 bar during the test. After the stabilisation of pressure in cryo temperature, the structural loads will be applied using hydraulic/pneumatic actuators. The maximum duration of the test is of the order of one hour to three hours. During this period the pressure and temperature is to be controlled within the specified limits automatically.
