Abstract:
High altitude test facilities are established, for testing upper stage rocket engines. Typical HAT facility consists of Vacuum system, diffuser system, cooling system and ejector system. Normally air/GN2 is used as active gas for ejector system which is stored in high pressure cylinders. Wind tunnel facilities are used for conducting aerodynamic simulation experiments in various flow velocities. Similarly wind tunnel facility requires the systems like diffuser system, test section, nozzle to generate required upstream flow velocity and associated gas storages. In this article, the feasibility study of conducting wind tunnel experiments by utilizing the existing infrastructure in HAT facility by suitably modifying the facility. For this detailed theoretical study, CFD analysis is carried out to propose this conversion without affecting the existing functional requirements of the facility.
