STME nozzle thermal analysis

The current summer project has the objective of carrying out a detailed thermal analysis of the Space Transportation Main Engine (STME) nozzle. The design and development of the STME nozzle has been undertaken by Pratt and Whitney in collaboration with NASA/MSFC and DoD. The nozzle design has adopted film/convective cooling techniques. The turbine exhaust has been utilized as the coolant in the nozzle cooling system.
