## ABOUT THE ROLE
As a CFD & Propulsion Intern, you will assist in the design, analysis, simulation, and testing of aerodynamic and propulsion systems for AnduraX's reusable re-entry vehicle and future propulsion technologies. You will work on Computational Fluid Dynamics (CFD), propulsion system design, internal and external flow analysis, thermal-fluid systems, and experimental validation. This role combines simulation with hands-on engineering, providing exposure to propulsion hardware development, engine testing, and multidisciplinary vehicle design.
## RESPONSIBILITY
* Perform CFD simulations for external aerodynamics and internal flow applications using industry-standard software.
* Assist in the aerodynamic analysis of lifting bodies, control surfaces, and re-entry vehicle configurations.
* Support propulsion flow simulations involving injectors, combustion chambers, nozzles, and feed systems.
* Assist in mesh generation, boundary condition setup, solver configuration, and result post-processing.
* Perform engineering calculations for fluid flow, heat transfer, compressible flow, and propulsion performance.
* Support the design and sizing of propulsion components such as injectors, nozzles, valves, tanks, and feed systems.
* Participate in propulsion testing, cold-flow testing, and experimental validation activities.
* Analyse simulation and test data to validate models and recommend design improvements.
* Assist in preparing engineering reports, technical documentation, and design presentations.
* Collaborate with Aerodynamics, Structures, Mechanical Systems, Avionics, GNC, and Systems Engineering teams throughout the product development cycle.
* Participate in prototype development, subsystem integration, and flight campaign preparations.
## REQUIREMENTS
