Bavreet Ubhi: Propulsion Engineer

Engineering student driven by a passion for turning complex ideas into functional, high-performance aerospace systems. I specialise in propulsion and composite structures, with experience that spans the entire engineering lifecycle—from early-stage concept modelling and materials research to fabrication, integration, and full-scale testing. My work focuses on delivering designs that balance performance, reliability, and manufacturability, particularly within the demanding context of high-pressure hybrid rocket engines.

Design and Development Tools

Proficient in Fusion 360, Creo Parametric, and Ansys. Skilled in Python and MATLAB for analysis and simulation.

Manufacturing & Testing

Hands-on experience with manual/CNC machining, composite layups, and hybrid engines. Confident in fast-paced, safety-critical environments.

Composite Overwrapped Combustion Chamber

The Solaris MkIII combustion chamber was engineered as a Type V Composite Overwrapped Pressure Vessel (COPV), featuring a liner-less all-composite structure optimised for high stiffness-to-weight performance. Designed to safely operate at 60 bar chamber pressure, it incorporated a carbon-fibre overwrap architecture tailored to withstand both the internal pressurisation loads and the intense thermal gradients produced during hybrid combustion.
Following manufacturing and qualification, the chamber underwent a full-scale static fire test at the Airborne Test Facility in the United Kingdom, where its structural integrity, thermal behaviour, and pressure performance were validated under representative operating conditions.

Over 500 hours of design, simulation, and hands-on manufacturing work went into developing the composite chamber. This included iterative layup optimisation, material testing, and precision fabrication of the carbon-fibre overwrap. The image shown depicts the chamber fully assembled and prepared for testing, following final inspection and integration of all structural interfaces.
