Bristol, United Kingdom

Product Owner and Aerodynamics lead for Rolls-Royce's first Agile development programme, Orpheus, a ground based demonstrator for a new centreline engine.Defined product vision for the fan and compressor sub-system. Led end-to-end delivery from preliminary design to test. Both modules were delivered at 10x the pace of a traditional development programme. Defined global preliminary design processes for multi-stage high speed fans.

Bristol, United Kingdom

Delivered an aerodynamic design for a Fan rig blade on a high speed multi-stage machine. Implemented new tools and methods for inverse design of airfoils.

Derby, United Kingdom

Fan aerodynamics preliminary design work for Civil Engines. Produced prelimary fan designs using throughflows and CFD, fan efficiency bids and sub-system trade studies that aligned with company R+T strategy for a given EIS date.Supported the design of a novel bifurcation for a large civil engine. Identified capability gaps in existing meshing and geometry creation tools. Defined requirements, implemented solutions and debugged methods in conjunction with developers. Defined, managed and supported the production of a wind-tunnel demonstrator to communicate the effect of compressor defects in a tangible manner.

Dublin

Developed robust, validated software to predict and reduce aeroacoustic airfoil noise from wind turbines in urban settings. The tool was able to predict broadband noise under various operating conditions and for multiple geometries. The code was able to use CFD results as input to the noise models, which improved modelling accuracy.Responsible for noise predictions for the EU FP7 SWIP Project, a multinational collaboration aimed at reducing barriers for wind turbine penetration in Europe. Wrote a tool to predict broadband noise for contra-rotating open rotors. Validated the predictions against existing test data, and predicted directivity. Presented this work at an AIAA conference.

Ireland

Produced lesson plans and presented interactive content to a group of learners (age 14-16) to teach them about various engineering concepts. Lessons focussed on the engineering design process, basic electronics and design projects.

Pretoria Area, South Africa

Responsible for mechanical stress analysis of an electro-optical surveillance platform, including the development of an FE model and consultation on thermal stress problems. Optimised solutions to minimise stress distributions in the primary mirror.

Improved brand awareness through training and entertainment events as well as product activations.

Pretoria

Designed and Tested a wing planform to be used on a Micro Air Vehicle for reconnaissance. Developed a MATLAB program that interfaced with a vortex lattice method to analyse a wing planform at a given operating condition. A Genetic Algorithm was implemented to numerically optimise the design based on mission criteria.Manufactured a 1:1 scale model of the final design and tested it at the CSIR Low-Speed Windtunnels. Implemented a novel method for flow visualisation by making use of thermal cameras. Results showed good validation of lift performance and separation point prediction.
