This work will focus on establishing cost knowledge within the CAD tool within Rolls-Royce and allow very accurate cost modelling from components to whole propulsion systems.
This work allows designers to establish feasible trade-offs between manufacturing cost, emissions, performance, fuel burn etc.
The work will follow the established Value Modelling theme that has characterised a number of recent RR sponsored EngD students.
This specific EngD is aimed at developing knowledge based tools and simulations that result in tools that become established within RR and support design decision making particularly in the early design phase. This is important as early concept level decisions limit the scope of the final solution capabilities. The computational Engineering UTC has a long track record of developing software tools that are embedded within the RR decision making process (DATUM, VDD, OPTIONS, DUNDE).
These tools allow designers to study and quantify the impact of environmentally driven decisions. These are often complex trade-offs and the CEDG tools allow them to be addressed systematically, rationally and consistently. A classic trade-off early in the design process of a gas turbine will juggle TET (turbine entry temperature), fuel efficiency, direct emissions, component lives and component unit cost. A dichotomy can arise whereby attempting to reduce emissions can result in a propulsion system which is less fuel efficient which is therefore sub-optimal in terms of overall impact on the environment.
A clear goal of this research will be help construct holistic optimisation workflows to allow designers to predict such trade-offs with greater fidelity and certainty.
