Awaiting Public Summary

We propose to extend the capabilities for DSM of large multi-functional electrical generators intended for future civil More Electric Aircraft. Existing models are inadequate for evaluating the conflicting requirements for generators with engine electric start capability. This includes the thermal effects of power electronic drives and heat rejection from the generator local to the engine. Integrated electromagnetic, thermal, and mechanical models are needed. The team consists of a major electrical generator supplier (Goodrich), a major airframe manufacturer (Airbus), and academic experts in electrical machine control (UoBristol). The approach will be to integrate existing data and analysis techniques with power electronic component descriptions to create a multi-physics generic model for high power electrical machines. We will demonstrate the model by simulating a 300KVA electric starter-generator and examining system-level trade-offs.

Awaiting Public Summary

We propose to develop and exploit virtual reliability models to simulate operation wear out and failure mechanisms in electronic power modules. These devices underpin a broad range of applications in automotive, aerospace, traction and power distribution systems. Environmental legislation is forcing the development of new systems to reduce noise and harmful emissions. This requires development of next generation power modules. Testing and qualification of these devices is expensive and time-consuming. New integrated virtual reliability models are needed to identify potential problems early in the design stage to improve reliability, reduce time to market and drive down overall device cost, thereby improving the UK''s industrial competitiveness. The consortium brings together a diverse industrial base to lever expertise in modelling, design, testing and manufacturing which is required to enable the development of this complex design tool.
