Case Study

SiCTAA

SiC Technologies for Aerospace Applications

The Objective

SiCTAA will enable Rolls-Royce to develop Silicon Carbide (SiC) wide bandgap semiconductor technology for lightning strike protection and power electronics aerospace propulsion applications. The project will develop high temperature capable, radiation tolerant devices to facilitate the future More Electric Engine. The project aligns with the ATI themes of Smart, Connected and More Electric aircraft as well as Propulsion of the Future.

The Outcome

The SiCTAA project has multiple components that provide the opportunity for future benefit on production architectures. Examples of such benefits are below.

• Improved space reduction on already overly crowded Printed Circuit Boards (PCB) resulting in opportunities to reduce the overall size/weight of the Electronic Engine Controller (EEC). Targeting 50% reduction in required device installation footprint at unit level.

• Improved reliability targeted to meet the operability requirement of zero operational defects during a 25-year in-service life for all types of airline operation

• Product cost reduction making the overall controlling product more competitive (less devices required per application). The benefit of using CLDs above Tranzorb components for an EEC in a typical year based on current production rates is expected to be £540k.

• Re-shoring of production from the Philippines to Sweden and the UK.

• CSA Catapult’s involvement in the project will be packaging design and project management.
