Technical Talk:

Challenges of More Electric Aircraft – Electric Starter Generators embedded in Gas Turbine Engines

By Dr Bicky  Bhangu

Synopsis:

The customer requirements for civil and defence aircrafts are growing and driving the need for More Electric Aircraft (MEA). This change is replacing the traditional hydraulic flight actuators with a combination of electrical and smaller hydraulic systems providing significant improvements in efficiency and reduced weight. 

The removal of bleed air system requires a separate Environmental Conditioning System (ECS) to supply cabin air rather than using the air from the engine compressor. Although the engine efficiency is improved, this is at a cost of increased electrical load. Advances in power electronics and electrical machines have permitted the use Electric Starter Generator (ESG) coupled to the gas turbine engine. 

The ESG acts as a motor to electrically start the engine, and as a generator, to convert mechanical shaft power from the gas turbine engine to electrical power, to supply the increasing on-board loads.

The market for integrated power systems for civil and defence UAVs (Unmanned Air Vehicles) is also growing. Due to space constraints a practical solution for UAVs is to employ ESGs “embedded” in gas turbine engines. An optimised electromagnetic design of the ESG is required for the provision of high starting torque and high speed operation during motoring and generation.

This presentation addresses the technical challenges faced by engineers in the integration between the electrical and mechanical systems and the challenges of embedding and coupling a permanent magnet ESG directly onto a shaft of a gas turbine engine. In addition, the presentation highlights the importance of modelling, verification and validation processes, when taking concepts from research through to design and demonstration.

Dr Bicky Bhangu is Team Leader for Electrical Systems at Rolls-Royce Singapore and is responsible for developing the capability in electrical power and control systems for Aerospace, Marine and Energy business sectors. Dr Bhangu is a Charted Engineer, has a BEng in Electrical and Electronic Engineering from the University of Nottingham, an MSc in Control Systems and a PhD in Advanced Machines and Drives from the University of Sheffield.

Dr Bhangu started his career with Ricardo Automotive, Cambridge UK, where he led and coordinated the development of electric and hybrid drive train solutions and advanced battery management solutions. In 2007, Dr Bhangu joined Rolls-Royce UK Electrical Systems group. He has since been awarded the Sir Henry Royce Award for Technical Innovation for his work on integrated power and propulsion systems and recently he was recognized as a finalist at the IET Innovation Awards – 2009. His research interests include advanced power inverter solutions and control strategies for more-electric gas turbine engines.

IET Singapore Network is in the process of applying to the PE Board for PDU points for this technical talk
