Mechanical systems are being enhanced across the company’s main business sectors and, sometimes, replaced with more electrical systems, which are more flexible in terms of installation, operation, maintenance and management. Examples of these changes are:
The technologies described above may seem very different, but the basic technologies for the Electrical System used in these applications are very similar, with a number of key characteristics.
Despite the different applications of the systems there are common themes across all the sectors:
Many new ships are moving to an electrical power system where all the engine power is converted to electricity and provides all the needs via a central power system:
The main drivers for this are:
Many new cruise ships and large naval ships are Full Electric and this is increasing in other areas such as Merchant.
The civil aerospace industry is also moving towards more electric architectures. Studies have been performed to try and quantify the benefits of replacing traditional mechanical systems with electrical systems.
Today we have the Boeing 787, which which will be the world's most electric aircraft when it enters service.
The engine of an aircraft is the source of electrical power for all the systems on the aircraft, hence more complex electrical systems have a significant impact on our engine design.
We must therefore understand the systems better to optimise the design of our gas turbines.
We must be able to:
Future aircraft may increase these trends.
Power requirements are driving novel design. Unmanned aircraft (UAV) are already flying and are seen to be key to the future in the Defence Aerospace sector. UAV’s can fly for many days, non-stop. Electrical systems can be managed to minimise fuel consumption, more than mechanical systems.
