Some major market stakes for aircraft Manufacturers are the following:

  • The cost and efficiency of the aircraft as well as its design and manufacturing must be the most competitive.
  • Safety and environmental gains continue to be improved In the meantime. There is a strong demand for every industry to reduce emissions and burn less fuel.
  • With the increasing requirements for data gathering by manned and unmanned aircraft, system designers now have to install data processing networks with more capacity and higher speeds aboard aircraft.
  • Bandwidth and performance requirements will continue to increase so that the ability to scale is a key requirement.

An aerospace network has more demanding needs than a commercial/industrial network because Safety in aerospace is primary:

  • High levels of redundancy, security, and environmental resiliency and error/failure identification are critical.
  • Proven performances and the use of certified standards are critical for acceptance.
  • The network should be capable of supporting precise real-time application requirements such as fly-by-wire.

A More electric aircraft (MEA) is one other major industry trend. The MEA design philosophy is based on the use of electricity to partially or totally replace traditional heavy power systems to thus reduce the complexity of integration and general maintenance. This concept was conceived during World War II to reduce the enormous weight of aircrafts. Fly-By-Wire was one of the first MEA concepts to be implemented, allowing mechanical pulley-based flight control systems to be replaced by an electric signal transmission system while maintaining hydraulic actuators.

The benefits of the MEA are generally identified as:

• Simplification towards a single power source
• Simplicity, less maintenance costs and lower fluid leak risk
• Mechanical failure risk and fire/explosion risks are reduced
• Reuse of purge air from engines
• Less weight, greater fuel savings
• Greater design versatility
• Better use of space.

The trend of a more electric aircraft is very promising for EtherFly that can be applied to a large variety of use cases:

• Power Modular Control command
• Electrical Power distribution
• Braking systems control
• Landing systems
• UAV’s (Unmanned Aerial Vehicles) or Drones

And more generally, any avionic system with distributed motors drives

A EtherFly empowered architecture will provide the Customer with:

• Smarter and more flexible systems
• Optimized and scalable systems
• More modular and reusable systems
• More economic systems

Additional use case of EtherFly is the backbone bus for control and integration of sub systems, devices and applications. The related business stakes are also high by reducing the number of cables without any concession for safety:
• Reduce Wiring Harness and cabling costs
• Reduce weight and save fuel consumption
• Make the maintenance of planes easier
