SGO - Management of Aircraft Energy

The Management of Aircraft Energy encompasses all aspects of on-board energy provision, storage, distribution and consumption. MAE aims at two major objectives. The first one is to develop and demonstrate All-Electric Aircraft System Architectures (power by wire), involving energy users to facilitate the implementation of advanced energy management functions and architectures. This also entails the suppression of hydraulic fluids and related negative environmental impacts. The second objectives is to adapt and demonstrate the control of heat exchanges (partly necessary due to the all-electric concept) and reduction in heat waste within the whole aircraft through advanced Thermal Management.

In order to support those objectives, the following enabling technologies will be developed:

    • Electrical power generation, distribution and conversion technologies
    • Electrical energy management architecture
    • Systems using electrical power (ice protection, environmental control systems, etc.)
    • Overall thermal management solutions of aircraft/engine systems
    • Optimisation of electrical drive system cooling, and interaction with the all-electric aircraft equipment systems technologies
    • Energy recovery/energy exchange systems, to reduce heat wastage.

 

These technologies will lead either to a reduction of systems related weight or aircraft related weight, which will in turn reduce the fuel consumption. The extent of the weight reduction is to be assessed by both system suppliers and aircraft manufacturers on vehicle level, as previous studies have shown this to be a complex technical challenge. Another major benefit is the reduction of the systems related power extraction from the engine (non-propulsive thrust). Previous projects have shown that gains up to 40% are achievable, and will enable the engine to be further optimized as well. MAE will benefit from the results of these previous studies (MOET, POA) and further mature the technologies up to TRL 5/6, with target dates for the final demonstrations ranging from late 2012 to 2015 depending on the technologies.

These challenges will be met by:

  • The development and demonstration of All-Electric Aircraft System Architectures (power by wire), using as input definition by airframers, involving all energy users to facilitate the implementation of advanced energy management functions and architectures. This also entails the suppression of hydraulic fluids and related negative environmental impacts.
  • Achievement of adapted and demonstrated control of heat exchanges (partly necessary due to the all-electric concept) and reduction in heat waste within the whole aircraft through advanced Thermal Management.
