This is particularly true when the electrification of the Environmental Control System (ECS) and Ice Protection System (IPS) are considered. Firstly, electrified OBS should reduce fuel consumption because of their greater efficiency. The trend towards on-board systems (OBS) electrification provides different benefits. This trend started some years ago, defining the More Electric Aircraft (MEA) and All Electric Aircraft (AEA) concepts, where the electrification of the aircraft subsystems is pursued. In this context, one of the most promising solutions is aircraft electrification. With the aim of further improving the present aeronautical products, innovative solutions have to be applied. This led to a continuous aircraft refinement and optimization in different disciplinary areas. In the last decades, aviation has been called to increase the safety, efficiency, and remunerability of its products. A possible mass saving of 2.6% of aircraft MTOM can be reached by properly selecting the systems technologies used. Finally, using the workflow which allows for greater integration, interesting differences can be noted when comparing systems with different levels of electrification. The results show an error of 40% in on-board systems assessment when the discipline is not fully integrated. Starting from a non-iterative systems design, other disciplines such as aircraft performance, engine design, and aircraft synthesis are gradually added, increasing the sensibility of the aircraft design to the different systems architectures. The study is carried out from a systems design perspective, analyzing the effect of electrification on aircraft design, with different MDA workflow arrangements. This paper deals with a progressive integration of the discipline to examine the partial or total effect of the systems design inside an MDA workflow. In this way, the systems design discipline should be integrated from the first design iterations. However, seeing the trend towards systems electrification, multiple architectures can be defined and each one should be evaluated during the first tradeoff studies. It might be understandable when a single on-board system architecture is considered, especially when a conventional architecture is selected. The on-board design discipline is sometimes ignored during the first aircraft design iterations. ![]()
