Abstract

Today’s engineers are facing new challenges when it comes to implementing more-electrical architectures, specifically within the aviation industry. Therefore, tools such as Pacelab Suite can be used to conduct preliminary analysis of such modern architectures within an aircraft for a specific designed mission. This work mostly pertains to the development and analysis between a conventional and a more-electric architecture of a regional aircraft on Pacelab. Conventionally, three types of non-propulsive power are used to drive the various sub-systems in an aircraft: hydraulic, pneumatic and electrical sub-systems. Recently, a trend towards more-electrical architecture is being adopted in the aviation industry owing to the many drawbacks identified with conventional sub-system architecture. The conventional architecture of a large regional aircraft (ATR-72) was studied and the complete architecture of the electrical, hydraulic, flight controls, fuel and pneumatic systems is modelled using the Pacelab Suite. The conventional model of the aircraft is subjected to different scenarios in order to evaluate the aerodynamics, fuel consumption and electrical energy performance for a comparison with more electrical versions. The intent of this work is to analyze whether one of the two architectures significantly outperforms the other considering a mission-level metric. Further, it is also planned to subject the more-electric model to the same scenarios as the conventional model and draw conclusions on the merits and demerits of introducing More-Electric Aircraft (MEA) architecture in a regional aircraft.
