Abstract
The More Electric Aircraft (MEA) concept has started to define the future of aircraft electrification. The electrical system will certainly play a crucial role in redefining energy utilization on-board. With the increasing demand of electrical energy, MEA power system architecture is a key enabler for the integration of future technologies. Nevertheless, newer designs must comply with the strictest safety and reliability specifications for successful adoption. This paper presents the design of a MEA DC power distribution system considering a set of reliability specifications. The novelty relies in the adoption of a network design-based model for MEA power system construction that allows explicit design formulations as Mixed Integer Linear Programming MILP problems. This approach will provide an effective way to comply with reliability specifications by introducing the concept of failure-resistance or survivability.
Highlights
The aircraft distribution system is a network that allows electric power flow from the engine-driven generators and back-up systems to the loads
The novelty of this paper consists in the adoption of a network design-based model for More Electric Aircraft (MEA) power system topology optimisation and an effective way to comply with the reliability specification, introducing the concept of failure-resistance or survivability
Contract-based Design (CbD) optimizes the topology through a two-step iterative algorithm where the number of reliability constraints increases on every iteration
Summary
The aircraft distribution system is a network that allows electric power flow from the engine-driven generators and back-up systems to the loads. These loads comprise all of the control systems to provide a convenient and safe flight from the source to the destination. This paper will address the investigation on reliable design of electrical DC distribution system alternatives for the future MEA in the context of costeffectiveness. The novelty of this paper consists in the adoption of a network design-based model for MEA power system topology optimisation and an effective way to comply with the reliability specification, introducing the concept of failure-resistance or survivability
