More Electric Aircraft (MEA) is a promising aircraft, replacing air pressure system, hydraulic systems and mechanical systems by power system. Nevertheless, the increase of electrical equipment inevitably leads to more problems in aircraft safety problems, of which the arc fault has a great influence. This manuscript is aimed at series arc in because it's not easy to detect. To solve the problem of...
For saving energy and improving the performance of the airborne systems, modern aircraft increasingly uses electrical energy to replace the current hydraulic, pneumatic energy on the aircraft. The goal of more electric aircraft is to obtain high performance and high efficiency with electric drive equipments to replace mechanical, hydraulic and pneumatic equipments directly driven by the original engine...
This paper presents a modeling study of an electrical power source for more electric aircrafts. It was designed with a PI (proportional-integrator) automated control for dq currents of the electrical machine, using the non-linear model of it. Using the dimensionless linear model, it was designed an optimal control structure based on a quadratic quality criterion (LQR) to validate the theoretical results...
A today's trend within the aircraft industry is towards a so-called More Electric Aircraft (MEA) architecture, using electric power as single type of energy to supply most of the systems on board of an air vehicle. Besides the various advantages, e.g. improved efficiency, reduced operating costs, etc., this will increase the complexity of the electrical system and therefore have an impact on the related...
Future electrical loads and increasing load trends will eventually exceed generating capacities of existing Electrical Power Systems (EPS) designs in fast jet aircraft. Space constraints, weight constraints and aerodynamic implications means simply up scaling generator size is impractical. The future addition of avionics, pilot interfaces, sensor system upgrades such as radar and the shift to the...
