With the introduction of the more electric aircraft greater emphasis is placed on the power generation and distribution architecture as a result of increased power demands and higher efficiency needs, as well as the interest in using electrical power for more flight critical applications.
Together with the steady drive for reduced weight, increased reliability and reduced maintenance, this leads to the requirement for new approaches for the aircraft electrical supply generation and distribution, managed intelligently to maximise efficiency and ensure safe aircraft operation under all conditions.
The prime aim of the project is the design, development and test of an ‘Innovative Primary & Secondary Electrical Distribution Network for Regional A/C’ based upon state of the art power semiconductors and enhanced electrical energy management (E2-EM).
The EPGDS to be designed comprising 2 Primary Power Centres - PPC, 4 Secondary Distribution Units - SDU, 2 AC/DC converters, solid-state based contactor/breakers - SSPC and externally provided System Supervisor & DC/DC converter interface between HV & LV primary bus bars.
The system will be designed to interface to the REG Iron Bird facilities.
The design of each LRU will be based upon the use of state of the art power semiconductor devices, innovative circuit topologies and embedded intelligence.
A foundation stone of the EPGDS system is the effective modelling of each of the LRU’s and the overall system to enable the investigation of diverse operating conditions, permit verification of correct functionality and highlight any deficiencies at an early stage. In addition it will permit the use of automatic code generation of each LRU embedded controller.
All designs will take into account the specification requirements for avionic equipment in order to facilitate future development to production & certification. Thermal, vibration and EMC survey of key elements will be performed.
Ceit's role in the project
The role of Ceit in the IDEN project is focused on the design, development and delivery of two bidirectional ACDC power converters which are the responsible of the high voltage bus generation in the electrical distribution network of the Iron Bird test bench. These ACDC converters will actively control the electrical energy derived from the two aircraft electrical generators to the whole distribution network and will efficiently respond to any possible load consumption variation in the aircraft simulated electrical network.
