Onboard power systems
Over the last decade, onboard power systems have advanced significantly due to the increased adoption of More Electrical Aircraft (MEA), All Electric Ships (AES), and electric high-speed rail. By replacing certain mechanical, hydraulic, and pneumatic functions with electric systems, engineers can now reduce costs, increase architectural flexibility, and improve acoustics. While onboard power systems offer significant benefits, stringent regulations concerning reliability and survivability require more comprehensive control and protection testing. As a result, airplane, ship, train manufacturers, and suppliers must spend more time designing, testing, validating, and certifying this new generation of complex electrical systems.

Research and Innovation
More electric aircraft pushes HIL to new heights
The increased usage of electrical power intensifies the power demands on the electrical system, placing new constraints on dynamic performances and power quality. Today’s new power systems architectures must be designed, extensively analyzed, tested, validated, and certified prior to implementation in actual aircraft.
Real-time simulation of MEA has been used to ensure compliance with a wide variety of avionics test standards. Read more about using real-time simulation on the Bombardier Global Express for avionics standard validation.
