The Next Generation Aircraft

OPAL-RT offers a range of solutions in real time digital simulation to aerospace manufacturers and suppliers seeking to improve their aircrafts’ performance, reliability, fuel efficiency and to reduce operating and maintenance costs. More Electric Aircraft (MEA) and, ultimately, all-electric aircraft are now emerging and leading the way within the aerospace industry, and OPAL-RT is helping them by increasing the reliability with real time simulation tests.

Ensuring the Safety and Reliability of Aircraft Power Systems

Real-time digital simulation is increasingly critical as the incorporation of new technologies in today’s aircraft spreads, including advanced power electronics systems, intelligent control systems and state-of-the-art energy storage technologies. Real-Time digital simulators also provide accurate results at the design stage, enabling more efficient planning for potential issues with equipment failure or plane damage, and ensure a continuous power supply for electric loads.

Real-Time Simulation of a Boeing 787

The Real-Time Simulation demonstration of a Boeing 787’s More Electric Aircraft (MEA) Electrical Power Generation and Distribution System (EPGDS) consists of a comprehensive CPU-FPGA co-simulation of the B787’s AC and DC electrical buses including variable frequency starter generators (VFSG), inverters, ATRUs, electric machines, loads, as well as APUs. Backup buses are also simulated. Such state-of-the-art real-time simulations can be used for Hardware-in-the-Loop (HIL) tests of control, protection and data logging devices during the R&D, certification or even production stages of an MEA’s lifecycle.

More Electric Aircraft (MEA) OPAL-RT Toolset Demonstration

The aerospace industry is foreseeing a lot of challenges to improve performance, efficiency and maintenance costs of manned aircraft. Due to the difficulty to improve a long proven classic airplane design, the industries transition to More Electric Aircraft (MEA) is inevitable. By the electrification of the aircraft, the industry will push the concept of hybrid electric powered aircraft and ultimately reach an all-electric aircraft level. As a result of our extensive experience in power electronic simulations, OPAL-RT has the right tools to push forward the testing and validations of the ever-growing electrification of airplanes.

The heart of our solutions is eHS, a generic, reprogrammable FPGA-based electrical hardware solver. eHS enables users to bring any model created into real time using the simulation tools of their choice: SimScape Power System, PSIM™, PLECS Blockset™ or Multisim™.

This way, we expand our capabilities by allowing multiple solvers to work together on multiple FPGAs as a single simulation. This allows us to present a Real-Time Simulation demonstration of a Boeing 787’s More Electric Aircraft (MEA) Electrical Power Generation and Distribution System (EPGDS).

The Next Generation of Testing Tools

OPAL-RT provides the widest range of proven, state-of-the-art real-time simulation solutions for engineers working on More Electric Aircraft applications. Accelerate projects by testing designs with Hardware-in-the-Loop (HIL), while reducing overall project cost and staff and equipment risks. Benefit from the same advanced OPAL-RT solvers and libraries already being used across the industry to precisely simulate complex More Electric Aircraft applications.

More Electric Aircraft Testing tool ARTEMiS-SSN


ARTEMiS-SSN provides the industry’s fastest and most accurate solvers for microgrid and More Electric Aircraft applications. With ever-shorter configuration of transmission lines and thinly coupled grids, standard HIL solving methods can be prevented from work optimally.

ARTEMiS solvers and algorithms use advanced decoupling techniques to circumvent this limitation, while providing accurate real-time simulation results.

At the heart of OPAL-RT real-time simulation is eHS, a generic, reprogrammable FPGA-based electrical hardware solver. eHS enables users to bring into real-time any model created in the simulation tools of their choice: SimScape Power System, PSIM™, PLECS Blockset™ or Multisim™.

More Electrical Aircraft (MEA) Pushes HIL to New Heights

Virtual MEA systems simulation offers a cost effective and time efficient approach. In this context, BOMBARDIER and OPAL-RT are participating with collaborators in the aerospace industry on the development of a Multi Electrical System Integrated Simulator (MESIS) that integrates MEA systems models into a real-time co-simulation platform. This paper provides a high level overview of the MESIS scope and objectives. The practical implementation of MESIS involves key technological aspects and challenges that will be addressed by simulation strategies presented in the paper.
