THE NEED
To accurately analyze the system performance of an aircraft electrical system
THE SOLUTION
Maxwell®, Simplorer®, PExprt™, RMxprt™, Optimetrics™
The design and simulation of aircraft electrical systems is often compromised by the sheer complexity of the inherent subsystems: power generators, rectifiers, converters, and electromechanical loads.
In the past, engineers attempting to accurately simulate the electrical system have been stymied by the need for expertise and understanding of all the subsystems and their interactions. Overwhelmed by the complexity of the task, many engineers revert to an expensive build-and-test methodology rather than fully employ the power of simulation.
Crane employs a more scalable method using dedicated tools to generate detailed nonlinear models for each subsystem and an approach to easily link them together to view system performance. Optimization algorithms are used to design the synchronous generator model, and the Transformer Rectifier Unit (TRU) is parameterized so the magnetic components can undergo "what-if" analyses.
