In this article, a numerical study is presented on a lightweight electric aircraft, whose battery-based architecture is converted to a fuel cell-based architecture with the contribution of a battery pack that essentially intervenes in the take-off phase and, in addition, of a pack of ultracapacitors to prevent high discharge rate of the battery. Systems based on hydrogen fuel cells exhibit better performance in terms of range and endurance. As is known, electric propulsion can be based on different electrochemical sources nowadays, the widely used systems are developed on lithium battery packs, especially in automotive, where requirements in terms of gravimetric and volumetric energy densities are not so stringent compared to the aeronautical sector.
#ANSYS 11 AND ANSYS SIMPLORER 11 FULL#
More Electric Aircrafts are progressively giving way to full electric aircraft that are expected to represent the next revolution in aviation. The aviation sector is firmly committed to reducing harmful emissions and electric propulsion promises to tackle both pollution and noise at the same time.
Such a developed prototype allows both accurate and simple characterization and optimization to be made possible. The simulation results show the good feasibility of the motor model and control method, which achieves the desired effect and fast response with a small torque ripple as well. The PMSM drive system under different input reference speeds was analyzed by simulation, which testified that co-simulation of the magnetic and electrical domain is necessary to capture all applicable effects.
#ANSYS 11 AND ANSYS SIMPLORER 11 SOFTWARE#
A co-simulation method based on Ansys software (Maxwell and Twin Builder) and MATLAB/Simulink for Permanent Magnet Synchronous Motor (PMSM) model is presented, which can improve the design of the PMSM and evaluate its performance by Rotating Machine Expert (RMxprt) when any slight modification of parameters and output inaccuracy occur. To achieve these requirements, a real-time control-oriented electric motor model is essential. Powerful waveform analysis tools give engineers the ability to analyze responses, extract measurements, and perform detailed studies of power system behavior.Electric vehicles (EVs) should have an electrical motor with high efficiency, high power density, and a wider constant power operating region, as well as ease of control and inexpensive manufacturing cost. Its proven solver technology is designed to handle the highly nonlinear nature of power circuits efficiently and accurately, including switching elements, analog and digital control, and a mixture of system time constants and multi-domain effects. Simplorer libraries include a broad range of state-averaged and switch level components that support modeling at different levels of fidelity required through stages of development.
Simplorer has a long history of success in simulating and analyzing complex power electronic systems.
With a unique ability to integrate power electronics, multi-domain dynamics and embedded software, Simplorer is used for electric drives and electromechanical system design, power generation, conversion, storage and distribution systems, EMI/EMC studies, and general multi-domain system optimization and verification. It models and simulates multi-domain systems in the automotive, aerospace, electronics, energy and industrial machinery segments. Ansys Simplorer is a key part of model-based design flows in organizations around the globe.
