6 FAQs about [Aircraft energy storage requirements]
How can energy storage support HEP for larger aircraft?
Energy storage is one of the fundamental technologies to support HEP for larger aircraft. The main energy storage technologies for aircraft are the batteries, but FCs and supercapacitors are also being tested. Harvesting systems such as solar photovoltaic cells can be added to any of the cited storage technologies.
How to determine the size of aircraft energy storage systems?
Based on the comprehensive analysis of hydrogen economy, FC aging cost, and aircraft stability, a multi-objective parameter optimization model is established to decide the size of aircraft energy storage systems and hyper-parameters in the power controller.
Can fuel cell and battery energy storage improve aircraft performance?
Recent developments in fuel cell (FC) and battery energy storage technologies bring a promising perspective for improving the economy and endurance of electric aircraft. However, aircraft power system configuration and power distribution strategies should be reasonably designed to enable this benefit.
How to improve the efficiency of aircraft energy storage system?
To improve efficiency, the rated power of FC should be enlarged, which could bring serious weight penalty problems for the aircraft. After the battery is deployed in the aircraft energy storage system, the working points of the FC stack can be generally moved to the high-efficiency zone.
Why do aircraft use electrical energy storage systems?
In today’s aircraft, electrical energy storage systems, which are used only in certain situations, have become the main source of energy in aircraft where the propulsion system is also converted into electrical energy (Emadi & Ehsani, 2000).
Why do aircraft need solar energy storage?
In solar-powered aircraft, an energy storage system is needed to meet the intense power demand during takeoff, landing, and some maneuvers and to provide energy to continue uninterrupted flight at night or in conditions of insufficient solar radiation (Gang & Kwon, 2018).
