6 FAQs about [Aircraft combat energy storage device]

How does a hybrid energy storage system work?

In this paper, a dynamic model of a hybrid energy storage system composed by a LiFePO 4 battery and a supercapacitor, coupled to eight regenerative electro-mechanical actuators (r-EMAs) employed for the flight control surface, is implemented to store recovered energy and to drive r-EMAs.

Can a battery-supercapacitor based hybrid energy storage system smooth pulse power?

Cheng et al. introduce a configuration method of a battery-supercapacitor based hybrid energy storage system to smooth the pulse power and feedback energy in electrical power system of MEA.

What is a more electric aircraft?

In such framework, the concept of a More Electric Aircraft has been developing in order to introduce electrical systems for energy recovery and storage on-board.

How can a LiFePo 4 battery save energy?

Such strategy allows, with respect to the case of a not hybrid storage section constituted by a LiFePO 4 battery, to reduce the storage section weight, extend battery lifetime since dangerous power spikes are accomplished by the supercapacitor, as well as recover energy thanks to the installation of the r-EMAs.

How regenerative actuators affect energy storage?

The energy analysis resulting from the introduction of regenerative actuators coupled to a hybrid energy storage system takes into account two different contributions: the weight reduction, which leads to a decrease in fuel used by the aircraft; the recovery of the amount of energy regenerated by the actuators.

Why are electrical systems used in on-board applications?

As a matter of fact, electrical systems are being used in several on-board applications, which have traditionally been powered by hydraulic or pneumatic sources . Such systems offer far more options for reconfigurability as well as for advanced prognostics and diagnostics .
