Energy storage to start the aircraft

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.

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 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.

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.

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.

How long does a plane last?

Specifically: Each aircraft of the fleet fulfils four missions per day, every one of 1400 km. The operating days per year are assumed to be 300, taking into account of possible downtimes for breakdowns and repairs. The estimated operating average lifespan of the aeroplane is 30 years.
