The electricity an aircraft requires during a flight is normally generated via
the engines. To ensure that there will always be a sufficient current supply
to the flight controls and essential onboard functions even if the engines
fail completely, modern aircraft have a ram air turbine (RAT) – a deployable
turbine that generates current via the airstream. RATs have a disadvantage,
however: Their output depends on the flight situation. Liebherr-Aerospace
Lindenberg GmbH is using dSPACE hardware and software to develop an
alternative, fuel-cell-based emergency power system that supplies
electricity
no matter what the situation is.
