Airbus Helicopters has come up with a life-saving patent proposing an emergency battery framework for single-engine rotorcraft. Intended to keep up rotor power in case of a motor fail, the framework will help pilots in performing safe autorotation arrivals, as per a European Patent Office patent distributed in June.
Extensively containing a battery pack and electric engine associated with the gearbox, it likewise incorporates sensors to empower a quick identification of a drop in rotor speed characteristic of a motor failure and afterward actuation of the back-up framework. Noticing the overwhelming outstanding task at hand looked in the critical minutes following motor failure, the documenting says that without snappy activity the rotor speed will down and the helicopter will crash.
It says that notwithstanding wellbeing benefits, the back-up framework would ease certain operational confinements forced on single-engine helicopters, especially a European restriction on the overflight of bigger developed zones. Likewise, most extreme drop weight could be expanded, given the extra security edge gave, according to the patent application.
The framework would empower the identification of motor failure before it is past the point of no return, says the patent, in a split second furnishing back-up capacity to help with the autorotation and, at the purpose of arriving, to help the speed decrease required to stay away from an exceptionally substantial contact with the ground.
Sensors to empower quick identification of a motor fail could screen various boundaries, including rotor or motor RPM, close by temperature or weight. Be that as it may, the application takes note of that the location framework must be sufficiently complex to recognize a real motor failure and phases of the flight where rotor speed may normally fall at any rate, “restricting the danger of distinguishing a non-existent failure”.
Moreover, the helicopter pilot ought to have the option to either incapacitate the framework – to play out certain preparation missions. The patent calls attention to that the size of the framework is constrained by a necessity not to add critical load to the craft. Airbus Helicopters’ head of advancement Tomasz Krysinski as of late showed that the framework it proposing to also test an electric motor for their future crafts.
