Aircraft with electric machine for turboshaft engine assistance
A recently granted patent (Publication Number: US12012215B2) discloses an innovative aircraft design featuring a device connected to a turboshaft engine, with the ability to switch between seven different operating modes. These modes include standard start-up, fast start-up, power assistance levels, mechanical resistance application, ventilation support, and rest mode for the electric machine. The device is equipped with a controller to manage these modes, ensuring optimal performance and efficiency during flight. In the event of a failure of the second turboshaft engine, the controller is programmed to implement specific modes sequentially to maintain flight stability and safety.
Furthermore, the patent details a method for controlling the aircraft, emphasizing the importance of the electrical power source capacity to support the different operating modes. The method involves implementing the various modes based on specific time periods, ensuring smooth transitions between modes during flight. With a focus on enhancing engine performance, safety, and reliability, this patented technology showcases advanced capabilities in aircraft design and operation. The detailed description of the operating modes and their functionalities highlights the sophistication and versatility of the aircraft system, setting a new standard in the aviation industry for efficient and resilient aircraft performance.
