As the aviation industry continues to seek sustainable solutions to reduce its carbon footprint, a recent patent filed by MTU Aero Engines AG proposes an innovative hydrogen-based fuel system for aircraft.
This system aims to enhance the efficiency and safety of hydrogen fuel storage and supply for aerospace applications.
At the core of the invention is a sophisticated fuel system designed specifically for hydrogen storage and supply in aircraft. The system features a dual inner tank configuration – a first inner tank and a separate second inner tank, each designated for storing hydrogen. These inner tanks are enclosed within an outer tank, providing an additional layer of protection and insulation for the volatile hydrogen gas.
The separation of the inner tanks is a key aspect of the design. Each tank is fluidically connected, yet independently operated, to one or more supply devices that channel hydrogen to the aircraft. This means that the failure or depletion of one tank does not directly affect the other, enabling redundancy and therefore improving the safety and reliability of the fuel system.
The modular structure of the hydrogen fuel system is poised to bring several advantages to aircraft design and performance. By having separate inner tanks, the weight distribution within the aircraft can be more effectively managed, potentially leading to improved flight stability and fuel efficiency. Additionally, isolating the fuel systems helps mitigate risks associated with hydrogen handling, given its highly flammable nature.
Beyond the fuel storage and supply mechanism, the patent also elaborates on its integration within aircraft. The compatibility of the fuel system with existing aircraft designs or new builds positions it as a versatile solution for aircraft manufacturers aiming to transition to hydrogen-powered engines.
With the filing of this patent, MTU Aero Engines AG is contributing a significant piece to the puzzle of adopting hydrogen as a viable and sustainable aviation fuel.
