Exploration and Evaluation of Knowledge-based Engineering Approach for Liquid Hydrogen Tank Integration in existing Fuselage

Kurzfassung

This paper introduces an initial analysis conducted on an aft-type Liquid Hydrogen (LH2) tank in an aircraft, exploring different cabin definitions and tank configurations. Additionally, it delves into an investigation of the utilization of a web application to depict a Knowledge-Based Engineering (KBE) application that was developed. As aviation technology advances towards a more sustainable future, there is a growing necessity for innovative concepts to achieve zero emissions and sustainability goals. In pursuit of these goals, a preliminary study is conducted that encompasses the assessment of stability factors such as the Center Of Gravity (CG) and Static Margin (SM), along with an exploration of the range achievable when utilizing LH2 as a fuel source. For the analysis, a virtual in house cabin design tool is used, known as Fuselage Geometry Assembler (FUGA), this provides a digital model of the cabin of both single and twin-aisle configurations of commercial aircraft. The information on aircraft characteristics is provided to FUGA using the Common Parametric Aircraft Configuration Schema (CPACS). Coupling both CPACS and FUGA provides the user with a consistent model of aircraft and cabin design. For ease of use and better visualization of information from FUGA, a web-based application is developed using Flask. This enables the user to access the FUGA tool without the need to install the tool on their devices.
