This paper presents the design methodology for integrating a hydrogen solid oxide fuel cell/gas turbine (SOFC/GT) propulsion system into blended-wing–body (BWB) aircraft and tube-and-wing (T&W) configurations 365 162 passengers. The utilizes sizing modeling tools that encompass aerodynamic properties, structural design, powertrain integration. proposed BWB T&W are compared against conventional models like B777-300ER B737-800. Key results indicate significant reductions in consumption emissions. For instance, aircraft, on average, exhibits 56% reduction Megajoule of energy per passenger-kilometer to aircraft. analysis highlights environmental benefits, with [Formula: see text] equivalent emissions being significantly lower hydrogen-powered models. total takeoff weight passenger BWB-365 is 714 kg, 916 kg B777-300ER. Hydrogen configurations, also show 21% increase 99.48% decrease Moreover, exhibit reduced despite higher weights. study underscores potential SOFC/GT systems enhance efficiency reduce impacts future

Liquid hydrogen has the potential to significantly reduce in-flight carbon emissions in aviation industry. Among most promising aircraft configurations for future hydrogen-powered are blended wing body and pure flying configurations. However, their tapered flattened airframe designs pose a challenge accommodating liquid storage tanks. This paper presents design guide conformable pressure tanks storage. The proposed tank feature multi-bubble layout subject low internal differential pressure. objective is provide designers with simple geometric rules practical guidelines simplify process of Various discussed, starting two-bubble advancing more complex multi-segment layout. A comprehensive methodology established, providing step-by-step procedure highlighting each step process.
