Environmental considerations are focusing attention towards using LH2 for commercial aircraft. But LH2 has unwanted properties- cryogenic and potentially explosive. Thus, aerodynamic design must be innovative, safe and certifiable.  Low energy density and heavy cryogenic tanks incur performance penalties c.f. kerosene or SAF powered aircraft.

The over-arching constraint is that the LH2 fuel system must be segregated from the passengers – no obstruction of exits and compliant with emergency landing requirements. The airframe has to reasonably survive engine disc burst.A “Gondola” concept offers an opportunity for a medium range (160-180 seat) LH2 design that will meet these challenges, featuring a twin-fuselage – one with passengers and the other with fuel tanks. This concept demonstrates clear crashworthiness, evacuation, fuel management, ground handling and other advantages.
