compute_cabin_weight(vehicle, settings)[source]#

Weight estimate for the cabin (forward section of centerbody) of a BWB. Regression from FEA by K. Bradley (George Washington University).

Assumptions:

-The centerbody uses a pressurized sandwich composite structure -Ultimate cabin pressure differential of 18.6psi -Critical flight condition: +2.5g maneuver at maximum TOGW

Inputs:

cabin_area - the planform area representing the passenger cabin [meters**2] TOGW - Takeoff gross weight of the aircraft [kilograms]

Outputs:

W_cabin - the estimated structural weight of the BWB cabin [kilograms]
