Undergrad Effects of the centre of gravity on aircraft's stability
I'm working on a feasibility study for the integration of a liquid hydrogen storage tank for a Boeing 737-800. The tank weighs approximately 5000 kg and must be located towards the rear of the aircraft. I understand that this will shift the centre of gravity slightly further back and... -

Undergrad Modelling Liquid Hydrogen Boil-Off Rate
Certainly. Shape = horizontal cylinder with hemispherical end caps, volume = 30.02 m^3, initial liquid volume = 29.44 m^3, inner diameter = 2.93 m, length = 2.5 m (cylinder), relief pressure = 0.25 MPa, liquid temp = 20 K, pressure = 0.092 MPa, ambient temp = 293.15 K, insulation (MLI) thermal...- JB312

Undergrad Modelling Liquid Hydrogen Boil-Off Rate
The relevant thermal conductivity, heat transfer coefficients, and thicknesses along with all other required parameters are known. I have attempted to use the online simulation tool boilFAST to simulate each scenario however, the results show a negative spike in boil-off rate which I don't see...- JB312
