QUESTION 1. A hydrazine tank that is designed by the Orbital Propulsion Center, is made of T16AI4V STA (3.7164.7), i.e. a titanium alloy, is shown in the figure. (a) If the volume of the tank is 150 It, calculate its radius. (b) If the gauge pressure is more than 36.9 Bar, the material undergoes plastic deformation and if the gauge pressure is more than 49.2 Bar, the material fractures. Thus, calculate the tank thickness, t, such that the tank operates safely. (c) Under operational conditions (MEOP), calculate the absolute maximum shear stress. http://www.space- propulsion.com/spacecraft- propulsion/hydrazine- tanks/index.html 104 to 177 Litre Hydrazine Tank Volume (net) 104 to 177 litres Propellant volume 78 litres (Blow down 4:1) Propellant Hydrazine (N2H4) MEOP 24.6 bar Proof pressure 36.9 bar (1.5 x MEOP) Burst pressure 49.2 bar (2 x MEOP) Mass 6.4 kg Pressurant gas Helium or nitrogen Goometry Spherical Interface fixation Pole mounting, rigidly fixed at propellant port boss.
