Example 10, Slide 9: GENOPT/BIGBOSOR4 lateral-pitching vibration modes: (C) Primarily lateral tank motion and (D) primarily tilting tank motion

Fig. 4 from the 2013 GENOPT paper2. (continued) Two more vibration modes from GENOPT/BIGBOSOR4 for the optimized propellant tank with one skirt attached at the midlength of the cylindrical part of the tank. These are both lateral-pitching vibration modes (n = 1 circumferential waves). (C) Primarily horizontal translation of the propellant tank; (D) Primarily tilting motion of the propellant tank. Compare with predictions from STAGS shown in Figs.5a,b
