Example 10, Slide 17: GENOPT/BIGBOSOR4 lateral-pitching vibration modes: (C) Primarily lateral tank motion and (D) primarily tilting tank motion

Fig. 9 from the 2013 GENOPT paper2. (continued) Two more vibration modes from GENOPT/BIGBOSOR4 for the optimized propellant tank with two skirts attached to the tank at the aft and forward cylinder-dome junctions. (These are both lateral-pitching vibration modes (n = 1 circumferential waves). (C) Primarily horizontal translation of the propellant tank; (B) Primarily tilting motion of the propellant tank. Compare the GENOPT/BIGBOSOR4 predictions in this slide with predictions from STAGS shown in Figs. 10b.
