| Abstract: |
| Under the same computational condition and total impulse, lateral dispersion from 2-stage-thrust rocket or 3-stage-thrust rocket is analysed with detailed data- It can be concluded that the lateral dispersion for 2-stage-thrust rocket is less than that for 3-stage-thrust rocket.Furthermore, the optimum switch time at which the dispersion approaches minimum can be obtainedfrom calculation. |
