| GETTING MORE THRUST | ||
Increasing exhaust gas velocity may be a more effective method of achieving higher thrust for some rocket applications. Increased velocity can be accomplished by either nozzle design or propellant selection. Increasing nozzle length can affect thrust by allowing the gases to expand to a higher exit velocity. However, this design approach does add weight due to the increased nozzle length and additional support structure. This results in a higher weight-higher thrust cycle similar to the mass flow method--although the cycle is not as severe and not as rapid an escalation. |
