Q:
Which of the following can’t happen if a chemical rocket engine were to use gelled propellants?
Answer & Explanation
Answer: A) Increase in specific impulse
Explanation: Depending upon the gelling agent, specific impulse might change. Because of the dilution of the propellants with a gelling agent, there is generally a small decrease in specific impulse. It will also lead to less efficient atomization or combustion.
