Rockets and Missiles-IA1

Rocket working principle is conservation of

• Mass

• Energy

• Linear Momentum

• Entropy

Hypergolicit process doesn't require

• fuel

• oxidizer

• High Chamber Pressure

• Igniter

In the equation $r=aP_c^n$ , find the inappropriate from the following

• negative slope is possible

• regression rate is higher at the steady state condition

• Burning is normal to the fuel surface

• High regressive fuel has high 'r' value

Ignition process is defined as

• Onset of first smoke

• Onset of the first luminous spark

• Onset of steady state condition

• Onset of regression
