Effects of Changes in Altitude on Thrust and Power Components

What are the effects of changes in altitude on thrust and power components?

a) Thrust required and power required decrease with altitude, while thrust available and power available increase. Excess thrust and excess power decrease.

b) Thrust required and power required increase with altitude, while thrust available and power available decrease. Excess thrust and excess power increase.

c) Thrust required increases, power required decreases with altitude. Thrust available increases, power available decreases. Excess thrust increases, excess power decreases.

d) Thrust required decreases, power required increases with altitude. Thrust available decreases, power available increases. Excess thrust decreases, excess power increases.

Final answer: Thrust required and power required increase with altitude, while thrust available and power available decrease. Excess thrust and excess power increase.

Answer:

The effects of changes in altitude on thrust and power components are as follows:

Thrust required and power required increase with altitude, while thrust available and power available decrease. Excess thrust and excess power increase with altitude.

As altitude increases, the air pressure decreases, leading to a decrease in the concentration of gases, including oxygen. This results in a reduction in the available thrust and power, as the rocket engine has less air to produce force and energy. However, the thrust and power required to overcome the reduced air density increase to ensure the rocket can maintain its velocity and altitude.
