Stability of Model Rockets

Stability

1. When a rocket encounters gusts of wind, or thrust instabilities, as it flies through the air it will rotate around what point in the rocket?
- When the rocket encounters gusts of wind, or thrust instabilities as it lies through the air, it will rotate around the center of pressure

2. How does a rocket produce aerodynamic lift and through what point do both the lift and drag forces act?
- Rockets produce aerodynamic thrust through the angle of attack and the engines thrust. Lift and drag are prouduced from the center of pressure

3. In order for a rocket to be stable does the center of pressure or the center of gravity have to be located behind the other in order to produce the required restoring force?
- What happens if their positions are reversed?In order for a rocket to be stable the center of pressure has to be behind the center of gravity. If these positions were reversed then the rocket would not be stable and crash during flight

4. Unlike a model rocket, many modern rockets such as the Delta, Titan, and Atlas boosters do not have fins. How do these rockets remain stable in flight?
- Modern rockets that do not have fins on the boosters tay stable during flight because their boosters are larger than the main part so it stays stable during flight

5. Why is it more difficult to analyze the interactive forces between a solid object traveling through a fluid than for two solid objects?
- It is more difficult to analyze the interactive forces between a fluid and solid object rather than two solid objects beacuase the solid and fluid are two different substances which makes it harder to analyze, when the two solid objects are the same and therefore the forces are easier to see because they are the same

6. Name and describe the impact each of the three major aerodynamic factors.
- The three major aerodynamic forces are lift, drag, and thrust. Lift is the force that makes the rocket fly. Thrust is the force that propels the rocket from the launch pad. Drag is the force that helps slow down the rocket on its return

7. Describe the impact of an applied force to both the change in position of the rocket’s center of gravity (translation in space) and its change in orientation around the center of gravity (rotation in space) when it is through the center of gravity or through any other place on the rocket.
- If a force is applied to the center of gravity or any other point in the rocket then the rocket would become unstable

8. Describe torque, its impact on the motion of a rocket, and the role of the rocket’s fins in generating stabilizing torque.
- Torque is the power of acceleration. The more torque the rocket has, the more it accelerates in the air. The fins of the rocket help make the rocket stable when the rocket accelerates.

9. Describe what happens to the orientation and translation of the rocket when there is a wind during the launch. Will the rocket turn upwind (into the wind) or downwind (with the wind)?
- If there is wind during the launch and flight of the rocket, the rocket will turn with the wind.

10. What effect does a wind have on the maximum altitude that a rocket can achieve?
- If there is wind during the flight, this will cause more drag to the rocket and therefore it wont be able to go as high.
