Part 1- Tumble Glider
Above wing: There is high velocity going above the wing with low pressure.
Under wing: There is low velocity going under the wing with high pressure.
- The trajectory
- The force is acting on the rocket at the moment of launch
- The rocket was half-way up, which force(s) is/are acting on the rocket
- The rocket begins to veer into another direction
- Explanation of the whole project
Acceleration: the capacity when a vehicle gain speed in a short time
Center of drag: when pressure force an object to act through that point.
Center of mass: represents a point of an object’s position
Drag (physics): a force that is caused by air.
Inertia: the uniform motion (travels equal distances in equal intervals of time) in a straight line
Mass: The weight of a large body
Momentum: The motion of a moving body (measured as a product of mass and velocity)
Pressure: The physical force exerted on or against an object
Velocity: The speed of something in a given direction
1. How did the height you estimated your rocket would reach compare with the actual
Estimate: 50 ft
Actual: 45 ft
2. What do you think might have caused any differences in the height you achieved?
I believe that I could improve my rocket’s height by making the wings more thicker and make the bottle more air dimension.
3. Did your rocket launch straight up? If not, why do you think it veered off course?
My rocket did not launch straight up because my wings were too weak and the air dimension was not as good as it was.
4. Do you think that this activity was more rewarding to do as a team, or would you have
preferred to work alone on it? Why?
I like the project and it was rewarding because it showed me my failure of the rocket and how I could improve.
5. Did you adjust your model rocket at all? How? Do you think this helped or hindered
I have not adjust my model rocket because we had no time; however, I would of change my wings and the shape of how it looks because the air dynamic was terrible.
6. How do you think the rocket would have behaved differently if it were launched in a
It would have launched straight up but start to swerve towards a direction.
7. What safety measures do you think engineers consider when launching a real rocket?
Consider the location of most launch sites as part of your answer
- Location: they need an area where the environment is life less. (close to the ocean)
- The rocket stiffness: if the rocket’s material is not strong enough, the astronauts might die because the pressure would collapse on them.
- Material: the material they use in/out of the rocket needs to be safe for everyone.
8. When engineers are designing a rocket which will carry people in addition to cargo, how
do you think the rocket will change in terms of structural design, functionality, and
The structural design would make sure the people inside will be safe (not too small or too thin). The functionality would be the quickness of the launch of the rocket and the features like sleeping area are needed so they would need to make the design big enough that they can have a normal life inside a rocket.
9. Do you think rocket designs will change a great deal over the next ten years? How?
Yes, since the modern day rockets can not make to other planets with humans in it. As a result, with different rocket designs, they would probably be able to launch and arrive to an other planet.
10. What trade offs do engineers have to make when considering the space/weight of fuel
vs. the weight of cargo?
They need to consider the pressure and the elements (hydrogen, helium) in space.
