Principles Of Flight

Part 1 – Tumble Glider

The wing is shaped so that the air flows faster over the top of the wing and slower underneath. Fast moving air equals low air pressure while slow moving air equals high air pressure. Since the pressure is greater under the wing the wing is pushed upwards.

Part 2 – Paper Rocket

1.
2. The forces that were acting on the moment of the launch is lift, thrust, weight, drag
3. As the rocket was half-way up, the forces are weight and drag
4. The forces that were acting when it veered into another direction is gravity and weight because the gravity is pulling one side down that is heavier
5.   Yes, others worked better than mine, the thinner the cone the less drag meaning that it would be more aerodynamic and if the cone is crooked to one direction, the rocket would go more on that direction. Thrust is the pressure built underneath the rocket. Lift is when the rockets start to go up. Weight is how heavy the rocket is. Drag is the wind slowing down the rocket because of some parts on the isn’t aerodynamic

Maximum height and speed is 7450m and 358 m/s
Mass = 5kg    Thrust = 400 N   Thrust Time = 5s

It flings around because of gravity of the planet                                                                                                                      Orbit is an object or a spacecraft path that goes around a planet, stars, or the moon

Co-efficient of drag is the ratio of the drag on a body moving through air to the product of the velocity and surface area of the body.

Attitude = 208.2   Velocity = 39.2  Flight time = 7.2                                                                                                                    Cone style = /\   Nose Weight = 0.3    Body Weight = 0.8     Tail Weight = 0.8    Water oz. = 32   Pressure PSI = 100

 

Part 3 – Bottle Rocket

What have you learned about the history of rockets and space travel? Write a summary on the blog about something or someone you found interesting and tell why.

I learned that in 1957 the Soviet Union shocked the world by launching the worlds first Earth-Orbiting satellite called the sputnik. Also, I thought it was interesting that the Soviet Union sent a dog named Laika the very first animal to be sent into space.

Now that you know about the basic parts of a rocket and what they do, write about each part and its importance in your own words. What will be different on your water rocket than on a “real” rocket and why?

The nose cone is a very important part of the rocket, it pushes the rocket through the atmosphere and reduces drag. The shaped would be the same as the real one, but it wouldn’t be as big and heavy as the water bottle rocket. The payload isn’t always necessary for the rocket but it is usually the reason why the rocket was built. The payload is used to carry animals, humans, scientific equipment, satellites, warheads, etc, into the air or space but my rocket would have an egg. The propulsion chamber holds the propulsion system. It has all the parts that make up a rocket’s engine; tanks, fuels, pumps, combustion chamber, and nozzle. Liquid propelled rockets usually had 2 tanks; one for the fuel and one for the oxidizer necessary for the fuel to burn. The pumps give the fuels and oxidizer into the combustion chamber where they are mixed and exploded. The explosion, or combustion, produces hot exhaust which is passed through the nozzle and makes thrust. What’s different from the real one is I will be using water as fuel and air for pressure. The fins help the rocket fly straight and it stabilizes the rocket during the flight. Without the fins, the rocket would tumble and not fly correctly. There wouldn’t be anything different from mine except being smaller and made out of cardboard.

Write a little on the blog about how to find the Center of Pressure and the Center of Gravity on your rocket and why they are important.

Get a piece of cardboard that slightly bigger than your rocket on all sides. Trace a line around your rocket as tightly as possible. Get ruler to use as a pivot point. Balance the cut out on a ruler than mark the same location on your actual ruler. That’s the center pressure of your rocket. To find the center of gravity of your rocket is to first tie a piece of string around the body of your rocket somewhere near the middle. Use tape so the string does not slip. Holding the rocket by the string, see if it balances. If it doesn’t balance, move the string towards the nose or the fins until the rocket balances. It is important because it will balance the rocket during flight and wouldn’t tumble, also it causes your rocket to fly further, faster, and under control.

Based on what you have learned about rocket design (nose cone & fins) describe what your rocket will look like and why you chose that design on the blog.
I would have a nose cone to have less drag, and put fins on the bottom to stabilize the rocket during the flight
Water Bottle Rocket Reflection

1. How did the height you estimated your rocket would reach compare with the actual
estimated height?                                                                                                                                                                    I estimated that the rocket would reach higher than my actual height                

2. What do you think might have caused any differences in the height you achieved?                                                      I think my parachute deployed earlier than anticipated so it didn’t reach the height it could

3. Did your rocket launch straight up? If not, why do you think it veered off course?                                                      Mine went straight up but than then it slightly tilted to the side but not much

4. Do you think that this activity was more rewarding to do alone? Would you have preferred to do it in groups? Why or why not?                                                                                                                                                                       Yea I would think it would be more rewarding when you do it alone because when you do well, you would feel like you did everything instead of relying upon your group

5. Did you adjust your model rocket at all? How? Do you think this helped or hindered
your results?                                                                                                                                                                              I made the wings straight to stabilized the flight of the rocket and so it won’t veering into another direction that much

6. How do you think the rocket would have behaved differently if it were launched in a
weightless atmosphere?                                                                                                                                                          It would go higher, farther, but I might not launch as fast when it thrusts and it would float up         

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.                                                                                      Maybe the weight, enough thrust to boost to the atmosphere, wings on the side so it won’t veer into other directions, and the parachute or some sort of landing device

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
features?                                                                                                                                                                                    First, the rocket would be larger, than you have to include more fuel and thrust because of the extra weight, and maybe more aerodynamics
9. Do you think rocket designs will change a great deal over the next ten years? How?                                                    Yea, with the advanced technology, the rocket would change a lot. Maybe it would be a more sleek design, everything would be more tight and agile, and maybe it would reach a longer distance

10. What tradeoffs do engineers have to make when considering the space/weight of fuel
vs. the weight of cargo?                                                                                                                                                              They have to make sure the fuel would make up for the weight of the cargo and the weight of the itself
