How many fin's should a rocket have?
It depends on a lot of stuffs like how much do you want your rocket to be stabile. But at least it must be 3. For example for the same stability you may have 3 fins that have large surface area or 4 which is smaller or more. When you increase the number of fins with the same surface area then the drag will increase because of the surface friction so 3 or 4 fins are generally used but there is no certain limit of the number of fins .
What is the best material to make fins of a rocket?
Carbon fiber or fiberglass are commonly used materials for making fins of a rocket. They are lightweight, strong, and provide good aerodynamic performance. It is important to consider the weight, strength, and stiffness of the material when choosing the best material for rocket fins.
What should you name your bottle rocket?
A person can name their bottle rocket anything that suits their preference. Good choices include Power, Fire, Fierce, and Boom.
How would you make a good bottle launcher?
# Remove the label from the outside of the bottle. Take a cloth and some paint thinner to remove the sticky portion of the label. This may take a while and a lot of rubbing. # Decide how many fins you would like. Four fins are easier than three, but if done correctly either way works well. The fin shape is also up to you. See the diagram for the easiest fin shape. Next, trace the fin design out on the balsa wood sheet and cut the desired number of fins out from the sheet. Make sure that the grain of the wood is running parallel to the leading or trailing edge of the fin. If this is not done, the fin may rip apart in mid flight. Lightly sand the fins so they become smooth. # Now, it is time to mount the fins onto the rocket. Take a piece of paper and wrap it around the lower portion of the bottle (near the opening end). Mark the circumference of the bottle where the piece of paper overlaps its self. Remove the paper and measure the distance to the mark that was just made. This will tell you the circumference of the bottle. If you are planning 4 fins, divide the circumference by 4. Use this number to divide the piece of paper into four equal sections and mark the sections. If you are planning for 3 fins, use the same process, but this time divide the piece of paper into 3 sections. Wrap the piece of paper around the bottle as before and secure it with a piece of tape. Take a felt marker and transfer the section marks on the paper to the bottle. These marks designate where the fins are to be placed. Make sure everything is perfectly even, or the rocket will not fly well. # Next, take a straight edge (ruler) and draw a line through the mark that was made so you will have a guide-line for fin mounting. Apply a rubber-based cement to the fins, carefully aligning the fins with the straight lines you have just drawn. Press the fins down onto the bottle and use a piece of tape on either side of the fins in order to keep them straight while the glue sets. It is best if only one fin is done at a time and the fin is kept vertical until the glue has set. Make sure all of the fins are perfectly straight. # The final step is to cut the manila folder into a cone so that it will fit over the top of the bottle rocket. This will be the nose cone. Cement the nose cone to the top of the rocket. If you wish, a parachute can be added. The rocket is now finished. Make sure all glues have dried completely and the fins a securely attached to the rocket before it is flown.
How do you make a rocket fly?
Get a huge bottle of soft drink (Cokes good), place mentos inside and shake bottle. leave the lid on loosely. Place a rocket on top, then, watch it fly!!
How much water do you need for a 2liter bottle rocket?
i think about 220 would be a good amount
Why is it not a good idea to assume that the mass is constant in a bottle rocket?
Assuming that mass is constant in a bottle rocket is not ideal because as the rocket fuel is burned and expelled, the mass of the rocket decreases, leading to changes in its acceleration and velocity. This can impact the accuracy of predictions related to the rocket's trajectory and performance. Taking into account the changing mass allows for more precise calculations and design considerations.
How do rocket parts affect flight?
AnswerThe fins on a rocket are just there to create stability. As long as there are enough to provide a restoring force against a disturbance, it shouldn't matter. But ...Enough means at least three, symetrically placed, with enough area so that when the rocket tips off of its path a little bit the fins provide aerodynamic force to put it straight again. If you only had two, a disturbance in the plane of the fins would not get corrected and the rocket would veer off course. With three, any tipping off of the flight path hits at least one of the fins in a way to correct the misalignment. Four works, too. Any more than that and you're just adding drag, which will shorten the flight.Note well that the key parameter is the area of the fin times the distance it's lift center is behind the mass center of the rocket. That's why something with the fins behind the engine nozzle works so well, because the lift center is behind the entire rocket. Before I knew that rule I built a seriously overpowered rocket with gigantic fins that came all the way up to the nose. Instead of flying with great stability as I expected, it jumped off the launch rod and headed for launch control, then writhed on the ground like a beached whale until the parachute charge went off.
What are some good model rocket suplies?
To build a model rocket you will need a chemical rocket engine, some cardboard tubes, glue, a long rubberband, a garbage bag and a lot more. You can find a complete list of supplies here: http://www.ehow.com/how_2308899_build-model-rocket.html
What is the perfect amount of water you should put in a 2liter bottle rocket?
A good rule of thumb is to fill the bottle about one-third to one-half full with water before launching the rocket. This amount of water provides enough mass for propulsion, but not too much that it affects the rocket's flight. Experimenting with different water levels can help you find the perfect amount for your specific rocket design.
Is cardboard good for making paper rockets?
I would say yes, because cardboard material is sturdy enough to hold the rocket in shape and it is flexible enough to curve into a cylindrical shape.
How much would a Wayne Gretzky stand up 6 foot tall cardboard picture holding a bottle of Coke in his Kings uniform be worth?
A Wayne Gretzky stand up 6 foot tall cardboard cutout holding a bottle of Coke in his Kings uniform sells for about $90. This is providing the cutout is in good condition with no rips, creases, fading, or stains.
