You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.

How do you built a rocket?
You use a Launch Lug, Parachute, Removable Solid Rocket Engine, Parachute Lines, Fins, Body Tubes, Nose Cone Payload (removable), Engine Mount (fixed), Shock cord, and Recovery Wadding.
How many fins should you put on a long range bottle rocket?
easy! get some balsa wood and a modeling knife!and cut out a simple shape!balsa wood is ok because it is light in weight, however, if your rocket has a crash landing the fins will not likely survive. I suggest something a bit more sturdy. on some rockets i have used chucks of CDs as fin material (they're harder to snap than you would think) i would also suggest arrow glue ( like the glue for archery arrows) as an adhesive for fins shape? i would check out this web site. the fin designs are not difficult to create and the shape is backed up by the Reynolds number don't know if you know any thing about that http://www.apogeerockets.com/technical_publication_16.asp.best of luck! :]

What is a good bottle rocket design?
Well, I reccoment a small bit of C4, but if you do nothave high explosives, then use an acid-base solution. Use a packet of paper towel or a capsule that melts in water and fill it with baking powder. Pour a bit of vinegar in the bottle, and then put in the capsule. put a cork with a stick on the bottom, and then, you are ready to go!
Are long or short and stiff or flexible fins most efficient when swimming while pulling a raft behind?
this is totally a personal preference. i love my very short FORCE FINS but others love their very long freeDiving fins. many factors influence a person fin preference because of individuals swimming preference, FORCE FINS use more of the calf muscle similar to short bicycle strokes, whereas a paif of long freeDiving fins use more of the whole leg. if you ask me; FORCE FINS if you ask my dive buddy: Apollo Bio-fins somebody else; a completely different answer in general though, universally; the SCUBAPRO JET FINS is the most powerful fin

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.
What is use of nose cone in rocket?
It streamlines the rocket and allows more speed.
What materials should you use to make a nose cone?
You would need 6 to 7 construction papers to make a nose cone on a bottle rocket. You would also probably need scissors and a ruler for measurement. You would also need tape for taping on the construction paper. Then just shape the construction papers into a cone and tape it on the bottle rocket.
What do you use for fins on a hydro rocket?
wht can i use for fins on a hydro rocket?? i am a student and i need help you can try cardboard, plastic, or cut CDs. they need to boe in triangles to fly high.
Why use parallelogram fins for a rocket?
There the most aerodynamic of fin shapes.
How do you put a parachute on a bottle rocket?
The best method is to tape the parachute to the side of the bottle and stuff it inside of the nose cone. The nose cone should have string connecting it to the rocket, yet, the nose cone is not actually taped to the bottle. It should balance on: a) Tabs (Cardboard) b) Just have it firmly on top of the top of the bottle This way, the rocket will soar straight up (hopefully), the nose cone will detach (but stay connected), the parachute will fill up with air and expand, and your successful rocket will sink to the ground at about 2-6 mph.
Do rockets have wing?
A rocket is a form of propulsion. If a rocket is used to power an airplane, it is referred to as a rocket-plane, and has wings like an airplane. It the rocket is use to propel a vehicle vertically, which does not need wicgs to provide lift, it is called simply a rocket. Sometimes fins are used to stabilize or guide a rocket in flight, but these are referred to as fins rather than wings.
What is the best nose cone to use for a model rocket moving at 90 miles per hour?
A streamlined plastic nose cone.
Will a bottle rocket fly with out water?
Yes if you use compressed air inside the rocket. Or you can use agitated methanol and a flame for thrust like a whoosh rocket.
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.
