There's no absolute maximum. In terms of model rockets, the only critical requirement is that it physically fits; in models like the old Estes X-Ray the nose was significantly larger in diameter than the body tube; a balsa adapter and a short mylar tube was used to mate the large nose with the smaller body tube. A large nose actually helps stabilize the rocket by moving the center of mass forward.
The only other thing to consider is that the larger the nose, the larger the mass (assuming it's constructed of the same material). This means that a given engine will not produce as great an acceleration, so your rocket will not go as high or as far as it would with a smaller nose.
Ideally, as wide as the bottle, tapering to a point
it depends on the size of the body tube
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.
It streamlines the rocket and allows more speed.
A streamlined plastic 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.
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.
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.
they use their big nose to survive in the wild by sniffing out prey and predator's. :D
Currently, we use the cargo space of rockets for satellites.
Everyone knows the reindeer Rudolph has a red nose. Santa's big red nose was redder after he was out in the cold.
It's a cone, and they use it because it is a very aerodynamic shape so the air doesn't resist the rocket going up as much
You must use a motor with 'retro fire' if you have a parachute. -At the apex of the flight, these motors fire a short burst into the rocket tube, and the expanding gases push the nose cone off so the parachute comes out and opens up.
When you start the big bully level star with a rocket boost then when he's at the edge use a mushroom to knock him down.
