Should be less than 1/5 length of main tube.

typically the nose cone is filled with a parachute to the rocket arrives on the ground safely.
It streamlines the nose, so the rocket flies faster.
"Rocket nose cone" pretty much says it all, I really don't think there is another suitable name.
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.

It streamlines the nose.
For a subsonic rocket, a rounded or ogive-shaped nose cone is often better. These shapes help minimize drag and improve aerodynamic efficiency, allowing for smoother airflow around the rocket. Additionally, they enhance stability during flight, which is crucial for maintaining a straight trajectory in subsonic conditions. A pointed nose cone, while beneficial at supersonic speeds, can create excessive drag at lower speeds.
A perfect cone
