To keep the rocket in straight,stable flight.
In a real rocket, there is short a time in atmosphere and the aerodynamics are less important. In a model rocket, all flight in the atmosphere and the aerodynamics are very important. In a real rocket, it has a liquid or solid rocket engine and a large propellant mass fraction. In a model rocket, it has a solid rocket engine and a small propellant mass fraction . In a real rocket, there are four forces during atmospheric flight. In a model rocket, there are four forces throughout flight. In a real rocket, there is a long powered flight . In a model rocket, it has a very short powered flight . In a real rocket, it has passive stability and active control . In a model rocket, it has passive stability and no control. In a real rocket, it has expensive materials such as aluminum, titanium, and nickel alloy. In a model rocket, it has inexpensive materials such as balsa, cardboard, and plastic. In a real model, there is a high speed and the heating is very important. In a model rocket there is low speed and the heating is not important.
it helps protect its cover
When model rockets get to the apogee of flight they separate or eject the nose cone to release the parachute that will let the rocket down without breaking it.When model rockets get to the apogee of flight they separate or eject the nose cone to release the parachute that will let the rocket down without breaking it.
Lift, drag, thrust, and gravity.
So that when it finishes it's flight and opens, you will see it easier by the streamer.
about one-forth of the height of the size of the rocket.
Weather plays a major part of a Model Rocket flight. Winds can force the rocket to curve sideways, known as windcocking. Higher moisture increases the density of the atmosphere, which can slow the rocket down. Temperature also can alter the flight of the rocket by: 1) Cold days - the air is denser, the rocket will be slightly slower, but more stable. 2) Warm/hot days - The air is less dense, the rocket will be slightly faster, but slightly less stable until it reaches a higher speed. There is plenty of things a model rocketeer can do to adjust to the weather. Tilt the rocket slightly into the wind to compensate for the recovery (winds will drag the rocket when the parachute is deployed), Finding a rocket with a lower Stability Factor to counteract the windcocking effect somewhat (slightly smaller guide fins). As for the temperature, there isn't much you can do to deal with that.
Balsa fins refer to the fins that are made for model rocketry and are cut from balsa wood. These are glued or cemented onto the base of the cylindrical part of the rocket. They are crucial to the flight stability of the rocket.
Indeed they do! There are a few primary forces that affect a rocket's flight, and one of those forces is drag. Aerodynamics is basically how drag affects an object in motion, and making something "more aerodynamic" means building it in such a way that it has less drag. The less drag something experiences, the faster (and in the case of model rockets, higher) it can go.
Modern model rocket fuel is a solid fuel.
