The 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.
Fins on a rocket affects its flight by the way they are built on the rocket
Incredibly ! -In rocket flight streamlining is the single most important factor.
it helps protect its cover
TwoIts not going to affect your home value much.they affect the stability of th rocket flightAntarctica is not on any commercial flight paths
Weight is a killer in terms of altitude.
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.
While a nose cone can either reduce or add drag, it provides a minimal amount of stability to the rocket' flight path. The fins are the most critical component for stabilizing a rocket's flight path; that's where your focus should be.
A small rocket might go higher because a smaller rocket has less weight
Of course. Your construction and fin alignment must be as near perfect as you can make it.
One of the key factors in rocketry is the weight of the rocket. By designing a rocket that ejects parts of the rocket that has emptied it's fuel tanks decreases the overall weght of the rocket, extending the flight of the rocket.
A plane needs air, a rocket doesn't.
The most important parts of a rocket are the payload (what the rocket is carrying), the propulsion system (engines and fuel), the guidance system (to control the rocket's flight path), and the structural components (body, fins, and nose cone) that hold everything together and provide stability.
