How does a nose cone help a rocket fly ?

Question

I have a D.T. homework about air rockets and I want to know about air rockets. If you know please tell me.

Answer 1

It's all to do with aerodynamics, the nose cone pushes the air in front of it out of the way and away from the sides of the vehicle.

Answer 2

The nose cone helps a rocket fly because it's very aerodynamic. It's based on the principle of wind resistance. Imagine a rocket that had a nose that looked like a brick. As it flies, the air would slow it down because the wind would be striking a flat surface and would then have to go around that flat surface. Not very efficient at all, and at high velocity the wind could really wreak havoc with the rocket's direction -- and precision is CRUCIAL in rocket technology. The nose cone is designed to make the air go by the rocket in the most efficient manner possible. It's not perfect (no aerodynamic design is), but it's the best at keeping the rocket flying at top speed and helping to keep it on course.

Answer 3

All model rockets have the following parts: (1) One or more body tubes, the long round tube that holds the engine and payload, (2) a nose cone to reduce air resistance and provide stability, (3) fins to provide stability in flight, (4) an engine to power it, (5) a launch lug, and a (6) a recovery system. The more complex rockets may have several body tubes connected by tube couplers.

There are several phases to the rocket's flight. The first is the thrust phase. It is during this time that the impulse section of the engine burns. Once it has exhausted, the coasting phase begins. The engine is still active, but it is burning smoke, permitting you to follow the flight. The rocket is still climbing, using its momentum. Then, the Ejection charge ignites, which actives the recovery system. This is usually a parachute to permit the slow descent of the rocket, or it can be a streamer so that you can follow its path. Recover the rocket, install a new engine, then launch again.

All this info is about conventional rockets...I have found a good site for you to look at for water fockets but it gives you a good idea about other rockets and how they work

I hoper this has helped

Answer 4

To give you a visual idea of how a nose cone helps, think of sitting in a bath tub or pool. Now, if you were to try to push something flat on the front, say a block, through the water, you'd have a harder time, because the flat side of the block means you're pushing more water "forward." But if you were to try to push a football through the water, the the cone pointed away, it'd go smoother, because the cone allows the water to move around the football. Same thing with a rocket in the air, since water and air both move in a fluid way.

Answer 5

Because the nose has a point it creates equal air pressure on all sides and therefore helps to keep the rocket stable and heading in a straight line. It also helps to reduce drag caused by friction with the air which means it can travel further, faster and use less fuel.

Answer 6

.The cone decreases the surface area of rocket which suffers air resistance. The come spreads the resistance and thus helps to reduce it. If the cone was replaced by a flat surface, the area suffering resistance and thus the total resistance would increase. This would even be dangerous as it may trigger the rocket to lose its path due to the wind.

Answer 7

The nose cone is designed to cut through the air thus allowing the rocket to move smoothly and more efficiently as its body mass follows.

Answer 8

Google 'Air rockets' I just did it for you and loads come up so you're best going on yourself and have a look what is relevant so people don't give you the wrong answer.

Hope that helps

Good luck

Answer 9

ask the rocket fly

Answer 10

it doesnt technically, it simply aids with aerodynamics, cutting through the air and therefore less resistance / drag
