Model Rockets
Model rockets are made or assembled by hand, and propelled by a variety of means; the hobby can be quite simple, or very involved. This category will cover the information and skill levels on making and launching model rockets.
270 Questions
Why the rocket nose cone becomes very hot when it re-enters the atmosphere?
Due to the friction when the rocket re-enters atmosphere .the hotness comes because the work is done again frictional force
This does not happen on model rockets,of course.
What is the part of a rocket that is discarded?
In model rockets, the only part that is discarded is the actual motor casing. Everything else is re-usable provided it lands in good shape.
What two forces slow rocket down when out of fuel?
inertia and friction are the two forces that slow down a rocket
Does the leingth of the cone of a rocket make a difference in its flight?
Yes very much so. All the rockets I have made flew better when the cone was made longer. But it works way better to have it dead center not crooked.
Does the body tube on a rocket affect it?
The body tube of a rocket is there for friction. As the rocket comes back down the body tube along with the fins are there to slow it down. Also the longer the body tube the faster your rocket will go. The body tube gives it a narrow edge.
What do you mean by Styrofoam balls?
Small balls made of styrofoam. Craft stores sell them in various sizes.
What form of mass is a rocket engine throwing'?
pressure it thros pressure mass and benifts from the reaction
Is it better to put the parachute inside the nose cone or around the outside?
The parachute should be stored inside the airframe, or, "body" of your rocket. Locating it outside of the rocket would cause it to deploy on lift-off, resulting in CATO. The chute must be secured to an anchor inside the shoulder of the nose cone. Apogee.com has several learning tutorials that would benefit you greatly.
How many feet are in 1 degree of latitude?
One degree of latitude is 69.06 miles. With this information, and knowing that there are 5,280 feet in a mile, this becomes a simple arithmetic problem.
What are the types and shapes of nose cones on rockets?
Nosecones can be almost any shape and any material imaginable. Even a cube shaped nose cone can fly straight with ease. Typical cone shapes include "ogive" and "conical". They are typically made of balsa wood, plastic, and fiberglass/carbon fiber. An odd shaped nosecone can be offset by fins that are adequate to compensate for the the shape of the cone. One high-powered rocket, named "Suicide King" as seen on youtube, actually flew without a nose cone for a nearly perfect vertical flight.
Aries was a rocket used for low altitude flights, so less than 6000 km/sec. Aries Orion (or just Orion) is a spacecraft that will take us to the Moon, so close to Earth's escape velocity of about 11200 km/sec.
On a pop bottle rocket how should the fins be cut?
They should be cut into triangles and place perpendicular to the rocket. This will give it greater stability when if flies into the air. Place the narrowest part of the triangle towards the top of the bottle and the widest part towards the bottom.
How fast are you allowed to go when passing another vehicle?
i recently read you are allowed 5 mph over or under the posted speed limit. and also that when you are legally passing a vehical you must got 10mph faster then the car you are trying to pass. is this true???
What type of engine does a model rocket use?
Most hobby rockets engines are constructed of wood, plastic or paper, many different kinds of accelerates can be used.
Please see related links below. There is gunpowder in the engine
How do you give a model rocket less drift?
You really can't . The wind is what makes it drift and you have no way of knowing what the wind is like at 300- 5,000 feet.
Does weight on model rockets matter?
Yes it does. The more weight that there is in the rocket, the more energy it takes to lift off. Its the same as if you raised your hand above your head and it's empty. Put a ten pound weight in it and you have to exert more energy to lift it.
How is a rocket engine different from that of a car engine?
A rocket motor propels by vectoring the exhaust to produce thrust, whereas a piston engine uses the motion of the crankshaft to turn gears in order to put a vehicle into motion. The piston engine also has significantly more moving parts.
since the rockets are supposed to carry the oxygen (required for burning the fuel) of their own, oxidizer comes here into the scene as it is the one which provides that oxygen. in case of a turbojet engine or a simple automobile engine, this oxygen is sucked into the engine as air but in case of rockets as they have to travel in space (obviously no air there so no oxygen) they carry with them the amount of oxygen which will be required to burn the loaded fuel to produce exhaust gases which in turn provides thrust to the rocket...... the oxidizer can be in liquid or solid state depending upon the type of rocket i.e solid, liquid or hybrid rocket..... some typical examples are AMMONIUM PERCHLORATE, AMMONIUM NITRATE, AMMONIUM DINITRAMIDE, HYDRAZINE, NITROUS OXIDE, HYDROGEN PEROXIDE, POTASSIUM PERCHLORATE, LIQUID OXYGEN (BEST ONE).......
Except for LIQUID OXYGEN the above mentioned oxidizers liberate OXYGEN when heated... this liberated oxygen is used for the combustion of fuel....
I Hope I were clear and of help....
Can the smoke from a model rocket kill you?
Probably not, but I wouldn't recommend standing too close to the rocket as it lifts off. The fumes from the rocket's engine definitely aren't very good for your lungs.
