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.

How will you reduce drag forces in your bottle rocket?
the aerodynamics of the bottle can be increased or the bottle can be smoothened on all the sides therby increasing the aerodynamics therby decreasing the drag of the vehicle
What does the recovery system do on a model rocket?
It basically allows you to reuse your rocket. Common recovery systems are a parachute or a streamer, both of which pop out of part of the rocket (the nose, usually) when it's in the air. The parachute (usually used with slightly larger rockets) or the streamer (generally found on smaller rockets) then catches the wind/air as the rocket comes down, allowing it to land without damage.
What causes nose cones on rockets to separate?
The nose cone separates when forward flight is ended and the motor 'retrofires', blowing off the nose cone and exposing the parachute.
What does the fire-retardant wadding in a model rocket protect?
It generally protects the recovery system. If you sit a parachute or streamer on top of a hot engine, it's going to melt or burn up (depending on the material). The wadding is placed between the engine and the recovery system so your rocket will work like it's supposed to and you'll be able to reuse it. You have to be careful how tightly you put in the wadding, though, since you don't want it to stifle your engine.
What are some of the jobs rockets do now?
Rockets now send people to the moon, take pictures of things in space, and fix satellites.
Why aren't the fins in the front of a rocket?
The further forward rocket fins are, the more they tend to steer it. You could mount fins at the front, but they would have to be incredibly straight and parallel for your rocket to fly straight.
One of the worlds most famous anti aircraft missiles, the Sidewinder, has 4 small steering fins near it's nose. While it was being developed they found if these fins moved too quickly the main tube would actually twist and destroy itself !
How high does a B6-2 model rocket engine fly?
Depends on the weight and streamlining of the rocket. i regularly get a B6 up to an estimated 1,500 feet.
Recovery wadding is a flame-resistant tissue paper placed in the tube of a model rocket before the recovery device and nosecone. Its purpose is to prevent the parachute or streamer from being burned / melted when the ejection charge goes off.
What is a cargo that rides in the nose of a rocket?
Currently, we use the cargo space of rockets for satellites.
How do you make a heat shield out of just tin foil and a wire grate?
Model rockets do not need heat shields, they don't move fast enough for air friction heating to be a problem.
How many charges are in a A8-3 single stage engine of a rocket?
One propulsion charge and one ejection charge.
Is the parabola nose cone the best for a model rocket?
Yes. For rockets flying at supersponic or hypersonic speeds, the best shape is the conical nose. For missiles and military models, the best shape is the ogive shape. However, for commercial aircraft and model rockets, the best, most aerodynamic and efficient shape is the parabolic nose cone.
Can you use regular white paper for a model rocket?
No, it isn't strong enough. Find light cardboard rolls as come inside rolls of kitchen tinfoil, or wax paper.
What are some negative things to shooting off a rocket?
Rockets can be expensive to build and technically challenging. If they fly off track they can hit and damage objects or people of if they are big enough cause an international incident. If they blow up the explosion or the remaining burning fuel can be toxic and start fires.
What is the best parachute for a model rocket to float to the ground slowly?
A big one, but that will also be blown in any transient winds, so you have to compromise.
You can build a rocket in various ways... One way that you ca build a rocket is using bottles...
A bottle rocket.
use a straw and some stiks and some paper
Who invented the rocket locomotive?
Robert Stephenson invented the Rocket locomotive in Newcastle, England in 1829
If you leave your Pokemon emerald on all night will the space rocket count go up?
No coz the rocket lauches change once a week sorry but i have to wait
Answerdon't care AnswerI don't think so I think it only go's up once you have defeated the elite four.After you have SMASHED them 100 times the man in the rocket place says would you like to go on please say yes because that's where you will catch jirachi!it adds every hour after you beat the elite four the first time
