Is There Any Real Proof That 9/11 Ever Happened?

I mean besides those obviously faked videos that showed an aluminium airplane MAGICALLY fly through a concrete and steel skyscraper? Or can we just chalk this up as another Illuminati hoax like the Moon Landings?

My goodness. Another troll with an account barely 1 day old weaving conspiracy theories? Why do I get the impression that you are a fanatic Muslim?

If you have a passion for rocketry or if you like to see your rocket soaring in the sky defying the gravitation of the Earth, it is imperative for you to learn some of the basic facts about model rocket motor. Watching a rocket taking off the ground is really a fascinating thing but knowing the science and the mechanics behind this captivating scenario will definitely make it far more enjoyable experience for you. So lets start learning some common facts about rocket engines:

Elements of Model Rocket Engines

In most of the cases, single used engines are integrated in those rockets, which use nozzles made of lightweight ceramic and cardboard bodies. Using lightweight materials helps a rocket to do away with unnecessary weight, which often acts as an obstacle. You are not authorized to any motor you want in your rocket. You have to make sure the fact the engine that you are going to integrate in your model rocket is certified and tested either by the Canadian Association of Rocketry, the Tripoli Rocketry Association or the National Association of Rocketry. Certified engine ensures safety that you should not discard at any cost. rocket engine motors can be broadly divided into two sections: F blackpowders motors and Blackpowder motors.

Black Powder Motor Engine

As black powder is very brittle in nature, you need to remain aware of all its minute aspects otherwise; you might have to face an untoward incident in near future. If you are using large black powder motor in your model rocket, you should never expose this motor to direct heat otherwise; it might develop hairline fractures in its body, which can have serious repercussion. Hairline fractures will increase propellant's surface area in due course of time, which can quicken the ignition process of the motor and thereby increasing the pressure in the engine's internal chamber. If the pressure becomes unbearable or if the pressures exceed the strength of paper case, it can tear apart the internal chamber of the motor engine and thereby causing massive explosion. The rocket might get partially damaged or it can be destroyed entirely.

Powerful Model Rocket Engine

The body of a powerful model rocket engine should be made of hard plastic as its propellants will be made of aluminium powder, potassium nitrate, ammonium perchlorate etc. The nature of this kind of propellant is more or less similar to that of used in space shuttle and therefore, it is not as brittle as black powder. This type of propellant is more powerful and it has the capacity to withstand rough condition.

Reloadable Composite-Propellant Motors

If you are concerned about the cost, you need to opt for reloadable composite-propellant motors. More often than not, these types of motors are used for commercial purpose. The major advantage of this rocket engine is that you can reuse and reload it as long as it is in good condition.
