What is the ratio for rocket fuel?

The weight ratio of oxidizer to fuel in the combustion chamber of a rocket engine. For example, the mixture ratio for the space shuttle’s main engine is 6:1, meaning six parts of oxidizer (liquid oxygen) to one part of fuel (liquid hydrogen).

What is the best fuel for a bottle rocket?

Use only rubbing alcohol (isopropyl alcohol) for the fuel. Other types of fuel may cause the bottle to explode.

What is the best ratio of water to air in a bottle rocket?

Q: How much water do you put in a water rocket? A: The simple answer is something less than half full. Since the compressed air stores the energy, and the water provides momentum, both are needed. Fill perhaps 40-50% of the motor volume with water.

What was the fuel used in the bottle rockets?

In this experiment, students observe as a ‘rocket’ made from a plastic fizzy drink bottle is filled with a mixture of hydrogen gas and air. The rocket is launched by igniting the mixture with an electric spark, and will fly several metres, propelled by the same reaction used to power the Space Shuttle.

Are homemade rockets legal?

There are many different methods for preparation of a sugar-based rocket propellant. In the United States, rocket candy motors are legal to make, but illegal to transport without a low explosives users permit.

Is Rocket Fuel expensive?

The fuel for a Falcon 9 (SpaceX) costs around $200,000 per launch, while the launch itself costs $62,000,000. Safety precautions, rocket shell and rocket engines cost a lot.

Is more water better for a bottle rocket?

The mass fraction of the rocket (mass of propellant/ total mass) will be close to 1, and the rocket will be very efficient. The more water you add, the more propellant you will have, and the higher the rocket will fly.

Who invented bottle rockets?

The first man to give hope to dreams of space travel is American Robert H. Goddard, who successfully launches the world’s first liquid-fueled rocket at Auburn, Massachusetts, on March 16, 1926. The rocket traveled for 2.5 seconds at a speed of about 60 mph, reaching an altitude of 41 feet and landing 184 feet away.

Are the forces on a rocket taking off balanced?

When a rocket is sitting on the launch pad and not moving, there are forces acting on it, but these forces are balanced. This means that the force pulling it downwards (gravity) is equal to the force pushing it upwards (support force of the ground). These forces are balanced.

Who invented water rockets?

Joanes de Fontana invented the first torpedo type rocket to destroy enemy ships. While most uses of rockets at this time were for war, there is a Chinese legend about an official named Wan-Hu, who supposedly built a rocket-powered flying chair propelled by 47 fire-arrow rockets.

Is it illegal to go to space by yourself?

Space is common ground and everyone is allowed to explore it. “Outer space shall be free for exploration and use by all States,” the Outer Space Treaty reads.

Is Rocket Candy illegal?

In the United States, rocket candy motors are legal to make, but illegal to transport without a low explosives users permit. Users may also launch using these motors by applying for an FAA flight waiver.

Which is the optimum mixture ratio for a rocket engine?

Optimum Mixture Ratio. A propellant’s optimum mixture ratio is a function of the pressures at which the rocket engine will operate. An engine with a high combustion chamber pressure and a low nozzle exit pressure, i.e. a large section ratio, will have the highest optimum mixture ratio.

How does a soda bottle make a rocket?

A straw is attached to the side of a two liter soda bottle to guide the rocket along the rail during ignition. The bottle cap is drilled to create a 3/8 inch hole which serves as the rocket nozzle. Two or three drops of rubbing alcohol are placed in the empty bottle and the bottle is shaken to mix the alcohol with the air in the bottle.

How is the nozzle of a rocket made?

The bottle cap is drilled to create a 3/8 inch hole which serves as the rocket nozzle. Two or three drops of rubbing alcohol are placed in the empty bottle and the bottle is shaken to mix the alcohol with the air in the bottle. The rocket is then slid unto the launch rail and an igniter is placed near the nozzle exit.

What kind of propellant does a whoosh rocket use?

The standard bottle rocket uses a two liter soda bottle as the frame of the rocket, and pressurized water as the propellant. The whoosh rocket replaces the heavy water with a much lighter, combustible, alcohol-air mixture. The pressurization of the bottle occurs during the combustion of the alcohol.
