What importance did the V2 rocket have in World War 2?
The V-2 RocketIt is devoted to one of the most awesome weapons of WWII - the V-2 rocket. The V-2 or Aggregat 4, was the first long range ballistic missile to be actively used in combat. This huge German rocket hurtled a one-ton torpedo 50 miles high and hundreds of miles down range to its target.The fact that this achievement was the product of the ruthless system of government of Nazi Germany-and the fact that many thousands of people died as a result of its production and deployment-touch the image of what otherwise would be considered a monumental technological triumph.
What size was the rocket steam train?
one of the early model steam trains
What is a nuclear-tipped missiles?
A rocket or unmanned airplane with one or more nuclear warheads as its payload.
Magazine capacities of the Iowa class battleship?
The Iowa Class battleships had three main battery gun turrets, each with three guns. Two were forward and one aft. Turret Number Two, forward, was superimposed over the top of Number One. All propellant and projectiles were kept within the gun structure, which was actually five levels tall, all within a special round citadel armored with 15-inch thick special treatment steel, called a barbette. Turrets Number one and Three had a capacity to store 200 projectiles, plus propellant to fire them. Turret number two was one level taller and could store 240. Battleships were built to combat enemy battleships. For that purpose the guns fired armor-piercing shells, which weighed 2700 pounds each. The guns could also fire "high-capacity" (high explosive) bombardment shells, which weighed 1900 pounds each. When they were designed though it was contemplated that their main purpose and use would be to fight enemy ships, so they were designed to carry enough propellant to fire a full load of the heavier armor-piercing shells. It took 330 pounds of propellant to fire the lighter "high-capacity" shell and 660 pounds to fire the heavier armor piercing shell. Thus propellant storage was 66 tons each for Turrets One and Three and 79.2 tons for Turret Two, or a total of 211.2 tons. The propellant was stored on the lowest level of the five story gun structure and raised to the gun house by an elevator. For each type of shell six silk bags of propellant were used - 55 pound bags for the high-capacity shells, 110 pound bags for the armor piercing. The propellant was not actually powder, but nitro-cellulose, formed in round "grains" the thickness of a pencil, one and a quarter inches long, perforated with holes. For 55 pound bags these were dumped in the silk bag, for 110 pound bags they were stacked. Silk was used to insure complete combustion of the bag, to prevent flaming fragments from igniting the charge of the next shell when the gun was reloaded. This main battery arrangement was identical on all the ten "fast battleships" the US built just before and during WWII. These were the last battleships the US ever built, and included the North Carolina Class and the South Dakota Class, in addition to the Iowas. The only difference was the barrels of the Iowas guns were eight feet longer, giving them a slightly longer range. The six built before the Iowas, with shorter barrels, had a steeper "plunging trajectory" though, which was more useful for smashing through the armored decks of enemy battleships. The battleships also carried thousands of rounds for the secondary battery, which was twenty five inch guns, ten to a side, housed two each in five turrets on each side. It took seventy pounds of propellant to fire a shell from these guns. This propellant was stored in separate magazines.
One of the first propellant used was?
Gunpowderwas the first propellant used
What is a hybrid Rocket propellant?
A hybrid rocket is the rocket with a rocket motor that uses propellants in two different states of matter; one liquid or gas and one solid.
How is thrust created in space?
Thrust in space is created by expelling mass or propellant in one direction, following Newton's third law of motion which states that every action has an equal and opposite reaction. By expelling propellant at high speeds through a rocket engine, the rocket is pushed forward in the opposite direction, generating thrust.
What are the components of a rocket engine?
A rocket engine is made up of many unique different parts. The components of one include a nozzle, engine casing, delay charge, propellant, engine mount, and ejection charge.
What was one of the first propellant used for?
One of the first propellants used for rockets was gunpowder, which dates back to ancient China. Gunpowder, a mixture of sulfur, charcoal, and potassium nitrate, provided the explosive force needed to propel early rockets.
Is it possible to power a rocket using nuclear power?
Yes it is and NASA have various designs and projects to study the practicalities of such engines. Nuclear power may be used to heat a propellant, provide an electrical power source for an ion engine, or may be used directly to provide thrust in a number of ways, one example being the fission-fragment rocket.
Does a rocket works on principle of conservation of mass?
Yes, a rocket works on the principle of conservation of mass. It follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. By expelling mass (propellant) at high speed in one direction, the rocket is propelled in the opposite direction.
Why does a rocket move?
A rocket moves by expelling high-speed propellant gases through its engine nozzle in one direction, creating an equal and opposite reaction force that propels the rocket in the opposite direction, following Newton's third law of motion. This process is known as thrust generation.
Name the principal on which a rocket works?
The principle on which a rocket works is Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Rockets generate thrust by expelling propellant at high speeds in one direction, causing the rocket to move in the opposite direction.
Does the shape of the nose on a rocket affect how high it goes?
If the nose is pointy, the rocket will go faster, but if the rocket's nose is flat, it will just travel slower in the lower atmosphere, the height a rocket attains depends on the efficiancy of its engines, the amount of propellant carried and the launch profile. However, for a subsonic rocket (which is what most hobby rockets are) then a curved on not a pointy one is much better. I would suggest looking it up on wikipedia.
When was the stephensons rocket used?
Stephenson's Rocket was first used on the Liverpool and Manchester Railway in 1829. It is considered one of the earliest steam locomotives and played a significant role in the development of railway transportation.
What is the energy of rocket fuel?
enough
