What is the formula for rocket fuel?
Rocket engines and boosters carry both fuel and an oxidizer. For solid fuel, the components are aluminum and ammonium perchlorate. For liquid fuel, the components are liquid hydrogen and liquid oxygen. When combined, the fuels release water, which allows the rocket to leave the ground.
How do you calculate the velocity of a rocket?
The resultant force is the thrust – weight = 5 – 0.49 = 4.51 N (unrounded). Acceleration = resultant force divided by mass = 4.51 ÷ 0.050 = 90 metres per second squared (90 m/s2). This means that, every second, the speed of the rocket increases by 90 m/s. This is nine times the normal acceleration due to gravity.
Who made the rocket equation?
Is Rocket Fuel expensive?
Rocket fuel cost about $100 per ton, perhaps $120 per ton. Oxygen cost about the same. (Assuming the fuel is methane or RP-1, hydrogen is a little more expensive.) So, the fuel + oxygen cost of a typical rocket that has 1000 tons of rocket propellant (fuel + oxygen) is about $100,000.
What rocket fuel does SpaceX use?
Merlin. Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use a rocket grade kerosene (RP-1) and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for recovery and reuse.
What is the velocity of a rocket?
The mass of the rocket just as it runs out of fuel is 75,000-kg, and its exhaust velocity is 2.40 × 103 m/s. Assume that the acceleration of gravity is the same as on Earth’s surface (9.80 m/s2).
How high will a rocket go?
Sounding rockets can travel much higher than weather balloons (another way of measuring the atmosphere), which can only travel up to an altitude of 40 km. Some sounding rockets travel up to 950 km or higher before falling back to Earth.
How heavy is a rocket?
The rocket could launch payloads of up to 45 tons to the moon, or 120 tons into Earth orbit. It weighed 6.5 million pounds (3 million kg) fully fueled at liftoff. The Ares I-X weighs 1.8 million pounds (816,466 kg), slightly less than the full Ares I rocket.
How much fuel is needed for a rocket?
The Saturn V rocket’s first stage carries 203,400 gallons (770,000 liters) of kerosene fuel and 318,000 gallons (1.2 million liters) of liquid oxygen needed for combustion. At liftoff, the stage’s five F-1 rocket engines ignite and produce 7.5 million pounds of thrust.
What is the rocket equation used for?
The rocket equation can be applied to orbital maneuvers in order to determine how much propellant is needed to change to a particular new orbit, or to find the new orbit as the result of a particular propellant burn.
What is ISP rocket?
Specific impulse (usually abbreviated Isp) is a measure of how effectively a rocket uses propellant or a jet engine uses fuel. Specific impulse can be calculated in a variety of ways with different units. A propulsion system with a higher specific impulse uses the mass of the propellant more efficiently.
Is a bullet faster than a rocket?
Both could be faster than the other depending on the bullet and gun or rocket. Historically rockets are typically faster. Some of the fastest “bullets” ever fired have been from the naval electromagnetic rail gun. They claim their fully capable gun is able to achieve about 2.4km/s(5,400 MPH), that is really fast!
What is the principle of rocket?
Rocket Principles. A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon.
