Who is robert a braeunig? My name is Robert A. Braeunig and I am the creator of Rocket and Space Technology. After viewing my webpage you may come to the conclusion that I may be some sort of 'rocket scientist' or perhaps a model rocketry enthusiast. Both of these assumption would be incorrect. My education is in the field of civil engineering and I currently work for a construction company in Dayton, Ohio.
What is rocket technology?
Rocket launch technologies include the entire set of systems needed to successfully launch a vehicle, not just the vehicle itself, but also the firing control systems, mission control center, launch pad, ground stations, and tracking stations needed for a successful launch or recovery or both.
Why would some rockets benefit from a reduction in thrust over time?
This lower mass means that the rocket starts to accelerate more quickly. Thrust is carefully reduced during launches for rockets carrying astronauts to protect them from this increasing acceleration.
What happens in a rocket engine?
In a rocket engine , fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust. There are two main categories of rocket engines; liquid rockets and solid rockets.
How are rockets useful?
Rockets are used to launch satellites and Space Shuttles into space. Their powerful engines allow spacecraft to be blasted into space at incredible speeds, putting them into the correct orbit. Europe's most important rocket family is the Ariane.

Does a rocket carry humans?
NASA uses rockets and spacecraft to send humans into space. Some spacecraft go where humans cannot travel.
How are rockets created?
The Chinese began experimenting with the gunpowder-filled tubes. At some point, they attached bamboo tubes to arrows and launched them with bows. Soon they discovered that these gunpowder tubes could launch themselves just by the power produced from the escaping gas. The true rocket was born.
Can a rocket go faster than its exhaust speed?
It is possible for the velocity of a rocket to be greater than the exhaust velocity of the gases it ejects. Yes, the rocket speed can exceed the exhaust speed of the gases it ejects. The thrust of the rocket does not depend on the relative speeds of the gases and rocket, it simply depends on conservation of momentum.
What is the most efficient rocket engine?
ARCA Space Corporation has announced that it will launch its aerospike rocket engine – a type of engine that can boost a rocket from the ground into space in only one stage – in August this year.
Are rocket cars real?
A rocket car is a land vehicle propelled by a rocket engine. A rocket dragster is a rocket car used for competing in drag racing, and this type holds the unofficial world record for the 1/4 mile.
How does rocket fuel work?
Rocket fuel works on the basis of Newton's Third Law of Motion, which states that 'every action is accompanied by an equal and opposite reaction'. By ﬁring fuel out the back of a rocket, the force propels it upwards with acceleration equal to the force at which the fuel is expelled.
What is C * efficiency?
The C-efficiency ratio is the most commonly used indicator for evaluating the revenue. performance and overall efficiency of the VAT system. It is simply the ratio of actual revenues to. theoretical revenues from a perfectly enforced tax levied at a uniform rate on all consumption. It.
Who invented the rocket?
American rocketry pioneer Robert H. Goddard and his first liquid-fueled rocket, March 16, 1926. Dr. Robert Hutchings Goddard (1882-1945) is considered the father of modern rocket propulsion.
How have rockets changed the world?
Scientists use telescopes in space because the Earth's atmosphere distorts some of our light and view. It takes a giant rocket over a 100 feet high to put a satellite or telescope in space. Rockets carry astronauts into space. Rockets have changed the world completely and have given us new eyes for the universe.
How do rockets land on Earth?
Currently, SpaceX rockets use 4 landing legs that are folded against the rocket's body during flight. These then fold out using gravity prior to landing. But, Elon Musk stated in January 2021 that for SpaceX's largest rocket ever, the Super Heavy booster, they would aim to “catch” the rocket using the launch tower arm.
How far has human gone in space?
The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970.
Are there any humans currently in space?
Currently, 14 astronauts aboard three different spacecraft are in space. They are NASA astronauts Shane Kimbrough, Megan McArthur and Mark Vande Hei; Japan's Akihiko Hoshide; Russian cosmonauts Pyotr Dubrov and Oleg Novitskiy, and European Space Agency's Thomas Pesquet, according to NASA records.
Which countries sent astronauts to space?
Only three nations (Soviet Union/Russia, U.S., China) have launched their own crewed spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts. Twenty-seven "first flights" occurred on Soviet or Russian flights while the United States carried fourteen.
Who created NASA?
While this new federal agency would conduct all non-military space activity, the Advanced Research Projects Agency (ARPA) was created in February 1958 to develop space technology for military application. On July 29, 1958, Eisenhower signed the National Aeronautics and Space Act, establishing NASA.
What was the first rocket?
The first rocket which could fly high enough to get into space was the V2 missile which was first launched by Germany in 1942. The first rocket which actually launched something into space was used to launch Sputnik, the first satellite, on October 4, 1957.
Why does NASA use hydrogen?
NASA's hydrogen and fuel cell technologies are used for many purposes. NASA has relied upon hydrogen gas as rocket fuel to deliver crew and cargo to space. With the recent focus on human missions to the moon and eventually Mars, hydrogen will continue to be innovatively stored, measured, processed and employed.
Why do rockets keep accelerating?
Newton's Second Law
Let's apply this principle to a rocket. The pressure created by the controlled explosion taking place inside the rocket's engines is a force called thrust. That pressure accelerates the gas one way and the rocket the other. The thrust for the rocket continues as long as its engines are firing.
Is a spacecraft faster than a bullet?
The rocket is almost 6 times faster. When fired, the rifle bullet travels toward the target, but gravity immediately begins pulling it downward.
Is there momentum in space?
Momentum is defined as the mass of an object times its velocity. In a similar manner, a rocket moves in space because the gases are given momentum as they are expelled by the rocket engine. Consider the rocket resting in space. There is no momentum in the system.
How big is a Raptor engine?
The 2020 Ford Raptor features a twin-turbocharged high-output 3.5L EcoBoost V6 engine that dishes out 450 horsepower and 510 lb-ft of torque.

Which car can go 1000 mph?
For sale: a rocket-powered car named Bloodhound built specifically to break the land speed record. Theoretical top speed of 1,000 miles per hour. Seats one. Price?
Has any car hit 400 mph?
As he was walking to a math class during his freshman year at Ohio State University, R. J. Kromer spotted a poster for a student-run team designing a fuel-cell-powered car.
What is the slowest car in history?
The slowest production car in existence is a coupe manufactured by Peel Engineering. It is called the Peel P50. Peel offers both a petrol and electric version of the vehicle. Not only is it the slowest car in existence, but it is also the smallest (smaller than a Smart Car or Fiat), according to Guinness World Records.
Why do rockets carry their own oxygen?
Since there is no air and space, rockets need to take oxygen with them into space. That gas has pressure, and it pushes harder against the top of the rocket than the bottom, making it go up or forward. Since the fuel is burning, exhaust is released out the bottom.
Why do rockets use kerosene?
The reason they used RP-1 in the first stage is that it's perfect for low altitude rocket flight. The reason RP-1 works so well low down is how much energy you get from each gallon of it. For each gallon of RP-1 you burn you get over 4 times the energy you get from burning a gallon of liquid hydrogen.
