Rocket Technology & Science

The Source of aerospace engineering Could be Tracked back into the aviation

Leaders round the late 19th to early 20th centuries, though the

Work of Sir George Cayley dates in the last decade of the 18th to

mid-19th century.  Among the most important people in the history of

aeronautics  and also a pioneer in aeronautical technology, Cayley is

Called the first individual to separate the forces of drag and lift,

Which impact any atmospheric flight automobile.

Early knowledge of aeronautical technology was mostly empirical,

With a few concepts and techniques imported from different branches of

Engineering.  Some Important components, such as fluid dynamics, were

Recognized by 18th-century scientists.

 The 1910s watched the development of aeronautical technology through the

Layout of World War I aircraft.

Between World Wars I and II, Fantastic jumps were made in the Area, hastened by the Arrival of 

mainstream civil aviation.  

Aerospace technology came with the very first operational Jet engine-powered plane, the 

Messerschmitt  Me 262 Which entered service in 1944 towards the conclusion of the next World War.

The very first definition of aerospace engineering appeared in February 1958,[4] considering that the Earth's atmosphere

And outer space as one kingdom, therefore encompassing both aircraft (aero) and spacecraft (space) beneath the

Recently coined term aerospace.

In reaction to the USSR launch the first satellite, Sputnik, into space on October 4, 1957, U.S. aerospace

Administration was founded in 1958 as an answer to the Cold War.  

Assignment to the moon happened.  It watched three astronauts enter orbit around the Moon, with 2, Neil Armstrong

And Buzz Aldrin, seeing the lunar surface.  The next astronaut, Michael Collins, remained in orbit to rendezvous

Using Armstrong and Aldrin following their trip.

London.   due to its capability to maintain up to 480 Passengers.

Another Substantial advancement in aerospace technology came in

1976, together with the development of the very first passenger supersonic

 The development of the aircraft was agreed

Upon by the British and French on November 29, 1962.

Started its initial flight.  It holds the documents for the planet's 

Heaviest aircraft, heaviest airlifted freight, and premier airlifted cargo,

And has the broadest wingspan of almost any aircraft in operational support.

The term rocket science is often used to describe a concept that is quite

difficult to understand but in this video we are going to explain

The technology behind rockets and rocket engines in a simplified scientific manner

to keep the rocket moving you have to eject from at a huge amount of mass at high speed

this is simply Newton's third law of motion the greater the momentum of the rocket loses

the more force or thrust on the rocket to eject the high-speed mass form the rocket

a liquid fuel oxidizer mixture is burnt in the rocket combustion chamber

the combustion chamber also helps fuel and oxidizer to mix in an

efficient manner due to its clever mixing design

the high-speed jet is passed through a special a rocket nozzle

the function of the nozzle is to increase the exhaust velocity even further

thus increasing the Rockets thrust these kinds of nozzles are called converging diverging nozzles

the subsonic flow is converted to a supersonic flow with the help of such a nozzle

the liquid fuel before entering the combine chamber travels entirely around the nozzle body

this helps to reduce the nozzles cover temperature and also results in some energy savings.

to pump the fuel and oxidizer at an adequate flow rate two pumps are used

these pumps are driven by a turbine which is connected to the same shaft as the pumps

the pump turbine unit is referred to as a turbo pump

A gas generator produces hot gas which will turn the turbine.

A bypass stream of fuel and an oxidizer

are fed into the gas generator for the purpose of combustion

exhaust from the turbine is mixed with the main rocket exhaust

this unit of the rocket is called the rocket engine the rocket engine we have discussed

so far is more specifically called a liquid propellant rocket engine they are the most powerful

and versatile rocket propulsion systems available.

The fuel and oxidizer required for the rocket engines are started to large tanks as shown

during liftoff the thrust produced by the main engine may not be sufficient

so usually a few solid propellant strap boosters are used to assist the lift off

you can see more details about solid propellant Rockets here

the rocket starts with zero speed at the ground but it should accelerate to a final speed of around

28000 kilometers per hour to successfully achieve orbit

the solid propellant strap boosters burned off are very rapidly

so to reduce the way of the rocket they are abandoned after the burn-off

this process known as rocket staging when the main engine is burned off

is also abandoned and the next engine takes over the charge

in this way the Rockets weight is greatly reduced thus greater acceleration can be achieved

finally after a few stages of operation the payload is put into the desired orbit

rocket staging up to 5 has been successfully tested.

you might be wondering how the rocket is able to maneuver itself to reach its destination

the most modern car technique is called cabled thrust

here the rocket nozzle is tilted by high precision devices.

it is clear that any deviation from its normal angle

will produce torque which will make the Rockets body turn

after achieving enough to turn the gimbal angle is set to 0.
