Rocket SCience !

 ராக்கெட் எப்படி பறக்கும் !!  ப்ரஹ்மானந்தம் கேள்வி ?


You might have heard the phrase “It is not rocket science” tossed around!. When someone says “It’s not rocket science,” what they really mean is that something is not so difficult. Rocket scientists are brilliant people, but rocket science is based on concepts that we understand.


Rocket propulsion is defined as ‘the  force that is used by the rocket to take off from the ground and into the atmosphere’.


Thrust is the force which moves any aircraft through the air. Thrust is generated by the propulsion system of the aircraft. Different propulsion systems develop thrust in different ways, but all thrust is generated through some application of Newton's third law of motion. For every action there is an equal and opposite reaction. In any propulsion system, a working fluid is accelerated by the system and the reaction to this acceleration produces a force on the system. A general derivation of the thrust equation shows that the amount of thrust generated depends on the mass flow through the engine and the exit velocity of the gas.


During and following World War II, there were a number of rocket- powered aircraft built to explore high speed flight.


One need not know rocket Science, just see and enjoy life with little things that gives us happiness.  Happy morning
