ROCKETRY

A longer journey than you might expect!

Rocketry

• From 400 BC to October 4th, 1957. The historical developmental benchmarks of rocketry.

• Understanding the parts of a basic rocket.

• Production of a successful rocket.

Notes - 400 BC

• 400 BC. – AULUS GELLIUS: He wrote about a man named ARCHYTAS who live in the city of Tarentum, Greece around the year 400 BC.

CONTINUED……

• ARCHYTAS would mystify and amuse the children and citizens by flying a PIGEON made of wood. It appears that the bird was suspended by wires and propelled along by escaping steam.

CONTINUED…..

• The PIGEON used the ACTION-REACTION PRINCIPLE that was not to be stated as a scientific law until the 17th century.

Notes – 100 BC

• HERO OF ALEXANDRIA (Greece) invented a similar ROCKET LIKE DEVICE called an AEOLIPILE.

Notes – 1st Century AD

• The CHINESE had a simple form of GUNPOWDER. They would put this mixture into BAMBOO TUBES and toss these tubes into the fires during religious festivals.

CONTINUED…..

• They then began attaching these tubes to arrows. It was discovered that this combination could launch itself just from the power produced from the ESCAPING GASSES.

• THE TRUE ROCKET WAS BORN.

Continued…..

• The first date known that these rockets were used was the year 1232. Used in the battle of KAI-KENG. The Chinese repelled the MONGOL invaders by a barrage of “arrows of flying fire”.

Continued…..

• Following this battle the Mongols produced rockets of their own and may have been responsible for the spread of rockets to Europe.

Additional Info…..• Many records describe rocket experiments

through out the 13th to the 15th centuries. In England, a monk named Roger Bacon worked on improved forms of gunpowder that greatly increased the range of rockets. In France, Jean Froissart achieved more accurate flights by launching rockets through tubes. Froissart’s idea was the forerunner of the modern bazooka. Joanes de Fontana of Italy designed a surface-running rocket-powered torpedo for setting enemy ships on fire.

NOTES - 17th CENTURYRocketry becomes science- Latter part of the 17th century the foundations were laid for modern rocketry by Sir Isaac Newton. Newton organized his understanding of physical motion into three specific laws.

For a more thorough understand of Sir Isaac Newton go the following URL:

http://www.newton.ac.uk/newtlife.html

CONTINUED…..

•Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an outside force.

CONTINUED…..

•Force is equal to mass X acceleration. (F=MA)

CONTINUED…..

•For every action there is always an opposite and equal reaction.

CONTINUED…..

• These are the three laws of motion, which always existed, were first put into words to be studied and understood by Sir Isaac Newton.

NOTES – MODERN ROCKETRY BEGINS

• 1898 – Russian school teacher, Konstantin Tsiolkovsky, proposed the exploration of space by rocket, proposed liquid fuels for greater range. For his ideas, careful research, and great vision, Tsiolkovsky has been called “the father of modern astronautics.”

CONTINUED…..• Early in the 20th century, American Robert

Goddard conducted practical experiments with rockets. Goddard reached several conclusions important to rocketry.• rockets operate with greater efficiency in a

vacuum than in air• multistage or step rockets were the answer to

achieving high altitudes and the velocity to escape the earth’s gravity.

OCTOBER 4TH, 1957

• Sputnik was launched by the Soviet Union.

• This moment in time changed the world and set it on the course we pursue today.
