3A brief introduction
- History Rockets Development
- Scientists believed that the Chinese invented
rockets and was the first to build a working
rocket which was describe as "Arrows of flying
fire" By 1300 the use of rockets has spread
through out much of Asia and Europe. - These first rockets burned a substance called
black powder which consisted of charcoal salt
paper and sulfur which used as a fireworks and as
a weapon.
4Historical account
- During the early 1800"s. Colonel Congreve of the
British army developed rocket that carried
explosive, some of these rockets weighed as much
as 60 pounds . - Several other countries also developed military
rockets. In 1800"s an English inventor William
Hale improved accuracy in Military rockets by
substituted three fins for the long wooden tail
which was used to guide the rocket, these rocket
was used in the Mexican war and the American
Civil war (1861-1865).
5Time line
The success of Indian rocket barrages against the
British in 1792 and again in 1799 caught the
interest of an artillery expert, Colonel William
Congreve.
In 1898, a Russian schoolteacher, Konstantin
Tsiolkovsky (1857-1935), proposed the idea of
space exploration by rocket. I
During the latter part of the 17th century, the
scientific foundations for modern rocketry were
laid by the great English scientist Sir Isaac
Newton (1642-1727).
The Congreve rockets were highly successful in
battle. Used by British ships to pound Fort
McHenry in the War of 1812, they inspired Francis
Scott Key to write "the rockets' red glare,"
words in his poem that later became The Star-
Spangled Banner.
A third great space pioneer, Hermann Oberth
(1894-1989) of Germany, published a book in 1923
about rocket travel into outer space.
During the end of the 18th century and early into
the 19th, rockets experienced a brief revival as
a weapon of war.
Somewhere around the year 400 B.C ., Archytas
mystified and amused the citizens of Tarentum by
flying a pigeon made of wood.
6principles
- By 1300 the use of rockets has spread through out
much of Asia and Europe. - A Russian teacher named Konstantin Tsiolkovsky
read about the use of rockets and space travel,
he became serious and turned his attention to
rocket theory and worked on a rocket design .
7How rockets work
- The rocket climbed 184 ft into air at a speed of
60 miles per hour. - American forces captured V-2 missiles and sent
them to the United States for use in research.
8Scientific Process
- Early 20th century. In many of his theory he
proposed space exploration by rocket, liquid
propellant, space station and he was the first to
present the idea of the multistage rocket. - Hermann O Berth a German Scientist led a small
group of German Engineers and Scientist by
experimenting on rockets by theory and designing
in 1923 he published a work in which he proved
that flight beyond the atmosphere is possible.
9Nature of science
- He also proposed liquid propelled rockets,
multistage rockets, space navigation and re-entry
system . - . From 1939 to 1945 he worked on Germans war
rocket programs with Wemher Braun - The German wanted to build a rocket which would
carry a bomb from Europe to strike New York City.
10Problem solving
- Dr. Robert H. Goddard an American Pioneer of
rockets his design and model eventually led to
the German big rockets such as the V-2 which was
used against the allied in World War II. - After the war some scientist went to the Soviet
Union other came to the USA to continue rocketry
work.
11process
- In 1915 he tested solid fueled models and began
working on perfecting rocket weapons, one of his
design was the fore runner of the bazooka a tube
launched missile, 18 inches long, it was tested
in 1918. - It was never used in the war because the war
ended.
12Practical rocketry
- 1919 Dr Goddard a paper which stated that a
rocket would have worked better in a total vacuum
than in our atmosphere, he also suggest that a
multi-stage rocket that can reach high-altitudes
and even reach the escape velocity of the earth.

16Positive Aspects
- Space flight offered new challenges and problems
very different from aviation .
