Rocket Missile Aircraft Vehicle Thrust Rocket Engine Propellants Action and Reaction

The document summarizes the early designs of hot air balloons by the Montgolfier brothers and Charles. While the Montgolfier designs had issues like sparks from the fire igniting the paper balloons, necessitating buckets of water to douse fires, Charles' design was more modern. Both balloon types became known as the Montgolfière for hot air and Charlière for hydrogen balloons. The document also provides brief background on rockets, noting they obtain thrust by expelling propellants from the rear and have been used for military purposes since 13th century China, with significant applications emerging in the 20th century space age.

The Montgolfier designs had several shortcomings, not least the need for dry weather and a

tendency for sparks from the fire to set light to the paper balloon. The manned design had a gallery
around the base of the balloon rather than the hanging basket of the first, unmanned design, which
brought the paper closer to the fire. On their free flight, De Rozier and d'Arlandes took buckets of
water and sponges to douse these fires as they arose. On the other hand, the manned design of
Charles was essentially modern.[10] As a result of these exploits, the hot-air balloon became known
as the Montgolfière type and the hydrogen balloon the Charlière.

A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust from
a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the
rocket before use.[16] Rocket engines work by action and reaction. Rocket engines push rockets
forwards simply by throwing their exhaust backwards extremely fast.
Rockets for military and recreational uses date back to at least 13th-century China.[17] Significant
scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was
the enabling technology of the Space Age, including setting foot on the moon.
