A rocket is a projectile that spacecraft, aircraft or other vehicles use to obtain thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space.
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Chinese, Indians, Mongols and Persians, as early as the 13th century.
A model rocket is a small rocket designed to reach low altitudes and be recovered by a variety of means.

Helmut Gröttrup was a German engineer, rocket scientist and inventor of the smart card. During World War II, he worked in the German V-2 rocket program under Wernher von Braun. From 1946 to 1953 he headed a group of 170 German scientists who were forced to work for the Soviet rocketry program under Sergei Korolev. After returning to West Germany in December 1953, he developed data processing systems and contributed to early commercial applications of computer science. In 1967 Gröttrup invented the basic principles of the smart card as a forgery-proof "key" for secure identification and access control.

A monocopter or gyropter is a rotorcraft that uses a single rotating blade. The concept is similar to the whirling helicopter seeds that fall from some trees. The name gyropter is sometimes applied to monocopters in which the entire aircraft rotates about its center of mass as it flies. The name "monocopter" has also been applied to the personal jet pack constructed by Andreas Petzoldt.
