Thermodynamic cycle

A thermodynamic cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventually returns the system to its initial state.

V-1 flying bomb

The V-1 flying bomb (Vergeltungswaffe 1 "Vengeance Weapon 1")—also known to the Allies as the buzz bomb, or doodlebug, and in Germany as Kirschkern (cherrystone) or Maikäfer (maybug)—was an early cruise missile and the only production aircraft to use a pulsejet for power.

Water injection (engine)

In internal combustion engines, water injection, also known as anti-detonant injection (ADI), can spray water into the incoming air or fuel-air mixture, or directly into the cylinder to cool certain parts of the induction system where "hot points" could produce premature ignition.

World War II

World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although conflicts reflecting the ideological clash between what would become the Allied and Axis blocs began earlier.

Zero-length launch

The zero-length launch system or zero-length take-off system (ZLL, ZLTO, ZEL, ZELL) was a system whereby jet fighters and attack aircraft were intended to be placed on short-burn duration, often solid-fuel, "dropaway" rocket booster units, deployed with mobile launch platforms.
