Flintlock, a firing mechanism used on early firearms. It was first used on muskets about 1650, later on pistols. The cock, or hammer, of the flintlock held a piece of flint which, when the trigger was pulled, struck a piece of steel and caused sparks to fly. The sparks ignited a small priming charge of powder in a pan, which was uncovered as the flint struck the steel. The fire flashed through a touchhole, exploding the main powder charge and discharging the ball (bullet). By about 1850 flintlocks had been replaced by percussion locks.
The Nieuport 17 incorporated the best features of monoplanes and biplanes in what was termed the sesquiplane setup. It featured a large top wing and a smaller lower wing joined by a V-shaped strut. Learn the advantages of this classic hybrid design.
Amphibious Warfare, military campaigns of combined land and sea forces. Since no military action of any size would be undertaken without also using air power, the word triphibious, meaning use of land, sea, and air forces, has been suggested, but it is not commonly used.
