Design
The Fire Arrow was the first rocket in mechanism and design. It was made in a variety of forms and launched in diverse manners, but the first design consisted of a pouch of black powder with a stick attached; the arrows were launched from a stand of bamboo sticks. Like the fins on a modern rocket, the long stick on a fire arrow increases stability and therefore accuracy. (It works by causing the center of drag to be far behind the center of mass, so that atmospheric drag keeps the arrow oriented toward its direction of travel.)
Chinese and Korean fire arrows were usually launched in salvoes from launch platforms such as arrays of cylinders or boxes which could hold as many as 1,000 fire arrows each. The fire arrows propelled by gunpowder may have had a range of up to 1,000 feet.
Fire arrows were tipped with flammable materials like pitch, bitumen or resin.

Famous quotes containing the word design:
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“You can make as good a design out of an American turkey as a Japanese out of his native stork.”
—For the State of Illinois, U.S. public relief program (1935-1943)
