aeronautics

From The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide
Science of travel through the Earth's atmosphere, including aerodynamics, aircraft structures, jet and rocket propulsion, and aerial navigation. It is distinguished from astronautics , which is the science of travel through space. In subsonic aeronautics (below the speed of sound), aerodynamic forces increase at the rate of the square of the speed. Trans-sonic aeronautics covers the speed range from just below to just above the speed of sound and is crucial to aircraft design. Ordinary sound waves move at about 1,225 kph/760 mph at sea level, and air in front of an aircraft moving slower than this is ‘warned’ by the waves so that it can move aside. However, as the flying speed approaches that of the sound waves, the warning is too late for the air to escape, and the aircraft pushes the air aside, creating shock waves, which absorb much power and create design problems. On the ground the shock waves give rise to a sonic boom . It was once thought that the speed of sound was a speed…

Full text Article AVIATION and AERONAUTICS

From The Welsh Academy Encyclopaedia of Wales
Although balloonists such as James Sadler ventured into Welsh skies in the 19th century, it was not until the Edwardian era that aviation proper began to develop. Pioneering aircraft constructors, such as the Pembrokeshire -born James brothers, Horace Watkins and W. E. Williams , were followed by…
