Abstract

The article focuses on gliders, engineless aircraft that use natural air currents—thermal, ridge, and wave lift—to stay aloft without propulsion. Gliders require external assistance for takeoff, typically via winch launch or aerotow, and pilots control descent using air brakes and precise maneuvers. The design of gliders includes streamlined components such as wings, fuselage, and stabilizers to optimize lift and reduce drag. The first manned fixed-wing glider was invented in 1853 by British engineer George Cayley, whose design principles influenced later powered aircraft. Gliders are primarily used for recreation, sport, training, and atmospheric research, offering an environmentally friendly alternative to engine-powered planes. [Extracted from the article]
