who invented the glider

George Cayley
In 1853, British engineer George Cayley built the world’s first real glider. It carried his terrified servant on a short flight across a small valley before crash-landing. Later, in the 1890s, Otto Lilienthal of Germany built a series of small, fragile gliders.

Otto Lilienthal
Hang gliders were developed by the pioneers of practical flight. In Germany, starting in 1891, Otto Lilienthal made several thousand flights before a fatal gliding accident in 1896. He published plans of his gliders and even supplied kits.

 who invented the underwater glider

This idea, a glider with a buoyancy engine powered by a heat exchanger, was introduced to the oceanographic community by Henry Stommel in a 1989 article in Oceanography, when he proposed a glider concept called Slocum, developed with research engineer Doug Webb.

do you wear a parachute while hang gliding

Pilots carry a parachute enclosed in the harness. In case of serious problems, the parachute is manually deployed (either by hand or with a ballistic assist) and carries both pilot and glider down to earth. … The accident rate from hang glider flying has been dramatically decreased by pilot training.

Sir George Cayley

Sir George Cayley, also called Sir George Cayley, 6th Baronet, (born December 27, 1773, Scarborough, Yorkshire, England—died December 8, 1854, Brompton, Yorkshire), English pioneer of aerial navigation and aeronautical engineering and designer of the first successful glider to carry a human being aloft.

Fascinated by flight since childhood, Cayley conducted a variety of tests and experiments intended to explore aerodynamic principles and to gather information of value in the design of aircraft.

helicopters

He published the results of his original research in 1809. His most important discoveries included the advantages of streamlining, the means of obtaining longitudinal and lateral stability, elements of wing design, thoughts on biplane and multiplane wings, and the use of rudders and elevators for control. Throughout his active career, Cayley designed a variety of aircraft, including helicopters, airships, and fixed-wing machines.

Cayley established the modern configuration of an airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control as early as 1799 (see Silver Disc machine). In 1804 he flew the first successful glider model of which there is any record. His work culminated in 1853 with the completion of a full-scale glider that carried his reluctant coachman on the first manned glider flight on record.

An individual of wide technical

An individual of wide technical and scientific interests, Cayley invented the light-tension wheel (forerunner of the bicycle wheel), the expansion-air, or hot-air, engine (1805), and the caterpillar tractor (1825). He was a founder of the Regent Street Polytechnic Institution (charter of incorporation granted in 1839; now the Royal Polytechnic Institution). He also pursued research in science education, land reclamation, acoustics, railway equipment, lifeboats, ballistics, optics, and electricity.

Glider

Glider, nonpowered heavier-than-air craft capable of sustained flight. Though many men contributed to the development of the glider, the most famous pioneer was Otto Lilienthal (1848–96) of Germany, who, with his brother Gustav, began experiments in 1867 on the buoyancy and resistance of air. Lilienthal also investigated camber and wing sections and studied ways to increase the stability of the gliders he built, finally incorporating stabilizing tail surfaces. In 1891 he built his first man-carrying craft, with which he could take off by running downhill into the wind.

Octave Chanute

Octave Chanute, French-born American engineer, began designing gliders that were flown by others under his supervision. He discarded Lilienthal’s method of securing control by a fixed rear fin with the horizontal tail parts freely hinging upward, and instead substituted a rudder and articulated (segmented) wings. Chanute’s gliders were so stable that they made 2,000 flights without an accident.

Orville and Wilbur Wright built their most successful early glider in 1902. Following experimentation they decided to use a vertical rudder that was movable in flight. They then added a horizontal elevator and combined their adjustable vertical rudder with a wing-warping mechanism that permitted them to move the trailing edges of the wings up and down. This perfect control made their gliding safe and allowed them to proceed to the powered airplane.

favoured launching techniques

To fly, a glider must be accelerated to flying speed, the speed at which wings generate enough lift to overcome the force of gravity. In most of the early gliders, flying speed was very low; normal practice was to fly into a wind so that the actual acceleration required was not great. Today’s favoured launching techniques are the airplane tow and the automobile tow. While hang gliders usually are launched from a high point and descend, sailplane gliders can soar for hours on the lift from thermals and rising air due to rising terrain.

gliders equipped

Since 1935, gliders equipped with recording instruments have gained in reputation as tools for aeronautical and meteorological research. Gliders were widely used in World War II to carry troops and goods. They, and sailplanes in particular, have become increasingly popular for recreational purposes and as vehicles for sports competition.
