COMPARISON BETWEEN GLIDER, HANG GLIDER, PARAGLIDER
Glider aircraft are heavier than aircraft that are supported in flight
By the dynamic reaction of to air against their lifting surfaces, and
Whose free flight does not depend on the engines. Mostly these
types of aircraft are intended for routine operations without engines,
though engine failure can force other type of aircraft to glide. Some
Gliders have engines for extending there flights and some have
Engines powerful enough to launch.
There are wide variety of differing in the construction of their wings,
Aerodynamic efficiency, location of the pilots and controls. Some may
Have power plants to take off and extend flight. Some are designed
Simply to descend, but the most common varieties exploit the
Meteorological phenomena to maintain or even gain heights. Gliders
Are principally used for the air sports of gliding, hang gliding and
Paragliding but are also used for recovering spacecrafts. Perhaps the
Most popular type is paper plane.
Made of wood and metal but the majority now have composite
materials using glass, carbon fibre.
Fly long distances.
Both single-seat and two-
seat gliders are available.
Wheels are used
Mostly fetch with electrical
Wings are made of a fabric wing called RAM-AIR FOIL
A free-flying, foot-launched aircraft.
A glide ratio of 10 at 45 km/h.
Use rising air to gain height.
Paramotors are attached to
some types which are known
as powered paragliders.
Made from common and inexpensive materials such as wood,
though a few were retrieved and re-used.
Used for carrying troops and heavy equipment to a combat zone,
mainly during the Second World War.
A fixed-wing(fibre-reinforced plastic ) aircraft that can be flown
with or without engine power.
A fixed wing, capable of sustained soaring flight without thrust
from the means of propulsion.
Wheels are used for
A light weight slow flying model aircraft designed to be kept
aloft by slope soaring in the lift generated by a paddle
held by the pilot who walks along
with the glider as it flies.
Walkalong gliding has also been
referred to as controllable slope
soaring but should not be confused
with dynamic soaring or ground
effect in aircraft.
Pilots can take off from a slight slope or a steep mountain top
and fly for hours.
It include rising columns of hot air (thermals) found over places
that take in plenty of sunlight, like sand or pavement.
Pilots also look for updrafts of air deflected by ridges (ridge lifts)
to provide additional lift. Upward currents of air between two
mountain ridges, called wave currents, can provide additional lift
An experienced pilot tries to avoid turbulent air, which can slow the glider and cause it to tumble, and such obstacles as power lines and tall structures.
