Transcript of FLIGHT

Some things generate little or no lift and move only or mostly under the action of momentum, gravity, air drag and in some cases thrust. This is termed ballistic flight.
Examples include balls, arrows, bullets, fireworks etc.
-Flight is the process by which an object moves, through an atmosphere

- by generating aerodynamic lift, propulsive thrust, aerostatically using buoyancy, or by ballistic movement, without direct support from any surface.
-The kite may have been the first form of man-made aircraft.
-It was invented by Mo Di and Lu Ban
-Man-carrying kites are believed to have been used in ancient China, for both civil and military purposes
The Kite
-Mechanical flight is the use of a machine to fly.

- aircraft such as airplanes, gliders, helicopters, autogyros, airships, balloons, ornithopters and spacecraft
- Gliders are capable of unpowered flight.

- Para-sailing is where a parachute-like object is pulled by a boat.

- In an airplane, lift is created by the wings; the wings are designed specially for the type of flight desired.

- There are different types of wings: tempered, semi-tempered, sweptback, rectangular and elliptical.

- An aircraft wing is sometimes called an airfoil, which is a device that creates lift when air flows across it.
Mechanical Flight
-Supersonic flight is flight faster than the speed of sound. -Supersonic flight is associated with the formation of shock waves that form a sonic boom that can be heard from the ground.
-This shockwave takes quite a lot of energy to create
Supersonic Flight
-Hypersonic flight is very high speed flight where the heat generated by the compression of the air due to the motion through the air causes chemical changes to the air
- Hypersonic flight is achieved by reentering spacecraft such as the Space Shuttle and Soyuz.
Ballistic Flight
Atmospheric Flight
-spaceflight is the use of space technology to achieve the flight of spacecraft into and through outer space.
-Examples include ballistic missiles, orbital spaceflight etc.
is used in space exploration, and also in commercial activities like space tourism and satellite telecommunications.
Hypersonic Flight
Leonardo Da Vinci's Ornithopter

-He invented not only the Ornithopter but he also invented parachutes
- Da Vinci researched birds and how they fly. He then came up with the Ornithopter, which was a wing propelled flying machine, where the flyer would sit horizontally and pedal, making the wings flap.
-Montgolfier brothers invented the very first ever hot air balloon in France. The brothers
- first passengers in the colorful balloon were a sheep, rooster, and a duck. The balloon climbed to a height of 6000 feet and traveled more than one mile.
- brothers used the smoke from a fire to blow hot air into a large silk bag so the balloon will travel upwards.
-For balloon to travel down ,they would put out the fire therefore letting cooler air into the balloon.
The Glider
- was considered the father of aerial navigation because of his invention of the glider
-His glider was the first to carry a man successfully across Brompton Dale in England by Cayleys coachman.
-Cayley drew his machine with a fixed wing, fuselage, and a tail on a silver disc.
Orville and Wilbur Wright first looked at earlier flight developments (look back) then after the research they tested their early theories with balloons and kites. Then they tested the shapes of gliders, much like George Cayley did, and spent time learning how to control gliders.
The first flyer was called the Kitty Hawk Flyer
Wright Brothers Flight (1903)
5th Century
World War II
-World War II saw a great increase in the pace of development and production, not only of aircraft but also the associated flight-based weapon delivery systems.
- Large scale strategic bombing campaigns were launched, fighter escorts introduced and the more flexible aircraft and weapons allowed precise attacks on small targets with dive bombers, fighter-bombers, and ground-attack aircraft.
-The first jet aircraft to fly was invented, as well as the world's first jet-powered bomber, and the first cruise missile (V1) and the first ballistic missile (V2).
-Helicopter's also developed during this era.

Human beings have been obsessed by the idea of flight since the dawn of recorded history. Men have always imagined themselves among the clouds, wheeling and soaring like birds. It seems to give them a sense of freedom, away from mortal constraints.
Man's Desire to Fly
Flight Today
Nowaday's flight occurs mainly for commercial purposes. Also at the beginning of the 21st century, subsonic military aviation focused on eliminating the pilot in favor of remotely operated or completely autonomous vehicles. Several unmanned aerial vehicles or UAVs have been developed
Yves Rossy developed and built a system comprising a back pack with semi-rigid aeroplane-type carbon-fiber wings with a span of about 2.4 metres (7.9 ft), powered by four attached Jet-Cat P200 jet engines[3] modified from large kerosene-fueled model aircraft engines. Later in 2008, he made a flight over the Alps, reaching a top descent speed of 304 km/h (189 mph) and an average speed of 124 mph.
The Martin Jetpack is an experimental aircraft.It uses a gasoline (premium) engine with two ducted fans to provide lift. Its design claims a 60 mile per hour maximum speed, an 8,000 foot flight ceiling, with a flight time about 30 minutes on a full fuel tank.

Mind-Controlled Helicopter
The Puzzlebox Orbit is operated via a NeuroSky EEG headset plus either a mobile device or the dedicated Puzzlebox Pyramid remote. Users can fly the Orbit through focused concentration or by maintaining a state of mental relaxation
