The Concept of Flight and Classification of Aircraft

 

  In 1783, the first manned hot air balloon, ten days later first gas balloon  with lift Speed and Direction.

1903 First Human Flight and 1933 Steam engine in an aircraft. 

 In 1903 December 17th, the Wright brothers had flown a total of 98 seconds on four flights andThe age of flight had arrived. The Wright brothers traveled 852 feet

Passenger air travel inFlorida and 1914 they traveled between St. Petersburg and Tampa.

          

       International civil aviation organisation 

 The International Civil Aviation Organization is a specialized agency of the United Nations that coordinates the principles and techniques of international air navigation, and fosters the planning and development of international air transport to ensure safe and orderly growth and founded on 17th December 1947.

  ICAO is funded and directed by 193 national 

governments to support their diplomacy and 

cooperation in air transport as signatory states to 

the Chicago Convention (1944).

        

              The Four Forces of Flight

  These same four forces help an airplane fly. The four forces are lift, Trust, weight and Drag.

An airplane in flight is acted on by four forces lift, the upward acting force, gravity the downward acting force, thrust the forward acting force and drag the backward acting force (also called wind resistance).

Lift opposes gravity and thrust opposes drag .Drag and gravity are forces that act on anything lifted from the earth and moved through the air. Thrust and lift are artificially created forces used to overcome the forces of nature and enable an airplane to fly.

Airplane engine and propeller combination is designed to produce thrust to overcome drag. Their wings are designed to produce lift to overcome gravity.

                  Classification of Aircraft

Ultralight vehicle

- Powered ultralight vehicles must weigh less than 254 pounds empty weight and Unpowered ultralight vehicles must weigh less than 155 pounds. Rules for ultralight vehicles are significantly different from rules for aircraft.

Airplane 

an engine driven, fixed wing aircraft and heavier than air that is supported in flight by the dynamic reaction of the air against its wings.

Glider

Lighter-than-air aircraft- an aircraft that can rise and remain suspended by using contained gas weighing less than the air that is displaced by the gas. Airship and Balloon.

Powered lift is a heavier-than-air aircraft.  

Powered parachute 

Rocket

Rotorcraft

Weight shift control

 Types of Aircraft are so many different it depends on the generations.
