Air transport. A variety of aircraft

Today, the concept of air transport, as a rule, implies a such air assets like helicopters and planes, although in reality the air transport includes a much larger classification, and, if at first glance it may seem that these vehicles are related to each other , in reality it is somewhat different.

Air transport. Classification on the basis of the flight.

As known, the principle of flight of the aircraft based on the lifting force, and in dependence on the type of a particular air transport, the lifting force can be divided into:

  1. Aeronautical, the principle of which is based on overcoming the force of gravity of the aircraft due to the displacement volume of air equal to that force;
  2. Aerodynamic, based on the force interaction of a moving aircraft and the displaced air, as a rule, due to the surfaces swell, causing air traffic to climb up even though he is much heavier than air;

  1. Raketodinamicheskuyu arising on the principle of operation of the action pulse combustion;

Thanks to all of the physical principles, air transport was a significant development, and it is possible that the further development of this science classification list will grow.

Air transport. Classification of aircraft

Today aerostatic machines include air transport such as:

  • Balloons air devices without purposeful movement in the horizontal plane;
  • Airships, air devices that can be controlled in the vertical and in the horizontal plane at the expense of engine used here.

It should be noted immediately that the air transport today is not widely used due to its lack of speed of movement, but still continues to be used for private purposes.

Aerodynamic aircraft we found so far the widest distribution, and used in accordance with the statistics on 95% of the total number of air transport available in the world. For aerodynamic air transport include:

  • Helicopters (helicopters), whose operation is based on the creation of lift due to the rotation of the rotor around the vertical axis;

  • Planes, ekranolёty, WIG, moto hang-gliders, paramotors, whose operation is based on the creation of lift due to airflow passing over the fixed wing of the greatest ways due to the curvature of its shape;
  • Autogyros representing air transport, operating on the principle of the free rotation of the rotor in a vertical plane;

  • Maholёty, creating a lifting force due to the flapping of the wings;
  • Rotary wing, representing the combination screw option of air transport and air transport fixed-wing;
  • Gliders, paragliders, hang gliders and zhestkoplany representing the aircraft is not used in the engine and moving the flight due to the forces of gravity and aerodynamic forces.

Aircraft operating on the principle raketodinamicheskom usually not found its wide application, however, it is likely that this could happen in the near future. To date, this principle is used in launch vehicles, and it is likely that soon the other designers will find good use for it in civil air transport.

It is also worth highlighting one more class of air transport, which has not been used today, the works on the creation of which have been conducted since the times of the USSR - the so-called airplanes with aerostatic discharge. The principle of their work is based on the fact that around 80% of lift force they create cylinders with helium, and after raising to the required height the aircraft is driven in the horizontal plane by ordinary cruise engines.

Thus, air transport is sufficiently broad classification, and it is likely that in the next few years is a list of more significantly expand due to technical and scientific progress.
