The types of aircraft
Aircraft based on the classification standard of different, can have the following methods:
1. According to the use of aircraft division, civil aviation and national air planes. National aviation aircraft is refers to the military, police and customs such as the use of aircraft, civil aviation aircraft mainly refers to the civil aircraft and helicopters, civilian aircraft refers to civilian aircraft, cargo and passenger and cargo dual-use machine.
2. According to the type of aircraft engine, propeller aircraft and jet. History of propeller aircraft, including piston propeller-powered planes and turboprop aircraft, aircraft engines is the piston screw type, this is the most primitive form of motivation. It using the rotation of the propeller to the air to the machine, after the reaction moves aircraft by them. Propeller speed the higher, the faster the speed. Jet aircraft, including jet vortex theory and vortex theory of jet fan. This model has the advantage of simple structure, fast speed, generally can reach 500-500 miles per hour. Fuel cost savings, loading capacity is big, can accommodate 400-400 or 100 tons of cargo.
3 points by the number of aircraft engine, a single machine (motivation), double (motivation) planes, three hair (motivation) aircraft, four hair (motivation) aircraft.
4. According to the flight speed of points, has the branch of subsonic and supersonic aircraft, subsonic aircraft, aircraft at low speed (the speed under 400 km/h) and high subsonic aircraft (flying speed of Mach number is 0.8 to 0.8). Most of the jet for high subsonic aircraft.
5. According to the aircraft flight near and far points, with short-range, medium-range, long-range aircraft. Remote distance is about 1100 kilometers, can be done without landing intercontinental flight across the sample. About 3000 kilometers, medium-range aircraft flight for short-range aircraft flight generally less than 1000 kilometers. Short-range aircraft are used for feeder, so also called regional aircraft. Medium and long-range aircraft are used for main domestic and international routes, also known as main plane.
China's civil aviation administration of China is divided by number of passenger travelling by large, medium and small aircraft, the aircraft on the number of guest sit under 100 for small, as the medium between 100-100, 200 or more for large. For short distance under 2400 km.
