2、r （4）airplane,9,10,10,11,2. An airplane can be divided into the following groups according to the types of aircrafts engine. （1）propeller-driven aircraft piston propeller-driven aircraft turboprop propeller-driven aircraft （2）jet aircraft turbojet aircraft turbofan jet aircraft,11,12,3. An airplane

3、can be divided into the following groups according to the aircrafts flight velocity. （1）supersonic aircraft Supersonic aircraft travels faster than the speed of sound. （2）hypersonic aircraft Hypersonic aircraft travels much faster than the speed of sound. （3）transonic aircraft Transonic aircraft tra

4、vels approximately equal to the speed of sound. （4）subsonic aircraft Subsonic aircraft travels slower than the speed of sound but also very fast.,12,13,4. An airplane can be divided into the following groups according to the aircrafts air range. （1）short-range aircraft / short-haul aircraft The air

5、range is shorter than 2400 kilometers. （2）medium-haul aircraft The air range is longer than 2400 kilometers but shorter than 4800 kilometers. （3）long-range aircraft / long-haul aircraft The air range is longer than 4800 kilometers.,13,14,5.

6、ing to the type of landing gear. （1）landplane A landplane is an airplane that can take off from or land on land. （2）seaplane / hydroplane A seaplane or hydroplane is a type of airplane that can take off from or land on water. （3）amphibian An amphibian is an airplane which can land on both land and w

7、ater.,14,15,6. An airplane can be divided into the following groups according to the number of wings. （1）monoplane A monoplane is an airplane with a single pair of wings. （2） biplane A biplane is an old-fashioned type of airplane with two pairs of wings, one above the other. （3）multiplane A multipla

An airplane can be divided into the following groups according to the positions of the wing relative to the fuselage. （1）low wing airplane A low wing airplane is an airplane whose wing is below the cabin. （

9、2） mid wing airplane A mid wing airplane is an airplane whose wing is anywhere between the fuselage. （3）high wing airplane A high wing airplane is an airplane whose wing is above the cabin.,17,18,8. An airplane can be divided into the following groups according to its mission. （1）military aircraft （

10、2）civil aircraft,18,19,Unit 2 Aircrafts Structure,19,20,1. Airframe （1）fuselage The fuselage of the airplane holds all of the parts together and carries the passengers or cargo.,20,21,（2）wing / airfoil The wings generate most of the lift necessary for flight. aileron Ailerons are parts of the wing w

11、hich are used to roll the aircraft. At the trailing edge, its an aileron. leading edge slat trailing edge flap Flaps and slats are parts of the wing which are used during take off and landing to increase lift and drag. spoiler Spoilers are parts of the wing which are used to roll the aircraft and to

12、 decrease lift and increase drag during landings. Between the leading and trailing edges, its a spoiler.,21,22,（3）empennage / the tail assembly vertical stabilizer rudder A rudder is a control surface connected to the vertical stabilizer and is used to yaw the aircraft. horizontal stabilizer elevator Elevators are control surfaces connected to the horizontal stabilizer and are used to pitch the aircraft. stabilator Stabilators are control surfaces which provide both horizontal stability and pitch control for the aircr
