AIRPLANE STRUCTURE AND GEOMETRY
airplanes are powered fixed wing aerodynes . judging on numbers, they are most popular types of aircraft by far, and this chapter is dedicated to understanding their structure and shape.the most important part is the wing.
the winglet are not mandatory. some airplane types include them as standard (like the airbus A330), some have them as an option (like boeing 737-700) and others do not have winglets at all (like the boeing 737-300) . winglets improve slightly the fuel consumption for long flight, but they could have a detrimental effect on short flights. the slats and the flaps are so called especially during take-off and landing maneuvers. ailerons are control device . the sweep angle improves behaviour at high speeds, close to the speed of sounds. by correlating sweep angle and maximum speed for several types of airplanes
