1.	We are using the airfoil in the aircraft as _____(a) it is a streamline shape which provides better aerodynamics(b) it is a random shape can be changed to rectangular as well(c) it is easy to make than rectangular(d) it is not a streamline bodyI have been asked this question in an interview for internship.This question is from Airfoil Selection-1 in section Airfoil and Geometry Selection of Aircraft Design
Answer» RIGHT CHOICE is (a) it is a streamline shape which provides better aerodynamics Best explanation: Airfoil is a STREAMLINED body which provides MUCH smoother flow than non-streamlined body. Airfoil is DESIGNED in such a way that it can provide better aerodynamics than any other shape. Hence, in aircraft we use airfoils.
