1.	Which of the following is not an application of an airfoil?(a) To provide thrust for acceleration(b) To provide lift(c) To provide lift co-efficient(d) To provide streamlined flowI had been asked this question in quiz.This interesting question is from Airfoil Selection-2 in chapter Airfoil and Geometry Selection of Aircraft Design
Answer» The CORRECT choice is (a) To provide THRUST for acceleration To EXPLAIN: In an aircraft, engines are used to provide thrust for acceleration. Airfoil is used to provide lift, to improve certain flow characteristics. Streamlined flow is ALSO produced by an airfoil.
