1.	The main motive behind redesigning standard airfoils to get the new airfoils was higher maximum lift coefficient and______(a) Lesser drag(b) Better shapes(c) Handling flow separation effects(d) Strength of materialI have been asked this question during an interview for a job.Question is from Modern Low Speed Airfoils topic in division Incompressible Flow over Airfoils of Aerodynamics
Answer» Correct option is (c) HANDLING flow separation EFFECTS The explanation is: The use of computers led to the design of better airfoils since it made POSSIBLE to get the definitive properties of the airfoils. This had many advantages like a HIGHER coefficient of lift and shape to tackle the flow separation effects at high ANGLES of attack.
