A constant percent chord line is drawn from root airfoil to tip airfoil in linear interpolation method.(a) True(b) FalseThe question was posed to me by my school principal while I was bunking the class.The question is from Configuration Layout topic in division Configuration Layout and Loft of Aircraft Design

Answer»

The CORRECT choice is (a) True

For explanation I would say: Linear interpolation technique is used to create intermediate airfoil section as weighted average. To do so first both airfoils are connected with line. Next STEP is to draw a constant PERCENT chord line from root to tip airfoil. After following RESPECTIVE STEPS we will get airfoil section as per our requirements.
