What should be the load factor if, lift coefficient is designed as 2.1 and aircraft is operating at dynamic pressure q as 20 Pa. Given W/s =12.(a) 3.5(b) 5.5(c) 3.25(d) 4.5I got this question in an interview.The question is from Selection of Thrust-Weight and Wing Loading topic in chapter Thrust-Weight Ratio and Wing Loading of Aircraft Design

Answer»

Correct CHOICE is (a) 3.5

The best explanation: Given, W/S = 12, lift co-efficient CL = 2.1 and q=20Pa

Now load factor N is given by, n = q*CL / (W/S) = 20*2.1/12 = 3.5.
