1.	Scaling factor of turboprop engine is 1.2. If, the actual length of an existing turboprop engine is 12 unit then, what will be the length of scaled engine?(a) 23.68(b) 56.6(c) 12(d) 32This question was addressed to me by my school principal while I was bunking the class.This interesting question is from Propulsion topic in section Propulsion and Fuel System Integration of Aircraft Design
Answer» CORRECT option is (a) 23.68 For EXPLANATION I would say: Given, scale factor SF = 1.2, Actual LENGTH L = 12 unit Now, Length of the scaled engine l = LSF^3.73 = 121.2^3.73 = 23.68 unit.
