1.	My fuselage has length of 10.12m and volume of 8m^3. Now if I want to design same fuselage but with volume of 16m^3 then, what should be the length of fuselage? Given, all others parameters are held constant.(a) 5.06m(b) 1012cm(c) 1000mm(d) 6.025mI had been asked this question in exam.The doubt is from Configuration Layout in division Configuration Layout and Loft of Aircraft Design
Answer» Right choice is (a) 5.06m Best EXPLANATION: GIVEN, LENGTH of old fuselage L1 = 10.12m, volume of old fuselage V1 = 8m^3. Now, we are asked to design same fuselage which has volume of 16m^3. Hence, new volume V2 = 16m^3. Internal volume V is inversely proportional to length L of the fuselage. Here, we have been asked held all other PARAMETERS constant. Hence, L2 = (V1/V2)L1 = (8/16)10.12 =5.06m^3.
