Please answer all parts of the question below.
Question 1 Consider the typical wing and tail configuration of an aircraft as shown in Figure Q1. CG БАС L МАС W Lt XCG XAC Figure 01 (a) ХcG Prove that Pitching Moment about CG, CM, can be expressed as follows. ext ХАС CM = CM AC + Cut where c is the chord length. (5 marks) = - XCO) - C, FAC - Xco, (6) What is the trimmed tail lift coefficient? (5 marks) (C) Formulate an expression for Xcg such that the aircraft is positively stable. (5 marks) (d) Analyse the CG location when the aircraft is neutrally stable. (5 marks) Derive an expression for the aircraft stability margin for a given Xcg (5 marks)
