Congratulations. You are hired as a structures engineer at Lockheed. Your first task is to determine if the new deluxe passenger airliner shown below is stable. Range is sufficient to cross the Pacific in a single flight. Wing area is 150 square meters. Chordwise distance between the wing effective elastic axis and aerodynamic center is 4 meters. Lift curve slope is 0.1/deg. The desired design envelope (Mach number versus altitude) is defined by the following bounding points. Design Envelope Mach = [0.1 0.3 0.8 0.8 0.4 0.3 0.2 0.13 0.1); % DesignEnvelope Alt = [ 0 0.0 10000 15000 12000 10000 8000 5000 O]: % meters Assume standard day for defining the design envelope.
D Question 1 20 pts Develop a MATLAB script called (divergence.m) to determine the wing divergence boundary (altitude versus Mach) to determine if the aircraft is stable. The script plots both the design flight envelope boundary and the divergence boundary on a plot of altitude on the y axis and Mach number on the x axis.
