During the requirements review (b) katherine discussed the upcoming design project with his functional team managers. sHe realized that his previous task table is useful, but does not capture some important task interdependencies: After a first pass through fuselage, wing and empennage design (f,g,i), the vehicle layout (d) has to be refined. While avionics design (h) may be started without being constrained by initial fuselage design (f), it must be assured that the avionics suite will actually fit into the fuselage, requiring iteration between (h) and (f). The ground testing (m) is conducted primarily for two purposes. First, a mechanical ground test will reveal the wings modes of vibration. If the wings turn out to be too flexible, a stiffening of the wing structure (g) has to be considered. Secondly, electronically enabled functions provided by the avionics suite (h) such as actuation of the flight control surfaces will be verified. Some adjustments to the avionics suite (h) are usually required to fine tune the system before first flight as a result of these tests. Rather than test flight worthiness, the main objective of flight testing (n) is to verify that both the engine and payload perform according to their respective specifications (c,e) in a realistic flight regime. Some non-compliances discovered during flight test must result in revisions of engine specification (c) and GFE payload interfaces (e), respectively, with subsequent delivery of revised engines and payloads. 3) (30 points) Modify the DSM to reflect these interactions and briefly comment on the changes. 4) (30 points) Convert your DSM to a binary matrix {using 1,0} and multiply the matrix with itself 4 times. Describe the result of each sequential multiplication and draw some conclusions (e.g. DSM, DSM2, DSM3, DSM4)
