The three-view drawing at the bottom of the page
shows the general layout of the Boeing 747 aircraft. For the purpose of estimating the longitudinal aerodynamic characteristics of the vehicle, we

Exercise Set III
1. Use the dimensions provided in Exercise Set II for the Boeing 747 aircraft to estimate the values of Cm q
and Cm for both ight conditions of Exercise Set I. Refer to Solution Set I for any additiona

Exercise Set II
February 21, 2011
We continue our study of the Boeing 747 aircraft. We will want to use some of the results
from Exercise Set I, so they are summarized here (so that we all use the same values as a
starting point).

We will consider using state-variable feedback to improve the lateral-directional response of the
Boeing 747 aircraft, particularly the Dutch Roll mode. Assume initial trim conditions corresponding

Exercise Set VI
Create a MATLAB code, similar to the one you wrote for Exercise Set V, to treat lateral-directional motions.
First, compute the dimensional stability derivatives from the following dimensionless variab
