1) Considering the earthfixed reference frame OEXEYEZE, choose correct answer(s) for the Euler angles o, e and y which can be defined/transformed by rotations about the following axes of the bodyfixed reference frame OBXBYBZB in the following order: (a) (b) (d) 2) Which of the following statement(s) is (are) correct? (a) (b) (c) (d) (e) Xaxis, Yaaxis and Z;axis. Zaxis, Yaxis and Xaxis. Yaaxis, Xaxis and Zäaxis. Xaxis, Zaxis and Yaxis. 3) During a flight test an aircraft initially performs a steady straight and horizontal flight. At a certain moment the aircraft is excited by a pulseshaped rudder deflection. The roll rate (p) and the yaw rate (r) responses are represented as a function of time t. After some time, both time histories resemble a damped sinusoidal response. (a) (b) Static stability is a necessary condition for dynamic stability. The Dutch roll's damping can be increased by enlarging the dihedral I. Enlarging the vertical tailplane results in a higher damping of the Dutch roll mode. In general, increasing the static directional stability results in an increased spiral stability. After a disturbance, an aircraft with a stable Dutch roll mode will return to its initial flight condition. Which of the following statement(s) is (are) correct? (d) (e) The period of p is significantly larger than the period of r. The period of r is significantly larger than the period of p. The phase of p is equal to the phase of r. The time to damp to half amplitude of p is equal to the time to damp to half amplitude of r. The frequency observed in the response of p is equal to the frequency observed in the response of r. 1) Considering the earthfixed reference frame OEXEYEZE, choose correct answer(s) for the Euler angles o, e and y which can be defined/transformed by rotations about the following axes of the bodyfixed reference frame OBXBYBZB in the following order: (a) (b) (d) 2) Which of the following statement(s) is (are) correct?
