The experimental Oblique Wing Aircraft (OWA) has a wing that pivots, as shown in Figure P8.17. The wing is in the normal unskewed position for low speeds and can move to a skewed position for improved supersonic flight [11]. The aircraft control system loop transfer function is
(a) Sketch the Bode diagram, (b) Find the frequency oil when the magnitude is 0 dB, and find the frequency ω2 when the phase is -180°.
