SOLVE IS AS SOON AS POSSIBLE. WITH IN 10 HOURS

A hovercraft in ground effect has the following aerodynamic forces expressed in body frame coordinates: X = Y = 0 Z = -mg + ZzZE L = L M = M theta theta N = 0 The body axes arc principal axes (Ixy = Ixz = Iyz = 0) and the angular momentum due to the engine/rotor is You can assume stability axes (w0 = 0) in addition to the reference conditions assumed in class. Begin with the nonlinear equations of motion (including disturbance torque h') in (4.7,1-5) and derive a set of small-disturbance equations of motion. Find the characteristic equation for the hovercraft in part (a). Show that, ignoring the rotor angular momentum H, the craft is statically unstable for M theta > 0 and L > 0. Show that this vehicle can be gyrostabilized (like a spinning top, i.e. solutions remain bounded) if H is large enough.
