Develop the equation of motion for an airplane that has freedom only along the
path; that is, variation in forward speed. If the airplane is perturbed from its
Equilibrium state what type of motion would
you expect? Clearly state all of your
Define floating tendency and restoring tendency in the case of stick
Stability and derive an expression for control surface angle.
What are the two necessary criteria for l
ongitudinal balance and static stability?
Explain with neat sketches.
Derive an expression for the
oating angle of the elevator of an airplane at a given
tail angle of attack
and air speed V, in terms of the aerodynamic, geometric and
ties of the elevator.
Show with two examples, that the lateral and directional dynamics of airplane are
Strongly coupled. Explain from the characteristic equation of lateral
Dynamics, the types of oscillations of the airplane.
How are the
