Unformatted text preview: ASE 367K Final Exam 200 Points Closed Book 1. (30pts) Starting from the definitions of ~locity, acceleration, and mass flow rate and Newton's law, derive the equations of motion"fOrnonsteady fligh"tin a vertical plane over a flat earth at constant altitude. Begin by drii\Vinga 'fiee ooo.y diagram Ofan airplane in constant altitude flight, Finally, how mapy,degrees of freedom does this set of equations of motion have? \ fI.\.. { (7 r' t \ 2., (30 pts) Consider quasisteady flight at constant altit!!.de with 88 small, Te« IV, T = T(h,P}, C = C(h), and a parabolicdrag polar with constant coefficients. At what velocity should the airplanebe flown to maximize the range? 3. (20pts) If an aircraftis flowninconstantaltitudecruiseat the speed V = V E ,how far can it , ..... fly with a given amount of fuel. Use the same approximations as in Problem 2. 4. (45pts) An aircraft is flying at a constant altitude h = 30,000 ft. (p =.0009 slugs / fr3) and at a constant velocity V =7,00 ft/sec. The airplane has a planfonn...
