MAE 155A Aerospace Engineering Design I Winter 2010 Homework #4A (Aircraft Design) DUE DATE: Thursday, 11 MAR 2010 Problem #1 The Last Known Position (LKP) for Air France 447 is (2.98 deg N, 30.59 deg W).# At the time of the accident, the airplane was enroute to waypoint TASIL (4.00 deg N, 30.00 deg W). (a) Compute maximum glide radius in all directions from LKP. Plot the radius and LKP in Google Earth. (b) Compute two trajectories that assume the airplane performs a gliding, 30 deg banked turn while attempting a return to Rio de Janerio along the flight path opposite to the TASIL waypoint. Plot the two trajectories (left and right turn) in Google Earth. weight at LKP = 450,000 lb (estimated) altitude at LKP = 35,000 ft (assumed) Airbus A330-200: S = 3,890 ft 2 , b = 198 ft, e = 0.84 #http://en.wikipedia.org/wiki/Air_France_447 Problem #2 Find the horizontal tail area that is needed for a twin- engine turboprop to achieve trimmed flight with center-of- gravity locations ranging from 0.5 to 1.5 ft.
