The Boeing B-52H Stratofortress is a long-serving, long-range, jet-powered strategic bomber of the United States Air Force. The BUFF, as it is nicknamed, has a wingspan of 185 ft and a planform area of 4000 ft2. It has a parasite drag coefficient of 0.0119 and an Oswald efficiency factor of 0.86. It is powered by eight Pratt & Whitney TF33 turbofan jet engines with a thrust specific fuel consumption of 0.78 lb fuel/lb-hr. The BUFF carries 300,000 lb of fuel and it weighs 188,000 lb without fuel. On a typical mission, it is flying at 35,000 ft and flight Mach number of 0.82. At that altitude, the ambient density and temperature are 7.38210-4 slug/ft3 and 394 °R, respectively. A) Find the range of the B-52H at this flight condition, in miles (1 mile = 5280 ft), on a full-tank of fuel. Use an average weight of 338,000 lb for calculations requiring a single weight value. Answer: = [R] mi (round your answer to the nearest integer) B) Find the maximum range of the B-52H at that altitude, in miles. Answer: = [Rmax] mi (round your answer to the nearest integer) C) In the 50s and 60s, they would often have nuclear-armed strategic bombers constantly in the air (in case they need to strike at a moment’s notice). Find the maximum endurance, in hours, of a B-52H ‘patrolling’ at 35,000 ft. Answer: = [Emax] hrs (round your answer to the nearest integer) D) At what flight Mach number would the B-52H need to fly for maximum endurance? Use an average weight of 338,000 lb for calculations requiring a single value for weight. Answer: = [M] (round your answer to two decimal places)
