to Aerodynamics
B. The thrust of the aircraft is 120,000 pounds and the air density is .00048 slugs/cu.ft. The current cruising speed is 450 mph and we need to determine the drag coefficient of the aircraft. Find the Cd. (Hint: you may want to convert the original equation first) C. Weather conditions force the aircraft to descend to a level where the air density is .00076 slugs/cu.ft. The engine thrust increases to 250,000 pounds. At the new cruising altitude, what is the speed of the aircraft? (Hint: once again, you may want to convert the equation first)
After landing, the pilot switches aircraft. The new aircraft has a much different wing shape and things get a little more complicated. If you are ready for the challenge, try Drag Equation: Level 2. HAVE FUN !!!!!
