sound' right now. Here's why," states: ● A news article¹ titled, "Transatlantic airplanes are flying at the speed of How are these flights able to fly at the speed of sound? Specifically, accurately explain: What does it mean "reaching speeds equivalent to that of sound"? What does it mean "reached up to 778 MPH"? ● The jet stream over the Atlantic so strong that flights heading from the US to Europe are reaching speeds equivalent to that of sound. Passenger aircraft traveling east from the US across the Atlantic have reached up to 778 MPH. That's a little over 200 miles per hour faster than normal cruising speeds. ● Extra Credit: If these conditions persist, and an airplane flies in both the east and the west directions to complete a round-trip, does the overall round-trip time increase or decrease relative to the case of no jet stream? Estimate by how much the overall round-trip time changes during a 4,000-mile trip between the east coast of the United States and Europe with the jet stream as compared with no jet stream. Now assume that these "new" jet stream conditions are permanent. What is significance for MCR, Mdrag-divergence, C₁/CD, CD.i, AR, a, TSFC, etc.? If you could, what type of design changes, if any, to the airfoil, wing, and airplane would you recommend given these new conditions? sound' right now.

Answer rating: 100% (QA)

Reaching speeds equivalent to that of sound means that the aircraft is traveling at or near the speed of sound which is approximately 767 miles per ho... View the full answer
