What is considered hypersonic speed in aerodynamics?
Q: What is considered hypersonic speed in aerodynamics?
A: In aerodynamics, any speed faster than Mach 5 (1,715 m/s at sea level) is considered hypersonic speed.
Q: How is hypersonic speed different from supersonic speed?
A: Hypersonic speed is different from supersonic speed in that air and aircraft act even stranger at hypersonic speeds than at supersonic speeds.
Q: Why is it important to distinguish between hypersonic and supersonic speeds?
A: It is important to distinguish between hypersonic and supersonic speeds because the behavior of air and aircraft is significantly different at these speeds.
Q: What is the speed of sound at sea level?
A: The speed of sound at sea level is 1,715 m/s.
Q: Can you give an example of a hypersonic speed?
A: Any speed faster than Mach 5, such as Mach 6 or Mach 7, is an example of hypersonic speed.
Q: Does the text mention any other important factors at hypersonic speeds?
A: The text only mentions that air and aircraft act very strangely at hypersonic speeds.
Q: What is aerodynamics?
A: Aerodynamics is the study of the motion of air and other gases and how they interact with objects in motion, such as aircraft.
