The velocity of supersonic air as it flows through a divergent nozzle

  • is inversely proportional to the temperature.
  • increases.
  • decreases.
Jordi asking:

why is it increasing?It isnt convergent,it is divergent.Can someone help?

Can someone please tell me what is Vmd?

Module 8. Basic aerodynamics

On a high winged aircraft, what effect will the fuselage have on the up-going wing?

  • The up-going wing will have a decrease in angle of attack and therefore a decrease in lift.
  • The down-going will have a decrease in angle of attack and therefore a decrease in lift.
  • The up-going wing will have an increase in angle of attack and therefore a decrease in lift.
Jordi asking:

can someone please explain this?I thought it was c

  • flows towards the root.
  • flows chordwise from leading to trailing edge.
Jordi asking:

why not towards the tip?
