Why can’t helicopters fly fast?
The helicopter will run into what’s known as flow separation boundary where it can no longer compensate for its unequal lift. That point comes at around 400 km/h (216.45 knots, 249.09 mph). With counter-rotating rotors, sometimes helicopters can go faster. But even they can only push against flow separation so much.
What limits the top speed of a helicopter?
Two main issues restrict the speed of rotorcraft:
- Retreating blade stall. As forward speed of the helicopter increases, the airflow over the retreating blade becomes relatively slower, while the airflow over the advancing blade is relatively faster, creating more lift.
- Transonic drag near the rotor blade tip.
What does it mean when a helicopter is circling at night?
