About 200 mph.
No helicopters can break the sound barrier. The fastest speed achieved be a helicopter is 249 mph.
Theoretically, the light would be very slightly blue-shifted because the helicopter is coming closer to you.
the fastest speed ever is 12874.97 mph
The speed of light is fastest in a vacuum. All other media slow the speed of light down, albeit very slightly.
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
No helicopters can break the sound barrier. The fastest speed achieved be a helicopter is 249 mph.
Currently, the fastest helicopter in the US military is the CH-47F Chinook with a top speed of 196 mph (315 kp/h).
The world's fastest is the Eurocopter X3 , which flies at 300 mph. -( The Apache flies at 227, and Bell's Viper at 255. )
Theoretically, the light would be very slightly blue-shifted because the helicopter is coming closer to you.
Lynx ZB-500 249.09 mph world record. Fastest helicopter.

Helicopter?
thefastest helicopter in the world presently is the apache of the us armyDefinitely not, it is the Chinook of the us army. The Chinook is a transport plane, it doesn't use a tail roter, only the from one wich produces more speed.
The fastest car is faster than the fastest police helicopter. However, cars are generally limited to roads and traversible ground, whereas a helicopter can fly a straight line from point A to point B. There are several instances of criminals with fast cars who have managed to lose police helicopters in pursuit. However, they pale into insignificance against the criminals in fast cars who don't. The physics of any rotary wing propulsion device restricts it's forward speed to around 250 mph. The fastest helicopter in the world currently is the Westland Lynx with a maximum forward speed of 249.10 mph.
Helicopters created nowadays generally have 2 or 3 blades. The fastest recorded helicopter has 3 blades. as it revolves more pressure is put forth and therefore the helicopter travels faster
None. The world's fastest helicopter only measured 249.1 mph.
