What the Prince William helicopter?
an RAF sea-king helicopter
What is a floating helicopter?
the Sikorsky sea king.
How fast is the gazelle helicopter?
125 kts in the cruise. 168 kts top speed (at sea level 15 degrees celcius)
What will replace the sea king helicopter?
The EH 101 Merlin replaces the Sea King in many navies and air forces
Can a cobra helicopter break the sound barrier?
No, a Cobra helicopter cannot break the sound barrier. The maximum speed of a Cobra helicopter is around 185-190 mph, which is significantly lower than the speed of sound (about 767 mph at sea level).
Who invented the sea king helicopter?
You can't really invent the same thing several times. The Sea King helicopter isn't rated as an invention, as it's not really doing anything hugely new. It was developed by a team of engineers from a company called Sikorsky.
What kind of helicopter is Marine One?
It is the VH-3D Sea King but is scheduled for replacement in the near future.
Witch helicopter is faster the ch124 or the ch146?
The CH124 Sea King, at 151kts max indicated airspeed. The CH146 Griffin is 140kts.
What is the top speed a sea ray 175 boat will reach?
38 knots
What is the speed of sound in air at sea level?
The speed of sound has nothing to do with the sound pressure, like "at sea level" or on top of a mountain. But the speed of sound has very much to do with temperature. Scroll down to related links and look at "Calculation of the Speed of Sound".
Why has there been a Sea King helicopter flying low over Burlington and Hamilton Ontario?
Flying truck tire killed woman on qew near maple view mall
What is the theoretical max speed of a helicopter?
The theoretical max speed of a helicopter is based on the speed of the main rotor through the air, since conventional airfoils essentially quit lifting at close to the speed of sound. Knowing that, let's assume the main rotor's tip speed moves through the air at 400 mph while in a hover. Now, as the vehicle begins to move forward, that forward motion is added to the existing tip speed. Since the speed of sound at sea level is around 750 mph, our example bird shouldn't be able to go any faster than 350 mph. Realistically, our example wouldn't be able to travel even that fast, since air traveling across an airfoil (the main rotor) accelerates across the top surface, thus cutting into our theoretical top speed. That being said, airfoil design is constantly evolving, allowing incremental improvements in efficiency, speed, and noise reduction.
