Helicopter Blades Break Sound Barrier at Natalie Hawes blog

Helicopter Blades Break Sound Barrier. The most important reason is that propeller doesn't spin faster than the speed of sound, because of drag, aerodynamic disturbance and sound production. Indeed, when a blade approaches. This is also why most tip designs have included tip sweepback in most bigger helicopters with longer blades, as you can see on the aw169 in the picture below. So quickly, in fact, that the. But this illustrates how badly helicopter vne is dictated by the speed of sound. There is also a compromise between rrpm and disc diameter. Considering that the blade rotation speed is constant at 800 km/h (on average), we have defined a “typical” sound barrier for helicopters at 400km/h. The only way to get the tips to break the sound barrier would be to move the helicopter forwards very quickly. The chopping sound comes from the blade chopping through the turbulent flow from the. They don’t break the sound barrier in most operating conditions.
