Comparative Noise Levels

[naseemlatif]

I have to complete an introduction to the neighborhood government about the plausibility of setting up a helistop inside a metropolitan region.

Does anyone have the information on noise levels from various helos in their diverse classes? Precedent AS350,EC130,A119&B407 as a comparable classification/class. In the event that conceivable identifying with ICAO and GCNP edges in overflight, landing and T/O.

Your information/help energetically anticipated!

When it comes to helicopters, the rotor head is known as the part of the rotor rally that links the blades to the trough, cyclic and collective mechanisms. It is also known as the rotor hub. We can say that an articulated rotor head system is one where the separate blades are able to lap, lag and alter pitch. This is possible by raising the blades on flustering and lagging hinges and pitch alter bearings. While a semi-rigid rotor head does not have separate flapping or drag hinges but gives for flapping and lag motion via gimbal mounting. It is something like a teetering rotor head that is found on the Robinson family of helicopters. We can say that a rigid rotor head has no flapping or lag hinges but have a pitch change capacity. It’s flapping and lagging movement is managed by flexible sections that are at the blade root or blade attachment. The time when you are utilizing merged blades, the blades can also flex to offer a flapping motion.
