Rotorcraft Noise Model (RNM), Version 7(LAR-17753-1)
Rotorcraft Noise Model (RNM), Version 7
The RNM simulation model calculates community noise, computing time histories of noise for arbitrary vehicle flight operations. The technology accommodates multiple noise sources (e.g., rotors and engines), each represented by a sphere of spectral data at a reference distance. Propagation to the ground accounts for spherical spreading, atmospheric absorption, ground impedance effects, and limited weather effects.
Notes: NOTE: RNM is legacy code and does not come with any technical support
