Abstract

In order to perfect and standardize the current aircraft noise calculation method, this paper puts forward the basic theoretics of disassembling flight path based on geometrical elements of beeline segment and curve segment, builds a systemic and general aircraft noise calculation model. An example is presented to prove the feasibility and practicability of model. The model has solved some technical problems in the actual estimate of aircraft noise, standardized the calculation method and maken the whole assessing process more and more clear, intelligent and scientific.

Key words

aircraft noise / calculation model / disassembling flight path / effective perceived noise level
