Keywords: helicopter, blunt body wake, drag breakdown

Reduction of emissions is one of the challenging tasks for aeronautical engineers today. This paper redounds to this challenge by providing flow characteristic and drag analysis of a light weight utility helicopter. Thereby, the potential for systematic design optimisations is identified to reduce helicopters environmental footprint and increase their productivity.
