Vibration isolation of a LASER fluorosensor system mounted on a Puma helicopter

A simple isolation system, based on passive pneumatic isolators, was design ed and developed for mounting a Laser Fluorosensor on a Puma helicopter. Th e vibration characteristics of the helicopter were measured during a wide r ange of flight attitudes, including taxi mode, take off and landing. The ch oice of pneumatic isolator and the design of the Laser Fluorosensor mountin g system were based on the results of the vibration measurements. A customi zed power spectral density (PSD) analysis procedure was used to determine v ibrational frequencies and their amplitudes.
