The altitude test facilities at RAE Pyestock are used in support of clearance of aero-engines, intakes and helicopter rotors to operate under severe icing conditions. An important aspect of the work is the simulation of the wet icing cloud in terms of water concentration, mean droplet size and spectrum. Water spray rakes or booms have been developed for this activitiy and individual nozzles calibrated in a purpose built wind tunnel. A laser particle sizer has been used to calibrate typical spray nozzles and attempts made to establish a traceable standard. Although this paper mainly deals with the development of cloud simulation it also includes a short description of the facilitates and the capability for monitoring ice formation and shedding.
