Abstract. Aircraft icing is one of the main factors decreasing the flight safety. Qualitative and quantitative understanding of the icing process is crucially needed for developing anti-icing measures and safety recommendations. Changes in aerodynamic characteristics of aircraft caused by changes in shape of aircraft surfaces due to the ice accretion can lead to significant aerodynamic performance degradation. So the reliable and accurate information of how the shape of the ice accretion influences on aerodynamic characteristics is a key point for predicting the changes in aerodynamic performance.The study addresses to a problem of accurate shape measuring of ice accretion for further experimental study of iced-aircraft aerodynamic in a hydrodynamic tunnel. For this purpose the evaluation of various techniques of ice 3D measurements is performed that include as visible so thermal imaging of ice accretion. The results of evaluation serves for the decision of preferable technique to be used in experimental study. Also the framework is developed for creating physical models of iced aircraft based on result of real ice accretion shape measurement. It allows to produce stereolithography (SLA) copies of of an aircraft under icing condition for different levels of icing. These SLA-models of an aircraft under icing condition are then used for flow behaviour study in order to identify critical flying condition.

The flow distribution within a reduced scale model pipeline to study and determine the best splitting device for a horizontal pipeline through experiments were conducted. In this research, five splitting devices are designed and tested on the model rig. Out of five, only one splitting device has been chosen that achieved the objective the best; to improve airflow to be a homogeneous flow in the pipe, or at least reducing and improving from the roping condition. The process of selecting the best device had been done through qualitative analysis of velocity profile and airflow distribution obtained from Pitot Tube measurements, besides the airflow pattern and behavior through PIV results.
