Comparative Study of Ram Air Turbines based on Wind Tunnel Study for Specific Air Borne Energy Extraction

Ram Air Turbines (RAT) are used for emergency on-board power generation on aircraft and associated systems. Many studies usage of RATs have shown promising results in terms using as a source generation. external podded systems utilise self-sufficient adaptation. These pods generate their own requirements instead depending the mother power. Commercial cargo planes use generating hydraulic A RAT was suggested to be power, during failure main alternator prototype aircraft. specific requirement also produce high drag aerodynamic braking when deployed concurrently electrical energy. Three models with different solidity were studied wind tunnel at speeds suitability this drag-energy combination. This paper presents study. Based results, suitable selected further analysis ground trials.
