Fabrication and experimental studies on hybrid propeller engine

The increasing energy demand and rising fuel prices, create a revolution in hybrid-electric propulsion systems which have a potential to significantly reduce fuel consumption and increase the in the aviation industry. Hybrid-electric propulsion system takes over the advantage of both electric motor and internal combustion engine. A propulsion system in hybrid nature is developed using petrol engine and DC motor. A high torque DC motor is coupled with a 125 cc petrol engine to generate trust. The electric motor is turned on with the power of the 12V battery which is charged using a coil which is connected with the petrol engine crank shaft. The propellers are in both the engines. The flow rate over them is measured with the help of Anemometer. The Results are compared and studied. KEYWORDS: hybrid engine; electrical motor; petrol engine; propeller efficiency.
