Hybrid powered aircraft jet engine is a hybrid aircraft concept where engines will be run based on of water and solar power. the oxygen and hydrogen gases generated through electrolysis will be used to power the jet engine. another option is to use solar powered electric motors as a propulsion mechanism. the proposed solution emphasizes on the use of environment friendly form of propulsion. implementing this system will enable us to reduce the cost of operation of flights and aircraft engines will be less polluting and it will create a lot of direct and indirect job opportunities. description of the problem: the major adverse effects of aircrafts on the environment are air pollution and noise. the exhaust of an airplane’s engine consists of harmful gases like sulphur and nitrogen oxides and also carcinogenic substances like benzene and formaldehyde. these gases lead to several other environmental problems and also have an adverse effect on the human health. the cost of this dangerous fossil fuel is also high. hence, resorting to cheaper and renewable forms of propulsive devices provided that they are environment friendly is the solution to this problem. description of the design process: in this design process, the aircraft engines will powered by two methods, 1.electrolysis method electrolysis of water will be carried out in a water tank with separate compartments for the anode and the cathode. aluminium electrode is used as anode and stainless steel electrode is used as a cathode. these electrodes are connected to a battery using copper wires. to boost up the rate of hydrogen generation, catalysts like syngas and titanium powder are added. when current flows through the circuit, hydrogen gas will evolve at the anode and oxygen gas will evolve at the cathode. these gases will be collected and stored in separate tanks that will be fitted with zigbee sensors to monitor the rate of generation, consumption and level in the storage tank. these oxygen and hydrogen gases will be supplied to the jet engine, where they will be mixed and burnt to produce thrust. calculations  sea water = 25,000 litres  hydrogen generation per second = 0.00294 m3  total volume of hydrogen gas = 30875 m3  weight of hydrogen gas = 2.7756 x 106 g 2.solar powered method another option is to use electric motors as a propulsion mechanism which will be powered by solar cells. 580 photovoltaic cells having a capacity of 60 kw will be placed over the wings and the fuselage. the solar energy from these cells will be stored in lithium ion batteries. totally, 8 lithium ion cells with a potential of 120 v each will be used for this purpose. these cells will power the electric motor for generation of thrust. a dynamo can be connected along with the motor which will save some energy in a separate cell for emergency operation. description of the proposed solution: the proposed solution emphasizes on the use of environment friendly form of propulsion for aircraft like through electrolysis of water and through solar cells that have almost zero emissions. power required for the hydrogen gas will be renewed using solar power continuously. potential benefits of the solution: implementing this system will enable us to reduce the cost of operation of flights, manufacturing cost, fuel cost & hence, there will be a simultaneous fall in the price of travel. hence, more people can travel through air. in case engine design is not perfect also at the same time combustion will take place by this project. by this solution the aircraft will become more efficient and less polluting over time. opening up of industries for manufacture of the hybrid hydro solar power aircraft engines and components will create many direct and indirect job opportunities.
