Heat recovery through aircraft engine exhaust

Our aim is to utilize the hot air (CO2, NOX) released through the aircraft engine exhaust which contributes to global warming. By mounting the pipes inside the engine, hot air can be blown through the pipe and guided through the aircraft frame, where it can be used to produce electricity with the assistance of a Steam Electric Generator. Therefore it will be a thrust towards the future of sustainable aviation.

The challenge

Aircraft are the fastest-growing sources of emissions:- Domestic aviation emissions have risen by 17% since 1990, accounting for 9% of overall greenhouse gas emissions, and CO2 is the largest component of aircraft emissions, accounting for approximately 70 % of the exhaust. When it is emitted from other fossil fuel combustion sources, as well as nitrogen oxides (NOx) from aircraft engines and global air traffic at cruising altitudes, the gas blends with the atmosphere. This causes adverse effects on the composition of the atmosphere, in particular with respect to ozone formation in the upper troposphere and lower troposphere. As a result, these are responsible for the greenhouse effect, which contributes to global warming and has a direct impact on our climate. As a consequence, it is our duty to make sustainable aviation a reality.

The solution

Our proposed solution for this modern complication is to utilise the steam (CO2, NOX) released through aircraft engine exhaust by retrofitting the pipes inside the engine where the integration of hot air will be blown into the aircraft structure and with the assistance of steam electric generator it will directly convert it into electricity for supplying electric current in the obligatory area. The idea is to use the energy from the exhaust to increase power output. It could also dramatically limit pollutants emissions and use of both CO2 and NOX toxins, both of which add to global warming. This approach ultimately offers greater potential and economic feasibility. So by this solution sustainable aviation would be a reality.
