A whopping 50-70 per cent reduction can be achieved in particle emissions by using biofuels in jets engines in aircraft – a new study by NASA has claims.
NASA along with the German and Canadian agencies carried out study to prove the benefits of bio-fuels in jet engines in context of environment and airline economics combined. This study which was named Alternative Fuel Effects on Contrails and Cruise Emissions Study (ACCESS) carried out a series of flight tests in 2013 and 2014.
Scientists involved with the study collected data from the engines, which used a 50-50 blended alternative fuel. The data included statistics like engine performance, soot particles emissions and contrail generation at altitudes similar to those flown at by commercial aircraft.
Contrails, generated by the aircraft engines when mix with the cold air in the atmosphere, cloud formation takes place which has an impact on the environment.
The tests were conducted on flights having NASA’s DC-8 engine which was flown at a height of 40,000 feet, which had a 50 percent proportion of biofuel. To study the emissions and contrail generation, three flights were made to fly in turns behind the aircraft with DC-8 engine. These research aircraft flew at a distance ranging from 300 feet to 20 miles.
According to Rich Moore who led this study, it is first of its kind quantification where an engine with a bio-fuel has been studied for various results like soot emissions and contrail formation. This study published in Nature journal, consisted an eminent panel of experienced team members and hi-tech equipment to get accurate results in this highly significant investigation.
This study shows that the usage of bio-fuel in jet engines has an economical consideration as well along with its environment friendly characteristics.
