One of the inadvertent effects of the current pandemic has been a drastic reduction in global air pollution<\/a>. Amidst this unfolding tragedy, this paints a picture of what our future can be if we decide to continue on the path to climate change. <\/p>\n\n\n\n

It’s Not Easy Being Green<\/strong><\/h3>\n\n\n\n

The aviation industry is responsible for 12% of CO2 emissions from all sources of transport <\/a>and its primary source is the gas turbine engine. It\u2019s no surprise then that jet engine performance is a key driver in the development of more fuel-efficient and environmentally-friendly aircraft. <\/p>\n\n\n\n

Don’t Fail Me<\/strong><\/h3>\n\n\n\n

A second non-negligible factor is reliability. When the world recovers global air traffic will return and as always, aircraft will need to perform at peak performance:<\/p>\n\n\n\n

Airlines are unwilling to get out of bed for anything less than \u201c99.5%\u201d dispatch reliability, says Clark: \u201cWe are not in a business to deal with aircraft that don\u2019t function properly.\u201d <\/em><\/p> Flight Global<\/a> <\/cite><\/blockquote>\n\n\n\n

And one only needs to look at the delays currently to Boeing\u2019s 777X due to the engineering challenges<\/a> of the biggest turbine engine ever built.<\/p>\n\n\n\n

Manufacturers can address these jet engine performance challenges with Simcenter. If this sounds familiar it\u2019s because it is; the aforementioned issue with the Boeing 777X was due to challenges with variable stator vanes (VSV); we recently talked about t<\/a>he E-Break project<\/a> and VSVs using Simcenter 3D to reduce emissions.<\/p>\n\n\n\n

Get Better<\/strong><\/h3>\n\n\n\n

Engineering an efficient, robust & reliable jet engine starts with its thermo-mechanical performance. Register <\/a>to watch this on-demand web seminar on “Improving aircraft engine thermo-mechanical performance<\/a>” where we discuss how we can help address the thermo-mechanical challenges of aero-engines. These challenges can be summarized in three areas:<\/p>\n\n\n\n
