787 Engine Out During Flight Testing!

February 23, 2010 at 3:12 am | Posted in What's happing this week? | 1 Comment

So we had some interesting news (http://boeingblogs.com/randy/) over the weekend about the failure of the 787 engine during flight testing. I know this may seem like a bad thing, but its actually quite the opposite. While the pressure sensing equipment failed, this is not necessarily unexpected considering GE is releasing a brand new engine for the 787 (http://www.geae.com/engines/commercial/genx/). What this engine out showed is the airplane is able to sustain flight on one engine. This is great news for anyone who flies long distances over water!!!! For those interested in how a jet engine on a commercial aircraft works check out the video below (unfortunately, its kind of dull but very informative). As a quick overview, a jet engine compresses air, heats it up and expands it to spin a turbine and change the momentum of the air flow. According to Newton, a change in momentum equals a force (Force = mass x acceleration or Force = change in linear momentum). This is how an airplane generates a force with its engine.

What are your thoughts about this? Is this something that still worries you?

  1. More importantly, how did those pilots feel after that engine went out !! I guess this is what the testing is for right ? It’s so interesting to learn about what it takes to get a new plane to market.
