I’ve seen normally friendly and warm Jalopnik writers come to clumsy, ineffective blows over the concept of car engine location. I came this close to poisoning another writer’s coffee after I heard them say something disparaging about rear engines, for example. It seems that the world of airplanes has some similar issues! There’s two major places airliners place their engines, and this video is one of the best explainers of why.
The two most common places for airliners to mount jet engines are under the wings or at the rear of the aircraft. I’m sure anyone who’s been to an airport has noticed this. The tradeoffs for each location are pretty fascinating, and, while this video by Mentour Pilot is pretty long, it’s very informative. Here, watch:
In case you’re seconds away from buying your first airliner and don’t have time to watch the video, here’s a quick pro/con breakdown of the two types:
Pro: Much easier engine access for service, can mount more and/or bigger engines, less structural reinforcing needed, shorter fuel lines, safer in case of engine fire
Con: High noise levels, susceptible to ground/foreign objects/debris damage, requires larger rudder (in case one engine is lost)
Pro: Quieter operation (from inside cabin), less likely to take in debris/foreign objects, more suitable to more kinds of runways/airstrips, can reverse aircraft on ground
Con: Harder to access for maintenance, requires more structural support and longer fuel lines, more dangerous in case of fire
There’s more in the video, of course, including much more detail about handling characteristics of each type of engine mounting.
It’s really interesting! Hearing a pilot talk about how planes handle makes aviation much more familiar to us ground-based gearheads.
