A Blended Wing Body aircraft looks something like this:
In fact, every true BWB concept model I've seen puts the engines in the rear. Why is this? Can't they be hanging from the wings on pylons?
I'm envisioning a large cargo aircraft, if that maters. In fact I'm considering turboprop engines for even better fuel efficiency, so you could theoretically put one of them on the nose.
Is there something about BWB geometry that greatly favors rear engines? Wikipedia says the body can generate its own lift. Does that mean the airflow is faster over the top and therefore you get greater intake mass flow at the top of the tail area?
