Abstract
Disclosed herein is an aircraft with engines positioned so as to avoid damage to other components of the aircraft. The aircraft may include a blended wing body aircraft. The engines may be positioned aft of a pressure vessel of the aircraft. The engines may be positioned aft of and/or above a fuel store of the aircraft. Such engine positioning may reduce the likelihood of damage to a pressure vessel and/or fuel store in the event of engine failure.
