Flying wing:

"A flying wing is a tailless fixed-wing aircraft that has no definite fuselage. The crew, payload, fuel, and equipment are typically housed inside the main wing structure, although a flying wing may have various small protuberances such as pods, nacelles, blisters, booms, or vertical stabilizers.

Similar aircraft designs that are not, strictly speaking, flying wings, are sometimes referred to as such. These types include blended wing body aircraft, and microlights (such as the Aériane Swift), which typically carry the pilot (and engine when fitted) below the wing "
