1.
torso, trunk, body
The main part of the human or animal body excluding the head, arms, and legs.
2.
fuselage, body (of a vehicle or aircraft)
The main body of an aircraft, ship, or other vehicle, excluding wings, tail, and other appendages.
Usage
For the body sense, 胴体 refers specifically to the trunk — the core body minus limbs and head. This distinguishes it from 体 (the whole body) and 胴 (the torso in martial arts or armor contexts).
For aircraft, 胴体 is the standard term for the fuselage, parallel to English aviation terminology.
