A side thruster module, comprises: a cavity-type body skin extending in a
longitudinal direction; a first thruster arranged in the body skin and
extending in a longitudinal direction; and a conversion nozzle arranged
in the body skin and extending in a radial direction perpendicular to the
longitudinal direction, for converting a direction of a thrust generated
from the first thruster in the longitudinal direction into the radial
direction. A large number of thrusters can be mounted at the side
thruster module thus to generate a high thrust, and the side thruster
module can be slim in the radial direction perpendicular to the
longitudinal direction.
