Here are charts and drawings showing the components and major characteristics of KOUNOTORI (HTV.)
KOUNOTORI Components
KOUNOTORI is four meters across and about 10 meters long, a size large enough to accommodate a sightseeing bus. It consists primarily of three parts: (1) A propulsion module installed at the rear and composed of main engines for orbit change, Reaction Control System (RCS) thrusters for position control, fuel and oxidizing reagent tanks, and high-pressure air tanks; (2) An avionics module installed in the center part, with electronic equipment for guidance control, power supply, and telecommunications data processing; and (3) A logistics carrier that stores supplies.
