FIELD: transport.
SUBSTANCE: invention relates to aerostatics. Load-carrying structure of semi-rigid airship or orthostat includes central tunnel tube (1) of large diameter passing along central part of sheath throughout its length, circular or triangular strong frames (2) provided in cross-sections of sheath volume (10) where concentrated loads from chassis (8), rotor pylons (9) and system of diagonal-radial bracings (3) or longitudinal diaphragms rigidly interconnecting the central tunnel tube (1) and strong frames (2). The cockpit (4) is fixed directly on a butt of central tunnel tube (1).
EFFECT: increased rigidity.
