FIELD: aviation; power engineering.

SUBSTANCE: system for maintenance of an aircraft with a nuclear plant (hereinafter – SMANP) located on the ground and underground is proposed, where SMANP points and subsystems, which are particularly dangerous from the point of view of biological radiation protection, are located underground, and landing of aircrafts with a nuclear plant on the take-off and landing surface is carried out with a pre-silenced reactor. An aircraft with a nuclear plant (hereinafter – ANP) is moved by a tow truck to points, where maintenance of it and its units and reactors is carried out, and such maintenance points are equipped with remote-controlled manipulators. At the same time, on the ground part of SMANP, the nuclear power plant is removed from the aircraft and lowered into a deep mine and placed in a quarantine isolation unit – a point equipped with radiation protection, where it is kept for a while for radiation levels to decrease, and then, the nuclear plant is maintained. There is a quarantine isolation unit at SMANP – a point for the decline of radiation activation of turbines and compressors. SMANP contains a hydraulic lift of ANP and nuclear seaplanes. On SMANP, there are elevated railway tracks to the mine with a lift, which is designed to move aircraft units. SMANP contains an inner transport subsystem for movement of aircraft units to their service points and storage facilities. In SMANP, there is a warehouse – an isolator for the safe storage of spare nuclear reactors. In SMANP, there are control and verification points of aircraft units and a stand for testing the operation of nuclear engines. In SMANP, there is a warehouse of compressors and turbines to be sent for repair, and there is a warehouse of backup nuclear engines. At the same time, SMANP, in its composition, has a loading dock chamber with a float-pontoon lift for ANP, which is installed on a pontoon platform of this lift. ANP is moved after landing from the runway to the upper level of the pontoon platform of the loading dock chamber by means of transportation on a special running robotic slipway conveyor, and ANP is transported by the same slipway conveyor from the lower level of the loading dock chamber to the premises of a maintenance workshop of ANP. The running robotic slipway conveyor, as a component of SMANP, carrying ANP, is equipped with upper side shields and a lower central radiation protection shield, and such protective shields can be transferred by means of drives to ANP protection positions and to positions of radiation protection removal, for example, for extraction of nuclear reactors from ANP airframe or before ANP take-off. To install ANP on its slipway conveyor or to remove it from the slipway conveyor, a lift for the running robotic slipway conveyor is installed on the aboveground slipway platform of SMANP, on which ANP moves and positions itself after its landing. Fencing structures of premises of the underground SMANP slipway platform and its reactor premises, in which nuclear reactors on molten salts are installed, and which are tested after their maintenance, are made with enhanced radiation protection, including sliding sluice gates of the loading dock chamber. In addition, there are points in SMANP for charging onboard batteries of ANP, ensuring ANP take-off and its possible emergency landing before the start of nuclear reactors. There is also a point in SMANP, in which nuclear reactors are installed to charge batteries of reactor machines of a system for counteraction to emergency situations of an aerial train (hereinafter – SCESAT). In addition, there is a warehouse of spare nuclear reactors on molten salts in SMANP. The group of inventions also relates to SCESAT; a system for conversion of heat energy of aircraft (hereinafter – SCHEA); an aircraft with a nuclear power plant; an aerial train consisting of a tractor aircraft and electrically towed aircrafts with electric engines; a nuclear aviation transport complex (hereinafter – NATC).

EFFECT: group of inventions provides economic efficiency in terms of a significant increase in carrying capacity and a relative increase in logistics capabilities for the delivery of goods and passenger transportation, while “maintaining” speeds characteristic of aviation; in addition, the use of the presented group of inventions in complex provides highly effective environmental safety and high economic efficiency of a new system.
