Recently, collapsed bridges, belonging to infrastructure networks, evidence the needs of reliable monitoring and inspection routines. Inspections can be a challenge operation in sites difficult to access; specially trained staff like industrial climbers perform the inspection routine, eventually involving large under-bridge units, elevating platforms, or other specialized equipment. In addition, since the inspections are performed manually, the outcomes mainly rely on inspector confidence and experience. This paper discuss the possibility of using unmanned aerial vehicles for monitoring and inspection of transport infrastructure.

Currently, the problem of ensuring safety of flights of unmanned aerial vehicles (UAVs) over the territory of transport infrastructure facilities (TIF), primarily airports, remains topical.In one of the previous works, the author together with the co-author proposed a method for increasing safety of movement of unmanned aerial vehicles and the system for controlling the routes of unmanned aerial vehicles (hereinafter – route control system, RCS) that implements it, which makes it possible to improve safety and security of UAV traffic at transport infrastructure facilities by limiting UAV traffic area strictly to a dedicated air corridor (DAC). The development of this system creates the prerequisites for removing the existing restrictions on the use of unmanned aerial vehicles at transport infrastructure facilities.For practical implementation of the proposed system, it is relevant to develop a method of placing RCS at transport infrastructure facilities. This condition can be justified by the fact that RCS, as a rule, will be located under conditions of dense infrastructural development, including dangerous technical elements of technical equipment, a collision of a UAV with which can lead to an emergency situation (ES); besides, the movement of air/ground vehicles will be carried out in the immediate vicinity of RCS along transport routes/corridors, and employees, passengers and visitors of TIF will move along the pedestrian paths.The objective of this study – to develop a methodology for placing systems controlling routes of unmanned aerial vehicles at transport infrastructure facilities.The study conducted with well-known scientific methods, including the basic routing problem posed by Dantzig and Ramser, modelling, analysis, and synthesis, made it possible to develop a method for placing RCS for unmanned aerial vehicles at transport infrastructure facilities. The practical application of the proposed methodology makes it possible to build routes for movement of UAV at TIF, to form a network of dedicated air corridors for UAV at TIF operated in relationship with the system, determine the optimal location of the RCS elements at TIF.

The shortcomings of classical methods for inspection of transport infrastructure objects have led to the development of more efficient, more reliable, faster and cheaper procedures for condition assessment and load-bearing capacity and service life estimation of objects. In this context, different autonomous systems developed in the last decade have the most notable role and their development is continuously speeding up. This paper provides a state of the art review of the unmanned aerial vehicles application for structural inspection with a focus on bridges. The paper comprises the following: a review of the current regulations prescribing the types and frequency of inspections; a review of the current classical inspection methods with their advantages and disadvantages; analysis of advantages and disadvantages in application of unmanned aerial vehicles for bridge inspections and a review of the equipment commonly used in their development.

Analysis And Synthesis

Unmanned aerial vehicles (UAV), also known as drones, are gaining more and more practical application in modern society, particularly as the tools of implementation of the concepts of «smart city», «smart health care», «smart industries», Internet of Things, 3D mapping, digital transport. But currently it is impossible to use of UAV at certain objects, comprising objects of transport infrastructure (OTI), primarily, airports, because of existing restrictions due to security threats arising during the UAV flight.The authors of the present work have set a goal to offer a solution that allows to start operating UAV at transport infrastructure facilities that are currently prohibited for UAV flights. To achieve the objective of the work, using analysis and synthesis, comparison and generalization, factors and conditions for safe use of UAV at OTI have been formulated, a method for increasing security of UAV flight has been developed, followed by the suggestion on the UAV route control system.The proposed system makes it possible to safely use UAVs at OTI by restraining their flight area strictly to the designated corridor, which eliminates a threat of a collision of UAV with other vehicles operated at OTI, dangerous elements of OTI, as well as with people at the object.The system does not need electric power feeding, which makes it possible to implement the system without creating an auxiliary power supply infrastructure.The practical application of the proposed system and, as a consequence, implementation of a greater number of opportunities for the use of UAV, are capable to generate fundamentally new technological processes and structures at transport facilities, which is one of the directions for creating the next generation transport infrastructure based on IoT and artificial intelligence.

Nowadays, the creation of remotely-piloted aerial vehicles for various purposes is regarded as one of the most relevant and promising trends of aircraft development. FAU "25 State Research Institute of Chemmotology of the Ministry of Defense of the Russian Federation" have studied the operation features of aircraft piston engines and developed technical requirements for motor oil for piston four-stroke UAV engines, as well as a new engine oil M-5z/20 AERO in cooperation with NPP KVALITET, LLC. Based on the complex of qualification tests, the stated operational properties of the experimental-industrial batch of M-5z/20 AERO oil are generally confirmed.
