“…To date, there are no systems based on microphone arrays or fiber-optic sensors that, would drop, according to the information received from them. Such systems are not used due to their possible danger and high weight, but their presence when dropping a bladder type fuel cell can minimize the risk of loss of both aircraft and passengers [3][4][5].…”

To date, there is a problem with the safe operation of aircraft, namely with the safe evacuation of people in flight mode and during their landing from aircraft. The article discusses aspects of the use of fiber-optic and aeroacoustic technologies built into the general concept of a fiber-acoustic control system for assistance in safely jettison or dropping a bladder type fuel cell from a helicopter fuselage in an aviation emergency. The ability to control the parameters of speed, temperature, acoustic and optical noise, in case of deviation of the geometry of their bladder type fuel cell shapes, with an increase in speed, or critical pitch, shifting the level at which it is possible to drop filled bladder type fuel cell to enable a hard landing of an aircraft in an emergency.

At present, a large number of hydraulic structures have been erected on the territory of the Republic of Tatarstan, which are classified as hydrodynamic hazardous facilities. Accidents at these facilities are sources of man-made emergencies. A number of hydraulic structures on the territory have been in operation without reconstruction for more than 70 years. The problem of ensuring the safety of hydraulic structures remains not fully understood and relevant today. Basically all hydraulic structures are located within or above settlements and are objects of increased risk. The consequences of a catastrophic flood can be aggravated by accidents at potentially dangerous facilities falling into its zone. The damage caused by such floods can amount to tens of millions of rubles. Incomplete destruction of the dam, when the safe operation of the structure is no longer possible, can lead to serious economic losses as a result of the cessation of energy production, hydraulic regulation and water collection in the reservoir. Careful monitoring is required in order to identify any possible emergencies. One of the solutions in this situation is the use of various methods for predicting emergency situations at hydraulic structures. In this regard, in the work, the authors have adapted a mathematical model based on Markov chains, which is distinguished by the efficiency of calculations and a high degree of approximation to statistical data. This model makes it possible to predict the state of hydraulic structures when the data on the water level and the volume of infiltration in the hydraulic structure changes. Based on the adapted model, the results of forecasting the water level for real hydraulic structures were obtained.

The article presents proposals on the use of the risk index method to determine the sustainability of cultural heritage sites. This INFORM method is based on the assessment of the three risk components by measuring the relevant indicators in each of three directions: the degree of danger; level of vulnerability; counteraction (overcoming) potential. The method includes about 50 different indicators for measuring hazards and impact on them, vulnerability indicators and determining the necessary resources for stopping hazards. The integral risk index is formed as the geometric mean of the component indices: danger, vulnerability and lack of counteraction potential. The application of the INFORM method for the development and adoption of managerial decisions to increase the sustainability and security of cultural and historical heritage sites makes it possible to assess risk, and in the future, planning measures for the restoration and maintenance of cultural heritage sites.
