“Liquid Cooled Engine Power Plants for Transport Aircraft”

When creating modifications of transport category airplanes, fuel efficiency appears in the structure of their parameters.This indicator is very important, since operating costs largely depend on the amount of fuel consumed per unit of work.The problem of evaluating the fuel efficiency of modifications of transport aircraft with multi-engine power plants is considered. It is noted that multi-engine power plants, used mainly on medium and heavy aircraft, contribute to solving a number of problematic issues:– expanding the ability to operate in hot climates and highlands;– improving operational safety in the event of failure of one or two engines in case of deterioration of take-off/landing conditions, runway conditions, icing conditions and other emergency situations requiring increased thrust-to-weight ratio;– expanding the network of airfields used by reducing the sites of continued or interrupted take-off;– the absence of the need to use on the created modification more powerful engines, domestic or foreign, which do not have forced (emergency) operating modes.– However, the use of forced-mode engines in such power plants leads to a deterioration in fuel efficiency of up to 20 percent.For the preliminary design stage of modifications, a model is proposed for the formation of a fuel efficiency parameter while simultaneously replacing the main engines and changes in the wing geometry, which allows reducing fuel consumption for the flight, and thereby compensating for its losses when using emergency modes.This approach was implemented in the process of development of the An-188 operational tactical military transport aircraft, in which the replacement of 4 theater with 4 turbojet engines was coordinated with the necessary changes in the wing geometry, which allowed the military-technical complex to ensure fuel consumption in horizontal flight mode with maximum payload 154 g/t∙km per unit of useful work, i.e., lower than that of competitors-analogues.

Power plants as electricity producers need to be maintained using monitoring performance and continuous improvements. Company management of power plant is difficult to make a decision for the continuous improvement, requires Performance Measurement Tools (PMT) to determine the performance of a gas engine power plant. PMT developed using Key Performance Indicator (KPI) that was defined through Forum Group Discussion (FGD) with different field of expertise in company and based on references and the weighting of KPI criterion that was developed by Analytic Hierarchy Process (AHP). This study has developed the weight of KPI that the weight of each criterion which will be used as a reference is Rank 1 – Power Output (MW) – PO (70.81%), Rank 2 – Heat Rate (Btu/kWh) – HR (14.91%), Operating Ratio (%) – OR (8.06%) and Rank 4 – Capacity Factor (%) – CF (6.22%).

Currently, the topic of research of the aircraft noise influence on the environment is relevant. Aircraft and engine developers are constantly exploring ways to reduce noise following the new standards of the ICAO Committee (CAEP), whose main task is to protect the environment from the effects of aviation, to provide a comfortable environment for people exposed to aircraft noise and harmful substances. By limiting the permissible noise level of aircraft, CAEP initiates aircraft manufacturers to introduce the latest noise reduction technologies in their design. Measurement of aircraft noise is obviously an important type of research not only in the aircraft industry. The existing airports in the course of reconstruction, and new ones at the project development stage, should be mandatory tested on indicators of aircraft noise, which will penetrate into the surrounding area, including settlements of various sizes. Currently, scientists from different countries are making significant efforts to reduce the turbine noise of existing and prospective civil aircraft. Of course, nowadays, external jamming methods are commonly used. At the same time, an important way to reduce engine noise was the widespread use of so-called sound-absorbing structures. This article describes the direction of reducing the level of aircraft noise at the source and on the ground, near airports. To reduce the noise in the source of noise, the ways to reduce the turbulence of the streamlined aerodynamic bearing surfaces are considered by reducing their inductive resistance and matching the flow of gas in power plants. It is shown that the implementation of such approaches in modifications of domestic passenger and transport aircraft gives a positive result. When solving the problem of reducing noise on the ground, the study analyzed the effect of aviation noise on the population living near the airport as an example. The necessity of using soundproofing means in residential areas to reduce noise exposure is shown. An analysis of the effects of noise exposure is given. In conclusion, the preliminary results obtained in the course of research are presented.
