Abstract For the evaluation of civil aircraft hydraulic system, Fuel Consumption is a very important index. However, there is no effective method to perform analysis for different architecture. This paper proposes that taking fuel weight penalty as a major mathmatical modeling method to analysis traditional architecture and more electric architecture. The result shows that the fuel consumption of more electric architecture is less than traditional architecture.

Hydraulic systems are used in a wide variety of applications, stationary as well as mobile. Hydraulic pumps und motors are in many cases used for both propulsion and various work functions and is thus often a significant user of energy. Efficiency performance of a mobile hydraulic systems over a wide range of pressure and speed conditions is crucially important for power unit to save energy. In this study, efficiency of a mobile hydraulic system are studied. Mobile hydraulic system is equipped with diesel engine as power unit and axial piston pumps used for hydraulic power. The relationships between the efficiency of the axial piston pump and the power loss, the efficiency of diesel engine and the output power were explained by graphics. The average power loss of axial piston pump have changed from 0.1 kW to 2.5 kW. Losses of an axial piston pump have been determined thus fuel consumption and CO2 emission caused by these losses were shown by graph. The CO2 emission affected by the increase in pressure and speed, it reached from 5.231 kg/h to 5.61 kg/h. The research focused on analysis for axial piston pump in mobile applications, with emphasis on pump losses, fuel consumption and CO2 emission.

Annotation Purpose. Assess the prospects for the creation of MTU on the basis of the chassis of the combine and identify potential technical and operational capabilities when used in various agricultural works. Methods. Methods of mathematical modeling and analysis of their estimation are applied in researches of technical and operational indicators of work of MTU. Results. The calculation schemes of completing the units with technological modules are considered, which will allow realizing the potential of the layout scheme of the energy technology means as much as possible. The study of technical and operational indicators of MTU with the use as an energy technology means of the chassis of the combine harvester KZS-9-1 “Slavutych”, which was compared with the performance of MTU on the basis of the tractor T-150K. In the course of researches the calculation of technical and operational indicators of work of MTU at disking, peeling of stubble and cultivation of soil is carried out. Conclusions. Analysis of the results of technical and operational indicators of MTU created on the basis of the chassis of a self-propelled combine harvester in comparison with a tractor of class 30 kN showed that the performance of these MTU with the same agricultural machines will not differ significantly. It should be noted that MTU as a part of energy technology means – the agro processor have worse maneuverability, stability of movement and convenience of aggregation. At the same time increase to 30% of fuel consumption in MTU which are completed on the basis of energy technology means – the agro processor is expected. Keywords: combine harvester chassis, energy technology means – agro processor, MTU, technical-operational indicators.

This work focuses on structural modeling and analysis of aircraft winglet control surfaces. In aerodynamic engineering, reducing drag is an important challenge. To reduce drag a fin device that is placed vertically in the angle set in the wing of the plane. Winglet design reduces fuel consumption by reducing the drag of the aircraft and will make the aircraft more stable during the flight, will also give the aircraft engine more time to reduce the load on the engine thrust life. The goal is to design and simulate a winglet aircraft model using software such as CATIA V5-which is used to build fin models and ANSYS CFX solver is used to test and simulate model fins. With winglets without fins it analyzes change the inclination angles, the results are compared and plotted. Fins are an important part of an aircraft that reduces the amount of drag and fuel consumption by using less energy while reducing wing vortexes.
