Novel low pressure process for aviation turbine fuel production through hydrotreating route(Abstract)Aviation Turbine Fuel (ATF) demand is expected to increase rapidly in the wake of major developments in aviation industry and growing popularity of air travel. In this scenario, refiners producing ...
Low-Pressure Screw Air End Drive Chain · The high-efficient driving motor directly connected to the two-stage compression air end without coupling, the transmission chain is maintenance-free, reducing energy consumption by 1%; · IP55 fully closed motor and air end housing integrated, effectively ...
The issue is not related to Rolls’ ongoing program to address high-pressure turbine blade durability issues that have plagued much of the Trent 1000-powered 787 fleet for several years.
In the present study, a multi-nozzle hydrogen burner based on the micromix combustion principle (MCP) and designed to operate under atmospheric pressure and without preheated air was investigated both numerically and experimentally. Previous investigations regarding this type of burner have shown low NO...
The gas turbine, especially an aviation engine, has at least one oscillatory element (16) positioned in the region of the exhaust duct (10) from the low pressure turbine. The oscillatory element is excitable into oscillations in such a way that noise which is radiated from especially the low...
Hypoxia ranges typically refer to the levels of oxygen in the blood, which are measured using parameters such as partial pressure of oxygen (PaO2) or oxygen saturation (SpO2). Based on the severity of oxygen deprivation in the blood, hypoxia can be classified into these ranges: mild, moderate...
The WE43 alloy used in this paper was melted in a vacuum smelting furnace, followed by low-pressure sand casting. The American Society of Testing Materials (ASTM) standard gives the composition range of WE43 magnesium alloy as follows: Neodymium 2.0∼2.5 wt.%, Yttrium 3.7∼4.3 wt.%, Ra...
the region that generates crossflow. Crossflow is produced by any chordwise pressure gradient. There is always severe acceleration over the forward part of the wing, and narrowing the region of acceleration will reduce crossflow. This leads to a pressure distribution with steep gradient at the ...
The EHPS includes solar photovoltaic panels (PV), wind turbines (WT), electrolyzers, battery energy storage systems (BESS), hydrogen compressors, and high-pressure tanks for hydrogen storage (Fig.1). Two EHPS configurations are modeled: (i) when the EHPS is mainly powered by renewable resources...
