The article presents the results of analysis operational parameters piston engine CA 912 ULT which is a propulsion system ultralight gyroplane Tercel produced by Aviation Artur Trendak. Research was conducted under normal operating conditions autogyro and data collected from 15 independent tests including total 14 flight hours during training flights. Engine were recorded at 9 Hz each using on-...

Abstract Noise emissions belong to the crucial design characteristics in modern transmissions. The most efficient way achieve beneficial noise behavior is reduce excitation tooth contact, since contact represents main source of gearboxes. Special flank modifications may optimize behavior, but common approach uses static assumptions, whereas operating conditions include dynamic operation. applic...

Effective electrochemical degradation of carbamazepine (CBZ) in water was accomplished with minimal energy and chemical requirements, showing that Advanced Oxidation Processes (eAOPs) a Boron-Doped Diamond (BDD) anode are promising method for the situ contaminants emerging concern (CECs). The influence several operating parameters (i.e., pH, temperature initial anolyte pollutant concentrations)...

This paper describes experimental and numerical procedures to estimate friction torque on a rotating shaft due to radial elastomeric seals. Two different test rigs have been built, in order to highlight the relationship between the overall friction and the local behaviour of each lip portion in presence of dynamic eccentricities. A direct measurement has been performed with a rotating shaft mac...

Saccharamyces cerevisia known as baker’s yeast is a product used in various food industries. Worldwide economic competition makes it a necessity that industrial processes be operated in optimum conditions, thus maximisation of biomass in production of saccharamyces cerevisia in fedbatch reactors has gained importance. The facts that the dynamic fermentation model must be considered as a constra...
