COMPUTATIONAL STUDY OF AERODYNAMIC CHARACTERISTICS OF SINGLE-ROTOR HELICOPTER TAIL ROTOR UNDER THE INFLUENCE OF VORTICAL WAKE OF MAIN ROTOR AT THE HOVER WITH CROSSWIND

For single-rotor helicopters there are special flight modes, when tail rotor (TR) is under significant inductive influence of vortical wake of main rotor (MR).Inductive influence of vortical wake of MR can provoke essential changes in flowing of TR and its aerodynamic characteristics comparing to isolated rotor.In this case increase of tail rotor p

In the paper approximate formulas for the mean waiting times and the buffer dimensioning in the system with vacations fed by the stream of Poissonian type with constant service times is shown.Furthermore, in the considered system the time intervals of the availability/notavailability of Gouging Torch Replacement Parts the service are constant and a

Globally, an estimated 107 million people have an alcohol use disorder (AUD) leading to 2.8 million premature deaths each year.Tuberculosis (TB) is one of the leading causes of power cable death globally and over 8% of global TB cases are estimated to be attributable to AUD.Social determinants of health such as poverty and undernutrition are often

We present a case of composite oromandibular reconstruction with fibula free flap in which the vascularity to the flap was established in a retrograde direction through the distal end of the peroneal pedicle vessels.The flap was initially designed in 7.40 such a way so as to anastomose with superior thyroid artery.However after initial good flow, t

Winning business models increasingly build on stronger integration of clients in the world of production.Empirical evidence on such prosuming for Files the wine industry is lacking.A multidimensional approach and 321 interviews with wine consumers allowed to explore presuming interest with descriptive, correlation, and a two-step cluster analyses.T
