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 My Dog (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

Lane-changing (LC) is a critical task for autonomous driving, especially in complex dynamic environments.Numerous automatic LC algorithms have been proposed.This topic, however, has not been sufficiently addressed in existing on-road manoeuvre decision methods.Therefore, this paper presents a novel LC decision (LCD) model that gives autonomous vehi

This study was conducted to know the effect of adding plants, ginger and black bean and garlic to feed on some production traits and egg production of Japanese quail during 49 days of age.Chicks were divided into four treatments of the first control -free plant additions and second treatment is add ginger and third treatment is add black bean and g

Abstract For photoautotrophic plants, light-dependent photosynthesis plays an important role in organismal growth and development.Under light, Arabidopsis hypocotyl growth is promoted by the phytohormone ethylene.Despite well-characterized ethylene signaling pathways, the functions of light in the hormone-inducible growth response still remain elus

The objective is to define the place of the operation of simple closure for perforated duodenal ulcers in the modern stage of the treatment of these patients.Material and methods.Comparative analysis of 2 groups of patients with perforated duodenal ulcer was made.The 1st group consisted of 40 patients who performed simple closure of perforated ulce
