MECHANICAL AND MICROSTRUCTURAL CHANGES IN EXPANSIVE SOILS TREATED WITH LIME AND LIGNIN FIBER FROM PAPER INDUSTRY

Mechanical and Microstructural Changes in Expansive Soils Treated with Lime and Lignin Fiber from Paper Industry

Expansive soil exhibits significant swellings and shrinkages, which may result in severe damage or the collapse of structures built upon it.Calcium-based admixtures, such as lime, are commonly used to improve this problematic soil.However, traditional chemical additions can increase significant environmental stress.This paper proposes a sustainable

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 Bridle and breastplate. and its aerodynamic characteristics comparing to isolated rotor.In this case
