A Novel Method for Constructing Grid Multi-Wing Butterfly Chaotic Attractors via Nonlinear Coupling Control
Published 2016-01-01“…And a piecewise linear function, which is taken into the linear coupling controller, is designed to form a nonlinear coupling controller; thus a five-dimensional chaotic system is produced, which is able to generate gird multi-wing butterfly chaotic attractors. Through the analysis of the equilibrium points, Lyapunov exponent spectrums, bifurcation diagrams, and Poincaré mapping in this system, the chaotic characteristic of the system is verified. …”

GAYA ANGKAT DAN GAYA HAMBAT SAYAP PUNA MODEL NACA 0015 MENGGUNAKAN SIMULASI ANSYS FLUENT
Published 2024-12-01“…The simulation uses Ansys Fluent to determine the aerodynamic characteristics, after varying the angle of attack at a predetermined speed on an airplane (unmanned aerial vehicle) wing with a NACA 0015 airfoil. The results of the research that has been carried out are the maximum angle of attack at a predetermined speed variation (Re = 0.2 x 105 to 1.0 x 105), namely 25° at each angle of attack, with details of a speed of 50 m/s getting the highest lifting force, around 38,72 N and drag force in the area 6,49 N.…”
