An aircraft wing is actually manufactured by the composite materials with the fibre angled in every ply aligned in multi- direction. Dissimilar thickness of the airfoil and layer directions were almost taken to study the result of bending-torsion. These laminated features are usually designed using the different layers, sequence of stacking, geometrical and mechanical properties. Finite number of layers can be integrated to form many laminates, The wing loading was due to its self-weight and weight of other propulsion systems or due to acceleration due to gravity was deliberated and the deflection over here can be found, this actually studied by aero elasticity. The aircraft wing is severely affected by the loads on along wing direction or vertical direction.NACA 2412 airfoil was taken for designing wing, and it was scaled through a profile with a calculated wingspan to obtain wing model. FLUENT and CFX were used for computational fluid dynamic analysis to determine the lift and drag for wing during zero degreed flaps and angled flaps. By this we intend to show how fast retraction flaps effects the drag and lift of aircraft at cruising speed.

nk 404, shriram surabhi, mallasandra, bayanapalyaThe present article demonstrates the generation of signal based chaos by generating the engineer’s chaos as a product of sinusoids and then wave-shaping them by hyperbolic secant (soliton) or tangent (taliton) functions. The frequency ratio of the input sinusoids serves as the control parameter, and the nature of chaos is studied by observing the iterative map, bifurcation plots and phase portraits. While the phase portraits show interesting and rich patterns, the spectrum shows the new frequency components generated, thanks to the nonlinear wave-shaping.

With the central focus on a broadened perspective of chaos, this article introduces the concept of the engineer’s chaos, characterized by determinism, aperiodicity and sensitive dependence on initial conditions, and exhibiting a marked deviation from conventional chaotic systems by possessing a signal based control parameter. It is seen that multiplying two sinusoidal signals, the simplest possible nonlinear operation generates the engineer’s chaos with the frequency ratio of the two signals acting as the control parameter. The nature of the chaos is observed using iterative map and bifurcation plot. Following this, an application of the engineer’s chaos to dense communications is demonstrated using a proof-of-concept, where the two chaos generating signals are amplitude modulated before multiplying, and transmitted over a channel represented as a Additive White Gaussian Noise of 18dB. The ability to receive and demodulate the signals with reasonable accuracy highlights the capabilities of the engineer’s chaos. The demonstration proves how the engineer’s chaos, the result of a broadened perspective on chaos yields triple advantages of minimalist and simple design, increased information carrying capacity, and security inherent to the sensitivity of chaos.
