Performance Evaluation of Neural Network and Conventional Control Techniques Based Shunt Active Power Filter for Constant Frequency Aircraft Power System
Abstract: Synchronous reference frame strategy for extracting reference currents for shunt active power filters have been modified using artificial neural network and its performances have been compared. The acute analysis of comparison of the compensation capability based on THD and speed will be done, and recommendations will be given for the choice of technique to be used. The simulated results using MATLAB model are shown, and they will undoubtedly prove the …

Perturbative BIS Strings and Superstrings Hindering to the Space Dynamics
Abstract: String theory helps us to describe theoretically the ultramicroscopic properties of the space. It makes the GTR given by Einstein fully compatible with the laws of quantum mechanics. String theory states that the elementary components of the universe are not point particles. Rather they are tiny, one-dimensional slender thread-like object or fibre like rubber bands. Despite being composed of molecules and atoms, these strings are inextricably bound up with the …

Rib Flange Bending Methods
Abstract: Weight of aircraft structures plays a vital role in enhancing the business revenues of the manufacturers and end customers. Thus, the aircraft designers and manufacturers attempt to produce structures that are optimized for weight, cost, and at the same time serves the structural integrity, performance and safety requirements as specified by the certification agencies. One way to approach the problem of excess weight is to figure out the innovative analysis …

Design and Structural Analysis of Bracket for Control Unit in Light Combat Aircraft
Abstract: Every aircraft essentially consists of an environmental control system (ECS) which is very much required to control the interior environment for the flight crew and the equipment. The charged air (compressed air) from the seventh stage of compressor unit of engine is tapped used for cooling the cockpit and avionic system. The charged air is made to pass through the various components of the ECS such as pre-cooler, primary heat …

Effect of Flexibility on Aircraft Wing
Abstract: The shape of the aerofoil determines how the air circulates around it and how much moment and force will be the acting on it. When the body is rigid (fixed) flow around the geometry remains unchanged at particular A.O.A. (angle of attack), but if the body is allowed to be flexible (free) i.e., it can deform its shape, due to which there will be a significant change in the shape …

Stress Concentration Factors for Stiffener Run-Out Regions
Abstract: Stiffener and stringer run-out is a common design feature followed in aircraft structures such as fuselage, wings and empennage. The run-outs are necessary due to specific structural and interface requirements. These run-outs act as a stress raisers similar to any geometric discontinuity in these structures. The stress concentration factors (SCFs) are available only for stiffener with 90 º run-outs (also known as shoulder fillets) in the literature. In the absence …
