Aircraft Design and Development: An Overview
Abstract: This paper addresses issues related to airworthiness standards, air loads criticality, handling qualities requirements, and flight testing from the personal experiences of the author. Current control technology has significant impact on airworthiness specification description. Combination of air loads cases needs judicial selection along with control criteria. Control software can be synthesized in real time for required handling criteria. Concurrent aeroelasticity needs consideration for optimum aerodynamic design features that is highlighted …

Effect of Damage on the Modal Parameters of Composite Plates
Abstract: Normal 0 false false false EN-IN X-NONE X-NONE In the present work, the effect of delaminations on the natural frequencies and mode shapes of composite panels has been analyzed, both experimentally and by finite element technique. Bi-woven glass cloth with epoxy resin as matrix is made use of to prepare the laminate. Vacuum-bagging method was employed in the fabrication of specimens. Specimens were prepared with 3 mm thickness and tested …

Handling Qualities-Fighter Aircraft
Abstract: Aircraft handling qualities quantify the extent to which the pilot can control the aircraft and accomplish the task with ease or difficulty. Stick force gradient, recovery rates from maneuvers, layout of controls, case of control operations, and mission accomplishment form the part of hqs. Current equivalent systems of flight control of fly-by-wire aircraftwith statically unstable airframe aim at meeting maneuver demands and provide required hqs. The hqs criteria are addressed …

Comparison of Control Strategies using Soft Computing Techniques for Shunt Active Power Filters in Aircraft Power Utility of 400 Hz
Abstract: Three different control strategies for extracting reference currents for shunt active power filters optimized using adaptive tabu search and genetic algorithm have been compared and their performance has been evaluated under different load conditions. The compensation ability of different control strategies will be compared and suggestion will be given for optimum strategy to be used under different loads. Simulation results using MATLAB have been included.Keywords: Active power filter (APF), constant …
