An investigation of canted adjustable endplates for the control of drag
(Wichita State University, 1954-04)Wind tunnel tests were conducted on a model wing with a Clark Y airfoil section. The wing, which had an aspect ratio of 5 with no taper, was made with a full span leading edge slot and a 30% chord slotted flap. Wing tip ... -
Viscoelastic relaxation in bolted thermoplastic composite joints
(Wichita State University, 1991-12)Results from a research program to investigate the long term effects of through-the-thickness fastener clamp-up force (preload) relaxation on the strength of mechanically fastened joints for two graphite/thermoplastic composite ... -
Effect of flaperons on a biplane configuration
(Wichita State University, 1994-05)The use of full span flaperons on low speed biplane configurations i~ a unique synergistic concept that has yet to be evaluated. The well-executed biplane configuration is useful for performing low speed aerobatics, ... -
Analytical modeling of metallic honeycomb for energy absorption and validation with FEA
(2005-05)Honeycomb materials possess high energy absorption characteristics and are useful for the impact protection of structural members. Various honeycomb configurations are being developed for a variety of applications. Analytical ... -
Direction of arrival angle estimation schemes for wireless communication systems
(2005-05)In array signal processing, estimation of the direction of arrival angle (DOA) from multiple sources plays an important role in the array processing area, because both the base and mobile stations can employ multiple antenna ... -
Operational tolerance allocation and machine assignment under process capability and product value constraints
(2005-05)Process planning is an activity within the production process that translates design requirements into a detailed description of instructions for transforming a raw stock of material into a completed product. The instructions ... -
Finite element analysis of vertebral end-plate failure under high dynamic axial load and its relation to age
(2005-07)This research was aimed to develop the analytical model of functional spinal unit with the intent of understanding the contribution of Intervertebral disc condition on the failure mechanism of End-plates under high rate ... -
Reduced static lateral stability in airplanes
(2005-12)Recent flight test experience and simulator studies have shown that the traditional test for static lateral stability, the steady heading sideslip, in some cases may be overly conservative and place unnecessary restrictions ... -
Distributed detection and data fusion in resource constrained wireless sensor networks
(2005-12)Wireless sensor networks have received immense attention in recent years due to their possible applications in various fields like battery-field surveillance, disaster recovery etc. Since these networks are mostly ... -
Voltage control with shunt capacitance on radial distribution line with high R/X factor
(2005-12)As a previous study showed, the voltage on a distribution line with high R/X ratio will actually decrease as shunt capacitance is added. This thesis develops a new distribution feeder model and confirms this unexpected ... -
Predicting recloser failure rates from field condition assessment
(2005-12)This research develops a technique to predict the failure rate of a power distribution system recloser. The prediction is based on suggested criterion given and defined within this paper. Because inspection practices differ ... -
Online aerodynamic parameter estimation for a fault tolerant flight control system
(2005-12)Wichita State University (WSU) and Raytheon Aircraft Company are working toward the development of a flight control system to reduce the workload for a pilot under normal as well as deteriorated flight conditions. An ’easy ... -
Electric transmission line routing using a decision landscape based methodology
(2005-12)Transmission line construction is one of the most complex engineering projects. Routing a transmission line is much more difficult than routing any other public infrastructure. The present system used by utilities is time ... -
Statistical approach for predicting remaining life of crosslinked polyethylene insulated cables
(2005-12)This study focuses on developing new remaining life model of the Cross linked polyethylene (XLPE) insulated medium voltage cables that are in use for hot and dry climate. Cross linked polyethylene insulating material ... -
Distributed source coding using non binary LDPC
(2005-12)In this thesis we have extended non binary low-density parity-check (LDPC) codes, developed for channel coding, to be used for source coding to compress correlated non binary sources. Focusing on the asymmetric case of ... -
Ice particle trajectory simulation
(Wichita State University, 2005-12)Large ice particles shed from an airframe can cause damage to downstream aerodynamic surfaces and aft mounted engines. A simulation tool was developed to compute the trajectories of shed ice particles and determine the ... -
Mechanical testing and evaluation of high-speed and low-speed friction stir welds
(2005-12)The potential of the Friction Stir Welding (FSW) process is easily observed in the creation of defect free welds in almost all of the Aluminum alloys. The success and applicability of the process, however, will depend on ... -
Incorporating environmental index as waste into value stream mapping
(2005-12)In today’s fiercely competitive environment, the goal of any enterprise is to make money now and in the future (Goldratt, 1992). In order to fulfill this goal, an enterprise should eliminate waste embedded in the value ... -
