A method of analysis for deriving a single propeller by means of multiple engines remotely located
(Wichita State University, 1948-05)An investigation of a dual engine drive to one propeller is presented. Two engines, one on each side of a common gear box and separated from it by clutch assemblies, provide the energy for the extension shaft. This shaft ... -
Research investigation of boundary layer control by blowing on the N.A.C.A. 23012 and 23015 airfoil sections with various flaps
(Wichita State University, 1950-05) -
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 ... -
Generalized gas turbine engine performance
(Wichita State University, 1969-05)This thesis develops methods of generalizing the performance of specific engine components for use in a generalized gas turbine engine performance computer program. This method produces inexpensive engine performance ... -
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, ... -
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 ... -
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 ... -
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 ... -
Service differentiation via cooperative MAC protocol (SD-MAC)
(2005-12)With the recent advances in wireless communications and networking area, it has been a great challenge for researchers to improve a medium access protocol for providing an efficient service differentiation in wireless ad ... -
Information theoretic analysis of the capacity of multi channel digital image watermarking
(2005-12)Watermarking channel capacity is defined as the highest rate in bits per image of information that can be embedded with arbitrarily low probability of detection error under a given distortion between original and watermarked ... -
Propeller performance measurement for low Reynolds number unmanned aerial vehicle applications
(2005-12)The recent increase in the development of UAV’s and MAV’s has created a strong demand for small propeller performance data. Propeller performance is critical to the success of these aircraft and guaranteed performance ... -
Analysis of 3+2 point seat belt configuration and occupant responses in rollover crash of a pick-up truck
