ENGeniousMicro proposes to develop a micromachined sensor that will operate at high temperatures with high frequency response to measure surface pressure, shear stress, and heat flux distributions. Through the use of micromachining technologies, we will develop a sensor that has a small form factor and can be flush mounted on the object to be monitored. Our sensor will be designed to have a freq ...

The potential for combustion instability has historically been a hindrance in developing rocket engines, and nearly always represents the major technical risk in engine developments. This proposal addresses innovative approaches toward prediction of liquid rocket engine combustion instability, as well as innovations in full-scale engine stability verification. Specific objectives are to demonstrat ...

Polyacrylonitrile (PAN)/carbon nanotube (CNT) composite fibers will be spun to obtain precursor fiber with about 2 micrometer diameter. By optimizing stabilization and carbonization conditions, high tensile strength carbon fiber will be obtained with a diameter of about 1 micrometer. CNT incoporation can lead to the ordered graphitic structure in the vicinity of CNT, which will improve the mechani ...

We propose the development of a general software infrastructure for simplifying the integration of computer-game software with cognitive modeling tools. The software is designed to meet the requirements of two state-of-art cognitive models, one focused on spatial reasoning, the other on visual imagery. The approach extracts visual scene information from a computer game, represents it in a common ...

Successful completion of the proposed Phase I work outlined and follow-on Phase II work will provide a system to rank existing materials and coatings for severe wear applications. In addition, the ranking system can be utilized to identify desirable properties in new materials and/or coatings that could be developed for specific severe wear applications. The validated system resulting from the Ph ...

ABSTRACT: This proposal is concerned with the development of a novel failure initiation and progressive failure analysis modeling method for advanced composite structures, including the analysis of selected structural joints utilizing a statistically based micromechanics model embedded in a 3D non-linear finite element code. The method accounts for the interaction between out-of-plane failure and ...

Could the future military use of UAV create a revolution in military affairs as great as the introduction of the airplane or the tank? Is the revolution underway now? If so, how can we best prepare our military for success? The advent of Unmanned Aerial Vehicles (UAV) is once more changing present and future aerial warfare. The configuration, deployment, and face of the United States Air Force ...

The objective of this program is to build upon many decades of experience with magnetic flowmeters to develop a next-generation system to measure the burning surface admittance of high-energy-density solid propellants at high frequencies and pressures. Using the results of research on solid propellant rocket motor combustion instability from the past fifty years, one can directly measure the ac ...

For this Phase I program, MO-SCI Corporation and Missouri University of Science and Technology (Missouri S&T) will develop reactive fusion and reactive plasma welding techniques that are capable of joining ultra-high temperature ceramic (UHTC) composites. Past work at Missouri S&T demonstrated the feasibility of fusion welded UHTC composites. This program will build on the joining successes at M ...

Test facilities such as wind tunnels require stringent control of test parameters such as wind speed, temperature, pressure, etc., in order to satisfy the objectives of the simulation. Control of test facilities can be significantly improved using mathematical models for the facility behavior that are developed from physical principles. A shortcoming of mathematical control models is that they t ...
