The Phase I deliverable will be a physic-based model which represents a CMC gas turbine component concomitantly at the material level and the structural level. This model will be probabilistically analyzed to account for the uncertainties in material properties and the uncertainties in the size and impact velocities of possible foreign objects (FOD). A ceramic material must display sufficient capa ...

Resource virtualization concepts are in heavy commercial use for optimizing the performance of distributed applications. Resource virtualization allows resources to be allocated and adapted on-the-fly, and enables a wide range of distributed computing, networking, and sensing applications. However, resource virtualization has traditionally been developed for fixed, stable networks, and cannot adeq ...

The objective of this project is to develop a methodology for predicting reaction violence of full-scale munitions in either a fast or slow cook-off scenario. This methodology will use a combination of existing heat transfer models and thermal stimulus simulation tools coupled with an empirical model to be developed from data collected from various lab and subscale experimental hardware. Hardware ...

This proposal is being submitted in response to the solicitation topic N10A-T002 (Development of a Computational Method for Prediction of After Burning Effect) by BUSA Engineering Consulting (Dr. Jianghui Chao) in collaboration with University of Florida (PI: Prof. S. Balachandar). The overall objective of the proposed effort is to contribute to national defense and security by advancing the state ...

Northwest UAV Propulsion Systems proposes using our purpose built heavy fuel engine designed and built in the USA for small unmanned aerial systems in the tier 2 & 3 class. We will be adding a lightweight ceramic material set combined with FEA (Finite Element Analysis) and heavy fuel atomizer (IRAD Project) to create a lightweight engine for a SUAS or STUAS class UAVs. The Ceramic material set is ...

The objective of this proposed Small Business Technology Transfer (STTR) effort is to develop an experimentally-validated, highly detailed chemical kinetic reference model of surface chemistry for C-SiC-SiO2 rubber composite materials exposed to high temperature, high pressure, oxidizing environments. This reference model will then be reduced into simplified reduced-order models that could be easi ...

A unique type of air lubricated thrust bearing called a Wave Bearing is proposed to assist a rolling element bearing to carry the thrust load and to improve the bearing’s life when used in a micro gas turbine engine. The Wave Bearing technology will provide improved reliability, safety and life compared to rolling element bearings used alone, as well as to allow simplification of engine design a ...

different modes, while using different combinations of subsystems. This presents a challenge for the personnel validating the system during design and development; the number of combinations of environments, modes, and subsystems is exponential. They cannot all be tested, so an optimal subset of tests must be run. We propose to develop VERITAS: Validation and Evaluation of Remote, Interactive Tea ...

The dependability, persistence, and versatility of unmanned systems have made them indispensable assets in today’s warfighting. As they are tasked to fulfill new missions in unpredictable, dynamic environments, they are transitioning from remote control into the realm of autonomy. Here they perform rapid and semi-autonomous behaviors, such as re-planning and re-tasking, to accomplish mission obj ...

Military shelters currently use electrically driven Environmental Control Units (ECUs) to provide cooling for the air inside the shelter. The ECU is vapor compression cycle powered by a diesel generator, operating on JP-8 fuel. Other than fueling jet engines, the largest drain on U.S. military fuel supplies in current operations comes from running generators at forward operating bases. In hot cli ...
