The primary objective of this Phase-II research effort will be to build, deliver, and test a next-generation time-domain ballistic photon imaging (BPI) system based on ultrafast lasers for characterizing the two-phase combustion region within bi-propellant rocket engines. This will include integration into a rocket facility of choice for the Air Force Office of Scientific Research and the Air For ...

There is an increasing demand for high temperature sensors that operate accurately and reliably in extreme environments and they are vital in several aerospace applications. This aim was directly addressed by a novel idea where microstructural changes caused by phase transformation and the attendant physical property changes that can be easily measured is used as a sensor. In Phase I of this progr ...

All the promising Mo-Si-B-X alloys developed so far contain a mixture of Mo-solid solution and brittle intermetallic phases. For further advances to occur, a full understanding and control of the properties of the Mo-rich solid solution is critical. The poor low temperature ductility of the solid solution phase and the catastrophic intermediate temperature oxidation resistance continue to be key ...

The objective of this proposal is to develop and validate a methodology for obtaining accurate, reliable and transferable force fields for a variety of ionic liquids (ILs) including those designed for lubrication, gas generation, energy storage and as energetic materials. The methodology involves development of a hierarchy of force fields through reduction of degrees of freedom in a statistical me ...

We propose to develop a framework for linking cognitive models with virtual environment simulations of the sort that are typically used in military training applications. The framework will be designed to accommodate a variety of different cognitive models and simulations. It will supply a cognitive model with sensory information obtained from a simulation, and enact cognitive model motor and othe ...

Field-emission electron-emitting arrays hold promise for use in high current-density electron-beam devices as replacement for power consuming thermionic emitters. Large field-emitter arrays, however, are limited in total current due to non-uniformity and resulting instability problems. As a solution to these problems current-limiting devices, such as a field-effect transistor (FET) for each emitte ...

This STTR Phase I project is designed to develop a novel process for fabricating a nano-grained ceramic material for infrared windows. The proposed STTR builds upon our previous Phase I (Navy) SBIR experience to minimize risks and maximize the likelihood of success. This proposed work will utilize an innovative method to fabricate nanocrystalline alumina infrared window materials with significantl ...

In this STTR project, an efficient and high-fidelity computational module to predict non-gray radiative transfer will be developed and validated. The proposed hybrid approach to solve the radiative transport equation (RTE) is a combination of the spherical harmonics (PN) method and the Monte-Carlo method. Non-gray gases will be treated using the full spectrum correlated k-distribution (FSCK) metho ...

Given the vulnerability of the GPS system to intentional or hostile denial of service, it is imperative that the U.S. military develop technologies that provide robust navigation solutions that do not rely on GPS data. To achieve this capability, Aurora and MIT have teamed to develop the Integrated Visual and Inertial Sensor Information Onboard Navigation (I-VISION) system, which will couple optic ...

This STTR Phase II project is directed towards the development of high performance large-area thick YBCO films and microwave devices on suitable single crystal substrates through modified TFA-MOD approach for transmit and receive applications. We propose to continue our successful Phase I project to further increase critical current density of Jc to 3-5 MA/cm2 and lead to state-of-the-art IMD (int ...
