The proposed effort aims to deliver a novel process model for carbon-carbon manufacturing to determine thermo-mechanical properties of these materials and their components, thereby enabling a faster cycle for material development for hypersonic platforms. The proposed solution consists of (1) requirement and functionality analyses, (2) a six-level model representing the key steps of the manufactur ...

In Phase I, ISSI will design and demonstrate a laser absorption-based sensor for time-resolved measurements of combustion fuel/product concentrations (H2O, CO, CO2 and fuel) and gas temperature within the detonation channels and nozzle exit-plane of a rotating detonation rocket engine (RDRE). The goal of this STTR is to develop a single sided sensor that plugs into the outer wall of the RDRE simil ...

The research objective of the proposed work is to increase the efficiency of the laser return of a Sodium Guide Star Laser (SGSL) reflected off the sodium layer for increased reliability and applicability of the artificial guide star technique. During Phase I, we will demonstrate the concept of maximizing the SGSL signal returns using numerical simulations that account for the effects of atmospher ...

The Air Force seeks three-dimensional bioprinted tissue that can accurately replicate complex multi-cell function and that can be integrated with biosensors. To address this need, Spectral Energies in collaboration with Prof. Khademhosseini of the University of California, Los Angeles (UCLA) proposes to develop an organ-on-a-chip system. The organ-on-a-chip system will be capable of accurately mod ...

We propose to develop an open, highly scalable, extensible and secure unified logging architecture for performance and cybersecurity monitoring for Naval Control Systems (NCSs). The primary goal of this architecture is to realize a centralized logging infrastructure for monitoring the status of the entire NCS through collecting and aggregating logs from all subsystems. It will be built upon widely ...

Locating objects that vibrate is a way to discern potential threats and locate targets. However, current vibrometry technology typically measures only the global vibration of target and cannot create an extended spatial measurement of the vibration profile of the target. These solutions cannot identify what the target is, nor can they locate potential weak spots on the target, because they lack sp ...

The imaging vibrometer development will be based on a representative Directed Energy (DE) aperture assumed to be 30 cm. This effort will provide both DE and Combat IDentification (CID), modes for relative short range DE operations, and an ISR Combat IDentification (CID) mode for operation at extended range. A combination of analytic derivations and wave optics simulations will be used to define a ...

The development of a catastrophic optical damage model for quantum cascade lasers describing instantaneous laser damage at high optical power levels is proposed. The model will be validated by comparison to experimental data. Based on obtained results, changes to laser design and laser fabrication resulting in an increased damage threshold will be implemented. The work will ultimately result into ...

New, innovative laser spectroscopy technology will be developed for performance quantification and combustion characterization in a Rotational Detonation Rocket Engine (RDRE). The effort will push the state of the art in tunable laser absorption spectroscopy to enable fast time response diagnostics of the extreme pressure and temperature conditions of an RDRE.

Waste heat from Naval diesel generators provides significant opportunity to introduce organic Rankine cycles (ORC) to increase their fuel efficiency. The objective of the proposed effort is to design and demonstrate a high-speed, spinning scroll expander (HiSSSE) ORC as a power dense waste heat recovery system for diesel generators on ships. The system will leverage Air Squared’s spinning scroll ...
