The occurrence of combustion instability has long been a matter of serious concern in the development of liquid-propellant rocket engines due to the high rate of energy release in a confined volume in which energy losses are relatively small. Positive feedback between the acoustic waves and unsteady combustion could lead to the destruction of an engine in a fraction of a second. The situation is ...

The United States Missile Defense Agency (MDA) is searching for a software-defined multi-channel radar receiver that would provide improved performance and added flexibility over currently deployed radar systems. In response, MaXentric is proposing a system codenamed MASR (Manycore Adaptive Software Radar). The MASR system is composed of a hierarchy of X-band front-ends, high-speed digitizers, F ...

The objective of this Phase I proposal is to demonstrate, through a rigorous design and modeling, the feasibility of a single chip Transmit/Receive Integrated Circuits (TRIC) with on-chip controller and compensation networks for next generation X-band radar systems. TRIC will include RF, analog and digital circuits on a single chip. TRIC functionality would include Frequency-modulated Continuous ...

Higher efficiency solar cells are needed to reduce mass, volume, and cost of DoD space missions. However, to achieve higher efficiency and radiation hardness of the best to date multi-junction photovoltaic (PV) devices, several challenges must be addressed. This project aims to develop: 1) Quantum Well (QW)-based multi-junction cell that exhibits enhanced efficiency, and 2) Radiation-hardened PV c ...

High power microwave (HPM) sources have been developed over the past few decades for many important DoD missions ranging from electronic warfare to intentional EMI to impulse radar. In this proposal, we describe an integrated program that seeks to develop innovative solutions based on mesoband source and antenna technology to improve the effectiveness of HPM-based BMD systems. Our research will ...

Hypersonic missile defense systems are being designed to reach global threats. During flight, external surfaces are predicted to reach temperatures in excess of 2200C. As a result, innovative, high performance thermal protection systems (TPS) are of great demand. Among ultra-high temperature ceramics (UHTC), it is well known that ZrB2- and HfB2-based materials have high melting temperatures and ...

The leakage of electromagnetic (EM) energy into air vehicles, and particularly into ordnance, poses a hazard that requires careful evaluation. Under current guidelines, such evaluations are primarily to be carried out through extensive testing of items under possible field conditions, a process that can be both time-consuming and costly. The scope of this STTR Phase I activity is to implement a h ...

Military operations in urban areas have increasingly become a key capability for our armed forces. The increased risk of use of the unique nature of large urban environments by hostile forces to their tactical advantage, and related civilian casualties, requires updated procedures, comprehensive training, and constantly evolving capabilities. Current training technologies fail to address the signi ...

A need exists for polarization interrogating and discriminating Ladar systems to detect and discriminate defilade targets. In the proposed effort, Aerius, and our partner at the University of Illinois, will apply photonic crystal technology to extend Aerius’ high power, high wall plug efficiency, Vertical-Cavity Surface-Emitting Laser (VCSEL) results to develop a stable polarization switched VC ...

Toyon Research Corporation and Brown University propose to develop a complete real-time software solution which ingests multi-sensor ISR imagery and produces geo-specific, realistic simulated imagery for flight simulators and training devices. The technical innovations enabling this solution include fully automated 3-d model construction from sequences of ISR video frames, and geo-registration of ...
