Environmental degradation of aerospace turbine components is a major concern for aircraft and power generation systems, and various surface treatments are utilized to extend the lifetimes of these critical components. This Phase II project is targeted toward extending the durability of thermal barrier coatings (TBCs) on hot section turbine components. TBCs are highly susceptible to degradation b ...

Close-coupled fuel injector/flameholders used in modern augmentors face difficult challenges in static stability due to higher airflow velocities and higher levels of vitiation than past augmentors. In addition, close-coupled fuel injection schemes typically employ jet-in-crossflow methods to adequately penetrate and mix the fuel with the mainstream, but have difficulty providing sufficient fuel ...

The following task is to be executed under work in support of NAVAIR and Office of the Secretary Defense (OSD). These tasks are in support of further research and development of hearing protector devices, communication subsystems, and hardware assemblies that are capable of improving noise attenuation and communication functions for personnel working with the target platforms. The research, devel ...

One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of EMI and the goal of RF system designers and analysts is to achieve EMC where no interference problems exist. We propose to develop a software tool named Electromagnetic Interference Toolki ...

Modern aircraft include numerous RF systems and associated antennas of diverse types. The designed performance of antennas is typically degraded by their installation on the airframe. Also, the presence of many RF systems in a small region creates enormous opportunity for undesired interference via antenna-to-antenna coupling. These conditions present serious challenges for engineers tasked with i ...

This program is intended to advance the state-of-the-art d36 shear mode projector. Phase I of this effort produced a projector which demonstrates promising bandwidth and source level, especially considering its compact size. It is also the first known d36 underwater projector in the history of piezoelectrics. To develop a robust, high power, and broad bandwidth d36 shear mode projector array and b ...

The objective in this exploratory development is to design, fabricate and test a dual-mode radome for a high speed missile application. Performance, cost and ease of manufacturing will be emphasized. Radome models will be produced to be as close toflight hardware as practical. The use of an insert to provide performance enhancements will be incorporated into the design.

The objective of this Phase II program is to achieve a commercial solar blind AlxGa1-xN based p-i-n ultraviolet (UV) photodetector product, with high solar blindness, high external quantum efficiency and low dark currents. The Phase II work will buildupon the results obtained from the completed Phase I project, which showed the feasibility of the proposed lateral epitaxial overgrowth approach to ...

The United States Navy (USN) uses a number of high strength steels, primarily AerMet100, in demanding landing gear structural applications. Unfortunately AerMet100 is expensive and, despite impressive mechanical properties, is subject to stress corrosion cracking (SCC) and requires plating operations for corrosion resistance. In a recently completed Phase I SBIR program QuesTek Innovations applied ...
