The increased use of reusable systems continues to be one of the most promising options for creating advancements in the daily maintenance of rocket systems, lowering hours for preparation and diminishing expenses for preparation. However, since the end of the DC-X/XA Delta Clipper program, flight testing of candidate reusable launch vehicle (RLV) designs, technologies and operations has come to ...

Modern military aircraft carry many microwave and RF systems which must operate in close proximity to one another. Radio frequency interference (RFI) is virtually inevitable. The EA-6B Prowler electronic warfare (EW) aircraft presents a particularly severe interoperability problem because its primary mission is to jam enemy radars. Specifically, the performance of life-critical identification, fri ...

Progress has been made in developing high fidelity rotorcraft simulation models in order to adequately predict rotorcraft performance, stability, and loads in support of design, operation, and flight testing. Limitations, however, exist in several essential aspects of modeling rotor aerodynamics including blade stall, rotor tip effects, rotor downwash, rotor/airframe interference, and rotor ...

In order to provide for more reliable discrimination of RVs and decoys, MARK Resources proposes to develop algorithms to extract micro-Doppler information from Aegis BMD S-band radar returns. A new signal processing technology that goes beyond analyzing either imagery or time-frequency distributions, exploiting the complex signal to extract very accurate measurements on individual features that a ...

As described in Navy SBIR Solicitation N05-096, there exists today a strong need for advanced preforming approaches to produce complex-shaped CMC cooled-turbine components for military engines. MATECH/GSM proposes to address this need by employing innovative low-cost preforming approaches using ""Net-to-Shape""TM non-woven architectures for those CMC components that require high structural perform ...

MATECH GSM proposes to develop a low cost, uniform, reproducible Si-doped BN interface coating process for 3-D and 2-D woven ceramic fiber preforms. Using MATECH's new Reactive Transformation Process (RTP), Si-doped BN interface coatings will be demonstrated on woven SiC ceramic fiber performs without fiber-to-fiber bonding. Key parameters to be investigated will include: 1) Control of interface ...

The use of ceramic matrix composites (CMCs) has the potential to increase the life and operating envelope of turbine engines. While great strides have been made in mechanical properties, CMCs still suffer from limitations in terms of shape capability, especially with complex-shaped parts such as turbine blades. Using high-strength fibers that have been woven into a fabric causes problems due to th ...

Safety and reliability of ordnance, such as that in solid rocket motors, requires determination of system integrity. To achieve this, a need exists for embedded sensors to provide real-time high-speed indication of system health. Optical Fiber Bragg Grating (FBG) sensors are the most promising types of sensors for dynamic strain measurements due to their light weight, small size, immunity to elect ...
