The Benefits of Integrated Video Management

Building today’s advanced airborne Video Management Systems (VMS) involves the complex and frustrating task of integrating various components that have been sourced from a mix of vendors into a workable solution. A fully integrated VMS provides a better approach that maximizes operator usability and system flexibility while ensuring optimal interoperability. Curtiss-Wright specializes in tailoring exact VMS solutions to meet clients’ platform needs, and has delivered the most reliable and fully-featured VMSs in operation today, including those used by law enforcement agencies across the UK and Europe. Integrated VMSs not only reduce cost and allow for scalability, but also provide a level of flexibility and interoperability that would be unobtainable using components from multiple vendors.

Thinking Outside of the Box: Optimizing System Design With Embedded Expertise

Increasing technical requirements and tighter budgets provide challenges to integrators designing optimal system solutions for SWaP-constrained spaces. Dialoguing with highly knowledgeable COTS vendors early in the design process provides integrators with alternative systems engineering perspectives that result not only in better SWaP-optimized solutions, but reduced cost and schedule times. As a leading COTS vendor, Curtiss-Wright is exposed to a myriad of design problems every day, and has unmatched expertise in properly addressing constraints and providing innovative approaches to any design issue. Allowing our COTS hardware experts to mitigate SWaP-constraints early on in the embedded system design process results in highly-optimized re-architected solutions, and eliminates cost, weight, and schedule penalties.

A New Paradigm for Mid-Lifecycle Design Changes

For decades, the general belief was that the replacement of key components during the mid-lifecycle design refresh of complex electromechanical systems was simply too costly and burdensome — and that any changes in product design would simply need to wait until the next generation.

Expanding GNSS Testing with Multiple Synchronized Signal Recorders

In order to greatly expand recording bandwidth, you can deploy multiple tightly synchronized recorders in the field. Averna studied the example of two RP-5300 recorders (2x50 MHz channels each) that were synchronously inter-connected to form a virtual recorder with total bandwidth of 200 MHz.

Battery Fault Detection with Saturating Transformers

This monitoring system for high-power battery health could be useful for electric cars and the aerospace industry. Lyndon B. Johnson Space Center, Houston, Texas A monitoring network has been created that can be added to a battery consisting of many parallel cells. This network allows the health of individual cells, as measured by the current that they produce under load, to be monitored. If one or more cells are producing less current than the others, the network allows the discrepant cell(s) to be sensed and located.

Digitally Controlled, 12-V Precision Current Source for Extreme-Temperature Operation

NASA’s Jet Propulsion Laboratory, Pasadena, California Many control applications require precision, high-voltage-capable stimulus current drivers for sensor excitation. In particular, a requirement for a stimulus driver that can be primarily integrated into a motor feedback signal conditioning ASIC (application specific integrated circuit) for Martian environments is satisfied by this development.

Scandate Cathode for High-Power, Long-Life Electric Space Propulsion

Applications include electron beam-stimulated lasers for high-power video projection systems and new-generation CT-scan x-ray imaging systems. John H. Glenn Research Center, Cleveland, Ohio Scandate cathodes are able to produce about 20 times the emission of conventional all-tungsten cathodes at the same temperature. Conversely, they operate at about 200 °C lower temperature for the same emission. Scandate cathodes have been studied since at least the 1960s. Between then and 2002, numerous approaches were investigated. All cathodes either did not work or degraded within a few thousand hours. The current nanoparticle approach appears to have overcome previous shortcomings.
