Basic Elements of MIL-STD-704

December 3, 2014

Electronic systems designed for operation in a U.S. DoD aircraft must comply with MIL-STD-704, which defines certain parameters and characteristics the electric power in an aircraft must meet. To demonstrate compliance, these systems must pass comprehensive acceptance testing, measuring responses to a large set of events and conditions, including voltage transients, over- and under-frequency, over- and under-voltage and power transfer operations.

This white paper is not a primer on designing for MIL-STD-704 compliance but simply a high-level summary of what is covered by the standard, a first step in understanding its requirements.  The white paper supplies a summary of the standard and presents some ideas regarding ways to achieve compliant designs.

OpenVPX Chassis Thermal Management: Dangerous Myths and Analytical Tools

December 3, 2014

The Defense and Aerospace rugged systems market demands a wide range of computing capabilities at extreme environmental conditions. Across the board, applications need more processing power and, inevitably, thermal management becomes more challenging as the amount of processing power grows.

The increase in thermal management challenges is also tied to the industry shift from VME implementations to OpenVPX. These new OpenVPX systems can be configured with an array of new processing elements, driving huge performance leaps relative to the VME system of just a few years ago. However, that new performance level brings with it a new design challenge – managing the equally huge leap in power use manifested as heat.

Certain myths and misconceptions can further complicate the issue for systems designers, while analytic tools exist to help efficiently address thermal management designs.   This white paper examines both the myths and the tools, providing a foundation for better understanding and better design decisions.

Modular Approach to Rugged COTS Data Storage Selection

October 31, 2014

Data storage plays a key role in Defense and Aerospace deployed data gathering system applications. Data gathering and storage device components must frequently be deployed in harsh military environments onboard platforms such as fixed-wing aircraft, helicopters, and armored vehicles, all of which require a high level of system ruggedness. Data storage devices on these platforms are used to store critical and valuable data captured from sensors or subsystems during a mission or operational exercises. The valuable data captured in the field is often sensitive and must be protected from unauthorized access both during and after the mission. Once the mission is completed, the captured data typically needs to be transported from the platform to a different location, such as a ground station, for analysis or safekeeping.

This white paper will provide guidelines for selecting the appropriate rugged Commercial-Off-the-Shelf (COTS) data storage solution for use in various types of data gathering applications.

Video Management Systems Support Services

October 31, 2014

Traditionally there has been a difference between the product support models provided by mission equipment manufacturers and the requirements for aircraft fleet maintenance and equipment certification. Aircraft mission equipment life time cycles are longer than standard commercial product life times.
 
The integration of different products from multiple suppliers, can often lead to problems with connectivity and functional inconsistencies. This is a common problem attributed to mismatches between different suppliers’ documentation details and product functions. End user training is a common program requirement; this is expensive to provide if a training course has to be created by an installer, solely for any particular program. Some programs require complete control or visibility over the internal build configuration of all units being fitted to the aircraft.

Curtiss-Wright Video Management System (VMS) support services resolves these issues, making it easier for mission equipment installers to work with our products.

Challenges of Designing Multi-Channel, High-Speed Data Recording and Playback Systems

October 6, 2014

Data recording and playback systems provide valuable capabilities in ISR applications. The proliferation of sensors in defense & aerospace Intelligence, Surveillance and Reconnaissance (ISR) applications has led to a tremendous amount of high-speed data that must be recorded and accessible for playback being produced.

This is especially true in the defense and aerospace industry. These sensors, such as radar, sonar, FLIR, RF tuners, MRI and cameras, use various high-speed I/O transport protocols to move this high-speed data. These protocols such as include Gigabit Ethernet (GbE), Serial FPDP (sFPDP) and 10 GbE move the data they have capture.

When developing their solution, designers must address their program’s unique performance and environmental requirements. In addition, other less obvious system characteristics, such as timing and channel synchronization, flexible storage options and data offloading, need to be considered.

Curtiss-Wright’s Multi-Channel, Synchronized Data Recording and Playback Systems address these challenges and provide the necessary capabilities to support today’s most demanding ISR applications.

Consolidate Line Replaceable Units (LRU) while considering strict Size, Weight and Power (SWaP) constraints

October 6, 2014

Despite the current budget woes of defense departments, the demand continues for delivering more performance and improved functionality from rugged computers and communications subsystems. With the requirement for ever increasing semiconductor integration, more subsystem functionality is being squeezed into compact systems. Military vehicles are taking advantage by now combining what historically have been separate systems functions. This has fuelled demand for the consolidation of Line Replaceable Units (LRUs) — packing more into a single box. Modern state-of-the-art equipment offers the DOD more than legacy products—one subsystem can now integrate the capabilities of multiple subsystems. To achieve these savings, rugged commercial-off-the-shelf (COTS) computing subsystems are purchased versus custom MIL-spec alternatives.

Flexible D2D Chassis Reduce Costs & Simplify Schedules

October 6, 2014

Because requirements change and designs evolve as a program moves from development to demonstration and, finally, deployment, programs typically pay, in full, for new chassis technology at each phase.  Now there is another option; Development to Deployment (D2D) Chassis are designed to be easily configured and reconfigured for the development phase, demonstration phase and deployment phase. They minimize both the overall program cost of chassis acquisition and total amount of hardware that has to be acquired.

In the white paper is a detailed description focusing on reuse and flexibility.  By reusing most of the chassis components for all phases, and only replacing or adding pieces as needed, overall program costs are sharply reduced.  Flexibility comes from fans and power supplies, that are swapped out to transition from Commercial to Mil Standard, and from removable top/bottom ‘hats’ that are added for cable routing after the development stage.
