Capabilities
DMA has a flat, highly responsive management structure. In our programs, there is never more than one person between our customers and senior management who has the authority to commit the company. Our engineering management actively participates in all projects, ensuring our customers have continual contact with the highest levels of DMA technical management.
System Design
Whether the new system will reuse current system modules or be a full system design, DMA understands the relationship between various componets and how the completed system interfaces into the system as a whole. We have designed both reuse and complete systems for military applications.
Previous experiences include:
- Electronic Control Unit and Loader's Weapon Control Panel for AC-130U Trainable Gun Mount (AC-130U)
- Display software for the Terrain Following program (MC-130J)
Test and Support Equipment
DMA test engineers have decades of experience defining Measure of Effectiveness (MoEs), Measure of Performance (MoPs), and associated test events for SOF C-130 aircraft. For example, for testing the AC-130U’s fire control system modification, MoEs/MoPs were established from the AC-130U’s Prime Item Development Specification including the required Circular Error Probable (CEP) for accuracy of each weapon system on the AC-130U.
DMA uses proven planning techniques during the development of MoEs/MoPs, including process analysis, design or engineering analysis, matrix analysis, and dendritic analysis. Our planning process is iterative. We use the results of each test to help in the design and planned execution of future tests.
Previous experiences include:
- Designed and produced card edge programmer for software loading in the ASQ-204 Control Display Set
- Designed custom test set for component fault isolation on APQ-150 radar
- Designed Heads-Up Display (HUD) tester for Intermediate level maintenance
- Functional test of redesigned Control Display Unit (CDU) (AC-130H, MC-130E, HH-60)
- Functional test of redesigned Display Generator Unit (DGU) (AC-130H)
- Functional test of redesigned Electronic Control Unit (ECU) and Loader Weapon Control Panel (LWCP) (AC-130U)
- Functional test of redesigned Data Transfer System (DTS) (AC-130H, MC-130H, HH-60)
- Designed and tested Tactical Interface Data Acquisition System (TIDAS) rack for use on multiple aircraft test flights.
- Designed and built engineering test bench to verify the Data Transfer System (DTS) (AC-130U, MC-130H, C-130 SCNS)
Independent Verification and Validation (IV&V)
Our working knowledge of DO-178C (Software Considerations in Airborne Systems and Equipment Certification), DD-254 (Design Assurance Guidance for Airborne Electronic Hardware), and military safety standards (MIL-STD-882E) allows us to provide a trusted source of turn-key IV&V capabilities.
Previous experiences include:
- Testing and analysis to support Modified Airworthiness Certification (MAC) and Non-Nuclear Munitions Safety Board (NNMSB) approval for multiple projects
- Responsible Test Organization (RTO) for the AP-102 Mission Computer Replacement Program (MCRP)
R&D
As an Engineering Services provider, one of our core competencies is providing R&D analysis and solutions for our customer’s unique requirements. Keys to providing comprehensive solutions include development of an accurate Requirements Traceability Matrix (RTM) and performing an Analysis of Alternatives (AoA) to determine the available options which meet the requirements and provide the best value to our customer. DMA sees these steps as being the primary effort to narrow the available Hardware/Software options to the best candidates leading to prototype development. DMA staff engineers consistently perform successful prototype and production efforts.
Previous experiences include:
- Using our own internal Research and Development funds, DMA developed DMAnalyze, a 1553 Chapter 10 Data Reduction Software Tool. The tool applies platform specific, XML based ICD, to Chapter 10 formatted telemetry data which produces readable data in engineering units. DMAnalyze functions include advanced data export, search, fault isolation, and statistical analysis packages.
NAVY Small Business Innovation Research (SBIR) Award:
- Open Systems Technologies (HOST) Conformance Tool - Developed an innovative conformance test tool to support and add automation to the verification of hardware conformance to HOST Standards.
- The overall technical objective was to establish the feasibility of developing an automated conformance validation tool for HOST compliant devices. A challenge for HOST conformance testing is that the standards define an overarching set of logical interfaces in the Tier 1 standard which are then further refined and applied to core technologies featuring unique physical interfaces in Tier 2 standards. In addition, product specific functions are defined in unique Tier 3 Component Specifications. In order to be a feasible solution, the tool must be adaptable to provide validation for all three tiers of HOST specifications
Simulation
Whether the new system will reuse current system modules or be a fresh complete system redesign, DMA understands that the relationship between various components and how the completed system interfaces with the entire system is paramount. We have designed both reuse and complete systems for military applications.
Previous experiences include:
- Electronic Control Unit (ECU) and Loader's Weapon Control Panel (LWCP) for Trainable Gun Mount (AC-130U)
- Software support for the Terrain Following program (MC-130J)
Logistics
DMA has experience in shipping, warehousing, kitting, PCA, inventory control or Diminishing Manufacturing Sources and Material Shortages (DMSMS) management.
Previous experiences include:
- Integral part (SME) of the APQ-170 Service Life Extension Program (SLEP) Integrated Product Team (IPT)
- Ongoing support in identifying alternative sources of supply and qualifying form, fit, and function replacements for DMSMS issues
Fabrication & Modification
We provide the engineering and technical support required to integrate, maintain, repair, modify, and sustain systems and support equipment throughout the life cycle. DMA’s current contractual requirements include aeronautical, mechanical, structural, electrical, and electronics engineering support for the SOF/PR integration efforts managed by the Air Force (AFLCMC/WIUAH and WIUEA). This encompasses SOF legacy systems as well as new modification and integration requirements.
Previous experiences include:
- Custom chassis and internal wiring harnesses for multiple form, fit, and function LRU replacements
Component Redesign
Whether facing Diminishing Manufacturing Sources and Material Shortages (DMSMS) issues or are looking to incorporate technology insertion, DMA has the experience to handle your toughest redesign requirements
1. Amplifiers
2. Circuit Cards
3. A/D and D/A
4. Board Site Programmers
Previous experiences include:
- Amplifier Module for APG-70 radar (F-15)
