Case Study: HH-60 Symbol Generator Power Supply
Background and Current Status
- Power supply for the HH-60 symbol generator
- No source of supply resulting in negative impacts to mission capability
- Original design featured multiple noise isolation inductors and contained several obsolescence issues
- Maintaining original form factor, aircraft interface, and functionality
- New design will center around a DC-DC converter module
- Will reduce the total number of parts
- Will improve the MTBF
- Will increase efficiency by 20-25% and reduce the thermal output
- Currently performing reverse engineering, reengineering, and design
