Reflections on COTS in Avionics/Vetronics

  1. 1. Reflections on COTS in Avionics/Vetronics The Use of COTS Assemblies in Harsh Environment Two-Level Maintenance Systems – May 12 th , 2005 James A. Robles, Senior Technical Fellow The Boeing Company Phn: (206) 655-9062 Email: [email_address] BOE 042105-077
  2. 2. Context – The Environment Changed We Won the Cold War Control of the Electronics Industry Acquisition Reform New Generation of Users <ul><li>1994 Perry Memo </li></ul><ul><li>Streamline procurement of reduce cycle time and cost </li></ul><ul><li>Strengthen technology/industrial base </li></ul><ul><li>Increased access to advanced technologies </li></ul><ul><li>Move away from the military specification system </li></ul><ul><li>Not My Generation </li></ul><ul><li>Better educated and more aware of technology </li></ul><ul><li>Not willing to tackle a difficult job with obsolete hardware </li></ul><ul><li>Useful life reduced to correspond to desired technology refresh cycle </li></ul>Defense Outlays As a Share of Gross Domestic Product 2 4 6 8 10 12 50 60 70 80 90 00 3.0 GDP (%) 4.4 4.7 11.9% 9.1% 6.3% Year
  3. 3. What My Customers Require on Advanced Fighters, Helicopters, and Ground Vehicles <ul><li>Minimize Total Ownership Cost (TOC) </li></ul><ul><ul><li>Development Cost </li></ul></ul><ul><ul><li>Unit Recurring Flyaway (URF) Cost </li></ul></ul><ul><ul><li>Operation and Support (O&S) Cost </li></ul></ul><ul><li>High functional density to minimize weight and volume </li></ul><ul><ul><li>Thermal density (watts/cm) </li></ul></ul><ul><li>Perform reliably in harsh environment </li></ul><ul><ul><li>Reduce thermal strains to improve inherent reliability </li></ul></ul><ul><ul><li>Uniformity of temperature distribution across module </li></ul></ul><ul><ul><li>Exposure to coolant </li></ul></ul><ul><ul><li>Complexity </li></ul></ul><ul><li>Compatibility with two-level maintenance </li></ul><ul><li>Facilitate insertion of new technology and mitigation of component obsolescence </li></ul><ul><ul><li>Thermal margin </li></ul></ul>
  4. 4. Obstacles to Wider Usage of Available COTS <ul><li>Low Functional Density </li></ul><ul><li>Current standards do not meet the need </li></ul><ul><ul><li>IEEE 1101.1 Air Cooled </li></ul></ul><ul><ul><li>IEEE 1101.2 Conduction Cooled </li></ul></ul><ul><li>Not Compatible with Two-Level Maintenance Requires an ESD protected connector and covers for handling protection </li></ul><ul><ul><li>Two to three times O&S cost penalty </li></ul></ul><ul><ul><li>F/A-22 example </li></ul></ul><ul><li>Lack of a Standard for Environments </li></ul><ul><li>A Gaping hole in our “open architectures’ </li></ul><ul><ul><li>Exposes programs to risk with each DMS fix or upgrade cycle </li></ul></ul>
  5. 5. Enablers for Wider Usage of Tomorrow’s COTS <ul><li>Higher Functional Density </li></ul><ul><li>Standards under development will meet the need </li></ul><ul><ul><li>VITA 46 </li></ul></ul><ul><ul><li>VITA 48 </li></ul></ul><ul><li>Compatible with Two-Level Maintenance </li></ul><ul><li>VITA 46 and VITA 48 will have an ESD protected connector </li></ul><ul><li>VITA 48 will provide optional covers for ESD and handling </li></ul><ul><li>We Have a Standard for Environments </li></ul><ul><li>Fills the gaping hole in our “open architectures’ </li></ul><ul><ul><li>ANSI VITA 47 is released </li></ul></ul>
  6. 6. The Thermal Management Challenge and Answer <ul><li>Thermal management challenge </li></ul><ul><ul><li>More heat to remove </li></ul></ul><ul><ul><li>Less “potential” to drive it out </li></ul></ul><ul><li>Consequences </li></ul><ul><ul><li>Unit Recurring Flyaway cost </li></ul></ul><ul><ul><li>Functional density – fuel cost (O&S cost), lethality, survivability. </li></ul></ul><ul><ul><li>Reliability (O&S cost) </li></ul></ul><ul><ul><li>Margin for DMS fixes </li></ul></ul><ul><ul><li>Margin for technology insertion </li></ul></ul><ul><li>The answer --- VITA 48 </li></ul><ul><ul><li>Enhanced conduction cooling </li></ul></ul><ul><ul><li>Liquid Flow Through Cooling </li></ul></ul><ul><ul><li>Spray Cooling </li></ul></ul>BOE 042105-077
  7. 7. Outlook for the Future <ul><li>We are addressing the obstacles to wider usage of COTS assemblies in avionics/vetronics </li></ul><ul><li>The environment will continue to change in ways that encourage the use of COTS </li></ul><ul><li>We are at a tipping point – much wider use of COTS assemblies in harsh environment two-level maintenance systems </li></ul>
