Air Force EHM+DRC Program update

Since program inception in 2004, the Engine Health Management Plus Data Repository Center Program continues to maintain momentum and grow. RJ Lee Group’s success on the program is attributed to ongoing top performance and commitment to the Air Force. Our current EHM+DRC contracts extend through 2012 valued at $15.5M.

The program continues supporting Cannon AFB (New Mexico) and Buckley AFB (Colorado) during Field Service Evaluations of the system, and plans to bring Shaw AFB (South Carolina) online. Currently, F110 engine data (F-16 fighter aircraft) and F108 engine data (KC-135 refueling and RC-135 reconnaissance aircrafts) (both GE engines) are being uploaded daily to the EHM+DRC via the internet using secure encryption. Upcoming integration into the EHM+DRC includes the following engines: F100 (P&W engine used in the F-15 and F-16 fighter aircraft), F101 (GE engine used in the B-1 aircraft as a strategic bomber) and TF34 (GE engine used in the A-10/OA-10 aircraft for close air support of ground forces).

New EHM+DRC Initiatives

The EHM+DRC program expansion includes Reliability Centered Maintenance (RCM) application and federated architecture implementations. RCM is an industrial improvement approach focused on identifying and establishing the operational, maintenance, and capital improvement policies that will manage the risks of equipment failure most effectively. RCM is an integral part of engine life management for all engines covered by this instruction. RCM is tailored for engine life management as an analytical process to determine the appropriate failure management strategies, including preventive maintenance requirements and other actions that are warranted to ensure safe operations while balancing readiness and costs.

RJ Lee Group is teaming with Northrop Grumman, General Electric and Standard Aero in joint partnership with the Air Force to develop the RCM applications within EHM+DRC.

RJ Lee Group federated architecture implementation, whether database or application, includes the union of independent disparate systems under a single cohesive view. There are two main types of systems within a federated portal architecture, providers and consumers. The providers are systems that publish data and application services that may be specific to a singular business domain. The consumer system aggregates the content of the remote providers into a single view with transparent boundaries.

The EHM+DRC is developing toward a federated architecture following two key architectural components: Service-Oriented Architecture (SOA) and portlets. SOA and portlets are two distinct methodologies that compliment each other well. SOA offer building blocks from each domain that can be aggregated and repurposed to create portlets that offer domain specific functionality. These portlets are then aggregated together to form a portal which offers consolidated access and cross-cutting functionality such as authentication/authorization.

Air Force EHM+ Program update

The Engine Health Management Plus (EHM+) program is designed to optimize operational readiness through affordable, integrated, embedded diagnostics and prognostics. EHM+ is implemented to improve maintenance ability and responsiveness, increase operational availability, and reduce life cycle total ownership costs. The goal of EHM+ is to tie together Engine Trending and Diagnostics (ET&D) and Reliability Centered Maintenance (RCM) to enable the commander to make decisions based on weapon system capability to meet real-time operational needs. The EHM+DRC system is a key component underneath the overall EHM+ program.

RJ Lee Group is the prime contractor teaming with Southwest Research Institute (SwRI as subcontractors) supporting the Engine Health Management Plus (EHM+) program for the USAF Propulsion Community.

New Contracts

Air Force CBM+ Research Environment
RJ Lee Group was recently awarded a multi-million two year contract as the prime contractor for the Condition Based Maintenance Plus (CBM+) program. CBM+ is based on the CBM system that uses real-time data to prioritize and optimize maintenance resources to determine the equipment’s health, and act only when maintenance is actually necessary; plus “+” adds the prognostics component of analysis. It is Department of Defense policy that CBM be “implemented to improve maintenance agility and responsiveness, increase operational availability, and reduce life cycle total ownership costs.”

The contract includes developing the CBM+ Research Environment for the Air Force (Air Staff HQ at the Pentagon). RJ Lee Group will be teaming with General Dynamics to develop the CBM+ Research Environment within the existing EHM+DRC environment located at RJLG Data Center in the EverGreene Technology Park located in Waynesburg, PA. RJ Lee Group will provide a primary focus on program management and CBM+ software architecture and implementation. Whereas, General Dynamics will provide a primary focus on CBM+ subject matter and domain expertise, and work related to Non-EHM+DRC domain areas for the CBM+ Research Environment such as ASIMIS, ECSS and GCSS DoD systems.

RJ Lee Group plans to develop the CBM+ Research Environment using a federated architecture approach. The CBM+ Research Environment will consist of federated systems that are organized in hierarchical structure where a consumer of one set of remote services can serve as a provider to another consumer. In real terms this would be like the EHM+DRC (engines domain) and ASIMIS (aircraft domain) consuming remote propulsion data services and providing those same services to the Federated DoD or CBM+ Research Environment.
