## JANNAFM&SS Integrated Health Management / LPS Engine Health Management Panel Meeting

- 9 December, 2008
**Orlando, Florida**
** ****M&SS Panel Chairs: Mr. R. Scott Hyde, ATK Launch Systems and Dr. Ashok N. Srivastava, NASA ARC**
**LPS Panel Chair: James A. Larkin, **
**Pratt and Whitney Rocketdyne**

## IHM Definition

Integrated Health Management (IHM) is the art and science of managing off-nominal conditions that systems may encounter during their operational life cycle. Integrated Health Management includes system design, vehicle safety, and intelligent systems

**Integrated Health Management (IHM) Panel**

## Panel Objective

. The panel objective is to provide a forum to promote advancement and creation of industry best practices for IHM of propulsion systems to reduce the cost of maintainability and increase the reliability of propulsion systems. This panel addresses all technologies required to build diagnostic (health state determination), prognostic (future health state determination), and data management/mining systems required to manage the health of propulsion elements.

## Engine Health Management (EHM) Panel

- The purpose of the Engine Health Management (EHM) Panel is to examine the potential use of health management technology to improve operability, reusability, and safety of liquid rocket engine systems. The EHM panel has identified several tasks to undertake, including the creation of an EHM roadmap to determine the state of the art and technology readiness level; the development of a conceptual analysis of health management requirements for liquid rocket engine systems; and the determination of data analysis and fusion parameters and concepts for a liquid engine health management system – work to be done in conjunction with JANNAF Modeling and Simulation Integrated Health Management Panel activities.

## IHM/EHM Panel History

- Numbers in “( )” indicate withdrawn papers

## IHM/EHM Panel Accomplishments

- Provided input to M&SS annual report
- Participated in “Rocket Propulsion Health Management Sensor Workshops 1, 2, 3 and 4”, Jointly organized by the M&S, LP and S&MB Subcommittees
- WS results documented in M&SS annual report and presentation by Lt Adam Verdon at this conference.
- Organized “Integrated Health Management Legacy Session: Propulsion Failure History”
- Assisting with the development of the IHM/EHM business case with James H. MacConnell
- Provided cross-agency guidance for integrated studies in propulsion health management (NASA/Air Force)
- Supported planning telecons

## Task Review/Action

| Task | Task Description | Recommended Action | Status |
| --- | --- | --- | --- |
| 1 | Best Practices - Find leaders for each propulsion type | Get TSG Support to in making assignments | In-work, need volunteers |
| 2 | Create position paper for each propulsion type | Propulsion type leads | Solids complete
Others ? |
| 3 | Create IHM glossary/definitions put into Wiki-Type environment (DASHLINK  not ITAR compliant) | Scott Hyde lead with volunteers | 107 terms |
| 4 | Participate in creation of JANNAF “IVHM Sensors for Space Transportation” type document  | Actions made and documented. | Slow progress |
| 5 | Create Wiki-Type environment for sharing propulsion sensor information | Plan WS to discuss issues and establish direction. NASA ARC DASHLINK is a non-ITAR compliant option | WS Friday, 12 Dec |
| 6 | Broaden visibility and acceptability of IHM/EHM capabilities within the HARDWARE design communities | Cross-pollenate IHM/EHM Panels and Materials conference activities. Target the National Space & Missile Materials Symposium (NS&MMS) as first opportunity | IVHM Workshop planned for NSMMS in June 2009 |

## Possible Sessions for Next M&SS Meeting
