Study Overview


Study Overview• Define and document

• The potential impact of an optimized Integrated Health Management System on

• Design of Unmanned Air Vehicles (UAVs)• Design of Space Operating Vehicles (SOVs)

• The technology issues and shortfalls that would need to be addressed to achieve that impact

• Critical technologies that have the potential to address those shortfalls• A business case analysis that provides rationale for:

• Designing for/with ISHM• Prioritization of technical shortfalls• Pursuing specific critical technologies

• The preferred programmatic approach to pursuing those technologies• Collaborative Approaches (Consortia, Collaborative Programs)• Suite of Conventional CRAD Programs

• Challenge is Balance between Program/Initiative building and Technical/Business Assessment

Task 1:• Study Development

1. define the specifics of the study with the government ISHM IPT, 2. assemble the collaborative ISHM team that will execute the study under

the leadership of the Wright Brothers Institute, 3. define the needed effort for Tasks 2 and 3, and 4. identify the government and industry resources required to execute the

study.

Task 2:• Define the potential impact of an optimized Integrated

Health Management System on the design of Unmanned Air Vehicles (UAVs).

• Assuming an ideal health management capability, • which would include available sensors with required performance, durability and

reliability, the Wright Brothers Institute and the collaborative ISHM team shall:• perform a business case analysis to examine

• the monetary trades, system performance, mission availability, and procurement size impact for a new acquisition

• if the design accounted for the benefits of health monitoring and management.

Task 3:• Define the potential impact of an optimized Integrated

Health Management System on the design of Space Operating Vehicles (SOVs).

• Assuming an ideal health management capability, • which would include available sensors with required performance, durability and reliability,

• perform a business case analysis to examine • the monetary trades, system performance, mission availability, and procurement size impact for a

new acquisition • if the design accounted for the benefits of health monitoring and

management. Task 4:

• Compile and develop a final report that will include • the findings of the study as well as the required R&D to achieve an optimized ISHM. • A summary of the findings quantifying the benefits of the proposed ISHM system and

documentation of the business decisions made in selecting the attributes of the ISHM system will be included.

• a list of the technical challenges and critical technologies that need to be further developed or desired.

• Identification of the required sensors, sensor accuracy and reliability necessary for the OEM to seriously consider its use in an ISHM system.

• Definition of any shortfalls in computational, inspection and manufacturing capability which may prohibit the implementation of an ISHM system


Overall Objectives

• To define the overall scope and key research areas of a cross technical directorate effort in ISHM

• To define and assess cost, performance, and other benefits that may be achieved by including ISHM capabilities in the conceptual design of aerospace vehicles.

• study how ISHM might influence the design of the vehicles and the system as a whole.

• quantify the benefits of the “proposed” ISHM system • document the business decisions made in selecting the attributes of the ISHM system

• To identify the critical technology elements required to realize those benefits

• Define technical challenges and critical technologies that need to be further developed.

• Identify the required sensors, sensor accuracy and reliability necessary for the OEM to seriously consider its use in an ISHM system.

• Define shortfalls in computational, inspection and manufacturing capability which may prohibit the implementation of an ISHM system will be defined

• To establish a roadmap for pursuing those technologies.


Overall Objective

• To define the overall scope and key research areas of a cross technical directorate effort in ISHM• Focus on collaborative development of:

• Technical focus areas• Benefits definition and analysis

• True INTEGRATION vs. Cross-Functional Development

Define Benefits• To define and assess cost, performance, and other benefits that may be achieved by including ISHM capabilities in the conceptual

design of the vehicles. • Not just “What are the benefits if the design accounted for the benefits of health monitoring and management.” • Rather “Would we design differently if the ideal ISHM system existed and what would be the benefits of THAT design/system”

Opens up the discussion but presents real challenges

Establish development plan • To establish a roadmap for pursuing those technologies.

• Transform the set of technology needs into a prioritized and structured technology development thrusts

• Integrate the technology thrusts into a set of discreet, manageable but inter-dependent efforts

• Define the resources needed for those efforts and the appropriate “team” construct to conduct those efforts successfully
