TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The availability of an air vehicle to perform missions or generate sorties is negatively impacted by time spent on the ground due to scheduled servicing and maintenance. Condition Based Maintenance (CBM) helps maximize the availability of air assets by servicing the air vehicle based on actual condition as opposed to a fixed number of operating hours. Prognostics and Health Management (PHM) enables improved CBM on air vehicles by comparing in-situ sensor data to prognostic models of components and subsystems to predict wear as it occurs. Integration of these PHM systems with an autonomic logistics infrastructure can lead to even greater increases in sortie generation rates and decreases in maintenance cost and logistics burden by eliminating unnecessary preventative maintenance as well as identifying failures occurring outside the normal scheduled maintenance cycle. Aurora's innovative approach utilizes information from existing sensors (i.e., does not require additional sensors added to the vehicle, hence, 'sensor-free') to determine PHM.
Current implementation of PHM is focused on new designs of manned aircraft to allow co-development of the PHM system and its specific sensors. Unmanned Aerial Systems (UAS) have sensors and subsystems already installed that can provide the capability for a PHM retrofit on in-fleet systems. UAV specific subsystems, such as the autopilot, also provide the opportunity for new PHM capabilities beyond those considered in manned aircraft.

Aurora proposes the Integrated Vehicle Health Management System (IVHMS). Aurora's IVHMS will compare models of the aircraft in different configurations to an estimate of the current state of the aircraft in order to generate a better understanding of the real-time operating condition of the vehicle and its constituent components. The IVHMS uses these capabilities to generate a vehicle-wide identification of systems in order to detect faults as they influence overall performance.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed Aurora IVHMS will use the BAMS/Global Hawk class UAS as the vehicle on which to base development. As such, NASA will have the opportunity to retrofit their Global Hawk with the Aurora IVHMS. Because NASA's Global Hawk is used in extreme flight environments, such as hurricane and severe storm research, such a PHM system would provide valuable vehicle state information. It is anticipated that other NASA vehicles would also benefit from the Aurora IVHMS system as it matures and is developed for other families of manned and unmanned air vehicles.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The initial Aurora IVHMS will be focused on as single UAS, such as BAMS, marketed as either a retrofit or for incorporation in the production process. Aurora believes the same IVHMS can, with minimal modifications, also be marketed as a retrofit to the existing Global Hawk fleet. The combined inventory of RQ-4 A,B, and N vehicles is expected to continue growing in the immediate future and will provide a steady market for the Aurora IVHMS as the process of developing Aurora IVHMS products for other UAS families begins. It is also expected that Aurora IVHMS will be an appealing addition to other UAS applications, such as Auroras own products like the Orion UAS.
