OBJECTIVE: Develop integrated sensor technologies that can be incorporated into composite primary structures to allow for the monitoring and characterization of the structuresí behavior to support their development, production, and sustainment.
DESCRIPTION: Composites materials are used extensively throughout the aerospace industry due to their great specific strength and stiffness. Unlike traditional metallic components, the ultimate performance of composites can be much harder to characterize and monitor because they are a product of the manufacturing process, can be susceptible to aging issues, and damage may be difficult to identify. Traditionally strain gages are used to characterize a structure and can only sense a very limited portion of that structure, are labor intensive to install, and can be susceptible to handling damage. Traditional strain gages and the associated wiring are generally only used for limited test activities and were not intended for prolonged monitoring and for durability over the deployment of the system. Embedded sensors would allow the structural integrity and behavior of composite structures to be effectively monitored to address the previously described challenges throughout the entire product lifecycle. This will help improve the depth of understanding of these products and assist in driving down lifecycle costs, particularly in the area of sustainment. This sensing system should be designed to operate within the environmental constraints that would be expected of aerospace composites and should be mindful of size and weight to minimize their impact to the flight vehicle while balancing the performance of the sensor.
The sensor system should consider the following parameters:
Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by DoD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence Security Agency (DCSA). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this project as set forth by DCSA and SSP in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advanced phases of this contract.
PHASE I: Define and develop inspection and sensor concepts and assess their feasibility. Examine concept formulation, development, and possible validation that could include subscale demonstration, including data logging operations. The Phase I Option, if exercised, will include the initial design specifications and capabilities description to build a prototype solution in Phase II. Prepare a Phase II plan.
PHASE II: Develop and validate a prototype (not necessarily hardware). Solidify the process for designing and incorporating the sensors into a variety of structures, such as primary aerospace vehicle structures of complex geometry, specific detail will be provided after award. The cost to procure and implement the system should be assessed. Quantify the performance of the embedded sensor, corresponding data logging equipment, and the sensorís impact on the system.
It is probable that the work under this effort will be classified under Phase II (see Description section for details).
PHASE III DUAL USE APPLICATIONS: Work with the Navy to formalize the process for the final design, integration, calibration and/or correlation of the integrated sensors for use to help with the detection of the early failure of parts, which will aid in the reliability of systems and mutually benefits the Navy and aerospace industry. This will include the qualification of the sensing system for use on Navy and aerospace primary and secondary structures.

** TOPIC NOTICE **
The Navy Topic above is an "unofficial" copy from the overall DoD 21.2 SBIR BAA. Please see the official DoD Topic website at rt.cto.mil/rtl-small-business-resources/sbir-sttr/ for any updates.
The DoD issued its 21.2 SBIR BAA pre-release on April 21, which opens to receive proposals on May 19, 2021, and closes June 17, 2021 (12:00pm edt).
Direct Contact with Topic Authors: During the pre-release period (April 21 thru May 18, 2021) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic. Once DoD begins accepting proposals on May 19, 2021 no further direct contact between proposers and topic authors is allowed unless the Topic Author is responding to a question submitted during the Pre-release period.
SITIS Q&A System: After the pre-release period, proposers may submit written questions through SITIS (SBIR/STTR Interactive Topic Information System) at www.dodsbirsttr.mil/topics-app/, login and follow instructions. In SITIS, the questioner and respondent remain anonymous but all questions and answers are posted for general viewing.
Note: Questions should be limited to specific information related to improving the understanding of a particular topicís requirements. Proposing firms may not ask for advice or guidance on solution approach and you may not submit additional material to the topic author. If information provided during an exchange with the topic author is deemed necessary for proposal preparation, that information will be made available to all parties through SITIS. After the pre-release period, questions must be asked through the SITIS on-line system.
