Summary

The Department of Defense (DOD) is seeking proposals for the topic "DACS COPV Helium Pressurant Measurement" as part of their SBIR 24.2 Annual solicitation. The research objective is to develop and demonstrate an accurate and effective means of measuring the pressure in the Terminal High Altitude Area Defense (THAAD) Divert and Attitude Control System (DACS) Composite Overwrapped Pressure Vessel (COPV). The THAAD DACS COPV is pressurized with helium during assembly, and the goal is to find a non-invasive and non-destructive method to verify the integrity of the COPV by measuring the pressure within it. The Phase I of the project requires the proposer to have a concept for a workable prototype or design that addresses the basic capabilities of the objective. Feasibility and preliminary understanding of the technology to be applied in Phase II should be demonstrated through technical reports, test data, prototype designs/models, and performance goals/results. In Phase II, the proposer should develop and demonstrate an accurate and effective means of measuring the pressure in the THAAD DACS COPV. The method of measurement should be non-destructive, non-invasive, and capable of being used without removing the COPV from the DACS or the DACS from the Missile Round (MR). The method should also be capable of measuring the pressure during post-production activities. The concept has potential applications beyond helium pressurant systems and could be developed for other government programs. Relevant references include papers on non-intrusive pressure sensors and determining pressure inside thin-walled vessels using strain measurements. The deadline for proposal submission is June 12, 2024. For more information and to submit a proposal, visit the DOD SBIR 24.2 Annual solicitation page on grants.gov.

Description

OUSD (R&E) CRITICAL TECHNOLOGY AREA(S): Mission Readiness &Disaster Preparedness;

 

OBJECTIVE: Develop and demonstrate an accurate and effective means of measuring the pressure in the Terminal High Altitude Area Defense (THAAD) Divert and Attitude Control System (DACS) Composite Overwrapped Pressure Vessel (COPV).

 

DESCRIPTION: The THAAD DACS COPV is pressurized with helium during assembly.  The THAAD Missile Product Office (THR) is seeking a precise, non-invasive, non-destructive means of verifying the integrity of the COPV by measuring the pressure within the COPV upon DACS installation and whenever MRs are returned for Stockpile Reliability Testing (SRT).

 

PHASE I: Phase I-like proposals will not be evaluated and will be rejected as nonresponsive.  For this topic, the Government expects the small business would have accomplished the following in a Phase I-like effort via some other means, e.g., independent research and development (IRAD) or other source, a concept for a workable prototype or design to address, at a minimum, the basic capabilities of the stated objective above.  Proposal must show, as appropriate, a demonstrated technical feasibility or nascent capability.  The documentation provided must substantiate the proposer’s development of a preliminary understanding of the technology to be applied in their Phase II proposal in meeting topic objectives.  Documentation should comprise all relevant information including but not limited to, technical reports, test data, prototype designs/models, and performance goals/results.  Feasibility = maturity and what have you already done/validated.  

 

Proposers interested in participating in Direct to Phase II must include in their responses to this topic Phase I feasibility documentation that substantiates the scientific and technical merit and Phase I feasibility described in Phase I above has been met.  (i.e., the small business must have performed a proof of concept like “Phase I” component and/or other validation in a relevant environment, and/or at a much higher TRL level (5 or higher) and describe the potential commercialization applications.  The documentation provided must validate that the proposer has completed development of technology in previous work or research completed.) 

 

IRAD work, previous Phase I/Phase II work:  Documentation should include the most relevant information including, but not limited to:  technical reports, test data, prototype designs/models, and/or performance goals/results.  Work submitted within the feasibility documentation must have been substantially performed by the proposer and/or the principal investigator (PI).

 

PHASE II: Develop and demonstrate an accurate and effective means of measuring the pressure in the THAAD DACS COPV.  The means of measuring pressure must be non-destructive and non-invasive to the DACS system and capable of being used without removal of the COPV from the DACS, or removal of the DACS from the MR.  The method of measurement should be capable of measuring the pressure initially put into the COPV when filled with helium (pre-MR assembly) and capable of measuring the pressure within the COPV during MR SRT, or other post-production activity.  The means of measurement should not result in the loss of helium from the COPV and should be precise enough to determine the capability of the COPV to provide pressurant to support a worst-case THAAD Missile engagement.  The method of measurement should be demonstrated within the THAAD DACS assembly facility and the THAAD test area used for SRT.

 

PHASE III DUAL USE APPLICATIONS: This concept has the potential for applicability to other types (i.e. other than helium) of pressurant systems. The concept could also be developed for application to other Government programs.

DOD SBIR 24.4 Annual - Lightweight Longwave Bolometer Sensor Components
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "Lightweight Longwave Bolometer Sensor Components" as part of the SBIR program. The objective of this topic is to develop components that enable low size, weight, and power (SWAP) thermal bolometer-type longwave thermal sensor payloads. These components should have equal or better performance than current commercial offerings while driving down SWAP. The components of interest include lens, focal plane, and readout and processing embedded hardware. The components should be ready for integration into a camera module by the end of Phase II. Thermal longwave infrared (LWIR) capabilities are crucial for many Army applications, especially for small Unmanned Aircraft Systems (UAS). However, the size, power, and weight constraints often limit the performance of these sensors. This topic aims to develop components that reduce the weight of thermal payloads while increasing their capabilities and keeping unit costs low. The project will have a Phase I and Phase II, with Phase I proposals accepting a cost of up to $250,000 for a 6-month period of performance. During Phase I, firms should design a proposed component with stakeholder input, analyze the SWAP-C impact of the component, and discuss how it will support the objective sensor payload. Phase II will involve completing the component design, fabricating, testing, and characterizing the component for integration into a lightweight sensor payload. Firms will also refine the design, define relevant interfaces, and lay out a high-level plan for integration. The potential applications of this research include smartphone camera augmentation, UAV camera augmentation, home security systems, and climate tech development. The project references academic research on bolometer manufacturing methods and the efficacy of leveraging colloidal quantum dots (QDs) for IR light sensing. Military contractors have also contributed to the research in the LWIR sensor and bolometer manufacturing spaces.

The open date for proposals is October 3, 2023, and the close date is March 31, 2025.
