Description

The Department of Defense (DOD) is seeking proposals for an adjustable shock absorber for oversized applications. The Navy branch is specifically interested in developing a large shock absorber that can be tuned prior to compression to absorb energy and shock that varies in magnitude. The shock absorber should be larger in size than typical ones and capable of being adjusted/programmed to optimize resistance given the expected initial conditions. The technology should convert kinetic energy to another form, such as heat or electricity, that can be safely released or dumped. The shock absorber should meet military standards for vibration, shock, electromagnetic interference, and environmental factors. It should also be operable in industrial and marine environments. The shock absorber should fit within a compressed space of 23 in. by 23 in. by 109 in. and have a stroke no greater than 9 ft. The weight, including supports, should not exceed 10,500 lb. The shock absorber should be adjustable to provide a force from 0 lbf to 250,000 lbf and be controllable/programmable to provide a force from 0 lb. to 35,000 lb. It should have a minimum of 3 settings and be capable of adjusting its setting within 5 seconds. The shock absorber should operate within a temperature range of -13°F to 149°F and withstand a storage temperature range of -27°F to 160°F. It should be capable of supporting a cyclic operation of at least 500,000 cycles within a 25-year life without failure in fatigue. The shock absorber should also be capable of monitoring and providing real-time information on stroke position and system conditions. The project will be conducted in three phases: Phase I involves designing and developing a concept, Phase II involves building a prototype, and Phase III involves fabricating a full-scale working adjustable shock absorber. The technology has potential applications in various mechanical systems, including hydraulic and pneumatic control systems.

DOD SBIR 24.4 Annual - Biomaterial Energy Dissipating Structures (BEDS)
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "Biomaterial Energy Dissipating Structures (BEDS)" as part of the SBIR program. The Defense Advanced Research Projects Agency (DARPA) is specifically interested in developing novel energy-dissipating biomaterial structures to enhance materiel and equipment airdrop capabilities. The current technology, which uses honeycomb cardboard pads, has limitations that can reduce the effectiveness of airdropped equipment. DARPA is looking for new biomaterial structures that can dissipate high levels of energy per unit mass and meet specific performance metrics. The structures must be at least 98wt% wood or other biodegradable plant-based material, have low projected costs for full-scale production, and pass various dynamic crushing stress and rebound energy tests. The project will be conducted in two phases, with Phase I focusing on achieving the specified mechanical properties of the structures within a six-month timeframe. Phase II will involve scale-up and mechanical properties testing, with the option for further scale-up and mass production in Phase II Option I. The ultimate goal is to develop energy-dissipating structures that can be used not only in airdropped materiel protection but also in various commercial applications such as truck trailers, shipping containers, packaging material, and building material for temporary structures. The solicitation is currently open, and the application due date is March 31, 2025.

DOD SBIR 24.4 Annual - Multilayer Waveguide Optical Gyroscope
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of a high-end tactical miniature optical waveguide gyroscope for future U.S. Army missions. The current inertial navigation systems used by the Army are large and expensive, and smaller alternatives such as Micro-Electro-Mechanical (MEMS)-based sensors do not meet the Army's requirements for cost, accuracy, stability, and survivability. The goal is to develop a low-cost and lightweight 6-axis Inertial Measurement Unit (IMU) with high-tactical performance. The desired performance includes a gyro bias stability of 0.2 degrees/hour, scale factor error less than 50 ppm, and angular random walk less than 0.05 degree/root-hour. The gyroscope should also have a high bandwidth, high dynamic range, and low sensitivity to extreme shock and vibration environments. The solicitation focuses on the feasibility of new optical waveguide gyroscope technologies, such as the integrated Silicon waveguide Optical Gyroscope (iSOG). The Phase I of the project involves proving the feasibility of a multi-level waveguide optical sensor coil, while Phase II focuses on designing and delivering a prototype waveguide optical gyroscope. The final phase aims to develop an Inertial Sensor Assembly (ISA) consisting of three gyros and three accelerometers. The technology has potential applications in commercial IMUs and military autonomous modular payloads. The project is open for proposals until March 31, 2025.

DOD SBIR 24.4 Annual - YTC Full Load Cooling
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic "YTC Full Load Cooling" as part of their SBIR 24.4 Annual solicitation. The objective of this research is to develop modernized data processing techniques to accurately assess the cooling capabilities of military vehicles with electronically controlled powertrains. The current testing methodologies and data processing techniques for fluid temperature data in critical systems of military vehicles are outdated and cannot be used for assessing vehicles with electronically controlled transmissions. The goal is to modernize the test methodology and utilize synthetic data generation techniques to accurately characterize the performance of the vehicle, even in extreme environments. The Phase I of the project will involve an initial site visit, development of a new Full Load Cooling (FLC) test methodology, characterization of powertrain derating, and submission of a final report. Phase II will focus on refining the FLC test methodology, developing a software program and Graphical User Interface (GUI) for synthetic data generation, and creating a test plan for field conditions. The potential impacts of this research include improved testing and assessment of military vehicles' cooling system performance, better understanding of powertrain derating, and the development of advanced data processing techniques. The research will leverage commercial industry data and expertise on electronically controlled powertrains and can have applications in modeling and simulation capabilities for engine and energy cooling, as well as in the manufacturing process for cooling systems and powertrains. The project duration is from 4QFY24 to 3QFY26, and interested parties can find more information and submit proposals on the DOD SBIR website.

Department of Defense
The Department of Defense (DOD) is seeking proposals for a solid-state scalable/tileable imaging detector for high-energy neutron radiography. The objective is to deliver a state-of-the-art high-energy neutron radiography imaging/detector. The technology will be used in conjunction with a source of high-energy neutrons to achieve a state-of-the-art neutron radiography system. The project will consist of three phases.

In Phase II, the proposer will build and deliver a tiled detector with minimum dimensions of 11" square that is effective for 1 MeV neutrons. The detector should provide short acquisition imaging times, high contrast, high spatial resolution, and high signal-to-noise ratio. In Phase III, the proposer will explore dual-use applications of the technology. Potential applications include accurate and fast inspections of Army ammunition, armaments, and other products for quality, safety, and lethality. The technology could also be used for compact, lightweight, self-contained scalable detectors in the detection of materials that emit gamma/beta rays or sub-atomic particles, such as radioactive isotopes, contamination, and special nuclear material. Commercial applications could include ground stationary check points, aerial applications, and underground/underwater drilling/mining applications. The project duration is not specified, but the proposal submission deadline is March 31, 2025.
