    DARPA Announces Microsystems Exploration Program

    Over the past few decades, DARPA's Microsystems Technology Office (MTO) has enabled revolutionary advances in electronics materials, devices, and systems, which have provided the United States with unique defense and economic advantages. To continue its path of successful electronics innovation, DARPA today announced a new MTO effort called the Microsystems Exploration program. The Microsystems Exploration program will constitute a series of short-term investments into high-risk, high-reward research focused on technical domains relevant to MTO. Leveraging streamlined contracting and funding approaches, awards for each area of exploration – or μE topic – will be made within 90 days of announcement. Each μE topic will run for up to 18 months, during which time researchers will work to establish the feasibility of new concepts or technologies. “This strategy of making smaller, targeted research investments will allow us to capitalize quickly on new opportunities and innovative research concepts,” said Dr. Mark Rosker, director of MTO. “The Microsystems Exploration program provides a way to assess whether or not a concept could evolve into a full program without requiring the use of more significant resources.” The Microsystems Exploration program will employ best practices from DARPA's other fast-track solicitation programs – the agency-wide AI Exploration program and the Defense Science Office's “Disruptioneering” initiative. These programs are focused on enabling rapid advances in artificial intelligence and basic science respectively, and have shown numerous benefits to this approach. Similar to these efforts, the simplified proposal, contracting, and funding process employed by each μE topic will make it even easier for individuals and organizations to contribute to DARPA's mission. Each award may be worth up to $1 million, as described in the individual μE solicitations. To help advance MTO's strategic imperatives, the Microsystems Exploration program will pursue innovative research concepts that explore frontiers in embedded microsystem intelligence and localized processing; novel electromagnetic components and technologies; microsystem integration for functional density and security; and disruptive microsystem applications in C4ISR, electronic warfare, and directed energy. In alignment with these technical domains, the first three potential topics focus on hardware security, novel materials, and new computing architectures for heterogeneous systems. The first potential topic aims to address security issues within the hardware supply chain. Defense systems increasingly rely on commercial of the shelf (COTS) devices that move through complex supply chains, with each component changing hands several times. Throughout the process, nefarious actors have numerous opportunities to compromise the technology by introducing malicious circuitry – or hardware Trojans – to printed circuit boards (PCBs). The ability to detect when components are tampered with is difficult as the attacks are designed to remain hidden and avoid post-manufacturing tests until its functionality is triggered. The “Board-Level Hardware Security” related topic could explore the technological feasibility for real-time detection against these hardware Trojans installed in complex COTS circuit boards. New uses of scandium (Sc)-doped aluminium nitride (AIN) could be investigated as a future potential μE topic. Sc-doped AlN is a popular material for a number of device applications, which span RF filters, ultrasonic sensors, and oscillators. Recent work has demonstrated the emergence of the material's use in ferroelectric switching, which has enormous potential across a number of applications and devices. However, current exploration of this capability has been limited to a research setting. The “Ferroelectric Nitride Materials and Non-Volatile Memory” related topic could expand on this research, identifying the thickness and doping ranges that exhibit ferroelectric behavior, the robustness and reproducibility of the ferroelectric response, and further demonstrating ferroelectric nitrides as a technologically useful material. Another potential μE topic could seek to address the trade-off between programmer productivity and performance that happens as hardware complexity continues to skyrocket. Advances at the hardware and software level that have enabled continued progress in computing performance, cost, and ubiquity have hit a wall. The expectation is that subsequent performance gains will come from an increased level of parallelism, specialization, and system heterogeneity, which will place further strain on programmer productivity. This “Massively Parallel Heterogeneous Computing” related topic could explore the creation of compiler technology that improves programmer productivity of massively parallel and heterogeneous processing systems. Additional information about the Microsystems Exploration program can be found under Program Announcement DARPA-PA-19-04. Further details on the three potential μE topics can be found under Special Notice DARPA-SN-19-69. The Microsystems Exploration Research Area Announcement Special Notice has been issued solely for information and potential new program planning purposes. All future and official solicitation notices for μE topics will be published to Federal Business Opportunities (FBO) at www.fbo.gov. https://www.darpa.mil/news-events/2019-07-16

    GE Sees Military as Driving Next-Gen Technology

    John Morris PARIS - “Military is where the commercial business was 10 years ago,” says GE Aviation president and GEvice chairman David Joyce. With commercial now set after a decade of renewal (the CF6 replaced by the GEnx, GE90 by GE9X, CFM56 by Leap, CF34 by Passport, and the emergence of the Catalyst turboprop engine), hundreds of engineers and research and development resources are being tasked with creating future generations of military powerplants. Now that the commercial side has proved that new materials such as ceramic matrix composites and technologies such as additive manufacturing are viable, affordable and producible, the military has the confidence to lead the march into new territory. Technologies developed for commercial engines have enabled new military capabilities; in turn, military research and development will enable even newer commercial engines decades into the future. It's a virtuous cycle, Joyce explains. GE is on a roll: it has won the U.S. Army's ITEP competition to replace all T700 engines in Black Hawk and Apache helicopters with the ultra-fuel-efficient single-shaft ITEP next-gen helicopter engine, and it won contracts worth a billion dollars to develop its AETD three-stream adaptable fighter engine as far as demonstrating it on the ground in an F-35. Flight tests could follow, as could eventual reengining of the F-35 fleet. But in any case, GE will be ready with an engine for sixth-generation fighters. In addition, the ubiquitous F404/F414 is being upgraded and continues to win new competitions, including the USAF's new Boeing-Saab T-X trainer and several foreign future fighter programs; the T408 turboshaft powers the new Sikorsky CH-53K King Stallion; and a team is working full time on competing to reengine the B-52 bomber. Business is growing “at really good rates” on both manned and unmanned “black” programs, says Joyce, and hybrid electric is being studied for future applications including UAVs, he adds. He believes GE already has the enabling technologies for the next decade, “but industrializing them is a different thing.” The company has already invested “billions of dollars” in developing a manufacturing and supply chain of materials and technologies for its commercial engines, and this will continue, “Additive manufacturing may be the most disruptive technology that I've seen in the industry in a long time,” says Joyce, “as it opens up a space for designers and for manufacturing that is on a different dimensional plane. It takes a long time to learn how to design with additive. It takes even longer to learn how to manufacture with additive at speed and high rate from a quality standpoint of view. “We are jumping in with both feet because the results on the back end when you get it right are extraordinary,” he adds. “It's going to pay off a whole load more in the next 20 years. This is going to be the best [real return on investment] that we've ever done.” https://aviationweek.com/paris-airshow-2019/ge-sees-military-driving-next-gen-technology
