AeroAstro Research Labs

The Aerospace Controls Laboratory investigates estimation and control systems for modern aerospace systems, with particular attention to distributed, multivehicle architectures. Example applications involve cooperating teams of unmanned aerial vehicles or formation-flying spacecraft. The research goal is to increase the level of systems' autonomy by incorporating higher-level decisions, such as vehicle-waypoint assignment and collision avoidance routing, into feedback control systems. Core competencies include optimal estimation and control, optimization for path-planning and operations research, receding-horizon/model predictive control, and GPS.

The Communications and Networking Research Group's primary goal is the design of network architectures that are cost effective, scalable, and meet emerging needs for high data-rate and reliable communications. To meet emerging critical needs for military communications, space exploration, and internet access for remote and mobile users, future aerospace networks will depend upon satellite, wireless and optical components. Satellite networks are essential for providing access to remote locations lacking in communications infrastructure; wireless networks are needed for communication between untethered nodes, such as autonomous air vehicles; and optical networks are critical to the network backbone and in high performance local area networks.

The Laboratory for Aviation and the Environment addresses a major challenge facing the aviation industry today: understanding and reducing aviation’s environmental impacts. The lab advances our knowledge of how aviation impacts the environment and collaboratively develops mitigation strategies.

Current research thrusts are:

• Evaluating the climate and air quality impacts of aircraft emissions. This includes quantifying the impact of airport emissions on near-airport air quality, aircraft cruise emissions on global air quality, and contrails on regional climate.
• Developing tools to enable designers, policymakers, and researchers to evaluate policy and design decision’s environmental implications, including a quantitative understanding of uncertainty. These tools are used to inform international policy negotiations.
• Environmentally optimizing both ground and en route operations. Examples include developing and testing procedures for minimizing ground fuel burn, computing the air quality impacts of controller decisions in real-time, and developing metrics for the environmental performance of aircraft.
• Assessing potential alternative jet fuels that can reduce adverse climate and air quality impacts. This involves assessing the lifecycle environmental impacts of alternative fuel production and use, as well as broader environmental and economic implications..

The Man Vehicle Laboratory optimizes human-vehicle system safety and effectiveness by improving understanding of human physiological and cognitive capabilities, and developing appropriate countermeasures and evidence-based engineering design criteria.

The increasingly complex systems we are building today enable us to accomplish tasks that were previously difficult or impossible. At the same time, they have changed the nature of accidents and increased the potential to harm not only life today but also future generations. Traditional system safety engineering approaches, which started in the missile defense systems of the 1950s, are being challenged by the introduction of new technology and the increasing complexity of the systems we are attempting to build. Software is changing the causes of accidents and the humans operating these systems have a much more difficult job than simply following pre-defined procedures.  We can no longer effectively separate engineering design from human factors and from the social and organizational system in which our systems are designed and operated.

The goal of the Laboratory for Systems Safety Research is to create new tools and processes that will allow us to engineer a safer world. Engineering safer systems requires multi-disciplinary and collaborative research based on sound system engineering principles, that is, it requires a holistic systems approach. LSSR has participants from multiple engineering disciplines and MIT schools as well as collaborators at other universities and in other countries. Current students are working on safety in aviation (aircraft and air transportation systems), spacecraft, medical devices and healthcare, automobiles, railroads, nuclear power, defense systems, energy, and large manufacturing/process facilities. Cross-discipline topics include:

• Hazard analysis
• Accident causality analysis and accident investigation
• Safety-guided design
• Human factors and safety
• Integrating safety into the system engineering process
• Identifying leading indicators of increasing risk
• Certification, regulation, and standards
• The role of culture, social, and legal systems on safety

The Technology Laboratory for Advanced Materials and Structures (TELAMS), known since its establishment as TELAC, has been dedicated to providing leadership in the advancement of the knowledge and capabilities of the composites and structures community through education of students, original research, and interaction with the community at large. This leadership continues today at TELAMS, with an emphasis on composite materials, as the research topics span a wide spectrum, from basic understanding of composite materials to their behavior in specific structural configurations, with the ultimate objective of gaining a sufficient understanding of the properties of a composite laminate's basic building block, and how these properties interact to determine properties of laminates and structures made of composite materials. Recently, the focus of the laboratory has broadened into other areas, and thus its renaming. These areas include multi-scale modeling and simulation of the mechanics of advanced materials used in the aerospace industry with emphasis on understanding the influence of micro-structural features of deformation and failure in their effective engineering response, computational modeling in solid mechanics and fluid-structure interaction problems, and design, fabrication, and testing of micro-electromechanical systems (MEMS), along with their associated materials and processes.
