The Aerospace Computational Design Lab's mission is to improve the design of aerospace systems through the advancement of computational methods and tools that incorporate multidisciplinary analysis and optimization, probabilistic and robust design techniques, and next-generation computational fluid dynamics. The laboratory studies a broad range of topics that focus on the design of aircraft and aircraft engines.
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 UAVs or formation-flying spacecraft. The research goal is to increase the level of autonomy in these systems 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 Aerospace Robotics and Embedded Systems group’s mission is the development of theoretical foundations and practical algorithms for real-time control of large-scale systems of vehicles and mobile robots. Application examples range from UAVs and autonomous cars, to air traffic control, and urban mobility.The group researches advanced algorithmic approaches to control high-dimensional, fast, and uncertain dynamical systems subject to stringent safety requirements in a rapidly changing environment. An emphasis is placed on the development of rigorous analysis, synthesis, and verification tools to ensure the correctness of the design. The research approach combines expertise in control theory, robotics, optimization, queueing theory and stochastic systems, with randomized and distributed algorithms, formal languages, machine learning, and game theory.
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 group is working on a wide range of projects in the area of communication networks and systems, with application to satellite, wireless, and optical systems. In recent years, the group has been developing efficient network control algorithms for heterogeneous wireless networks. Existing wireless networks are almost exclusively confined to single hop access, as provided by cellular telephony or wireless LANs. While multi-hop wireless networks can be deployed, current protocols typically result in extremely poor performance for even moderate sized networks. Wireless Mesh Networks have emerged as a solution for providing last-mile Internet access. However, hindering their success is our relative lack of understanding of how to effectively control wireless networks, especially in the context of advanced physical layer models, realistic models for channel interference, distributed operations, and interface with the wired infrastructure (e.g., internet). CNRG has been developing effective and practical network control algorithms that make efficient use of wireless resources through the joint design of topology adaptation, network layer routing, link layer scheduling, and physical layer power, channel, and rate control.
Robust network design has been another exciting area of recent pioneering research by the group. In particular, the group has been developing a new paradigm for the design of highly robust networks that can survive a massive disruption that may result from natural disasters or intentional attack. The work examines the impact of large-scale failures on network survivability and design, with a focus on interdependencies between different networked infrastructures, such as telecommunication networks, social networks, and the power grid. The group’s research crosses disciplinary boundaries by combining techniques from network optimization, queueing theory, graph theory, network protocols and algorithms, hardware design, and physical layer communications.

GTL also has unique computational and theoretical modeling capabilities in the areas of gas turbine fluid mechanics, turbomachinery, and aero-acoustics.
Research in the Humans and Automation Lab focuses on the multifaceted interactions of human and computer decision-making in complex sociotechnical systems. With the explosion of automated technology, the need for humans as supervisors of complex automatic control systems has replaced the need for humans in direct manual control. A consequence of complex, highly automated domains in which the human decision-maker is more on-the-loop than in-the-loop is that the level of required cognition has moved from that of well-rehearsed skill execution and rule following, to higher, more abstract levels of knowledge synthesis, judgment, and reasoning. Employing human-centered design principles to human supervisory control problems, and identifying ways in which humans and computers can leverage the strengths of each other to achieve superior decisions together is HAL's central focus. Current research projects include collaborative human-computer decision making for command and control domains, and investigating human understanding of complex optimization algorithms and visualization of cost (objective functions); uses of adaptive automation and psychophysiologic measures in human supervisory control; decision theoretic modelling for datalink communications; developing metrics for evaluating display complexity; and display design for autonomous formation flying.

The Space Propulsion Laboratory, part of the Space Systems Lab, studies and develops systems for increasing performance and reducing costs of space propulsion. A major area of interest to lab is electric propulsion, in which the electrical, rather than chemical energy propels spacecraft. The benefits are numerous and very important, that is the reason why many communication satellites and scientific missions are turning to electric propulsion systems. In the future these plasma engines will allow people to do such things as explore in more detail the structure of the universe, increase the lifetime of commercial payloads or look for signs of life in far away places. Other areas of research include microfabrication; numerical simulation, numerical simulation, Hall thrusters, space tethers, orbit optimization, spacecraft-thruster interactions and plasma waves emission and propagation.
The Space Systems Laboratory engages in cutting-edge research projects with the goal of directly contributing to the current and future exploration and development of space.

The Systems Engineering Advancement Research Initiative (SEAri) advances the theories, methods, and effective practice of systems engineering applied to complex socio-technical systems through collaborative research. Four key areas of research are: 1) Socio-Technical Decision Making, which seeks to develop multi-disciplinary representations, analysis methods, and techniques for improving decision making for socio-technical systems; 2) Designing for Value Robustness, which seeks to develop methods for concept exploration, architecting and design using a dynamic perspective for the purpose of realizing systems, products, and services that deliver sustained value to stakeholders in a changing world; 3) Systems Engineering Economics, which seeks to develop an economics view of systems engineering to achieve measurable and predictable outcomes while delivering value to stakeholders; 4) Systems Engineering in the Enterprise, which involves empirical studies and case-based research for the purpose of understanding how to achieve more effective systems engineering practice taking into account the nature of the system being developed, external context, and the characteristics of the associated enterprise.
The research group has a strong foundation in the aerospace system design and architecture domain, with more recent work branching into the transportation and infrastructure systems domains. While these domains represent past work and ongoing areas for case study analysis, the methods and practices developed by SEAri aim for cross-domain applicability.
The System Architecture Lab studies the early-stage technical decisions that will determine the majority of the system's performance. SAL has helped architect systems from earth observation networks, to lunar surface exploration vehicles. The lab’s key contention is that by identifying the most important initial technical decisions and exhaustively enumerating their options, the best potential designs are identified prior to the detailed design activities. SAL work stands in contrast to a traditional trade-study perspective, where two to four points designs are compared, without reference to the intervening options or to a fully explored tradespace. The emerging field of System Architecture aims to understand what patterns emerge across disparate domains, to gain an understanding of the making of good architecture. System architecture models look broadly across possible technologies, subsystems, and use contexts. Although each model employs problem-specific parametrics, SAL has advanced the state of the art by developing unique and generalizable approach to structuring complex systems architecting problems that can be applied across disciplines.
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
- dentifying 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.
