Navigating Regulatory Compliance for UAV Electronics Development

Unmanned Aerial Vehicles (UAV) deliver sophisticated capabilities with tremendous cost advantage over traditional methods. While this technology has evolved from military missions, civil and commercial sectors are beginning to realize many of the same remote sensing benefits. However, one of the main barriers to rapid full-scale commercial growth is the concern for safety. As a myriad of certification agencies scramble to keep up with the unique demands of this fast-growing industry, one thing is clear – where applicable, pertinent certification standards for manned aircraft are starting to apply. For the complex electronics that provide the brains of these systems, this means a swift move towards compliance with DO-178C for software and DO-254 for hardware development.

Simulating Lightweight Vehicles Operating on Discrete Terrain

Engineers increasingly rely on simulation to augment and, in some cases, replace costly and time consuming experimental work. However, current simulation capabilities are sometimes inadequate to capture phenomena of interest.

UUV Developments for Defense and Commercial Applications

Autonomous Undersea Vehicles (AUVs), also commonly referred to as Unmanned Undersea Vehicles (UUVs), have a history dating back to 1957 with the Special Purpose Underwater Research Vehicle (SPURV) developed by the University of Washington's Applied Physics Laboratory. Academia and special government programs drove the early decades of research but advancements were slow. Throughout the 1960s, 1970s, and 1980s, more explosive growth came for the Remotely Operated Undersea Vehicle (ROV) market which had two primary advantages: they were operated via a tether that provided power for the vehicle and man-in-the-loop control.

The Evolution of Tactical Robots

The lessons of yesterday and today are driving tomorrow’s robotic programs.

A revolution in Unmanned Ground Vehicles (UGVs) is taking place today that focuses on formalizing the permanent integration of ground robots into military organizations within the U.S. Department of Defense and other nations’ military forces as well. Similar activities are likewise cementing the relationship of UGVs to first responder organizations as ground robots continue to prove that they save lives.

Next-Generation Antenna Design

Materials and Processes Enable New Possibilities for Unmanned Systems Command & Control

Unmanned vehicles are finding increasing usage in military engagements, not only for aerial applications but also for ground and underwater missions. Modern antenna designs can increase unmanned vehicle fuel efficiency through reduced antenna size, increased antenna conformality, and reduced antenna weight. For airborne UAVs, time on station is a critical mission parameter directly influenced by payload weight and aerodynamics. For unmanned ground vehicles, increased antenna conformality reduces the likelihood of accidental damage that occurs with externally protruding antennas.

Supervisory Control State Diagrams to Depict Autonomous Activity

The military seeks to enable agile and adaptive mission management and control for a team comprised of unmanned aerial vehicles (UAVs), unattended ground sensors (UGS), dismounted war-fighters with mobile control stations, and an operator located in a central control station. With UAVs equipped and authorized to re-plan and act without human input, the challenge is developing methods for a human operator to sufficiently monitor, inspect, and manipulate the UAVs’ activities, which include goal-directed task selection, situation assessment, decision-making, planning, and actions.

Aerodynamic Modeling of a Flapping Wing Unmanned Aerial Vehicle

The phenomenon of flapping wing flight in nature has been studied for centuries. Recently, flapping flight for unmanned aerial vehicle (UAV) applications has become of interest. Flapping wing flight offers many potential advantages over traditional fixed- and rotary-wing aircraft. Fixed-wing UAVs have the advantages of long range and endurance, and high payload capabilities; however, they require high forward flight speeds and most configurations cannot hover, which makes them difficult to control in confined spaces.
