Engineers at Rutgers University are pioneering a new approach to drone flight by developing “solid-state” robotic birds that flap their wings without the use of traditional motors or gears. According to a recent press release from the university, the research team is utilizing smart materials driven by electricity to mimic and potentially exceed the natural flight mechanics of birds and insects.

The innovative design, detailed in a study published in Aerospace Science and Technology, replaces conventional electromagnetic motors with piezoelectric materials. These specialized materials change shape when exposed to an electrical voltage, allowing the drone’s wings to flex and twist dynamically.

This mechanism-free approach to ornithopters, drones that fly by flapping their wings, promises to deliver greater flexibility and control than standard propeller-driven drones. The Rutgers team believes these advancements could eventually make bird-like drones ideal for complex tasks such as urban package delivery, search and rescue operations, and environmental monitoring.

The Mechanics of Solid-State Flight

Replacing Motors with Smart Materials

Traditional experimental bird-like drones have largely relied on complex systems of motors, gears, and mechanical linkages to simulate the flapping motion of wings. However, these conventional actuators often struggle to match the continuous, fluid responsiveness of natural wings in changing air currents. The Rutgers researchers, led by Xin Shan and Onur Bilgen, an associate professor in the Department of Mechanical and Aerospace Engineering, have taken a simpler, more direct path.

Instead of using motors to act as muscles, the team applies thin strips known as Macro Fiber Composites (MFCs) directly onto flexible wings. When an electrical current flows through these strips, the entire wing structure morphs and flaps.

“We apply electricity to the piezoelectric materials, and they move the surface directly, without extra joints, extra linkages or motors,” Bilgen stated in the university’s press release.

Advantages Over Conventional Drones

The solid-state ornithopter design offers distinct advantages over traditional drones equipped with spinning propellers, particularly at smaller scales. Flapping wings are generally less destructive to themselves and their surroundings when they come into contact with obstacles, making them safer for navigating tight spaces around buildings, wires, and people.

Furthermore, the researchers note that the carbon fiber in their design acts similarly to feathers and bone, while the surface-mounted MFCs function like muscles and nerves. This biomimetic approach aims to achieve flapping flight without the need for complex, bone-like structures or muscle-like actuators.

Virtual Testing and Future Applications

Advanced Computer Modeling

To accelerate the development of these mechanism-free ornithopters, the Rutgers team created a comprehensive computer model that integrates the various physical forces involved in flight. This model accounts for wing and body motion, aerodynamics, electrical dynamics, and control architecture all at once.

By testing and optimizing designs virtually, engineers can save significant time and resources before building physical prototypes. This software-first approach allows the team to explore the feasibility of designs that rely on future material advancements.

“We’ve scientifically demonstrated that this type of ornithopter can be possible when we make certain material assumptions,” Bilgen explained in the release. “We can show the feasibility of designs that are not yet physically possible.”

Overcoming Material Limitations

Currently, the primary hurdle facing the widespread physical realization of these solid-state drones is the limitation of existing piezoelectric materials. The materials available today do not yet possess the capability required for optimal performance in these advanced designs. However, the mathematical models developed by the researchers provide a roadmap for future development as material science progresses.

Beyond aviation, the principles explored in this research could have broader implications for renewable energy. The team is investigating whether applying piezoelectric materials to wind turbine blades, which function essentially as rotating wings, could yield aerodynamic benefits by subtly altering the blade shape in real time to improve efficiency.

AirPro News analysis

The transition from rotary-wing drones to biomimetic ornithopters represents a significant leap in unmanned aerial vehicle (UAV) technology. While quadcopters dominate the current commercial market, their rigid propellers pose safety risks and efficiency limits in highly cluttered environments. We view the Rutgers research as a critical pivot toward solid-state actuation, which could drastically reduce the mechanical failure points inherent in gear-driven systems.

However, as the researchers acknowledge, the commercial viability of these bird-like drones hinges entirely on breakthroughs in material science. Until piezoelectric materials can deliver the necessary force and efficiency at scale, these solid-state ornithopters will likely remain confined to advanced computer simulations and early-stage laboratory prototypes.
