Introduction to Dr. Onur Bilgen
Dr. Bilgen is an associate professor at Rutgers University specializing in mechanical and aerospace engineering. His research focuses on advanced drone systems, including both fixed-wing and rotary-wing aircraft, as well as the use of smart materials in their design.
The concept of ornithopters
Ornithopters are synthetic flapping wing machines inspired by birds. They have the potential for unique flight capabilities and are finding their way into both research and commercial applications.
Role of smart materials
Smart materials, particularly piezoelectric materials, have unique properties that allow them to generate electricity when moved and vice versa. These materials can simplify drone designs by reducing the number of mechanical components, thereby lowering manufacturing and operational costs.
Efficiency of flapping wings
Flapping wing systems, while typically more complex than traditional rotary systems, can provide efficient aerodynamics and unique flight characteristics, particularly at smaller scales.
Technical challenges in research
The development of a comprehensive mathematical model to analyze ornithopter performance is a significant challenge, particularly concerning the leading edge vortex and its effects on flight dynamics.
Future applications of ornithopters
Ornithopters have promising applications in constrained environments like urban and indoor spaces. They may excel when lightweight and inexpensive solutions are needed for specific tasks.
Inspiration behind the research
Dr. Bilgen’s interest in flapping wing aircraft was sparked by safety concerns related to traditional rotating machinery. He aims to design aircraft that are simple, cost-effective, and can be easily produced.
Looking ahead in drone technology
The research focuses on developing lightweight, effective aircraft and further refining smart materials for drone applications. Continued exploration into leading-edge vortex modeling is essential for optimizing
