Description: The rotary wing is a type of drone that uses rotating blades for lift, allowing it to take off and land vertically. This design is based on the principle of lift generated by the propellers, which spin at high speeds to create a pressure difference between the upper and lower parts of the blades. Rotary wings are characteristic of multirotor drones, which can have anywhere from two to eight propellers, with the most common being four-propeller drones known as quadcopters. These drones are highly maneuverable and can hover in place, making them ideal for various applications. Additionally, their design allows for greater stability compared to fixed-wing drones, which require a minimum speed to stay airborne. The versatility of rotary wings has led to their adoption in multiple sectors, from aerial photography to package delivery, and their popularity has grown exponentially in recent years, driven by advances in battery technology and control systems. In summary, the rotary wing represents a significant innovation in the field of drones, combining efficiency, maneuverability, and ease of use.
History: The concept of rotary wings dates back to the early 20th century when the first helicopters began to be developed. However, the use of rotary-wing drones became popular starting in the 2000s, with advancements in battery technology and control systems. In 2006, the launch of consumer drone models, such as the Parrot AR.Drone, marked a milestone in the accessibility of these devices for the general public.
Uses: Rotary-wing drones are used in a variety of applications, including aerial photography, infrastructure inspection, environmental monitoring, package delivery, and in the military for reconnaissance and surveillance. Their ability to fly in confined spaces and ease of use make them ideal for tasks that require precision and flexibility.
Examples: A notable example of a rotary-wing drone is the DJI Phantom, which has been widely used by photographers and filmmakers. Another example is Amazon’s delivery drone, which uses rotary wing technology to efficiently transport packages to customers.
