Morphing is also defined as a set of technology that increases a vehicle performance by manipulating certain characteristics to match the aircraft state to the environment and current mission. Such wing concept has big potential to improvise the aircraft performance for multiple mission flight. Based on previous studies, there are several geometrical parameters that produce morphing wings, each of these morphing concepts has particular influence on of the aircraft's aerodynamics. Our morphing wing is based on the bio-mimicry of the bird's wing with stages delivered based on different configurations of the fight conditions such as take-off, landing, cruise, and also extreme weather conditions. It is both span and cord-wise expanding and contrasting mechanics which match the actual bird feather and wing moment. Morphing is originated from meta-morphose word.

Detailed Description of the Invention
The morphing wing developed by our team is inspired by the design and functionality of bird wings. The design of the wing is based on the principle of bio-mimicry, where the structure and mechanics of the wing are modeled after the natural movements and features of a bird's wing. The wing is equipped with a system that allows it to change its shape in real-time, adapting to different flight conditions and weather conditions. This includes take-off, landing, cruise, and extreme weather conditions such as turbulence and heavy wind. The morphing wing is capable of both span-wise and chord-wise expansion and contraction, mirroring the way that a bird's feathers and wing move in response to the conditions. This innovative design provides improved efficiency, stability, and control for the aircraft, making it possible to fly in a wider range of conditions with enhanced performance.
This morphing wing technology includes a pre-installed servo mechanism at the junction points of the wing sections. This mechanism allows the wing to extend and contract in response to the commands given by the pilot or by the computer system that is connected to the servo mechanism. The servo mechanism is designed to provide quick and precise control of the wing shape, allowing it to change its configuration in real-time. To ensure that the wing operates as intended, our team conducted a series of structure and flow analyses at different angles and in different wind conditions. These analyses helped to validate the design and optimize the performance of the wing, ensuring that it can handle the demands of various flight conditions and weather conditions. By incorporating the servo mechanism and conducting these analyses, the morphing wing technology delivers enhanced efficiency, stability, and control for the aircraft, making it possible to fly in a wider range of conditions with improved performance.
The wing undergoes a two-stage morphing process, with all stages (1e and 1f) linked to the continuous structure (1a). The extent of morphing in each stage ranges from zero to 180 degrees, as depicted in Figure 1. Second stage morphing (1c) is attached to the actuator assembly (2)and the actuator assembly is connected to the first stage morphing mechanism figure(1).The morphing mechanism (1d) for the second stage is connected to the end of the first stage figure (1).Rib (1a) of the wing carry through structure is assembled to the fuselage (3) of uav.The angle can be changed by using actuator connected to the mechanism figure 1.One end of the actuator (2) is connected to the stage (1c) as shown in the figure(1) The isometric view of the actuator used in the morphing wing is shown in figure2.Morphing wing is attached to the fuselage (3) and empennage (4, 5) also connected to the rear fuselage as shown in the figure(4).The morphing wing provides better aerodynamic efficiency figure(3) compared to the conventional wing structure. The morphing mechanism is used to change the morphing angles at different flight speeds. Morphing wing (1) used to provide stability and control of uav.The mechanism facilitates span wise extension and retraction of the wing in two stages
In the design of our morphing wing technology, we have taken a structural approach that leverages the use of smart and flexible materials for the wing frame and wing box. This choice was made to ensure that the wing can withstand both structural and air loads, while still being able to change its shape and move in response to the commands from the pilot or computer system. To achieve this balance of strength and flexibility, we have utilized carbon fiber to a significant extent in the construction of the wing. The use of carbon fiber provides a high level of tensile strength, allowing the wing to flex and bend as needed while maintaining its structural integrity. Through extensive experimentation, we have confirmed that this material choice enables the wing to meet the demands of the various flight conditions and weather conditions it will encounter. In conclusion, our use of smart flexible materials and the extensive experimentation we have conducted have enabled us to create a morphing wing structure that is both strong and adaptable, delivering improved performance for the aircraft.
To aid in the understanding and further development of the morphing wing technology, a pre-assembled model has been created using 3D printing technology. This model serves as a representation of the wing and its various components, allowing for a better understanding of the design and its functionality. Additionally, this model provides a platform for conducting experimental aerodynamics studies to validate the design and improve the performance of the wing. The 3D printed model provides a clear and quick way to visualize the various components of the morphing wing, allowing for more effective collaboration and communication between team members and stakeholders. This model is an important tool for advancing the development of the morphing wing technology, helping to bring it closer to implementation in practical applications. In conclusion, the 3D printed model provides a valuable resource for understanding and experimenting with the morphing wing, and serves as a crucial step in its development and advancement.
The primary objective of our morphing wing project was to design and build a wing structure that would be strong, yet flexible, so that the wing could change its shape without suffering any damage to its structure, both while stationary and in flight. The goal was to create a wing that could morph in response to the commands from the pilot or computer system, yet still maintain its structural integrity and performance. To achieve this, careful consideration was given to the choice of materials and the design of the wing frame and wing box, ensuring that it would have the necessary strength to withstand the various loads it would encounter in flight, while also being flexible enough to change its shape. Through extensive experimentation and analysis, we have confirmed that our design meets these requirements, delivering a wing that is capable of morphing with ease, while maintaining its structural stability and performance. In conclusion, our main target was to build a morphing wing that could deliver improved performance and efficiency, while also being structurally sound and safe.
