“…Although winglets are helpful during the takeoff phase of the flight where the induced drag is the dominant drag force, they can be detrimental to the performance of the aircraft during cruise flight. In a study conducted by Meyran et al (2021), they showed the drag generated for different winglet cant angle configuration for the winglet of Bombardier's CRJ-700 [10]. Unsurprisingly, the least amount of drag and the greatest amount of lift were observed when the cant angle was 0°at 0°angle of attack [10].…”

“…It has been proven in multiple studies that the morphing wing can improve the lift-to-drag ratio, expand the flight envelope, and increase the maneuverability of the aircraft [9]. Adapted from morphing wing technology, the morphing winglets have also gained popularity in recent times since the conventional winglet represents an additional structure at the tip of the wing which increases the profile drag [10]. The morphing winglet is theoretically able to change shape during flight by altering its cant, sweep, and toe angles.…”

Unsurprisingly, the least amount of drag and the greatest amount of lift were observed when the cant angle was 0°at 0°angle of attack [10]. With morphing technology, the winglet's cant angle can be changed to 0°during cruise flight which will significantly lower the drag of an aircraft that utilizes a winglet.…”

<p>This thesis report presents a structural and vibrational analysis experiment of a wing model with morphing winglets. It details the theory behind Aeroelasticity and its importance to the aircraft’s structural integrity. It provides methods to validate the structural integrity and performance of the wing which will allow engineers to optimize the wing design. The experiment was developed and designed by undergraduate thesis students in collaboration with the faculty of the Aerospace Department at Toronto Metropolitan University. The wing model of the wing was created based on the dimensions obtained for the wind tunnel at Toronto Metropolitan University. The wing was designed to have a locking mechanism that allows the morphing winglets at various cant angles to attach safely and firmly onto the wing. After creating the CAD models of the wing with morphing winglets at 15°, 25°, 35°, and 45° on a popular design software known as Solidworks, the static structural and vibrational analysis were conducted on ANSYS Workbench. Using vibrational analysis, the first 6 mode shapes of the model were determined. It was found that the natural frequency of the wing with morphing winglets was around 29 Hz for the various cant angle configurations. An analytical solution was also obtained on MATLAB through several iterations. The flutter speed of the analytical solution was found to be 57.65 m/s. Through the principle of damping extrapolation, the natural frequency of the analytical solution was found to be 33.2 Hz which was similar to the theoretical results. For further study in this undergraduate thesis, the next steps involve manufacturing the wing and conducting the Ground Vibration Test (GVT) and the wind tunnel test on the model to determine the frequency of vibration, mode shapes, and damping ratios.</p>

In a previous paper, the authors dealt with the current showstoppers that inhibit commercial applicability of morphing systems. In this work, the authors express a critical vision of the current status of the proposed architectures and the needs that should be accomplished to make them viable for installation onboard of commercial aircraft. The distinction is essential because military and civil issues and necessities are very different, and both the solutions and difficulties to be overcome are widely diverse. Yet, still remaining in the civil segment, there can be other differences, depending on the size of the aircraft, from large jets to commuters or general aviation, which are classifiable in tourism, acrobatic, ultralight, and so on, each with their own peculiarities. Therefore, the paper aims to trace a common technology denominator, if possible, and envisage a future perspective of actual applications.
