“…Based on user's input parameters, a generic UAV is dynamically displayed in the display area. The first pair of tools in the app are the "Matching Plot" [29,30] and the "Constraint Diagram" [31], which enable selection of the required wing loading and power loading. The "Tail Sizing" tool aids in selecting the geometric parameters of the tail's vertical and horizontal stabilizers based on the selected wing and fuselage parameters.…”

“…The design process began by determining the required wing area and motor size using the matching plot and the constraint diagram. Both techniques use the weight of the UAV as the main parameter and are used to size the wing and engine [29][30][31]. The design point in both techniques determines the necessary wing area and required power.…”

Design and Analysis of MataMorph-3: A Fully Morphing UAV with Camber-Morphing Wings and Tail Stabilizers

et al. 2022

Conventional aircraft use discrete flight control surfaces to maneuver during flight. The gaps and discontinuities of these control surfaces generate drag, which degrades aerodynamic and power efficiencies. Morphing technology aims to replace conventional wings with advanced wings that can change their shape to control the aircraft with the minimum possible induced drag. This paper presents MataMorph-3, a fully morphing unmanned aerial vehicle (UAV) with camber-morphing wings and tail stabilizers. Although previous research has presented successful designs for camber-morphing wing core mechanisms, skin designs suffered from wrinkling, warping, or sagging problems that result in reduced reliability and aerodynamic efficiency. The wing and tail stabilizers of MataMorph-3 feature hybrid ribs with solid leading-edge sections that house servomotors, and compliant trailing-edge sections with integrated flexible ribbons that are connected to the servomotors to camber-morph the ribs. Thin laminated carbon fiber composite skin slides smoothly over the compliant rib sections upon morphing, guided by innovative trailing-edge sliders and skin-supporting linkage mechanisms strategically located between the ribs. Sample prototypes were built and tested to show the effectiveness of the proposed design solutions in enabling smooth camber-morphing. The proposed design provides a better alternative to stretchable skins in morphing airplane designs through the concept of skin sliding.

“…From the other side, the rudder is a distance control tool which is similar to the elevator, while the aileron is a speed control tool. Thus, the sizing elementals of elevator and rudder are the same, but usually, the elevator sizing is much easier [1]. However, the aircraft rudder is served to solve six major conditions which are: turn coordinate, crosswind landing, asymmetric thrust balancing, spin recovery, adverse yaw, and adjustment of a glide slope.…”

“…Typical values for conventional aircraft are: chord (Cr/Cv) = 0.15-0.4, span (br/bv) = 0.7-1.0, area (Sr/Sv) = 0.15-0.3, and maximum deflection (±30 deg.) [1].…”

“…The primary surfaces include aileron, elevator, and rudder. These are employed for lateral, longitudinal, and directional control, respectively, and also have a high impact on lateral, longitudinal, and directional trim of the aircraft [1]. As a general rule, Dave Wyatt from Lockheed-Ft. Worth said that: "Having a Process to properly size the control power is essential to, optimize the configuration" [2].…”

Many aircraft design software packages are available in the market. Some of them are intended for preliminary design phase. These packages investigate the aircraft stability and controllability through the stability model to get the dimensional and non-dimensional derivatives. For students and fresh engineers, these derivatives are ambiguous and do not give a well-defined consideration about the influence of the control surface sizing on them.Therefore, adding the control surface model to preliminary software will assist, enhance, and improve students' knowledge, sympathy, and investigating studies. This paper presents the control surface model for use in preliminary aircraft design software. The model consists of three sub-models. Each sub-model is involved to perform the sizing of one of the primary conventional control surfaces. The aileron represents the first sub-model. The elevator represents the second sub-model, while the rudder represents the third sub-model. A flowchart for each sub-model is provided.

Applications and classifications of unmanned aerial vehicles: A literature review with focus on multi-rotors

During the past two decades, with the advancement of avionics, control systems, design, product methods, and communication systems, UAVs have gained more interest from both civil and military customers. Hence, more researchers have dedicated their time to developing new applications for drones and improving their performance. In this study, a literature review on drone applications is conducted. It is explained that they can be more effective and beneficial when merged with preexisting systems, and thus making a system of systems. Further, we have classified UAV applications more comprehensively. This classification can be very useful for providing insights when designing new UAVs. Finally, previous works are discussed thoroughly and diagrams are developed to show the research focus in this field. These statistical diagrams can also be used as a gap analysis tool.
