“…Therefore, designers have been striving to re-imagine the presentday aircraft by employing innovative technologies, such as adaptive morphing structures for flight optimisation and flow control [2][3][4]. The benefits and challenges of morphing structures are well documented in the literature [5,6] and various reviews have been produced [7,8]. In the aerospace sector, researches on morphing concepts are very wide and varied, ranging from concepts on fighter aircraft [9], regional aircraft [10,11], hovering micro air vehicles [12] and general aircraft [13,14].…”

This paper presents an unsteady flow analysis of a 3D wing with a morphing trailing edge flap (TEF) and a seamless side-edge transition between the morphed and static parts of a wing by introducing an unsteady parametrization method. First, a 3D steady Reynolds-averaged Navier–Stokes (RANS) analysis of a statically morphed TEF with seamless transition is performed and the results are compared with both a baseline clean wing and a wing with a traditional hinged flap configuration at a Reynolds number of 0.7 × 106 for a range of angles of attack (AoA), from 4° to 15°. This study extends some previous published work by examining the inherent unsteady 3D effects due to the presence of the seamless transition. It is found that in the pre-stall regime, the statically morphed wing produces a maximum of a 22% higher lift and a near constant drag reduction of 25% compared with the hinged flap wing, resulting in up to 40% enhancement in the aerodynamic efficiency (i.e., lift/drag ratio). Second, unsteady flow analysis of the dynamically morphing TEF with seamless flap side-edge transition is performed to provide further insights into the dynamic lift and drag forces during the flap motions at three pre-defined morphing frequencies of 4 Hz, 6 Hz, and 8 Hz, respectively. Results have shown that an initially large overshoot in the drag coefficient is observed due to unsteady flow effects induced by the dynamically morphing wing; the overshoot is proportional to the morphing frequency which indicates the need to account for dynamic morphing effects in the design phase of a morphing wing.

“…There are many previous study and research have been done to improve the aerodynamic efficiency of the wing by increasing the flexibility of the geometry and shape of the surface which is also known as the morphing wing, its ability to change the structural geometry adaptively can increase the aerodynamic efficiency of the aircraft [12]- [16]. Several previous studies conducted experiments and research to improve this morphing technology so that it can be implemented on full-scale aircraft wings [17]. Development and research are developed from various aspects such as the use of appropriate materials, structural design, mechanisms, and controls [18]- [21].…”

This journal discusses the implementation and testing of the electrical morphing wing system on light aircraft prototypes, namely technology on the wing to increase the value of aerodynamic efficiency on the wing surface with experimental methods based on knowledge obtained from various literature sources. Using a configuration of eight servo actuators arranged in parallel for the aileron and flap functions as well as setting and control with a six-channel Flysky-FSi6 remote to control the movement of the master and slave aileron actuators as well as the flap function on the morphing wing. The design includes the layout of the actuator, setting commands on the remote and wiring system electrical components. Other aspects such as rib design, mechanism and material selection affect the overall distribution of motion produced by the servo actuator. Through the design of the electrical system morphing wing design on the prototype aircraft, it is proven to be able to support the needs of the morphing wing motion mechanism with the concept of an arrangement of eight actuators in parallel on the rib morphing wing. It is hoped that the concept of the morphing wing can be implemented and further developed so that it can be used on full-scale aircraft.

O presente trabalho apresenta o estudo e comparação de dois algoritmos para a redução do ripple de torque de máquinas BLDC. Devido às suas características, como a forma de onda da força contra-eletromotriz, e dificuldade em sintetizar correntes retangulares, pode-se resultar na presença de ripple de torque quando a máquina BLDC é acionada. Para reduzir este ripple de torque, vários estudos são encontrados na literatura. Nesse sentido, o presente artigo apresenta a comparação de dois métodos para redução do ripple de torque de máquinas BLDC. Resultados de simulação são apresentados para demonstrar as vantagens de cada técnica.
