“…MAVs are one of the largest groups that are vulnerable to gust loads due to their weakness in resisting gust loads (61,62,73,(158)(159)(160)(161)(162) . The flying speed of a MAV is around 10 to 20 m/s, which is at the same scale of the velocity of a normal gust.…”

An important prerequisite for the design, assessment and certification of aircraft and their associated control systems is a quantitative specification of the environment in which the aircraft is intended to operate, for example, atmospheric gust. Gust loads on aircraft may induce detrimental influences such as increased aerodynamic and structural loads, structural deformation and decreased flight dynamic performance. This paper presents a systematic and comprehensive overview of important concepts and applications of gust loads on aircraft. This overview includes a brief research background, concepts, research techniques, influences and load alleviation measures of gust. Finally, we summarise some potential improvements in the future work. It is also recommended to learn from previous experiences to avoid aviation accidents due to flight through atmospheric gusts and turbulence.

“…One of the visible characteristics of urban environment is with the high and dense buildings, which may block the air flow and result in back flow. 24,25 That irregular vortex will change the air velocity. When the vortex and the air have the same/opposite direction of flow, the wind velocity will increase/decrease.…”

Express by micro aerial vehicle (MAV) becomes more and more popular because it can avoid the influence of terrain and save more space for taking-off and landing of aircraft. At present, quadrotor is often used in the express industry due to its flexibility and easy operation, and the flight trajectory plays an important role in the efficiency and safety level of express service. In this paper, the trajectory planning problem is studied for quadrotor delivering goods in urban environment with the purpose of avoiding the heavy ground traffic, and a cuckoo search (CS)-based trajectory planning method is proposed to solve the problem. First, a conceptual model containing all the key elements of the delivery task is developed, which presents a general idea of solving the problem. Some characteristics of the urban environment and the delivery task, such as the wind field, dense buildings and inclination of shipped goods, are taken into account in the trajectory planning model. The goal of the delivery task is to make the goods reach the destination accurately. When designing the CS-based trajectory planning algorithm, the basics of CS algorithm are explained, and then it is integrated into the trajectory planning problem. Comparative experiments are carried out to investigate the superiority of the proposed method, and the influences of parameters in CS algorithm are also discussed to conclude its performance in trajectory planning problem.

“…The effects of synthetic-jet actuation are considered in application to unsteady flow over airfoils and analyzed using a high-accuracy compressible viscous ILES solver (Visbal & Gaitonde, 2002). FDL3DI (2015 version), is the updated solver used in our previous gust-airfoil and vortex-airfoil interaction studies (Golubev, Nguyen, & Visbal, 2010a;Golubev, & Visbal, 2012). In the numerical procedure, all variables are nondimensionalized by the airfoil chord and freestream flow density ∞ and flow velocity ∞ .…”
