“…This improvement was reported in the researches [11][12][13]. In 2016, Lei et al, [14] studied the aircraft with horizontal tail surface which was added instead of using canard. The study results shown the reduction of the lift/drag ratio due to the downwash effect on the tail surface.…”

A forward swept wing was designed to use for a supersonic aircraft. Its aerodynamic characteristics were studied through experiments and numerical simulations which excluded the subsonic speed condition. For this paper aims to explore the aerodynamic characteristics of the forward swept wing in the range of subsonic speed by using a computational fluid dynamics method. In simulation, the airfoil shape of the wing model was NACA 3412. It was varied in both swept angle and angle of attack. The airspeed was given constant at 50 m/s. The simulation results indicate that the forward swept wing model is suitable for the aerobatic aircraft because lift coefficient and the stall angle of the forward swept wing model is higher than the non-swept wing model. Moreover, the aerodynamic stall of the forward swept wing occurs at the wing root which makes the aircraft able to maintain the controllability of the aileron surface at high angle of attack. However, the aircraft with forward swept wing model tends to consume more energy as compared with non-swept wing model. Because the maximum lift to drag ratio of the forward swept wing is less than the non-swept wing. Non-swept wing model has the maximum lift to drag ratio of 8.76 at the angle of attack 2°. While the forward swept wing 35° provides the maximum lift to drag ratio of 7.47 at the angle of attack 6°.

“…After the 1950s, due to the needs of aircraft design, the fluid mechanics theory in that period could not be used to solve the nonlinear flow problem. Therefore, many scholars used the time-dependent method to solve the steady flow around the aircraft based on the hyperbolic equation [8] . Computer simulation of steady and unsteady flow of fluids became a typical calculation method at that time.…”

Computational fluid dynamics has important application value and theoretical significance in engineering. Fluid mechanics has emerged as a way out of many engineering design problems. In recent years, applying fluid mechanics in the aircraft field has brought a breakthrough to problems that could not be solved previously. This paper mainly introduces the development history of the application of computational fluid dynamics in the direction of the wing and the specific application of this technology in the numerical simulation of the wing flow field. The aerodynamic characteristics of aircraft wings are related to the flight performance of the aircraft. The influence of wing aerodynamic characteristics, wing lift drag coefficient, and wing noise is a hot research issue. The influence of flow field research methods (such as numerical simulation) on the optimization and improvement process of the wing is analyzed, and the numerical results and simulation results of the flow field are found. The future development trend of the wing is proposed. Finally, it is believed that changes in airfoils will have a significant impact on aircraft performance.

“…As for a turbulence model, the Spalart-Allmaras model is used because it is relatively simple, which is used to figure out an eddy viscosity transport equation [ 14 , 15 ]. As the Spalart-Allmaras model is one kind of Reynolds-average Navier-Stokes (RANS) model [ 16 ], the Reynolds number and the turbulent magnitude are considered accordingly in this paper.…”

Aircraft service process is in a state of the composite load of pressure and temperature for a long period of time, which inevitably affects the inherent characteristics of some components in aircraft accordingly. The flow field of aircraft wing materials under different Mach numbers is simulated by Fluent in order to extract pressure and temperature on the wing in this paper. To determine the effect of coupling stress on the wing’s material and structural properties, the fluid-structure interaction (FSI) method is used in ANSYS-Workbench to calculate the stress that is caused by pressure and temperature. Simulation analysis results show that with the increase of Mach number, the pressure and temperature on the wing’s surface both increase exponentially and thermal stress that is caused by temperature will be the main factor in the coupled stress. When compared with three kinds of materials, titanium alloy, aluminum alloy, and Haynes alloy, carbon fiber composite material has better performance in service at high speed, and natural frequency under coupling pre-stressing will get smaller.
