What is the benefits of box wing aircraft?
Box-wing aircraft designs have the potential to achieve significant reductions in fuel consumption. Closed non-planar wing designs have been shown to reduce induced drag and the statically indeterminate wing structure can lead to reduced wing weight.
Which parameters of the wing geometry affect its aerodynamics?
From the literature [1, 6, 7] it is known that the h/b ratio is an important parameter for the BWA aerodynamic characteristics. Hence this parameter is chosen to be variated together with the aspect ratio and taper ratio. Once that the wing area is constant, the aspect ratio is resulted from chosen span values.
What planes use wing boxes?
The wingbox on all amphibious aircraft, including the Canadair CL-215, is located at the top of the fuselage so as to both provide clearance for the wings and avoided repeated stress when landing in water. Aircraft in flight experience concentrated shear stresses on their wings.
Where is the wing root?
The wing root is the part of the wing on a fixed-wing aircraft or winged-spaceship that is closest to the fuselage, and is the junction of the wing with the fuselage. The term is also used for the junction of the wing with the opposite wing, ie on the fuselage centerline, as with the upper wing of a biplane.
Why are wings swept back?
The main reason airplanes have swept wings is to reduce turbulence. During flight, airplanes encounter turbulence from the friction created as air runs across the plane’s wings. The speed at which an airplane flies will affect the amount of turbulence is encounters.
Can box wing design improve the aerodynamic performance of slow flying aircraft?
The box wing design has tremendous potential for improving aerodynamic characteristics of slow flying aircraft. The mission chosen for this project is to vary a few design parameters to improve the aerodynamic performance of a box wing aircraft as applied to Unmanned Aircraft Systems (UAS).
What is the weight of a box wing aircraft?
The box wing aircraft in this experiment is designed to act as a medium to large capacity, long-range aircraft. The maximum takeoff weight (MTOW) of the design is 250,000 kg (551,156 lbs.) and the maximum range with payload is 13,500 km (8388 mi). Current comparable cantilever aircraft are listed in Table 1. 4
What is a box-wing design?
For the purpose of this research study, the student designs a Computer Aided Design (CAD) model of a multi-planar wing aircraft, also known as the box-wing design. The box wing design increases the aspect ratio of a conventional aircraft as shown in Figures 1 and 2 [2].
What is a box/joined wing aircraft?
Box/joined wing aircraft potential of improved fuel efficiency and reduced direct operating costs have been other reasons to investigate the configuration. Box/joined wing aircraft have different names, such as box wing, biplane and diamond wing. The essential difference is in the wing con- figuration and the principle of operation; see Figs 1 and 2.
