Box wing plane

During the flight the wing of a model is influenced by aerodynamic forces that curve and twist it. In the construction of a built up wing curving forces are taken up by the spar and the twisting ones by the D-box construction. D-box is a tube in a letter D form in front of the spar. Now very few is left to be done.

In the construction of a built up wing curving forces are taken up by the spar and the twisting ones by the D-box construction. D-box is a tube in a letter D form in front of the spar. The back parts of the rib pass the load from the flaps and the wing skin to the D-box and the spar, that's why they must also be hard and strong enough.

Now very few is left to be done. It's just to make all the elements of the construction extra light and extra strong to achieve the needful for an ambitious flight stability.

Wingbox - Wikipedia

To achieve the most strength we prepare the plates of carbon with special epoxy for spars. Carbon fiber is a micro pipe.

That's why it is necessary to use special solvents for epoxy to saturate carbon fiber better. We use the so called prepeg gluing technology, which is widely used in the aircraft industry. Carbon is first imbued with epoxy which doesn't polymerize at the room temperature, then the needful quantity of layers and the plate are put into the form.

When this form is put into the stove there appears an excess pressure of about 30Bar and at the temperature C the epoxy polymerizes.

We create pressure to the carbon by screws and in addition silicon expands and create pressure of Bar. Thus received plates we glue to the balsa cut in vertical direction with epoxy in vacuum.

Then we cut this plate according to the needful sizes of the spare width and mould a place for the joiner in the matrix, wrapping it up with carbon rowing. In order to increase reliability the ready-made spar wound around with the kevlar thread.

In this way we achieve high strength and inflexibility by the minimal weight of the spar. The D-box coating, which is to take up the twisting forces, we make of Kevlar-carbon fiber which we place at angle of This covering is produced according to the same prepeg technology as a very thin film.

D-box and landing edges for Graphite and Simply the best we make using the same technology. This thin film, supported by the balsa rids, makes the wing extremely strong at the light weight. We cover the rids, cut out of balsa, with carbon strips to make them stronger The outer panels are connected to the inner panel with a removable CF wing joiner.

The wing is covered by the transparent Oracover.

The accuracy of fit is perfect here as it is throughout in the Graphite. An original construction was applied for the flaps and ailerons.

Spar of flaps and ailerons is a carbon pipe. We produce this pipe of carbon cord with the 45 grades direction thread. When we glue ribs with carbon cap-strips to this pipe, we get extra rigid and strong flap or aileron.

It's hard to believe but this flap or aileron is stronger and more rigid than a molded one.The larger wing area you have on an airplane, the more lift you have.

Your Answer

If an airplane has alot of lift and doesnt need that much thrust to power it, it is way better fuel efficient. That would more than likely be the reason for a box design. The wing box of an airplane is the structural component from which the wings extend.

It is usually limited to the section of the fuselage between the wing roots, although on some aircraft designs, such as the Boeing , it may be considered to extend further.

The box wing is only better when you compare wings with identical span. The two wings of a box wing work in different Treffz planes, so the downwash is spread out yunusemremert.com difference in induced drag to a single wing is not big, just a few percent. To the Flite Test Community; Susannah, 8th grade top design student at MESArc, came across a cool plane design that gave her the design itch to try to create the box wing style aircraft.

A closed wing is a wing that effectively has two main planes which merge at their ends so that there are no conventional wing tips. Closed wing designs include the annular wing (commonly known as the cylindrical or ring wing), the joined wing, the box wing and spiroid tip devices.
