torsion box

The result was a torsion box, which made the ski much stronger.

In 1975 the torsion box ski construction design is patented.

A hollow core door is probably the most common example of a torsion box (stressed skin) structure.

However, it was during this period that the fibreglass torsion box design started to become popular, and improved rapidly.

Forward of the single spar the wing was covered with a stressed metal skin, forming a torsion box.

The wing ahead of this spar, positioned at 30% chord, forms a plywood covered torsion box.

The fuselage is built around a wooden torsion box that is foam-filled for stiffness.

The wings are built up around single spars, with ply covering to the leading edge forming a D- or torsion box.

The D-type leading edge torsion box is of plywood and the whole wing is fabric-covered.

The wings were skinned with plywood forward of the main spar to form torsion boxes which increased their rigidity.

They were built around a single spar with a plywood covered leading edge torsion box in front of it and fabric covered behind.

Forward of the spar the wings were ply skinned, forming a D-shaped torsion box.

The leading edge was a plywood torsion box, supported by Styrofoam, and the rest of the wing was fabric covered.

The wing had a single spruce spar with stressed ply to the leading edge forming a torsion box.

The wing consists of two cantilever sections attached to a central torsion box, forming a single unit with the fuselage.

The only major change in ski design since the Standard is the use of a fibreglass torsion box in place of the aluminum layers.

The wings and tail surfaces were covered with fabric, but the leading edges of the wing formed a stressed skin torsion box structural member.

A contemporary ski's torsion box design greatly improved torsional stiffness and would allow even greater sidecut to be effective.

It was Gaboon plywood-skinned and built around a single spruce spar, with a leading-edge torsion box.

Ribs, ailerons and Schempp-Hirth airbrakes are attached to this torsion box.

The composite wing used a flexible S-glass torsion box spar, with stiff kevlar skins.

The wing of the Wanderlust was built around a single spar, which with plywood skin around the leading edge formed a torsion box.

Torsion box designs continue to dominate cross-country ski designs, but is less common for alpine and ski touring.

It is built around a single spar with a D-shaped torsion box formed by the corrugated leading section, the ridges running chordwise.

The wing had constant chord, rounded tips and dihedral (aircraft) of 2.5 throughout, built around a two spar torsion box.
