The fus is the main structure of an acft which houses the crew, and sometimes the armament and the power plant. The tail surfaces or empennage and landing gear are attached to it. The fus also contains the pilot cockpit with a canopy.

Regardless of the attitude of an acft, there are always stresses on the fus structure. It must be constructed to withstand all such stresses. Detail design depends upon the function and structural requirements to the acft.

 

Wings

The wings are designed to develop the major portion of the lift of a HTA acft. Wing const is similar in most modern acft. The wing is a framework composed chiefly of spars and ribs covered with metal.

Рис. 3. Wing construction:

1 - spar -лонжерон; 2 - rib -нервюра; 3 - stringer -стрингер

 

The spars are the main structural members of the wing, extending from the fus to the tip. All the load that is carried by the wing is ultimately taken up by the spars. Ribs give the wing section its shape and also transmit the airload from the wing covering to the spars. They extend from the leading edge to the trailing edge of the wing.

A complete wing assembly consists of the surface providing lift for the spt of the acft, together with the nec flight control surfaces.
