![]() The first two types of blind rivets described are generally not as strong as solid shank rivets and therefore their use must be carefully planned based upon the strength of joint required. ![]() There are three types of blind rivet designs: hollow pull through rivets, self-plugging - friction lock rivets and mechanical locked stem self-plugging rivets. Blind rivets have similar design properties as solid shank rivets, however the formed head is made by drawing a stem or mandrel through the hollow shank of the blind rivet. Solid shank rivets are most common and consist of a manufactured head (mushroom head and countersunk), a solid shank and a driven head. There are three types of rivets: Solid Shank, Blind and Pin (Hi-Shear). If a joint is subject to a tensional force, a rivet is unacceptable and a bolt would be used instead. Generally rivets are used where shear strength properties are required. This article specifically addresses riveting as it relates to structural repair. Unless you are employed in the manufacturing environment where you are working under the direction of concise engineering drawings that specify the location, spacing and type of fastener that you are to use in each location and you are drilling the first installation holes in a new piece of structure, you are most likely to be proficient in riveting because of the need to perform structural repair. ![]() Now we are left with Monocoque and Semi Monocoque structures, which will require you to have a fairly detailed depth of knowledge of riveting tools, types and techniques (the subject of this article). As a mechanic you need to have a firm grounding in at least four of the five types of aircraft structures (forget about wire braced unless you want to build a Wright Flyer replica or similar).įor Truss Type Structure you will generally need to know how to weld steel tubing (a topic for another article), for Sandwich Structures you need to be familiar with exotic composite cloths, panels and epoxy resins (again a topic for another article). The aviation industry is again going through a transition, this time to sandwich structures. Wire Braced and Truss Type structures were popular right up to the middle of the Second World War, then Monocoque and Semi Monocoque structures became the norm. These are Wire Braced, Truss Type, Monocoque, Semi Monocoque and Sandwich. There are five types of aircraft primary structures that have been employed through aviation history. ![]()
