Aircraft are regularly subjected to a variety of stressors throughout operations, making it important that they are well maintained while having protection wherever possible. Whether an aircraft is in flight, being cleaned, or simply sitting in a hangar, all metal surfaces will face a risk of corrosion, the risk simply varying based on a number of factors. Corrosion can lead to various issues like pitting, and if left unchecked, the aircraft can be rendered unfit for use in just a matter of years. While regular washing and other practices that can uphold quality, one of the best ways you can deter corrosion early is through the use of pretreatments, primers, and paints.

Aircraft are complex vehicles, often consisting of millions of parts that come together to make flight operations possible. Depending on the structure of an aircraft and the materials making up its assembly, varying methods or processes may be carried out to join parts together. While fasteners and welded joints account for a significant portion of connected parts, adhesives are also commonly used for structural applications for the means of bonding parts, filling gaps, sealing openings, and more. In this blog, we will discuss the most common types of structural adhesives that are used in aerospace applications and the various benefits that they present.

Adhesives are used in nearly all industrial sectors, all of which are made with varying strengths to meet a myriad of operational requirements. Aerospace adhesives in particular are generally considered more volatile than conventional variations. Typically, they cover the interior, exterior, and engine compartments of various aircraft, and their applications range from thread locking and retaining to gasketing, thread sealing, and more.

The world of aviation has countless terms and acronyms that pilots are expected to memorize. IFR and VFR are just two prominent examples that are critical for student pilots to become familiar with. IFR stands for “instrument flight rules,” whereas VFR is “visual flight rules.” With similar shorthand spellings, people often confuse the two. To better understand their importance, this blog will cover their unique features.

Compression spring components are useful for a wide variety of systems and applications, serving to store mechanical energy when compressed. This means that as such springs are compressed through the application of a load, they will become shorter. This causes a significant potential force as the compression spring will attempt to return to its standard shape and state upon the load being removed. As compression springs can be reused many times, they are quite useful for actuators, moving systems, and other such applications. Based on the particular needs of an application, there are many types of compression springs one may choose, and it is important to make the right choice when choosing between options as not all compression springs function the same. In this blog, we will discuss conical springs in particular, those of which feature a unique shape that offers specific properties not found in other standard options.
