Roller bearings are essential components in machinery that facilitate smooth rotational motion between multiple parts. Though they are relatively inexpensive to purchase, the failure of even one of these bearings can add up to hefty costs in repairs if not used effectively. As such, it is essential to know the various factors that could cause bearing malfunction and maintain your assemblies accordingly. To learn more about these factors including how to best prevent them, read on as we discuss some key ways to safeguard your bearings from potential damage.

When operating aircraft with gas turbine engines, a starter unit is often required to help the engine attain the self-sufficient speeds necessary for standard operations. Start units come in a variety of types, and they are all considered Ground Support Equipment (GSE) as they are operated by airlines and ground handling agencies that utilize the unit during the final boarding procedures before departure. One of the most common types of unit is the air start unit (ASU), that of which may be found at most airports across the globe. In this blog, we will discuss the general design and functionality of the air start unit so that you can better understand its importance.

Stalling is a condition that no pilot wants to face, referring to an instance where an aircraft surface is not able to maintain smooth airflow, resulting in a decrease in lift. Stalls may occur through various means, and they are a hazard as they cause aircraft to sink in the atmosphere when there is not enough lift to overcome weight. While stalls are most often faced by the main wings of an aircraft, they can also occur around the tailplane. While tailplane stalls are not often discussed, they present a major threat to pilots and passengers. As such, having an understanding of how they come about, and how to recover from them, is highly important to maintaining safety across flight operations.

When working with fluid applications such as plumbing, it is paramount that ample flow management is in place to ensure that all materials move exactly how they need to through a system. One undesirable issue that may be faced in a system is backflow, that of which is when materials begin to move in the opposite direction as a result of pressure changes. While this takes away from steady performance, the backflow of substances may also lead to clogging, excess pressure, and other issues like contamination. As such, one should always take advantage of components that prevent backflow, such as a backflow preventer or check valve. While both of these devices operate on the same principle, their overall objective differs, making it important that one understands their differences and distinct applications.

While modern aircraft often have the tools and equipment required for instrument flight rules (IFR) for instances in which a visual reference is not safe, it can be highly beneficial to maintain sight out of the vehicle when possible. During conditions such as heavy rain, beadlets of water can gather up on surfaces, possibly obstructing the pilot’s view outside of the windshields. To remedy such issues, aircraft feature various forms of windshield wipers and systems.
