When you’re giving someone directions, odds are you’re doing so in relation to a separate location both you and the other person know. For instance, you might say something like “Go to the coffee shop on 5th Street and turn left.” This is because having an accepted position or reference point is extremely helpful in providing clear directions. This same concept is applied to astronomy, surveying, navigation, or any other related action.

Needle roller bearings are specialized roller bearings that employ long, thin, needle-like cylindrical rollers. While standard roller bearing rollers are just minimally longer than their diameter, needle bearings have rollers that can be four times longer than their diameter or even more. Similar to a standard bearing, the purpose of needle roller bearings is to reduce the friction of a rotating surface. A significant advantage of needle roller bearings is their large surface area in contact with the tracks/races, allowing them to support a heavier load. Despite their large surface area, they are also thinner, meaning they require less clearance between the axle and surrounding component. This blog will provide some insight into needle roller bearings and their function in the aerospace and aviation industries.

A fastener is a component that is often used in several different appliances including furniture, automobiles, and of course, airplanes. Manufacturers and others working in the supply chain industry find fasteners very useful because of the way they can attach and hold two or more objects together. Captive fasteners, however, operate a little differently. The captive fastener is embedded in one part of the object and then the other part of the object is then anchored inside the fastener.

The aircraft battery is an essential component of aircraft as it acts as a primary source of power for most of the aircraft’s electrical needs, including cabin lighting, heating, air conditioning, etc. More significantly however, the aircraft needs a stable functioning battery because it will act as one of the last lines of defense in the case of an emergency.

Unless they work directly in the aviation industry, most people aren’t aware of bulkhead seating on an airplane. That’s no surprise because on most flight booking sites that allow the option of choosing seats, there is no mention of bulkhead seats (though you can certainly see the option on the seat map). The bulkhead in an aircraft refers to the dividing walls between cabins (on smaller aircraft, this will usually be a curtain). The seats in front of this wall are the bulkhead seats.

A loose bolt on heavy duty equipment may not seem like a big issue at first thought, but the reality is that the tiniest bolt can cause the biggest issues, if not properly installed. A loose bolt on a helicopter, for instance, can potentially cause a whole series of issues down the road. That’s why it’s important to keep an eye on the bolts in your aircraft and be proactive in implementing measures to prevent them from becoming loose. Below you’ll see a few different reasons why a bolt may become loose and some things that you can do to prevent that.

When you’re cruising at 35,000 feet, it’s important to know that you can rely on the many seals throughout the aircraft you’re on. Whether they’re on the exterior flaps or the cockpit fastener windshield, a failed seal can have a huge impact on an aircraft’s performance. Aircraft Seals have to be up to snuff to deal with harsh conditions like extreme weather, high air pressure and dramatic swings in temperature. Some seals are even exposed directly to fuel and chemicals during manufacturing or operation.

Aircraft inspection plates, doors, and other removable panels are secured with turnlock fasteners because they allow quick and easy removal of panels for inspection and servicing. These fasteners require positive sustained torque to unfasten and tend to correct themselves after minor disturbances. The most common manufactured turnlock fasteners are Dzus, Camloc, and Airloc. Some of the common names used to refer to turnlock fasteners are quick opening, quick action, and stressed panel fasteners.

Rivets are simple to install and a versatile alternative to nuts and bolts. For those of you who have never encountered a rivet, it is a cylindrical piece of hardware with a “head” and “tail” on either end.

In the aerospace industry, fasteners are essential— they are the glue that holds every unique airframe piece together. Fasteners are defined as hardware that mechanically joins or affixes two or more objects together. This hardware can be applied to many applications across several industries. LISI Aerospace, a global manufacturer specializing in fasteners and structural components, makes a specialized fastener called an HI-LOK Pin Fasteners.

Northrop Grumman Corporation, the American global defense and aerospace technology company, has recently revealed a concept drawing for their new sixth-generation fighter design. This sixth generation aircraft will be unlike any other fighter before it. Despite the fact that the fifth-generation F-35 has recently just started production, designers are already eager to get a head start on designing the airplane which will replace the F-15E Strike Eagle, F/A-18EF Super Hornet, and F-22 Raptor.
