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.
 
Since the aircraft battery serves such an important role, it’s vital that it receives regular maintenance check ups. For a basic outline on aircraft battery maintenance, see below. We will be using the Ni-Cad battery as an example.
 
Periodical Checkups
 
When it comes to the Ni-Cad battery, they should receive check ups based on the flight time of the aircraft start generator/(discharge) recharge cycle and age of the battery. The maintenance checkup is based upon the aircraft’s flight profile as well as the manufacturer’s recommendations. These check ups will typically consist of a virtual inspection of the overall internal and external condition of the battery as well as a voltage check. When doing this, you should be on the lookout for excessive voltage differences (0.25 volts or more) between cells.
 
Disposal
 
Ni-Cad batteries, when stored, should be in a discharged state. This means that it should be at zero detectable volts. In the aviation industry, this is referred to as “strapped off.” Once the battery is strapped off, it can be safely stored in a dry cool environment for long periods of time. And as usual, always follow any additional instructions provided by the manufacturer.

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.
 
So is there anything particularly special about bulkhead seats? Some people might think so. Bulkhead seats offer significant differences to the flight experiences that other seats, particularly those in economy, tend not to offer. The main difference is that there are no seats in front of bulkhead seating, meaning you’re at a lengthy distance from other people. Some people, especially taller individuals, might enjoy this feature because they have room to stretch out their legs. Other people who do not do well with crowded spaces might also enjoy these seats because there is no person in the front leaning their chair all the way back. Depending on the airline, you may be able to place your carry on bags right in front of you.
 
There are some cons to bulkhead seating, however. The standard airplane seat will have a leg rest underneath. If you are seated in basic Economy, you can prop your legs up on the leg rest right in front of you. If you are seated in a bulkhead seat, there is no leg rest for you to use, which can be especially tiresome during longer flights. For any inquiries on aircraft part details, consult the folks at ASAP Fasteners.

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.
 
Causes of Loose Bolts
 
Shock: Long hours with alternating heavy loads can create a lot of strain on machinery, no matter how fortified or robust it may have been built. While the bolts may be able to withstand impact and heavy loads, the more frequent it has to endure it, the worse the wear. A sudden force applied to the bolt or the joint can cause the bolt to slip relative to the threads of the joint, the slippage of which can ultimately lead to bolts loosening.
 
Under-tightening: As is evident on any kind of assembled machinery, a loose bolt that is not properly tightened cannot be guaranteed to hold upright any adjoining segments together. By definition, the joint does not have enough clamp force to hold the individual sections together. This could potentially lead to sideways slippage between adjoining parts, which places an unbearable stress on the bolt that could eventually cause the entire assembly to break.
 
How To Prevent
 
Washers: There are many types of washers that have been designed with ribs, fluting, or teeth that cling to the surface of the joint while it is being tightened. The only con for this method is that it can result in permanent damage to the joint finish or surface, which may ultimately deem it as unacceptable according to FAA and other aviation regulations.
 
Mechanical devices: There are a number of ways that you can prevent a too-loose bolt and one of them is simply by using mechanical devices to lock a tightened nut into place on a bolted joint. Castellated nuts, for example, have a slotted end and are used with a cotter pin or wire that fits through a hole drilled in the bolt. On the other hand, tab washers have two tabs on opposite sides, which fold up to secure the bolt head or nut after installation, and may have teeth that can penetrate the surface of the joint to hold it in place.
 
Ultimately, there are several methods that you can implement to ensure your bolts are properly installed and maintained. For more information on bolts or other fasteners, reach out to the expert team at ASAP Fasteners.

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.
 
Certain aviation seals with the highest demands require special engineering to meet the required performance levels. Because of this, significant research and development goes into the production of seals from composite materials. The introduction of composite seals has redefined what a seals’ function can be. They can be produced from a wide array of materials such as silicone, stainless steel, aluminum, or plastic depending on specific needs. Composite compounds have been especially useful for application on the exterior of aircraft in parts like flaps, rudders, and door seals, all of which have high demands and need seals designed specifically for that purpose. For example, wing seals need to be impervious to corrosion, so special materials are added to the composite to protect the seal.
 
Another way to specialize aircraft seals for certain tasks is to reinforce them with other materials. For instance, some seals need to be resistant to a massive range of temperatures from -40 F to 1,000 F. For this type of seal, a mix of silicone, fabric, and metal, reinforced with aluminum is used. Other seals have to be resistant to smoke, which can be done by reinforcement with materials specifically designed to be flame resistant.
 
With varying but equally-important requirements, aircraft connector seals are not a one-size-fits-all part. A seal tailored to your specific needs will last longer and operate without a hitch. At ASAP Fasteners, owned and operated by ASAP Semiconductor, we can help you find the seals you need and many other unique parts for the aerospace, civil aviation, and defense industries.

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.

Dzus turnlock fasteners have a stud, grommet, and receptacle. The stud is made from steel and are cadmium plated. There are three head styles: wing, flush, and oval. Turning the stud clockwise locks the fastener and turning it counterclockwise unlocks it. This is done using a specialized tool. The force that locks the stud in place is created by the spring.

Some of the most commonly used Camloc fasteners are the 2600, 2700, 40S51, 4002, and the stressed panel fasteners. Camloc fasteners are used on aircraft cowlings and fairings. The fastener has a stud assembly, a grommet, and a receptacle. Receptacles are sorted into two categories: rigid type and floating type. The receptacle is fastened to the aircrafts structure and the stud and grommet are installed in the removable portion while the stud and grommet are installed in a plain, dimpled, countersunk, or counterbored hole.

Anchor Panel fasteners have a stud, a cross pin, and a stud receptacle. There are flush, oval, and wing studs. It is important to know the thickness of the material being secured, as it has to be determined in order to choose a stud of the correct length. The cross pin is made from chrome-vanadium steel that has been heat treated. They provide the greatest strength, wear, and holding power. Once a cross pin is removed from the stud, a new one must replace it.

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.

They come in various styles, sizes, and material which should be able to fit all your fastening needs. Once a rivet is installed with a hammer or other such tool for installation, the “tail” is flattened, creating a permanent fastening solution. We will discuss the different types of rivets and their best features.
  1. The blind rivet is reliable for heavy load usage. They are often used for blind holes and when they have limited access.
  2. Drive rivets offer a low-profile solution. It is a common type of blind rivet.
  3. Solid rivets are the original rivets. They are resistant to water, vibration, and other kinds of tampering, as well as most severe conditions like wind and rain.
  4. The split rivet is typically used for sensitive situations such as thin wood, veneers, plastic, and leather.
  5. Tubular and semi-tubular rivets are used for quick and easy installations.
  6. Threaded inserts and rivet nuts are strong and permanent options for integrating seamless fastening.
Rivets are versatile and used in a wide variety of industries. One of the biggest applications for rivets is in construction, whether for windows or wall installations, rivets are used everywhere.

Another common application is in transportation infrastructures, such as for building bridges and overpasses. Rivets are also used in woodworking, jewelry, aerospace, and aviation for all types of projects ranging from necklace clasps to aluminum alloy construction and aircraft assembly.

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.

The HI-LOK Pin is widely used in the aviation industry for installation on airframes. This type of fastener is small in weight and size, easy to install, and has a controlled preload, making it the perfect choice for today’s high-performance aircraft. The HI-LOCK Pin Fasteners has been labeled the most reliable fastener by many in the aviation industry, making it every company’s first choice.

The pin is a threaded fastener that combines features of a bolt and a rivet and contains two parts: a collar and a pin. The fastener is so small it can be easily installed by a single person using power tools or even hand tools. This allows for less worker fatigue allowing for fasteners to be installed in a shorter amount of time. The weight of the HI-LOK pin is less than that of a traditional nut and bolt system, allowing for the overall airframe structure to be lighter.

These fasteners are also made to withstand high stress and high-temperature situations, making them the ideal match for aircraft adaptation over time. The HI-LOK pin fastener is available in several different head types to accommodate tension, mixed, or sheer application requirements. The pinheads are also designed to be self-aligning, allowing for optimized performance even on sloped or uneven surfaces.  The HI-LOK pin is the best choice for all airframe requirements.

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.

Having been through nearly 20 years of development already, the F-35 Joint Strike Fighter has seen and experienced several changes. Over the past 20 years, we have been able to establish a significantly better understanding of stealth as well as counter-stealth technologies, subsequently affecting the design of the F-35 Joint Strike Fighter.

Northrop Grumman’s most recent design features a tailless fighter. The cockpit and nose of the sixth generation fighter jet will be similar to the F-35 Joint Strike Fighter, while the wings of the aircraft will be similar to those of the X-47B unmanned aerial vehicle. The fighter jet will be very large in order to carry large amounts of fuel, as the F-35 has received criticism for its relatively short range which could potentially put American aircraft carriers within range of conflicting DF-26 as well as DF-21 carrier-killing ballistic missiles.

Northrop Grumman’s latest design, similar to the F-22, will almost certainly be capable of cruising above the speed of sound, though it is unlikely to be a dogfighter. The aircraft’s size will better enable it to utilize long-range radars and missiles in order to destroy opponent aircrafts, before they can even come into range for dogfighting to occur. The fighter aircraft will most likely utilize its stealth, advanced networked sensors, as well as speed in order to detect an enemy aircraft, gain a positional advantage over this aircraft, and then ultimately attack the said aircraft.
