Without electronic fuses, high electrical currents passing through a wire can lead to heat, melting, or burning. This melt can cause a break in the circuit and stop the flow of a circuit, leading to dangerous repercussions. To protect against this, fuses have become an essential piece of safety equipment in electrical wiring since the early years of electricity. Circuit breakers and fuse blocks also help in protecting against high currents that lead to wire troubles. Companies like Optifuse offer a great alternative to overpriced fuse parts and equipment by cross-referencing major fuse manufacturers like Littelfuse and Bussman, to offer industry standard fuses and fuse clip parts at a fraction of the cost.

The most popular types of fuses offered by Optifuse are automotive fuses and more specifically the blade fuse. As stated above, these fuses safeguard and ensure proper circuit wiring and electrical protection. Fuse blocks are another commonly used fuse product for automotive applications; these blocks are essential in protecting and consolidating blocks of fuses to keep automotive wiring systems safe and functioning properly. Industrial fuses are utilized on motors and branch circuits that deal with higher amps or volt ratings.

Wire regulations define a maximum fuse current rate for particular circuits in volts and these standards are maintained by industrial fuses. Well known in a residential setting is another form of common electrical protection, the circuit breaker. Circuit breakers protect against over-currents and help prevent electrical fires when a device has short circuited. These breakers automatically switch off electrical currents offering an important form of protection when over currents occur.

Pre-assembled fuse kits are available that are filled with the common types of fuses for most common application purposes. These are a great option to quickly order and fix burnt out fuses or freshly install multiple fuses at once. In conclusion, fuse holders and accessories like the fuse clip can help save space and ensure tight enclosure between the clip and actual fuse and should be considered as an extra layer of protection.

When connecting wires, one may think of the most rudimentary and basic method; a technique involving stripping the insulation and then twisting the wires together. While this does indeed work to create an electrical connection, it may not be the most optimal, and sometimes not very safe. This also does not allow for the connection of multiple wires, ability to create different configurations, or make for easy changes as needed. Luckily, all of these issues can be done much easier and efficiently through the use of a terminal block.

 A terminal block is a component that provides for an electrical connection of two or more wires. In their most simple configurations, they consist of some sort of frame, a component to secure the wires, and a conducting block or strip for the electrical connection of the wires. Terminal blocks enable motion and automation control systems to work, and can be seen in many commonplace appliances and electronics including ovens, dryers, and alarm systems. While basic terminal blocks serve use for electrical connections, they can also enable input/output, motor connections, power distribution, and other functions.

The distinction between various terminal blocks can often be denoted by how the connection between wires is established. Screw-in blocks are the most common, and feature a wire that is held against a conducting plate with the use of a screw. Spring loaded types are similar, through their clamping force is achieved through the force of the installed spring. There are also push in types where the wire can be placed inside the terminal block’s hole, as well as insulation-displacement types. Other notable differences that separate terminal blocks from each other include number of allowed connections, current ratings, voltage ratings, or the size of the terminal block as a whole.

The future of aerospace maintenance chemicals is an exciting one that, we, in the aviation industry can look forward to. Based on recent projections from the Market Research Future (MRFR), the market on global aerospace maintenance chemicals is expected to skyrocket at a significant pace over the forecast period.

So what is driving this sudden spike? Experts say the rise is being driven by stringent regulations being enforced by aviation authorities. Due to the various complications that can arise from airframes, engines, and other aircraft parts, the need for maintenance, repair, and overhaul (MRO) is a necessity. As more aircraft take into the skies, more will need to be maintained and repaired, which means good prospects for the use of aerospace maintenance chemical products. Additionally, development investments in the commercial aviation sector by chief market players such as Airbus and Boeing are likely to promote more market growth.

Regional Analysis:

Owing to the growing aerospace industry in North America, this region has experienced the largest market share for aerospace maintenance chemicals. Canada and the US are the biggest suppliers of such chemical products as a result of the augmented production of aircraft in the region. Meanwhile, Europe is also a significant market for aerospace maintenance chemicals and will retain a leading market share over the next few years because of the presence of crucial market players in the region, especially in the aerospace & defense industry. The consumption of the product has risen significantly in the UK, which has been a major contributor to the market share in the region over the review period.

The prize for fastest growing in the market would go to the Asia Pacific region, owing to the augmented demand for passenger aircraft in emerging economies such as China, India, and Thailand. In addition, the thriving tourism industry is expected to fuel the market growth in the region over the evaluation period. The Latin American market for aerospace maintenance chemicals is expected to witness considerable growth over the assessment period. This is attributed to the growing aerospace industry in emerging economies such as Brazil, which is one of the largest manufacturers of commercial aircraft in the region, resulting in market growth during the forecast period.

Keeping your aircraft clean is an important part of being a responsible aircraft owner. Whether you need a quick rinse or a detailed deep clean or accessory cleaning, there are countless products on the market. Finding the right product for you shouldn’t be a pain, but since some cleaning chemicals can have an adverse effect on your aircraft, it’s good to know which products to avoid. Here are five products that should never be used on your aircraft:

Ammonia-based Window Cleaners:

Keeping your aircrafts windows clean will ensure you have good visibility while flying, but your typical household window cleaners can cause serious damage to your fastener windshield. Non-aviation specific cleaners can lead to crazing, or tiny cracks on the windshield's surface. More than an annoyance, these cracks can obscure sightlines, refract light unpredictably, and lead to larger cracks causing irreparable damage.

Methyl Ethyl Ketone (MEK):

MEK has been a commonly used cleaning product in the aviation industry for some time. If used properly, it will not damage your aircraft, but discoveries in the last decade have found that it has an extremely negative effect on the user’s health. The Aerospace and Agricultural Implement Workers of America have stated that prolonged exposure to MEK can lead to chronic headache, asthma, flu-like symptoms, dizziness, malaise, and fatigue.

Chlorine Bleach:

While this is a good product for keeping domestic bathrooms clean, chlorine bleach should never be used in your aircraft lavatory. The chief concern is bleach’s ability to damage seals and the lavatory vacuum system by stripping away the protective layers of these components. Furthermore, if bleach is mixed with lavatory deodorant fluid (blue juice), it can fill the aircraft with toxic fumes.

Dish Soaps:

Cleaning the underside of your aircraft is crucial due to the buildup of grease, dirt, and oil over time caused by repeated takeoffs and landings. It’s important to use aircraft-specific cleaners for this because common dish soap are not suited for grease of this strength and will usually leave a soapy film/residue.

Wood Cleaning Products:

This is another chemical that can have a negative effect on your aircraft. These products are designed to leave a shiny film, but the film can actually leave a layer of wax that traps dirt and grease underneath.

Just as important as keeping your aircraft clean is using the proper cleaning materials. While these five are the most commonly used, there are many other cleaning products to avoid. The best way to ensure your aircraft’s safety is to use only aviation-specific products.

A first flight is a momentous occasion. It’s when years of planning, development, and manufacturing culminates in an aircraft’s first time in the sky, when all that hard work pays off and for most aircraft, they do so while painted in a drab shade of olive green. Why are prototype aircraft painted in such an unappealing shade?

The reason is because aircraft need to be primed before they are painted, and for aircraft primer of choice is a zinc chromate or zinc phosphate that adheres well to the aluminum that aircraft are typically made from. The greatest advantage of zinc chromate and phosphate primer, however, is that it has anti-corrosive properties — a serious concern for aircraft. Prototype aircraft on their first flight will get a layer of green primer to protect against corrosion, but will not get their actual paint-job until later. Additionally, if there are any surfaces of an aircraft that are colored blue, it is because those surfaces are made of lightweight composite materials, not aluminum, and therefore are treated differently to protect against corrosion.

Corrosion-resistant primer was first used by the Ford Motor Company in the 1920s, and adopted for use in commercial and military aviation in the 1930s. United States Army Air Corps documents mention using zinc chromate primer in 1933, and was made standard for use in 1936. Zinc chromate was also extensively used throughout World War 2 by the United States, while Germany and other Axis powers used lacquer-based protective coatings. The British would adopt zinc chromate primer in 1945 for the Martin-Baker MB5.

Despite their unappealing shade, first-flight aircraft are completely functional. They are, however, often almost completely empty as well. Commercial aircraft are first flown without seating or interior decor, for instance, while military aircraft’s first flights are performed without weapons systems mounted. First flights are effectively a proof of concept, showing that an airframe can function properly in the air outside of computer simulations and wind-tunnel testing. Only after subsequent test flights do engineers start installing interior components and slap a coat of paint on.
