Composite materials are a commonly-used resource in the aviation industry, and for good reason; their unique properties let engineers overcome design obstacles that would be otherwise impossible to solve. Common composite materials include fiberglass, carbon fiber, and fiber-reinforced matrix systems. Fiberglass is the most common, and was first widely used in boats and automobiles in the 1950’s, the same decade Boeing introduced the material in its passenger jets. Today, aircraft structures are often made up of 50 to 70 percent composite materials. While composite materials have many advantages, there are also some downsides that some fear pose safety risks in the field of aviation. In this blog, we will break down the greatest pros and cons for composite materials in aviation.
The greatest advantage of composite materials is how little they weigh compared to metals such as steel, titanium, and even aluminum. Composite materials can drastically cut down on the weight of an aircraft, which leads to better performance and improved fuel efficiency. Fiber-reinforced matrix systems are often stronger than traditional aluminum in most aircraft, and provide a smoother, more aerodynamic surface, which also improves performance and fuel efficiency. Composite materials do not corrode as easily as other structure types, and they do not crack from metal fatigue the way aluminum does. Instead, they flex, which lets them last longer than metal, which in turn means lower maintenance and repair costs.
However, the greatest disadvantage of composite materials is that they do not break easily. This may seem oxymoronic, but this means that it is difficult to tell that the interior structure of the aircraft has been damaged. Because aluminum bends and dents more easily, it is easier to detect a need for repairs. Composite materials are also more difficult and more expensive to repair than metals, although it can be argued that the long-term savings of using a more resilient material off-set this cost.
Another issue is that composite materials use a type of resin, which weakens at temperatures around 150 degrees Fahrenheit. This makes it necessary to take extra precautions against fires. Burning composite materials can release toxic fumes and micro-particles into the air, both of which are serious health risks. At temperatures above 300 degrees, structural failure can occur.
Internal combustions like those found on propeller-driven aircraft need a consistent and reliable source of ignition for their engines. Aircraft Magnetos are the most popular choice for fulfilling this need, and consists of a self-contained electrical generator that uses magnets to produce a high voltage current that fires the engine’s spark plugs, which in turn provide the ignition needed for the engine to function. Magnetos boast a simple design, which makes them compact and reliable, and they require no external electrical source. This is a critical component of their design, as they allow the ignition system to keep running independently of the electrical system, which protects them from an alternator or battery malfunction.
A magneto consists of a rotating magnet in close proximity to a high-output coil. As the magnet spins, it generates electricity until it reaches a spike of 20,000 to 30,000 volts. When this voltage spike is achieved, a distributor carries the amplified current to the spark plug, which ignites the fuel air mixture to fire the pistons.
Aircraft piston engines are designed with two independent ignition systems, with two spark plugs per cylinder. To go with this, there are two magnetos, left and right. The left aircraft magneto fires one plug per cylinder, while the right aircraft magneto fires the other. This redundant system ensures that the ignition will keep sparking even if one magneto fails.
There are several different types of magnetos: slick, single and duo.
Slick magnetos are lighter and smaller than other magnetos, which makes them easier to install. They are also quieter, which removes the need for magneto filters. Slick magnetos rae often engineered for balanced wear, which means that servicing and replacing them is more predictable.
Single magnetos, or Bendix magnetos, are known for their light weight, compact design, and reliable nature. They can be either impulse coupled or direct drive, and have a feed-through capacitor that filters out radio noise from the magneto. Bendix magnetos can reach higher voltages, which allows for higher altitudes of flight.
Dual magnetos are an arrangement where the left aircraft magneto and right aircraft magneto are contained within a single housing, and operated by a single magnet rotor and engine drive. Housing both of the magnetos together reduces weight and space, and allows for more regular maintenance of the ignition system.
Maintaining an aircraft is far more than washing the exterior and cleaning up the interior of the cabin. The maintenance cycle can be defined by various levels, each named with an alphabetical letter in progressing levels of complexity. Check A is the most routine, taking no more than an hour or two. Check C on the other hand, is a far more extensive checking of independent aircraft components, functions, tooling, and equipment.
Before flight, the pilot or mechanic is required to visually check the aircraft components and instruments. Access panels should be inspected for any obvious signs of damage. Oxygen systems and emergency lighting must also be checked to ensure they are functioning properly. Inside the cockpit, the pilot should verify that the brake accumulator pressure is correct. To help understand the various check stages, this blog will track one particular aircraft component throughout the check stages. The reciprocating engine is the main component of a jet therefore requires adherence to correct safety regulations. During Check A, the pilot cannot fully inspect the aircraft engine, but can check for any instrument irregularities.
Both Check A and Check B are known as lighter checks and can be performed at Fixed Base Operators such as the airport. Check B may require special equipment or tests to determine the status of a system of component. Disassembly is not necessary during this check. Engine diagnostic equipment is an example of a specialized kit that may be used during check B.
Heavier checks are contracted out to Maintenance Repair and Overhauls facilities (MRO)s. The aircraft is disassembled and categorized into parts. Each component is checked for any physical irregularities such as cracks, corrosive damage, heat damage, or dents. If a part has any of these, it is replaced. Specialized equipment and checks are needed to successfully carry out this stage of testing. Hardware such as seals, aircraft stabilizers, and bolts also need to be tested and verified.
The FAA has the final say in terms of the safety of the aircraft. Title 14, Section 19, of the FAA Code of Federal Regulations states that no person can operate an aircraft unless it had both an annual inspection and an inspection for the issuance of an airworthiness certificate. Each person carrying out the 100-hour inspection is required to fill out a checklist that includes the scope of work and details of the item they are checking. Further regulations for aircraft maintenance, specifically turbine-engine-powered aircraft, are set forth in Part 43 of the CFR. After the 100-hour inspection is complete, but before the aircraft is returned to service, the turbine engine must be run to determine satisfactory performance in accordance with the manufacturer’s recommendations.
Finally, everything and anything to do with the maintenance of the aircraft must be documented. If a part is classified as ‘life limited’ by design, the part must be replaced within a specific timeframe. The life status of a part is the accumulated cycles, hours, or replacement limit of a part. With both of these classifications, a mechanic can identify which parts will need a replacement, regardless of their physical condition. The maintenance of a jet engine is highly regulated process that cross references the physical condition of the aircraft on a daily, monthly, and yearly basis with the written documentation of the previous conditions and of the aircraft. The FAA will only deem the aircraft airworthy when every one of the regulations are met.
When buying electronic parts, there are many factors to consider. It’s important to be able to find the aviation components you need without unnecessarily overpaying, and to be sure you are purchasing the right product.
The first step is to search the market for pricing, availability, and lead times if the product is out of stock. The most efficient way to do this is to use aggregator websites. Here, potential customers can see distributors’ listings and compare prices and availability all on the same site. It’s much more efficient to use these types of sites rather than Google, because you can find many electronic parts distributors who stock the part without going back and forth between the multiple sites Google generates. Not to mention, Google search results are not always reflective of popularity or relevance thanks to features such as Google Ads.
It’s better to reach out to smaller distributors rather than large-scale distributors. Larger organizations sound appealing because they will almost always have stock for the part and be able to deliver quickly. However, this usually means they can charge higher premiums for their services. Smaller authorized distributors will also carry stock and provide same-day shipping. Also, they tend to have lower prices. Speaking to a sales representative over the phone and forming a connection may even help bring the cost of parts down.
You will want to make sure, when you’re ready to purchase, that you are buying from an authorized distributor, regardless of whether they are large- or small-scale. The additional step of requesting certification for the part in question is a good idea for product verification and quality assurance. Although non-authorized distributors may have stock when authorized distributors do not, they may not be able to provide certifications without an added cost. Ultimately, the safest bet is to buy straight from the manufacturer or from their list of authorized distributors.

The most important part of an aircraft engine, arguably, is the lubrication system. But it’s also the most vulnerable. Generally, lubrication systems are recirculatory. Fresh oil is introduced to the lubrication system and met with bearings, seals, and gears that wear and erode, producing abrasive contaminants. The oil flushes them away and carries them to the scavenge oil flow away from the sump where they are almost completely filtered out.
Thus, the oil can go through and be resupplied into the system. Unfortunately, because the oil has to pass through small holes and passages, even the smallest particles can block the oil flow and cause lubrication failure if it’s not properly filtered.
Normally, fresh oil will gradually dissolve contaminants and hold microscopic particles in suspension such that there is a normal level of contamination reflective of the condition of the system. Larger than normal particles can be collected by the filter, but because the filter inspection intervals are too long, these particles can have ample time to cause further damage. As a result, magnetic chip detectors are often installed in the scavenge oil flow of each sump or in the common scavenge line downstream of the pumps. Because the gears and bearings are made of steel, the magnetic chip detector can easily collect particles from 0.02 to 1 mm in size. The chip detector has to be regularly checked and maintained, and the particles can be sent to a lab for analysis.
Another tool for monitoring lubrication systems is the Spectrometric Oil Analysis Program (SOAP). As a maintenance tool that uses an emission spectrometer to check the condition of oil lubricated mechanical systems, SOAP can analyze the specific elements and concentration of particles from 0.001 to 0.02 mm in size. There’s always a certain level of normal contaminants, but periodic analysis with SOAP will show any increases in particle concentration or size, which will indicate if there is increase in wear or damage. When used with a magnetic chip detector, SOAP is a very useful tool in engine maintenance and repair.

In an interview with Hush-Kit, the alternative aviation magazine, Bing Chandler, a former Lynx Observer from the Joint Helicopter Command and the British Army Air Corps Center, talks about his top 10 attack helicopters.
10. Eurocopter/Airbus Helicopters Tiger, a Franco-Germain effort, earns the number 10 spot because of a very cool scene in the James Bond film, Goldeneye.
9. HAL Light Combat Helicopter, an Indian copter developed with the help of the former MBB, has unknown potential despite its typical formulaic design.
8. Denel Rooivalk, a massive South African copter with an empty weight of 5739 kg, is able to operate for prolonged periods without sophisticated support (because of the arms embargo enacted on South Africa by the UN for its apartheid policies).
7. Agusta/Augusta Westland/Leonardo Helicopters Mangusta, an Italian copter, also has a formulaic design, but has been continuously upgraded and improved.
6. CAIC Z-10, a multi-national effort also with a formulaic design, has proven itself a pretty effective light attack helicopter.
5. Kamov Ka-50/52, a Russian copter, despite its limited maneuverability, is noted for its unique design and for being the world’s first copter with a rescue ejection system.
4. Mil Mi-24/25/35, a Russian copter, the Mil Mi-24/25/35 has seen a lot of conflict since the Ethiopian insurgencies in 1978 and had many chances to prove itself with its speed, tough armor, weaponry, and ability to deploy up to 8 troops.
3. Mil Mi-28N, a successor to the Mil Mi-24 that didn’t garner much interest from the Russian government, has had continuous development that not only improved the navigation equipment, but allows for night and all-weather operation.
2. Bell AH-1Z Viper, based on the SuperCobra, is a copter that has taken a legacy of excellence and managed to make it better, reducing vibration levels, adding weapons, etc.
1. Hughes/McDonnell Douglas/Boeing AH-64D/E Apache/Guardian, the most famous and most prolific of attack copters, has been the standard to beat since its first flight about 50 years ago as a result of continuous development and upgrades.

UTC Aerospace Systems (UTAS), operating under United Technologies, is one of the world’s largest suppliers of aerospace and defense products. UTC develops, manufactures and delivers parts to some of the biggest names in the aerospace industry. As a premier Boeing parts supplier and Airbus parts supplier, UTC has been hit hard with increases in production rates demanded by these OEMs.
UTC’s CEO, Greg Hayes, said during the company’s first-quarter 2018 earnings call,
“At Pratt & Whitney we are at rate 55 with geared turbofan engines...and we have committed to take the rate up over the next couple of years. But for the second- and third-tier suppliers, I question if the sub-tiers really have enough capacity. If we are going to see big jumps in A320neo and 737 production rates, it will be a problem, so you will see big bottlenecks.”
One of UTC’s major issues with this increase is not just a shortage of available materials, but the company’s deficiency of skilled production personnel who are capable of handling orders of this magnitude. OEMs including Airbus and Boeing, and other UTC-related companies, are showing backlogs as long as seven years for narrowbodies, which will be a near-impossible feat to complete without a strong production team.
UTAS’s electronic systems are generating lower margins for new-generation aircraft than they do for older generation aircraft. The newer systems use fewer moving parts, making them more reliable overall, but less than expeditious. Recently, UTAS’s CEO stated the company is “very focused on lean manufacturing techniques to continue to take margins out as older aircraft are replaced by newer, lower-margin” ones.

In the aerospace industry, unmanned aircrafts have created a name for themselves in recent years as they no longer put an operator into risk as standard aircrafts. Creating new heights for uncharted territory, the career of the unmanned aircraft is well on its way to a soaring future.
Boeing one of the industry’s most astounded manufacturer has released a new unmanned aircraft prototype that introduces a newer way to aircraft. The aircraft is known as the unmanned electric vertical- takeoff and landing (eVTOL) cargo air vehicle (CAV) prototype. Boeing has begun into their newest stage of aircraft development to create a new generation of models and possibly the future of aerospace.
"This flying cargo air vehicle represents another major step in our Boeing eVTOL strategy," said Boeing Chief Technology Officer Greg Hyslop. "We have an opportunity to really change air travel and transport, and we'll look back on this day as a major step in that journey."
The Unmanned aircraft have been intended to be able to vertical lift cargo with approximated weight of 500 pounds. The (CAV) prototype is focused on cargo and “logistic applications “for commercial use.
The Boeing team of engineers were able to build the newly composed CAV prototype in little than three months.
Boeing sub diary Boeing Horizon X makes all this possible along with the help of their addition resources Boeing Research and Technology.
This prototype specs have been measured to be:
15 feet long (4.57 meters)
18 feet wide (5.49 meters)
4 feet tall (1.22 meters)
weighs 747 pounds (339 kilograms).
The prototype also includes eight counter-rotating blades that help the prototype be able to shift vertically. Boeing's world renown name will continue to expand as their company begins to shift its focus on what is yet to come in the near future.

The semiconductor company by the name of Broadcom and its associates have prepared themselves for the biggest expansions their company has ever seen. Broadcom has teamed up a private US equity firm, Silver Lake Partners to be place a bid of an approximate 2.2 trillion yen which calculates to be 20 billion US dollars. There has been speculation that Japanese Gov. would have preferred to have a US company bid this appose to a country like South Korea, China or Taiwan.
Broadcom has made a strong decision by progressing without most of its former associates.
“Foxconn with the potential support of Apple; rival memory maker SK Hynix of South Korea; a Japanese-US consortium linked to the state-backed Innovation Network Corp. of Japan; and Western Digital.”
According toToshiba sources it is said to be able have put its memory division up for bid due to a massive write down from their nuclear power business.
Broadcom specializes in creating and manufacturing chips that are used for communications such as semiconductors, controllers, ICs, Embedded and Network Processors and much more.
If the Broadcom bid does follow through they are to venture out into a what is known as the non – volatile memory market. Along with much of their newly integrated material they will be able to drive their way to consumer electronics such as NAND flash that can be found in tablets, wearable electronics and smart phones used today.
Along with the bid there have been some issues that arose with the request of the bid. Western Digital which has been a long partner of Toshiba is claiming that it was not notified or giving the chance to be able to refuse the bid. It was processed without their approval and therefore Western is placing a law suit under breach of contract to restrain Toshiba from selling the memory division.

When flying in an aircraft, there are many safety factors to consider. For the passenger, it is unsettling when they begin to feel turbulence and experience a rocky ride. For the most part, turbulence is not necessarily dangerous. However, there are moments when there can become dangers and threats to the safety of an airplane. One factor is the chances of lightning striking an aircraft. To many people’s shock, aircrafts are actually very likely to be struck by lightning during their flight. Some reports state that active aircrafts will be struck at least once a year around the world. However, we rarely hear of such stories and their impacts on aircrafts.
This is due to the smart aircraft lightning sensors that prevent these strikes from impairing the plane. NASA has implemented new structural health monitoring sensors that will help deflect lightning strikes. With the lightning sensor aircrafts, each strike will be dispersed by the sensors and will help mitigate damages to the aircraft. Although not all lightning will damage a plane, there are some that force an aircraft to undergo repairs and maintenance. These news sensors will allow aircrafts to stay active longer, without having to go to a repair shop to fix any damages caused by the force of nature. Lightning sensor aircrafts will allow for much more durable and safe aircrafts to be used throughout the world, and will hopefully reduce future costs of repairs.
