Heat is produced in an engine primarily through the combustion process— when fuel and air is mixed and burned to produce heat energy that is converted to mechanical energy for rotation or to produce high-pressure exhaust. The material that is used to construct an engine has high heat capabilities, however, excessive heat can cause serious damage or failure to an engine.
Most aircraft powerplants dissipate about half of their produced heat through the exhaust and remaining heat is absorbed by the engine. Excessive heat is undesirable because it changes the process that the combustion chamber utilizes, creates excessive wear on engine components, and impairs lubrication. In order to prevent the detrimental effects of overheating, engines contain cooling systems. They vary in complexity depending on the specific engine and how much heat it produces.
Reciprocating Engine Cooling
Reciprocating engines are either cooled by passing air over the cylinder fins or through liquid coolants. Oil that is circulating through the engine picks up some of the heat and transfers it to the airstream through an oil cooler and the rest of the cooling system handle the remaining excess heat. In order to cool an engine, heat needs to be transferred from the cylinders to the air. Cooling fins are used to do this. If too many of the cooling fins are broken, the cylinders need to be replaced to prevent hotspot development. Cowlings and baffles force air over the fins and the baffles have built in blast tubes to direct cool air on to the rear spark plug elbows of each cylinder. This stream of cool air prevents the ignition leads from overheating.
Because an engine needs to stay within temperature ranges, whether it’s becoming too hot or too cold, it needs to have components that control the heating and cooling properties. This is why cowl flaps are used to control cooling. Cowl flaps are extended to cool the engine. Controllable cowl flaps aren’t necessary when the cowling has openings at the nose. Air may be taken in by the holes to cool the engine.
Turbine Engine Cooling
Turbine engines have a continuous combustion process and produce very high levels of heat. They require a more sophisticated cooling system. A large surplus of air is used to begin cooling off a turbine engine. The turbine blades end up absorbing a lot of heat and are usually the hottest area. Because of their conductivity, they pass heat to the outer skin of the engine. Center tubes are used to direct cool air into the center of the burner to increase combustion efficiency and dilute the hot gases before they enter the turbines. The turbine case, bearings, and turbine nozzle are cooled by cooling-air inlets that are on the exterior of the engine. The fan air is used to cool off the engine and its nacelle.

Most of us have driven or been in an old car at some point in our lives. Whether it was the hand-me-down car you got from your parents for a 16th birthday, or the menace-to-society that a first date rolls up in, being in an older car with torque problems can be a bit scary.
Torque converters transmit, or multiply, torque generated by an engine. Automatic transmission cars use torque converters because they allow the engine to keep turning while the wheels and gears in a transmission come to a stop. Manual cars achieve this with the clutch. Some cars, buses, trucks, forwarders and other heavy-duty vehicles, and marine propulsion systems use torque converters. There are four components inside a torque converters housing: the pump, turbine, stator, and transmission fluid.
There are a few common scenarios that cause torque converter problems— matching it with a non-stock engine that it wasn't designed for, exceeding its towing capacity for a prolonged period of time, and containing old and worn components. Overloading a converter can cause overheating, stator clutch seizure, stator clutch breakage, blade deformation and fragmentation, and ballooning. Some of the other common causes are damaged needle bearings, damaged torque converter seals, damaged torque converter clutches, or a malfunctioning torque converter clutch solenoid. There are many signs that show up when a converter is causing trouble.
Vanes will bend as a converter begins to wear. A sign of this problem is when the engine begins revving higher than normal but regulates once it heats up. When an engine block begins shaking at the slightest acceleration, otherwise known as a torque shutter, the converter is faulty. Some of the other signs are less power when driving at lower speeds, a whirring sound at startup, increased stall speed, and the “death sound” which is a loud clacking or grinding noise.
Torque converters can be repaired; however, if a converter has sustained heavy damage it can be safer and more cost-effective to have it replaced.

Elliott Aviation has designed a Prizm brand LED lighting system as well as an electronically dimmable Smart Vision Shades system. Elliot has been granted a Supplemental Type Certification (STC) to use these both systems on aircraft. The lighting and shade systems are currently being manufactured and will be available for use by early 2019 for approved dealers and aircraft manufacturers. The STC installation for both systems was done in a Cessna Citation Excel.
Both the LED lighting and Smart Vision dimmable shade systems can be controlled through the Prizm app. The cabin controller can also control the lighting system. However, the Prizm app includes preset lighting conditions for customers to use and enjoy. The multi-color LED lighting features full-color spectrum mood lighting. It can also be used for upwash, downwash, windows, cup holders, the galley, and more.
The Smart-Vision Shades uses electronic dimmable film on the interior of the plane's windows. It is available in five different colors. Window films have the ability to be controlled individually as well. These films are capable of blocking 99 percent of UV rays.
According to Mark Wilken, the Vice President of the Avionics Programs and Operational Logistics for Elliott Aviation, aircraft repair stations, and refurbishment stations have been looking for a solution that is both well-designed and cost-effective for LED lighting and electronically dimmable window shades. He also states how these systems
"are easy to use, easy to install, and will be available at a price point that is affordable to the end-user."
It's expected that both systems will be very popular with business jets like the Cessna Citations.

Drones are a very cool new toy, giving us new perspectives and access to the most amazing sights we’d normally not have access to. They're also a very problematic one, quickly raising a lot of concerns about boundaries and privacy leading to a flurry of regulations passed by the FAA. As a result, the National Academies of Sciences, Engineering, and Medicine (NASEM) is now claiming that drones are too heavily restricted by the FAA.
According to statistics, there are now more than 1 million drones in the United States. Commonly seen used for recreational/civilian purposes, drones also find use in the commercial and military industries such as for filming or for delivery strikes in areas where flight is considered too risky or difficult.
Tourism companies use drones to film travel destinations, record videos of resorts and post content on social media. Since drones can be operated for different purposes, the U.S Federal Aviation Administration (FAA) has some regulations for them. The FAA requires all commercial drones to remain in the pilot's visual line of sight, and they can only be operated during the day or with proper lighting.
More importantly, the FAA requires pilots of commercial drones to have an airman certificate issued by the FAA. Based on the FAA criteria and regulations, a new report was published by the NASEM questioning the efficiency of the FAA's commercial drone regulations. The report points out that the FAA uses the same approach to regulate commercial drones as it does with commercial airlines, an unnecessary and excessive approach that offers no real safety benefits.
The FAA takes an extremely cautious approach to create safety regulations. But the problem is that drones aren't like commercial airlines; they don't pose the same risk of injury or death. Instead, NASEM suggests that the FAA should be worried about more tangible hazards than commercial drones. The FAA responded saying that it is working to improve its drone regulations, but there's been no word as to what changes, or how or when they'd be implemented.
At One Click Purchasing, owned and operated by ASAP Semiconductor, we know that drones are quickly proving to be a significant and tremendously useful piece of tech.

“Anti-friction bearings”, otherwise known as rolling contact bearings, are those with low friction between the ball and inner and outer rings and are used for both radial and thrust loading. As a cheaper and easier to maintain bearing, they are very common and have a lot of different applications. Rolling contact bearings are divided into two different categories, ball bearing, and roller bearing, and from there they are further categorized by their features.
Common ball bearings include thrust ball bearings, deep groove bearings, angular contact ball bearings, and self-aligning ball bearings. Thrust ball bearings can only support thrust loads in one direction and no radial loads. Deep groove bearings can support thrust loads in both directors and no radial loads. Angular contact ball bearings can handle radial loads and large thrust loads in one direction. Self-aligning ball bearings are used when the alignment of the shaft and housing are problematic, they can handle only lower axial loads since the angle is small.
Common roller bearings include tapered roller bearings, needle roller bearings, spherical roller bearings, cylindrical roller bearings, and wheel hub bearings. Tapered roller bearings use tapered inner and outer rings in order to support thrust and radial loads. The ratio of thrust and radial loads is dependent on the angle between the roller and bearing axis. Needle roller bearings are usually used when radial space is limited. Spherical rollers are able to handle both axial and radial loads as a result of the angular contact between the rollers and raceways. They can also handle shaft misalignment as a result of the double set of rollers. Cylindrical roller bearings are used for large radial loads. And wheel hub bearings are used for the automotive industry to support the massive radial loads caused by the weight of automobiles.
While roller bearings are cheaper and easier to maintain, it does not mean that they do not need to be serviced and replaced regularly. In fact, because of the many applications of bearings, it’s important to check that all your bearings are still functional and safe to use during routine checks and inspections.

The role of power protection devices like Uninterruptible Power Supplies (UPS) have become more important as digitization has a big impact on the layout of global business. Business worksites such as factories, data centers, refineries, and much more, rely on a consistent stream of power to stay operational. Depending on the industry, over millions of dollars can be lost for every hour the system is down. UPS are utilized to avoid any power-outage related problems. They serve as the connector between utility power and generator power.
There are two UPS categories, static and rotary UPS. Static UPS is called “static” because the power path has no moving parts. The rectifier within the static UPS converts the arriving AC current to DC. The inverter then converts DC back to AC to give the load. The DC current combines with the energy storage medium. In common batteries, this charges the batteries and gains power from the batteries when the UPS fails.
The rotary UPS is called “rotary” because due to the rotating components inside the UPS. These components are used to transfer power to the load. Rotary technology has been used for quite some time and gained attention when loads commonly showcased a lower power factor and high harmonics. The low power factor leads to increase loss in the power distribution system which leads to an increase in energy cost. High harmonics shortened the life of both transformers and capacitors prematurely. Users often experienced dimming of lights when large motors were turned on. These characteristics destabilized the electronics of connected loads of the electrical network.
Rotary UPSs are best for environments distinguished by several short inrushes of power. One example would be an environment where multiple motors are turning on and off constantly. An example would be satellite and broadcast stations. Static UPSs provide much wider and broader use. Static UPS has a much more dominant presence than rotary UPSs, the main reason being that of installation cost and efficiency.

Established 65 years ago, Israel Aerospace Industries (IAI) is the major aerospace and aviation manufacturer for both military and civil customers in Israel. The company is completely owned by the government of Israel. IAI’s principal priority is aviation and high technology electronics, additionally it manufacturers military systems for ground and naval forces.
IAI started creating green energy solutions for the future evolution of electrically powered aircrafts, integrating environmental advantages along with longer ranges, toleration and remarkable fuel cost savings. Estimated to fly around in three years, Israel Aerospace Industries will develop an all – electric aircraft.
Details about the project are kept confidential, but IAI revealed that the new aircraft will have a limit of take – off weight of 4530 – 6800 kg, also it can be compared with the size of a Beechcraft King Air 350. The aircraft’s main duty will be inter – city operations, with a range of 500 nm, opposed to 1800 nm for the King Air.
Moshe Medina, vice-president and director of IAI's engineering and development division says,
“The aviation world is about to enter a new era of electric propulsion. The rapid development of electric power sources is accelerating in the cellular worlds and electric vehicles, along with a significant improvement in the reliability and efficiency of electric motors, making the electric plane the next thing in the world of aviation”.
In the last few years, IAI has been investing in the research and development of electric power systems for automatic aircrafts.
Israel Aerospace Industries is contemplating prospective collaborations with beginner companies to work together in the evolution of electrically powered aircrafts.
Earlier this year, Kaman Aerospace Corporation, based out of Bloomfield, Connecticut, made the announcement that they have placed the largest order on Joint Programmable Fuzes, to date. The order totaled in at three-hundred and twenty-four million dollars and will be delivered over a four-year span, between 2019 and 2022.
Kaman Corporation is a multifaceted organization that has been in the aerospace business for more than fifty years. While they are known mainly for their work with aerospace centric bearings, they produce and manufacture a multitude of products. They have service centers all over the nation and have a whopping five distribution locations as well. While their specialty is in aerospace, they also offer products for a horde of other industries.
This purchase, combined with other orders that Kaman has placed in the same general time period, has made their purchase total over five-hundred million dollars. While this may seem like an incomprehensible number, it makes sense when you think about the value that the JPF’s hold. JPF’s are a key factor in the construction of explosive systems that are used by every branch of the military, worldwide.
Since 2002, Kaman has been the only company who can supply JPF’s to the US Air Force, as well as to twenty-six additional nations and organizations. The flexibility of the fuzes mean they can be utilized in hundreds of different ways. Whether that is in different kinds of bombs, multiple styles of planes or alternative weapons.
