A bearing is any surface that supports or is supported by another surface. A quality bearing is made of material strong enough to withstand the pressure it is exposed to while permitting the other surface to move with minimal friction and wear. The bearing must be held tightly in position with close tolerance to provide efficient and quiet operation, yet still be allowed to move freely. To do this while reducing friction and power loss, aircraft engines employ many different types of bearings.

A smoke detector is a security device that senses smoke to indicate the presence of fire. Commercial smoke detectors send a signal to a fire alarm control panel as part of a greater fire alarm system. Household smoke detectors, on the other hand, typically issue a local audible or visual alarm from the detector itself or several interlinked smoke detectors. While smoke detectors are found in every building, few people are familiar with how they work. This blog will discuss how smoke detectors work and how to get the best out of yours.

While many may be familiar with remote-piloted aircraft (RPA) drones as a technology for hobbyists and enthusiasts, such technology has rapidly expanded in popularity and use in recent years, permeating multiple consumer, government, and enterprise sectors. From providing aerial shots for photography to locating missing persons during a search and rescue operation, drones are quickly finding more use as they continue to develop. To understand drones and the future they pose, it is important to be aware of the various materials and parts that they are composed of.

Keysight Electronic Calibration (ECal) Modules are state-of-the art, solid-state devices with programmable and highly repeatable impedance states that are traceable through the National Metrology Institute (NMI). ECal modules are controlled by the Keysight network analyzers, meaning no external PC is required. Electronic calibration replaces the need for traditional mechanical standard calibration, and provides reliable calibration that eliminates outside factors like operator error, all while making the calibration process more simple and convenient.

A signal generator is any type of device that can create an electronic signal in the form of a wavelength. Oftentimes, they’re used for development and test systems within other equipment designed for assessments. There are various types that you can find in the current market, but each serve the primary purpose of producing an electrical signal. Some very common generators include vector signal generators. signal generators, and arbitrary function generators.

Although aircraft functions differ greatly based on their design, their basic structures are all roughly the same. While there are many subcomponents, there are really only five major aircraft components: the fuselage, wings, empennage, powerplant, and landing gear.

Relays are electronic control devices that pair a control system (or input loop) with a controlled system (or output loop). They are typically used in automatic control circuits, with a smaller current to control a larger “automatic switch” of current. Relays are used in the role of automatic adjustment, safety protection, and conversion circuits.

The term “thermistor” is a combination of the words thermal and resistor. Negative Temperature Coefficient (NTC) thermistors are components within an electric circuit that lose resistance as they come in contact with increasing temperatures. They are widely used as temperature sensors in applications varying from microwaves to computers to the seat heater in your car. Not only do they measure temperature, thermistors also measure liquid levels, making their use in mechanical systems invaluable. What's more, NTC thermistors can operate between -55 to 200 degrees Celsius making them suitable for a variety of environments on an aircraft.

The first U.S. patent for the o-ring was filed in 1937 by Niels Christensen. During WW2, the US government deemed it as a critical war-related item and therefore transferred the rights to manufacture it to many other organizations. Christensen received a payment because of this, but 20 years after his death, his heirs received another large payment due to litigation. With how important and commonly used o-rings are today, maybe the payments would be even bigger.

An alternator is an electrical generator that converts energy into electricity in the form of an alternating current (AC).  An automatic drive controls the alternators rational speed allowing for the alternator to maintain a constant output. All AC alternators are required to rotate at a specific speed to keep the frequency of the AC voltage within proper limits. If a frequency strays more than 10 percent from the required value, the electrical system will not work properly. To ensure an alternator always stays within values, a unit called a constant-speed drive is used. This unit always rotates at the correct speed and can be mounted independently or within the alternator housing. This unit is comparable to an automatic transmission found in an automobile; the engine can change but the speed remains constant.  In an aircraft, the hydraulic transmission is mounted between the AC alternator and the engine. Hydraulic oil is used to operate the transmission allowing for a constant output speed and engine rpm drives the hydraulic pump, turning the alternator.

Air compressors are the most common machine in a number of industries, from aerospace and aviation to construction and manufacturing. And because they’re used to power a lot of different machines like paint guns, pressure washers, and sandblasters, it’s important to know the differences between air compressors and know what kind you need for your project.

In February of 2015 at the US Air Force Association’s Air Warfare Symposium in Florida, Lockheed Martin introduced its fifth-generation targeting and tracking system, dubbed the Legion Pod. The company claims that the Pod can be retroactively fitted onto older aircraft, giving them new infrared search and track (IRST) capabilities. According to company specifications, the Legion Pod is 98.5 inches in length, 16.0 inches in diameter, and weighs under 550 pounds.

For sensor systems, the Pod will use the company’s IRST21™ infrared sensor in combination with network and data processing technology to track airborne targets and communicate situational awareness information to allied aircraft. With development beginning in 2012, the Legion Pod was intended to primarily support the F-15C Eagle and F-16 Fighting Falcon fighter jets but is also configurable to numerous other aircraft platforms as the device is a modular design with line-replaceable units and an open “plug-and-play” architecture, meaning it can be transferable to any aircraft system. In addition, as a result of its infrared-based sensor, the Pod has the ability to remain hidden from radar detection while tracking and collecting target information. The Legion Pod was first operational onboard a select number of F/A-18E/F Super Hornets from the US Navy, but the Pod should be able to establish network communication among both legacy and next-generation aircraft.

The technology may also be a viable choice for a planned multi-domain adaptable processing system (MAPS), a project to enable communication between stealth aircraft.

In February 2015, the French telecommunications company Sagem installed their new navigation system on the French Navy’s nuclear-powered aircraft carrier, the Charles de Gaulle. Done as part of a refit program, the upgrades were completed by the project management of the French government’s defense procurement agency, the Direction Generale de l’Armement. DCNS took the role as the prime contractor of the project in which Sagem supplied several different equipment systems such as the navigation system, alignment system, intelligence system, and several landing aids for the refit.
