Acceleration refers to the change in velocity of an object relative to time. According to the relative theory, depending on the relative object taken to measure acceleration, there are two types of acceleration: proper acceleration and coordinate acceleration. Proper acceleration is the physical increase in speed of an object in respect to inertia or the observer who is at rest relative to the object being measured. Coordinate acceleration depends on the choice of coordinate system and choice of observers. The accelerometer is an electromechanical sensor device used to measure the proper acceleration of an object.

A wheel speed sensor, or vehicle speed sensor, is an example of a tachometer. It is known as a sender device and is used to read the speed of a vehicle's wheel rotation. Wheel speed sensors typically consist of a toothed ring and pickup, and are found in automobiles, aircraft, and other wheeled vehicles. This blog will further explain aircraft wheel speed sensors, their characteristics, and how they operate.

Before delving into the complex factors that can affect performance for an RF coaxial cable connectors, it’s important to understand what an RF coaxial cable connector assemblies is as well as their functions. The RF coaxial cable connector assemblies are built up of is actual two RF coaxial connectors and a customi length of a separate RF coaxial cable that is administered through the use of welding. The performance of lone RF coaxial cable is an essential component of the RF coaxial cable connector assembly, and its functionality is highly reliant on  the whole RF coaxial cable connector assembly. For a further look at the RF coaxial cable connector assemblies, read the article below.

There are many different types of aircraft valves that can be used for the aircraft engine. While they each have different physical characteristics and serve different purposes, the aircraft valves tend to operate in a similar fashion. For example, the valves in the cylinders of an aircraft engine must endure severe conditions, including high temperatures, corrosion, and operating stresses. For this reason, metal alloy is often used in most valves so that they can resist and withstand being subject to extreme factors. However, some valves, such as intake valves, must function at temperatures lower than exhaust valves, and can thus be made of chromium-nickel steel. On the other hand, exhaust valves can be built of nichrome, silchrome, or cobalt-chromium steel because these materials are much more heat resistant. For more information on the different aircraft valve types, see below for more information.

When constructing an aircraft or other complex machines that undergo heavy stress during operation, bearings are an extremely useful hardware component to have for assembly. Bearings are mechanical components that mitigate friction caused by parts moving within a system, as well as allow for transfer of axial and radial loads across components. There are various types of bearings that can act for a wide amount of applications, and some examples include the bush bearing, pillow block, thrust bearing, and antifriction bearing (ball and roller bearings).

Within the realm of computing, microprocessors are an integral technology that has constantly pushed the limits of computer hardware and capability throughout their history. At their most basic, microprocessors are integrated circuits that encompass the central processing unit (CPU) and work to translate inputted binary data into outputted data. The amount of microprocessor assembly parts, such as transistors have gradually increased, allowing technological advancement from 4-bit to 64-bit technology over their history, greatly increasing the complex processes that the microprocessor can handle. Microprocessors can also serve a variety of applications, ranging from controlling elevators to operating complex computer systems.

The future of commercial in-flight passenger experience is one of both technology advancements and engineering achievement. With the invention of virtual reality in 1957 to now the most advanced VR headset, the StarVR One, Airbus -- a leading name in the commercial passenger service -- recently patented a Virtual Reality Helmet for its passengers. The helmet will offer sensorial isolation and endless entertainment possibilities that would make the flight time on a normal US coast to coast flight, literally, fly by.

An aileron is the hinged surface in the outermost trailing edge of an airplane wing, designed to control the lateral balance of the plane as it cruises through flight, or during its roll. The ailerons and how they function in relation to the aircraft is something that every pilot and/or aircraft enthusiast should know. Read on below for a basic outline of how the ailerons function.

As a natural side-effect of combustion, piston engines generate large amounts of heat that needs to be managed. An engine’s internal components are cooled by the oil system, but the external components, such as the cylinder heads, need to be cooled as well. While some engines feature water cooling systems and radiators, most general aviation aircraft use air cooling introduced by the cowling at the front of the front of the engine compartment, and a system of baffles within the compartment to distribute air.

With every component that comes together to create an aircraft, it is actually one of the smallest components, the fastener, that remains one of the most important parts to the entirety of the structure. A Boeing 747-800, for example, is comprised of 6 million parts, half of them being fasteners. Much like a fastener that one may find at a hardware store, the part’s functionality at its most basic is to join or affix two or more components together in a non-permanent fashion so that the objects could be later separated. Unlike their hardware store counterparts, however, aviation fasteners are held to a much higher standard, and are specifically engineered with precise specifications to ensure they withstand the demands of high altitude flight. Fasteners are important beyond holding components together, also providing the benefit of taking on and redistributing structural loads.
