For modern aircraft engines to efficiently create enough power for thrust and lift, they rely on the ingestion of atmospheric air that is subsequently mixed with fuel to enhance its combustive properties. As it is essential for there to be a supply of air while ensuring proper mixing, assemblies known as induction systems have been developed and enhanced over time. In this blog, we will discuss induction systems and their common types in brief detail, allowing you to have a better understanding of their functionality and use.
Generators are a common form of equipment that may be found in a diverse set of industries and applications, allowing for harnessable electricity to be generated. Generators generally come in one of two forms, those being direct current (DC) or alternating current (AC) variations. While both of these options rely on the principle of electromagnetic induction to carry out their duties, the exact processes that they follow differ. In this blog, we will provide a brief overview of DC and AC generators, allowing you to have a better grasp on their similarities and differences.
Across many industries, fasteners are used to secure parts of machinery and other components in place during operation. From screws to nuts, bolts, and so much more, there are countless types of fasteners available on the market, all of which function differently. Deciding which fasteners to use for your applications can be tricky, so it is helpful to understand the general designs and functions of some of the more popular fastener types. For your better knowledge, this blog will explore both nuts and nutplates, two separate types of internally threaded fasteners. With similar names but different advantages, it is useful to be able to distinguish between the two when deciding which to procure for your operations.
With the ability to cover massive swaths of land at unparalleled speeds, many modern aircraft rely on the jet engine to generate the great amount of power required to propel 700,000 pounds of aluminum through flight. Jet engines, or gas turbines, on modern aircraft are more often than not turbofan engines, those of which use a combination of combustion and bypass air to create thrust. As the majority of aircraft today rely on the turbofan engine, this blog will explore the unique features and functions of this specific turbojet which set it apart from older designs.
When working with aircraft that feature propeller assemblies, one may notice that each propeller blade features a twisted design. This is an intentional choice during the manufacturing stage, ensuring that blades are able to most optimally perform during flight. To help you better understand this design choice, you will first need to be familiar with the physics of propeller assemblies.
While some may think firewalls are limited to the automobile world, they are actually an integral part of aircraft as well, acting as barriers between an airplane’s engines and the rest of the airframe. Commonly known as bulkheads in the United Kingdom, firewalls are considered a fire-resistant barrier. To better understand their purpose and function, this blog will provide a brief overview of firewalls in aircraft.
While the terms fuselage and airframe are often used interchangeably to refer to the body of an aircraft, they are technically not the same. In fact, the fuselage is a portion of the airframe that includes the middle section of the aircraft but excludes the wings and other extended features. Understanding the technical differences between the two structures is important for anyone operating aircraft, so this blog will delve into the distinguishing features that define each term.
The word “tachometer” is derived from the Greek words “tachos,” which means speed, and “metron,” which means “measure.” However, contrary to what the name may suggest, tachometers do not necessarily track the speed of an aircraft, but rather, they measure an engine’s operating speed in revolutions per minute (RPM). Tachometers indicate the mechanical motion of either the entire aircraft or one of its components. They measure the rotational speed and the angular (aka rotary) velocity of either the disc or the shaft of the rotating body.
Shaft couplings are mechanical elements that join two shafts together and help in accommodating the misalignment of torque from one end to another. These mechanical devices are used for connecting rotating shafts and absorbing misalignments between them. Depending on the alignment precision of the torque and system requirements, couplings can be flexible or rigid.
Some of the most common applications of shaft couplings are for torque and power transmission between rotating shafts, like in compressors, generators, and motors. There are many types of couplings that one may procure as well. Let us have a look at the most common types of shaft couplings.
Washers are machine components that find use in countless assemblies. Typically used in conjunction with a screw fastener such as a bolt and nut, washers keep such components from loosening. More than that, they distribute the load from the nut or bolt head over a larger surface area, reducing wear over time.
