Aircraft feature numerous structures that regulate different components necessary for their operation. For example, aviation hydraulic systems assist planes while they take off, fly, and land. Though pneumatic systems may also be used, aviation hydraulic systems tend to be popular because they are far more reliable than any alternative, and they offer an ideal amount of pressure for particular aircraft operations. As such, they are used to operate aircraft equipment like the brakes, thrust reversers, flight controls, and landing gear. Moreover, hydraulic systems are preferred for their tendency to use non-compressible liquids, meaning that they do not cause a delay in movement, as is the case for pneumatic systems. The following article will explore hydraulic systems and the advantages of using them.
Marine diesel engines are internal combustion engines that use heavy fuel oil and compressed air to generate power. Within the larger system, the main engine is used for propulsion while the auxiliary engine generates electricity for the ship. Additionally, marine diesel engines work on the principle of the dual combustion cycle; similar to engines used in many modern cars, this may include a four-stroke cycle involving intake, compression, power, and exhaust. However, due to the combustive nature of heavy fuel oil used in diesel engines, the combustion cycle may also be confined to two strokes wherein the compression of hot air and diesel fuel is enough to cause the mixture to self-ignite.
Modern electronic assemblies are often quite complex, featuring a wide variety of parts that work together to establish functionality. Many of these various parts are often known by acronyms to simplify discussion, though this can cause issues when acronyms and parts are fairly similar to one another. An example of this is the printed wiring board (PWB), that of which may be conflated with a printed circuit board (PCB) as a result of their close names. Despite this, there is a difference between the two, making it important that one has a basic understanding of printed wiring boards, their design, and their use.
As the marine propulsion systems/engine market is gaining considerable traction for the ability to power massive cargo ships, it is only becoming more apparent that the demand for these sustainable engines is on the rise. Marine propulsion systems propel ships through water, ensuring a better safety standard for the marine ecosystem and cost efficiency. With the intent to fight pollution, worldwide emission reduction goals have been set for the maritime sector that can be achieved with such systems.
A generator is an important device for producing electrical energy through the conversion of mechanical energy by means of electromagnetic induction. Generators vary in design and components; however, specific types of generators will contain the same basic components. For this blog, we will be focusing on key parts that make up an AC generator, also known as an alternator. When in use, this type of generator converts mechanical energy into AC voltage and current, and it differs from a DC generator in its use of alternating current rather than direct current. The basic components of an AC generator include field windings, an armature, slip rings, and brushes.
Engines, or motors as they are sometimes called, are complex machines that convert one or more forms of energy into mechanical energy. They find use in countless apparatuses, allowing systems to run optimally. Furthermore, they vary based on use, each featuring distinguishing characteristics. Marine engines in particular are just one type of motor that has a unique way of converting energy and generating rotation.
There are various wing flaps on the market that are necessary for flight and other aerobatic features for aircraft. In addition, engineers work to take advantage of wing flaps to efficiently increase the movement capabilities of an airplane, whether it be a jet or propeller-driven aircraft. Affixed to a majority of aircraft to make their flight more efficient, flaps help aircraft produce more lift and drag, directly affecting the landing and taking off roll. Although some airplanes can fly without wing flaps, such as light sport or training aircraft, they are still responsible for the efficient flying of most planes. In this blog, to better understand flaps, we will be going over their most common types.
When operating a fluid system, it is crucial that there are means for fluids to optimally move between reservoirs, power sources, and other areas. With the use of fluid lines, fluids may be transported wherever needed, and fittings serve as the connection points for each line. As hydraulic fluid lines and fittings may vary in their type, shape, material, and more, it is important that one is familiar with the basics of such components before they make a purchasing decision.
While you may have heard of a drivetrain, you may not be familiar with how it works. The term is often used interchangeably to also refer to powertrain or driveline equipment. A drivetrain includes the transmission, driveshaft, axles, and wheels. With this in mind, the drivetrain works in tandem with the engine to rotate the wheels. As movement is a vehicle’s primary function, the drivetrain system is an essential component to such structures.
Screws are a common fastener used for the assembly of parts, typically being used for wood, sheet metal, and plastic. Screws are notable for their helical ridge, allowing them to be self-threading as they are driven into a surface and pull materials together. In order to install a screw, one needs a tool that matches the head of the fastener. Screw heads can come in numerous styles, those being chosen for a functional or decorative purpose. In this blog, we will discuss the primary types of screw heads, allowing you to better understand how such fasteners are used.
