A piston engine is a powerful apparatus, capable of harnessing the pressure of combusted fuel-and-air mixtures to generate a rotational movement. In order for proper combustion and operations, piston engines require minimal loss, efficient heat transfer, and much more. With a metallic split ring known as a piston ring, the gaps between the piston and the cylinder wall may be sealed for the protection of the engine assembly and its performance. There are also multiple types of piston rings, each of which may be implemented in varying areas of the assembly to provide different functions.

While marine vessels are less constricted in their range of operation as compared to other forms of travel such as automobiles, there are still plenty of rules and guidelines that should be followed to maintain safe operations on the open water. Similar to the traffic lights and stops that dictate how we drive, buoys, beacons, and lights are the primary navigation tools that assist vessels in their operations. Such items can come in a variety of shapes, sizes, and colors, many having distinct meanings that can be very useful for proper navigation. In this blog, we will provide an overview of the buoys, beacons, and lights that serve marine navigation, allowing you to better understand how to conduct safe operations on the open water.

Cowlings are removable covers that are used for aircraft engines in order to reduce drag and increase cooling for temperature control. Despite their importance for the overall performance of the aircraft, cowlings are often structures that are not given the attention they deserve. When one needs to install a cowling on their aircraft for a repair or for the first time, it is crucial that the cover is shaped to the installation or adjusted to optimally fit. As such, proper cowling installation should always be carried out.

Relays are a type of electrically operated switch, and they provide input terminals and operating contact terminals for their functionality. Depending on the relay, they may be implemented within a device in order to control a circuit with a low-power signal or several circuits with a single signal. In their infancy, relays served as signal repeaters for long-distance telegraph circuits as well as telephone exchanges. As more advancements were made to such electrical switch components, their applications widened to include a number of electronic systems and appliances for motor control, circuit protection, safety-critical logic procedures, and more. While a number of relays exist to facilitate numerous needs, the three primary types that are most often used include the electromechanical, solid-state, and reed relay.

The marine diesel engine is an advanced apparatus, allowing for the combustion powered operation of vessels on water. Generally, a marine engine may either be inboard or outboard, meaning that the engine may be implemented within the hull of a boat or mounted upon the hull itself. Regardless of which type of diesel engine is present on a marine vessel, many share the same components and systems that allow them to operate efficiently.

Unknown to a majority of people outside of aviation, manufacturing, and industrial space, an air capacitor is a type of capacitor that uses air as a dielectric medium which is placed between conductive plates. Or in basic terms, they are capacitors that utilize air as a dielectric, with the most simple form being one that is made of two conductive plates separated by an air gap. As for the way that they are manufactured, air capacitors can be produced as either a fixed or variable. The difference between fixed capacitors and variable air capacitors is that the latter are often applied more than the former because it has a simpler makeup. In contrast, the air capacitors are hardly used since there are many other types with superior characteristics. For more information on air capacitors, read the article below.

Air bearings, also known as aerostatic or aerodynamic bearings, are fluid bearings that use a thin film of pressurized gas to provide a low friction load-bearing interface between surfaces. The two surfaces do not touch, thereby avoiding the traditional problems associated with bearings such as friction, wear and tear, particulates, and lubricant handling. Instead, air bearings offer advantages such as a lack of backlash or static friction and high performance in high-speed applications. In aerospace, friction is a common problem encountered in nearly all operations. Air bearings are critical in reducing friction and preventing serious damage caused by it. This blog will explain the main benefits of air bearings as well as their four main applications throughout the aerospace industry.

Just like an aircraft, automobile, or any other vehicle, a boat will inevitably need repairs after certain intervals. Repairs will usually require the ship to dock, but depending on the severity of the repairs, they can also be done at sea assuming a support vessel has the necessary equipment, parts, and repairmen capable of carrying out the task. There are three categories of marine repair: electrical and mechanical repairs, marine engine repairs, and emergency response repairs. This blog will explain each type and what they entail.

The marine radar of a ship is useful for providing the captain and crew awareness of other ships and land obstacles that are surrounding them during their voyage. Detection is achieved through the radar emission of a radio signal which bounces back to the radar when it comes into contact with another marine vessel or object, thus providing an estimate of surrounding targets. With this reading, the captain and crew can then enact collision avoidance and properly navigate the ocean safely.

Before deciding whether or not you need to repair any broken propeller for your boat, it is important to first establish if replacing would be a better option as opposed to doing propeller maintenance work. You can figure this out simply by asking yourself if the propeller kept your motor in the correct rpm range. Did the boat using the propeller accelerate well? Did you notice vibrations from the propellor when taking out the boat? If you answered yes to any of these questions, then a replacement might be better than trying to repair the propeller.
