Seacocks are valves that are placed on the hull of a boat or ship which in order to allow water to flow in or out of the vessel. They can be used for varying applications, including the cooling of engines with sea water to the removal of water from a sink drain. While many individuals may want to use a through-hull fitting, such additions can be risky as they can sink ships if not formed correctly. While a tee connector on an existing inlet is most preferred, there are times in which a new through-hull fitting is either needed or more advantageous. In this blog, we will provide a brief overview of how seacocks are safely installed or replaced on marine vessels.

Turbochargers are among the most advanced engine components of an onboard ship. The impeller blades of a medium sized turbocharger commonly rotate at speeds up to 400 revolutions per second, and the outer edges of the rotor blades therefore move at more than one and a half times the speed of sound. As turbochargers are critical components, it is important that proper procedures for safety and cleaning are always adhered to. In this blog, we will discuss the best practices for safety and turbocharger overhaul & cleaning.

When automobiles began making the shift from manual transmission to those that are automatic, a number of parts and assemblies had to be adjusted to accommodate such changes. In manual transmission vehicles, a component known as the clutch is what connects the transmission to the engine. Without it, the vehicle would face an engine kill every time it came to a stop. With automatic transmissions, the clutch is no longer needed as it is replaced with a component known as a torque converter.

Turbonormalizing and turbocharging engines share many characteristics. They both compress outside ambient air to create engine power, they both use an exhaust driven turbine to power a centrifugal compressor at high speeds, and they can both use the same turbo components. When designing a turbonormalizing system, the manufacturer usually starts with a normally aspirated engine and begs the question: while making the fewest changes, how can I take this normally aspirated engine and make it operate at sea level power at altitudes greater than 18,000 feet? In reality, the turbocharging system was designed based on the same question. The answer, for both, is a list of eight additions to be made:

Screws are a type of fastener that feature a helical external threading that wedges and digs into the component it is installed into as it is tightened. As torque is applied and the screw is driven in, materials are pulled in tightly to prevent easy removal of the screw. Materials that screws are used in can include wood, sheet metals, and plastics. The most common material that is used to manufacture screws is steel, though stainless steel, titanium, brass, bronze, and other screw types are also available. Screws are the most commonly used threaded fastener on aircraft, having many different applications. While many variations of screws exist, they are generally classified in three groups: structural, machine, and self-tapping.

Measuring fuel levels in an aircraft is an incredibly important task. Running out of fuel for an automobile typically means a ruined afternoon; an aircraft running out of fuel while operating, meanwhile, is potentially disastrous. Therefore, accurate and reliable fuel gauges are essential, with the most commonly chosen type in small aircraft being resistive-type fuel systems. In a resistive-type fuel system, a float level gauge feeds information on the fuel level to magnetic couplings and potentiometers that then relay information to the pilot. As fuel is expended in flight and the levels in the tank drop, the float inside the tank drops as well and slides a moving contact a long a resistor, increasing its resistance. The amount of resistance translates to how much fuel is left in the tank.
