Electricity is paramount for powering the countless appliances and electronics that we rely on every day, but it is also a volatile force that needs to be managed for safety. When an excessive amount of current passes through wires due to a short circuit, a great amount of heat may be generated and sensitive components can be seriously damaged. Additionally, short-circuiting can even cause electrical fires and dangers to individuals which can be extremely dangerous for certain applications such as aviation. In order to prevent the damages and hazards associated with overload conditions, electrical circuits are guarded with circuit protection devices. The most common circuit protection devices are fuses, current limiters, and circuit breakers. As each device type has its own features and capabilities that dictate their use, it can be very beneficial to understand the differences between each Fuses are a basic component for circuit protection, and they are a thermal device with an element which exhibits a low melting point. Fuses generally have low current carrying capacities, and they are designed to melt in the occurrence of a short circuit. With this method of operation, fuses can quickly interrupt a circuit for safety. The element of the fuse may be constructed from varying materials, and the most common are lead silver, tin, bismuth, and their related alloys. To provide ample protection for the circuit, fuses must be placed near the power source so that they may manage the entire cable. For aircraft applications in particular, fuses are often heavy-duty and may serve AC and DC sources. Furthermore, aircraft often employ fuses for both the circuit and devices for redundancy and further protection.

With the constant advancement of aviation technology, avionics, and other components, an increasing number of aircraft systems and mechanical functions are becoming more reliant on electronics. Solenoids and relays are two components that may fulfill these needs, as solenoids serve for the electromechanical interface while relays switch the electronic loads for many aircraft systems and devices. As both of these components are used in many modern aircraft, it is important to understand how relays and solenoids work, how they may save aircraft power, and how they provide functionality for various aircraft systems.

In their most basic form, solenoids are components that produce a magnetic field through a wound coil as electric current is inducted through them. Through this magnetic field, the solenoid effectively converts energy into linear motion. Often, solenoids are used as an actuator for a pneumatic or hydraulic valve, or as an electrical switch. As a switch, the solenoid may serve the starter of a vehicle, such as an automobile starter solenoid.

A dock is obviously a necessary for boarding and departing from a boat. In some places, such as rivers, lakes, and reservoirs that don’t experience changing water levels, a fixed dock mounted on posts in the water serves as a stable and functioning platform. However, many bodies of water have changing tide levels, which a fixed dock cannot adjust to. Floating docks, meanwhile, can rise and fall with the tide, making it the logical choice.

Put simply, corrosion is a boat owner’s worst enemy. Sadly, for naval operators, corrosion is a natural process that occurs when  iron and oxygen react in water or react in moisture in the air. As a result of this occurrence, metal materials are weakened and deteriorate over time. Saltwater does not directly cause corrosion but speeds up the effects of corrosion on marine hardware parts. Saltwater is an electrolyte solution and contains more ions than fresh water, so the electrons can move more easily through the water, accelerating degradation.

The structures of a helicopter are designed to give it its unique flight characteristics, such as vertical takeoff and landing, and hovering in place. A helicopter flies because the rotors serve as rotating airfoils that provide lift, similar to how the wings of an airplane create lift. Air flows faster over the curved upper surface of the rotors, creating negative pressure, and thus lifting the aircraft. Changing the angle that the blades meet the wind increases or decreases lift, raising or lowering the helicopter. Tilting the rotor plane of rotation causes the helicopter to move horizontally.

“Switches”, “transmitters”, & “transducers” are said interchangeably with no regards for the differences, but that’s wrong. They aren’t all the same thing. You can’t use a transmitter in place of a switch and expect your circuit to work the way you wanted it to. And one of the biggest reasons you would have used the wrong part is that you thought they were all the same and didn’t know the difference. In order to put an end to the confusion and misuse, let’s talk about the difference between pressure switches and pressure transmitters.
