Emergency floatation systems (EFS) are designed to prevent a helicopter from sinking or capsizing after making a controlled ditching or water impact. Such accidents are rare, but an EFS can buy time for emergency rescue services to arrive and save the occupants.
Aircraft refueling may be a common and routine procedure, but you cannot afford to be complacent or inattentive. When fueling, you must keep sparks from occurring, and mitigate the damage when they do.
While the idea of the helicopter has existed since 400 BC in China in children’s toys, the first true powered examples were developed in the 1900s throughout Europe. These early aircraft had trouble getting off the ground — literally. In fact, they could only make short tethered flights that lasted a few seconds, as they were unreliable and difficult to control. One issue lay with the main rotor, which, as it spun to generate lift caused the entire fuselage to spin with it.
Before we get into the specifics on the process of wind turbine installation, let us get to know what a wind turbine is. A wind turbine is a mechanism that is capable of converting the kinetic energy produced by wind into mechanical power. This mechanical power can be used for specific tasks, or a generator can convert this mechanical power into electricity. Wind turbines are constructed in varying heights, widths, and lengths according to the application they will be used for. Smaller turbines can be used in lower scale operations, such as powering a home, powering a traffic signal, or charging a battery. Larger turbines are used for industrial purposes, such as providing a source of renewable energy to support a power grid.
In the aviation aftermarket spares industry, original equipment manufacturers (OEMs) and part manufacturer approvals (PMAs) are in competition. Of course, there are maintenance repair and overhaul (MRO) businesses and parts distributors, but when it comes to making the parts, competition is between the former two. Originally, OEMs had a monopoly on parts, but the Federal Aviation Administration (FAA) approved manufacturing PMAs and drove high prices down through competition. Although the FAA has made it clear that PMAs are just as safe as OEM parts, some are still skeptical.
The metal-oxide-semiconductor-field-effect transistor (MOSFET) is a field-effect transistor which is often created by the controlled oxidation of silicon. A MOSFET is a semiconductor device which is most commonly used in power electronics. A semiconductor is composed of a material that doesn’t act as an insulator or a conductor and both of these properties can be controlled. A transistor is a bipolar device that is created by combining a positive and a negative material. It has three terminals: the collector, the emitter, and the base. MOSFETs are bipolar, but metal oxide insulators are added to enhance performance. The terminals in a MOSFET are called the source, the drain, and the gate. “Field effect” describes the method that is used to control the current flowing through the device. In a MOSFET, as the temperature increases, its ability to conduct current decreases. It creates a natural balance because if one device begins to create more current, it will heat up and cause the current to decrease and both devices will level out.
Technology is on the rise everywhere, in every industry, enhancing every aspect of life. So, it might come to no surprise that huge technological advancements are expected to arrive at airports and airlines within the next year, aiming to make the entire flying process, from check-in and boarding to baggage claim and in-flight purchases easier and more convenient. Some of these advancements include biometrics, blockchain technology, artificial intelligence, robotics, electronic baggage, translation applications, and augmented reality.
In aerospace and aviation safety, safety is the singular most important thing. In order to ensure safety as much as possible, every step of the aircraft’s life is strictly regulated. In order to do this, the aviation industry enforces traces.
Earlier in July, Cornell Dubilier Electronics released their newest film capacitors for uninterrupted power supplies (UPS), AC power supplies, and general AC filtering applications, the 951C Round Axial Leaded and the 935B Radial Leaded Box Metalized Polypropylene Film Capacitors. The 951C has a cylindrical body with axial 18 AWG tin plated wire leads, and the 953B has a rugged radial box form with four 16 AWG wire leads. Sizes for both vary depending on value. Both capacitors show strong performance in filtering in applications where high-ripple currents are encountered and benign end-of-life failure mode is crucial.
Solenoid Control Systems is for endurance and cycling testing for electro-mechanical components to include Industrial motors, actuators, electromagnets, and relays. These tests are vital to the testing process to make sure components are working properly. The announcement of Optimal Engineering’s seven new Solenoid Control Modules aims to make Solenoid Modules to fit many different applications. Standard features of the modules are they are microcomputer focused, high output, and include a flyback diode in each unit. The ability to use these Solenoids in focused roles make for extreme value to the user.
