Air bearings, also known as aerostatic or aerodynamic bearings, are fluid bearings that utilize a thin film of pressurized gas to provide a low-friction, load-bearing interface between two surfaces. The two surfaces do not touch, therefore avoiding the traditional problems bearings face such as friction, wear, particulates, and lubricant handling. These differ from ball bearings, where the balls are in constant contact with one another and form a solid bridge between the machine elements. Air bearings offer a number of distinct advantages in precision positioning and high speed applications, where they lack backlash and static friction.

Typically, a specific but basic light pattern is required of most marine vessels so that they can be used to show other boats where they are positioned during foggy weather and can among other things prevent boat crash incidents. In the same way that aircraft must have a specific set of patterned lights that alert neighboring aircraft of their position, so too do boats and other marine vessels have various navigational marine lights. For more information on this, read the article below. 

There are several methods that can be taken with fire prevention and fire protection. Some simple yet complex methods include the water sprinkler systems. The water sprinkler system is a required necessity in any building as not having one could significantly impact fire prevention in a scenario where it would be desperately needed. Though they are an essential item to have in any building, it is also essential to understand the systems involved as well as some of the advantages and drawbacks of every material that ought to be assessed before installation. In this article, you can find more information for that below. . 

When it comes to construction, early bridges and aircraft are similar in that a number of rivets are used for assembly and for securing infrastructure. In more recent years, many bridge builders have turned to welding instead, forgoing the rivet for new techniques. Despite this, aircraft continue to be manufactured with the use of aircraft grade rivet technology. This is due to the specific stressors and operations that aircraft undergo, requiring rivets to remain safe and intact.

The design of a steam turbine is a very complex endeavor that requires in depth knowledge from many fields of engineering. The development of such a machine is a big investment that is important and crucial for the current economy climate. Micro gas turbines and steam turbines will continue to be present in the industrial manufacturing and aviation sector. The technological innovations currently being developed will continue to improve the efficiency and longevity of steam turbines. For a basic look on micro gas turbines and steam turbines, read on below. 

We’ve discussed aviation lighting when it comes to commercial flight, but what we have not yet gone over are the lighting signals that can be found on helicopters. While a red and green light on a plane might mean one thing, it can signify something totally different on a helicopter. Read on below for more information on the lighting that can be found on helicopters. 

Aircraft deicing is somewhat similar to how one might deice the windows of a car before driving. In concept they are the same, but in practice is where you start to see the differences. To understand those differences, it’s best to first establish what aircraft deicing is and why the need for aircraft deicing systems parts is so important. Aircraft deicing is a procedure involving the heating and applying of deicing fluid onto the aircraft windows and wings. The need is important because this procedures allows for the safe removal of ice or snow that has been frozen onto the aircraft and, if not removed, could compromise the safety of its next flight. 

As electricity has become an integral part of our modern society, managing and distributing it safely is extremely important. If left unprotected or uncontrolled, electricity can be dangerous and damaging to structures and people. With these posed risks, securing and handling electricity correctly is critical. From the distribution system to each outlet in a house, there are a variety of safety devices and mechanisms in place for protection. Switchgears are a very important safety mechanism that hold features that can benefit a wide variety of applications.

Motor soft starters allow an engine motor to start in low voltage conditions which allow for reverse control operations or multiple speed capabilities; this offers protection from overload faults and over currents. Normal motor starters (direct-on-line technologies or DOL) apply full current, voltage and torque immediately to the motor upon ignition. This basic form of motor starting increases stress on the shaft, motor and electrodynamic stress on the power cables and overall the entire electrical distribution network itself. The importance of a soft starter is to manage this voltage and in doing so protect the longevity of the electrical network and prolong electrical stability and quality. 

When moving into a new residence or building for business, having a sufficient understanding of the installed electrical system can be very beneficial for when problems and issues arise. When needing to conduct repairs, reset breakers after a trip, or respond to any complication, familiarity with the circuit breaker is a crucial first step. This is due to the fact that the circuit breaker is what controls the electricity of different parts of your building. In this article, we will discuss how to properly chart out your building’s electrical system so as to organize and respond to any complication.
