How do Electromechanical Relays Work

How do Electromechanical Relays Work?

To put it simply, an electromechanical relay is essentially just a switch. However, relays are controlled by electromagnets, whereas switches are manually actuated. They are used in a control circuit when a low power signal is required, or when several circuits need to be controlled. Inside the relay, a small current is used to create a magnetic field within the coil. This magnetic field is used to switch or control a much larger current. Relays come in a variety of sizes and can use different technology, but they operate with the same basic concept that makes them an electromagnetic relay.

It should be noted that like many other circuit diagram symbols, the symbols for relays can vary quite a bit. The most common way to see a relay symbol shows the relay coil as a box with protruding contacts shown as open or closed. Older circuit diagrams might show the replay as an actual coil. Regardless, it is a good idea when working with relays to know how they may or may not appear.

Although solid state switches are currently more popular due to their higher efficacy, relays are still ideal for many applications due to their unique properties. When a current flows through the coil box an electromagnetic field is created, pushing contact ends together, completing a full circuit. Relays have several advantages and disadvantages just as any other type of technology. On one hand, relays provide physical isolation between circuits and can withstand extremely high voltages. On the other, they are slower than semiconductor switches and have a limited lifetime.

Where are Electromechanical Relays Used?

Relay switches can be used in automotive applications, industrial applications, aerospace applications, large power operations, etc. Each relay is specific to the application in which it is to be applied and there are many to choose from on the market. So, it is important to weigh out the pros and cons when selecting any type of electronic component.

Basics of a Turbine Engine

Also known as a “gas turbine” or a “combustion turbine”, the turbine engine is a type of internal combustion engine categorized by its use of a special type of oxidizer mixed with fuel and combusted in a carefully designed combustion chamber. Turbine engines convert energy into a type of mechanical-based motion to power aircraft, trains, ships, electrical generators, pumps, gas compressors, and tanks.

There are three main components of a turbine engine: the upstream rotating gas compressor, the downstream turbine, and the combustion chamber. Energy is created and added a stream of gas in the combustion chamber. Air and fuel mix and then ignited, increasing the pressure, which in turn causes the fuel to experience higher levels of combustion and an overall increase in temperature. Then, the mixture is sent to the turbine where the gas flow starts to move in high volumes and at a very fast rate. Afterward, it moves to a specially designed nozzle that emits the fluid mixture over the blades on the engine which spin and power the compressor. Eventually, the emitted pressure and overall temperature dissipate.

Compared to standard engines that use pistons, turbine engines are significantly simpler in operation but are more powerful in energy output. Turbine engines are considered simpler than standard engines because out of all the parts, there is only one main component that is considered a moving part. On the other hand, piston engines have dozens of individually moving parts. Turbine engines are also more optimal than standard engines. They’re designed to run optimally in lower pressures and higher altitudes, operate at higher velocities, have better internal lubrication, and support more weight while still providing more power than standard engines. As a result, turbine engines are considered the more popular and optimal choice amount manufacturers in many industries.

Types of Aircraft Bearings

The pyramids of ancient Egypt, barstools, gearsets in car transmissions, and the earthquake-proof San Francisco International Airport all have one unlikely thing in common: bearings. While relatively simple to understand, the difference that using a bearing makes can be massive. And the reason is simple: according to basic physics, things that roll meet less frictional resistance than things that slide. Aptly named, bearings “bear” the load by using smooth metal for the balls or rollers, and the inner and outer surfaces they roll against to minimize the contact area and allow for less friction and smoother movement.

There are many different types of bearings which can be classified into three categories defined by their type of loading: radial, thrust, or a combination of both. While radial loads act at the right angles of the shaft, thrust loads act parallel to the axis of rotation. Radial loads require bearings such as roller bearings which use cylinders to hold heavy loads, or their thinner counterparts, the needle bearing. On the other hand, thrust loads can be handled with roller thrust bearings or ball thrust bearings which are commonly found in gearsets and barstools respectively. And finally, combination loads can use ball bearings for smaller loads and tapered roller bearings for larger loads like car hubs require.

Of course, beyond the examples already listed, many other technologies require bearings of all kinds to function, notably aviation technology. From the common ball bearing to the slightly less common tapered bearing and needle bearing, aviation technology has its uses for bearings of all sorts. With the diverse options in bearings on the market today, finding the right bearing to suit your aviation needs may seem daunting.

Piston Engine Aircraft vs turboprop

Piston engine, or reciprocating engines, are related to the steam engine, which was first introduced in the early 17th century. In simpler terms, a steam engine utilizes heat to create stream pressure, which is then used to generate a rotating motion. After its creation, steam engines were used to drive everything ranging from mechanical equipment to railway trains. Today in aircraft piston engines, gas propulsion is used instead of steam to create pressure inside the engine.

Piston engines are distinguished by at least one cylinder, with each cylinder holding a tight-fitting piston (known as a solid cylinder). This fitting piston can be moved back and forth freely inside the cylinder. Each piston is attached to a crankshaft by a connecting rod. When fuel is established and set off inside a cylinder, the hot gas created expands with great force, which drives the corresponding piston forward inside the cylinder. This in turn moves the connecting rod forwards as well, causing the crankshaft to turn. The full turning of the crankshaft moves the piston back into the cylinder and the cycle begins again.

Turboprop aircraft are fueled by a turbine, which is an easier term for a “fan.” A turbine is a rotary driven fan that gains energy from either fluid flow or airflow. A simple turbine design incorporates a rotor, or rotating wheel, with the angled blades attached. As fluid or air navigates through the blades, the fluid or air pressure against the blades will make the rotor spin. In an aircraft turbine engine, the high-pressure gas, which results from the combustion of jet fuel, takes the place of water or wind to steer the motion of the rotor. Because of this, aircraft turbine engines are usually seen as gas turbine engines.

Vishay PIN Photodiode

Vishay Intertechnology recently introduced a new high-speed silicon PIN photodiode with an added feature of enhanced light sensitivity. A photodiode is a semiconductor diode that converts light into an electrical voltage. When energy fueled photons are absorbed by the detector, a formation on charge carriers is created; this formation is then separated in the space-charge region, resulting in a photocurrent.

Vishay’s PIN photodiode, the VEMD8080, has numerous features which set it apart from the competition:

  • 4.8mm by 2.5mm top view; radiant-sensitive area of 4.5mm²
  • Surface-mount package with a low 0.48mm profile
  • Fast switching times
  • Low capacitance of 47pF –resulting in precise signal detection
  • Wafer technology – detects visible and near infrared radiation over a spectrum range of 350nm to 1100nm
  • 30% improvement for green LEDs –allows for optical heart rate detection in wearable devices (fitness trackers, smart watches, etc.)
  • 65° angle of half-sensitivity
  • Temperature range of -40°C to 85°C
  • 950 nm wavelength of peak sensitivity
  • Moisture sensitivity level of 4
  • Floor life of 72 hours

The VEMD8080’s unique size and shape allow for light emitting diodes to be placed closer to the radiant sensitive surface area, resulting in maximized signal strength. When used with green LEDs, the device’s shape grants the light-emitting diodes the ability to maximize their signal strength, making them operate quicker and more efficiently.

PIN photodiodes are the most commonly used form of diodes. Typically, they can be found in audio CD players, DVD drives, and optical communication systems; these parts can also be used as nuclear radiation detectors.

Bombardier Aircraft Parts

Bombardier has finally reached their seven-year goal in completing their state of art reclining chair, known as the Nuage passenger seat. After constant trial and error, the Aerospace company, has found a solution to not only correct posture but make the flight more worthwhile. The chair is scheduled to be placed upon the Global 7000 once it has been certified.

Studying ergonomics was one of the company’s main tools upon development of the Nauge to be able to key point the troubled areas that standard seats affect. This new state of the art technique used is one that is described by Bombardier as “furniture engineering.”

The experts can attest that standard aircraft seats do not let the body rest as the body is still forced to hold its self-up right.

The Nauge Seat has been able to create a solution to be address this issue by,

“dipping the pan down while the seat back reclines, the cushions can cradle the critical portion of the passenger’s body, allowing the muscles to relax more fully.”

Not only are have there been configured options created for reclining but options for adjusting the head rest manually as well. Passengers are now able to adjust the head rest to be able to experience a more comforting experience for their head-neck junction.

Along with many new innovative features that the chair offers, its ability is lower, or raise has been added to be able to allow passengers of most heights to comfortability reach the floor. A Unique characteristic that the Nauge seat offers to make sure it keeps its center of gravity is the “floating base “as it has removed the standard rails that seats are usually mounted upon. All of the chairs state of the art equipment can be controlled through the chairs armrest, making it user friendly for everyone to enjoy!

Plane Parts 360 is a major bombardier aircraft parts, aircraft seats parts, and bombardier parts supplier in the industry. Providing you with some of the hardest to find parts that have been deemed obsolete. Parts 360 can offer extensive traceability to parts required to show full traceability of parts.

Safran Arriel 2H Engine

EASAs certification regulations have been recently meet by Safran Helicopter Group to be able to bring their Arriel 2H Engine to life. Currently Safran has plans of having their engine to be able to be incorporated into a AC312E, a civilian helicopter, manufactured by Avicopter. This particular specification of the Arriel was chosen in the year 2015 due to its efficiency and unique characteristics created by Avic Harbin Aircraft Industry Group. The 2H engine derived from the previous model known as the 2+. With the new models enhanced technology, the 2H has the power to takeoff at a rate of 986 shp.

The AC312E aircraft has a narrow design which enables it to be more efficient and aero dynamic. Its composition makes the helicopter a light medium twin derived that has taken the characteristics of former aircrafts such as the “A” model. Much the AC312E was based on other models that are descendants of the “A” models such as Airbus AS365 which have been given full authorization to be procured in China.

“ The 312E will be able to carry nine passengers, have a maximum cruise speed of 165 knots, a maximum takeoff weight of 9,921 pounds, and a service ceiling of 19,685 feet.”

The procurement of these type of aircrafts began in the early 1980s and completed by the 1990s to be placed into the full service. Later on, by the year 2002, the company created a more enhanced version of the Arriel 2C engine. The AC312E has completed their first flight in 2016 but has yet to obtain their EASA certification which is scheduled for late 2018.

The 312E capabilities are a great contribution to the aircraft as they offer extensive traits such as electronic flight bags, helicopter taws, RTA-4112 MultiScan weather radar, synthetic vision, and a state of the art TTR-4100 TCAS traffic surveillance system.

Plane Parts 360 has been a quality supplier for Safran helicopter engine, Airbus helicopter, and Airbus helicopters AS365 parts.
