Among the various types of aircraft landing gear, all are currently sorted into two main categories: fixed and retractable. Fixed landing gear simply refers to gear that is permanently attached to the airframe. Retractable landing gear refers to a system that allows landing gear to be extended and retracted from the aircraft as needed. The use of both arrangements primarily relies on aircraft speed and internal volume.
If you regularly fly on commercial airlines, you are likely familiar with retractable landing gear to some degree. This configuration is the most commonly used setup on standard commercial aircraft. Large aircraft retraction systems customarily rely on hydraulics for operation. A landing gear parts supplier, and/or a landing gear parts distributor, can expect to encounter conventional hydraulic systems components. These include, but are not limited to priority valves, actuating cylinders, and selector valves. Another vital part in the retractable gear layout is the gear door. Gear door operations and arrangements vary by aircraft. Most arrangements retract the landing gear into the fuselage, if there is space. This is typical in aircraft such as the Boeing 747 and Airbus A340. If space is not available, extra space is built extending from the fuselage.
Though the retractable configuration is the most common among commercial aircraft, fixed landing gear is still in production. It is most frequently seen on relatively small, light-weight, single engine aircraft. On occasion, it is also seen in light-weight twin engine planes. In a fixed arrangement, the landing gear parts are attached to the airframe, which exposes it to the slipstream in flight. This creates what is referred to as parasite drag. This occurs due to the extension of the landing mechanics outside of the airframe. As long as the aircraft is relatively slow, it will benefit more from having a fixed landing gear system. This is due to the fact that retractable landing parts are quite heavy. Induced drag is drag created simply due to the added weight of retractable landing gear parts. Overall, in order for fixed landing gear to be more beneficial to an aircraft, the potential parasite drag must amount to less than the potential induced drag of retractable mechanisms.
Landing gear arrangements have changed drastically over time. Leonardo Da Vinci is believed to be one of the first conceptualize a formal landing gear system for his “flying machines”. Fast forward to the 1920’s, fixed landing gear was positioned, statically, under the fuselage. It was not until 1927, that research found a considerable amount of fuselage drag was contributed by fixed landing gear. Aircraft enthusiasts might also be familiar with the 1930’s Boeing Monomail, which is one of the first planes credited with the initiation of retractable landing gear. Nearing a century after the birth of commercialized retractable landing gear, both fixed and retractable forms are still in use.

An aircraft actuator is a type of motor that moves mechanisms and systems using hydraulic fluids and currents. They produce linear, rotary, or oscillatory motions. Actuators have applications in many fields and can be used in many kinds of machinery. Many of our common household items, such as printers and disk drives, have actuators. They can even be found in cars! But, because they have so many uses, and each is subject to its own specific conditions, there are considerations to be had when deciding on which actuator to use. The four main types are:
Hydraulic actuators require a cylinder which applies hydraulic power to start the mechanical routine. It takes more time to gain speed and slow down because liquids are incompressible. The hydraulic actuator can also be operated manually, like a hydraulic car jack .
Pneumatic actuators are very similar; however, they use compressed gas instead of liquid. The compressed gas is moved into a linear or circular motion, depending on the type. The pneumatic actuator is used more in main engine controls because it exhibits a quicker start and stop from the source. It is also used in projects where cleanliness is a priority, because unlike the hydraulic actuator the gas will no spew liquids or spill. However, this type of actuator is generally larger and louder.
Electric actuators convert electricity into torque. This actuator is used to create motion for machines that require multiple valves, such as gate or globe valves. Electric actuators are often installed into engines, where the actuators open and close the valves. This is also another relatively clean option because it does not require any fluids.
Mechanical actuators convert the circular motion into linear motion. This type of actuator is commonly used in larger sized machines. Devices like rails and pulleys are used in order to convert the motion.

For first-time flyers, there’s nothing more terrifying than the little shudder and deceleration you feel right before the pilot comes on the PA system and announces that they’ve shut down the aircraft engine. Passengers will suddenly remember the headlines they’ve seen over the years: the 2010 Qantas flight 32 which had catastrophic engine failure four minutes after takeoff from Singapore, or the 2009 US Airways Flight 1549 incident where the pilot had to land in the Hudson River after losing both engines to bird strikes, to name a few.
Fortunately, while losing an engine sounds scary, there’s no reason to panic. Engine failure is so rare, when it does happen, it’s immediately turned into sensationalized headlines in every media outlet. Engines may shut down during flight for any number of reasons, ranging from the ingestion of material, like hail or a bird, to a system malfunction. Most of the time, passengers won’t even notice the difference.
Jet airliners are always equipped with at least two incredibly powerful engines. In the US, it’s mandated by the Federal Aviation Administration (FAA) that jet airliners be able to safely operate with only one engine, even through takeoff. Of course, with one engine down, the airliner’s range is significantly reduced and will usually divert to the nearest airport, but it can still fly. In fact, even with total engine failure, it’s not likely that the plane will just drop out of the sky.
In the case of total engine failure, the movement of air over and under the aerospace wings is enough to allow the airplane to glide. And that’s exactly what happened with US Airways Flight 1549. That’s also what happened in the 2001 Air Transat Flight 236, when the airplane lost all engines due to improper maintenance; they still managed to travel nearly 20 minutes without power and land safely without casualties in the Azores.
Flying can be scary, but it shouldn’t be. It’s a common and popular form of travel because it’s so safe that it’s statistically got a lower risk than driving a car does. But, at ASAP Distribution, owned and operated by ASAP Semiconductor, we know it’s important to have peace of mind. So, as a premier aviation and aerospace parts distributor, we make sure to always stock the highest quality parts, new and obsolete for all your mission-critical and AOG requirements.

As you wait in the airport terminal for your turn to board, you’ve probably looked out those large windows, watching the planes and air traffic personnel as they go about their routines. You’ve probably noticed that no matter what direction the flight is supposed to go, it seems like all the planes are taking off in the same direction. But have you wondered why?
To understand why planes takeoff and land in a certain direction, we must first understand the basics of flight. If you draw a basic free-body diagram of a plane in flight, you’d draw four vectors: thrust, drag, lift, and weight. Thrust is the forward force generated by the aircraft engines and accelerates the plane forward. Drag is the backwards force of air that slows the plane. Lift is the upward force generated when air passes over and under the wings at a high rate. And weight is the gravitational force pulling the plane down. Planes can only fly when thrust is greater than drag and lift and weight are equal.
Once the plane reaches significant speeds and gets enough airflow over and under the aircraft wings, the pilot pulls back on the controls, and the plane takes off. While the plane can takeoff in the same direction as the wind, pilots normally takeoff in the opposite direction and redirect when they’re airborne. Going in the opposite direction of the windflow helps the aircraft get additional lift, which allows the takeoff distance to get shorter and faster, which saves on fuel.
Landing also benefits from opposing windflow. Windflow in the opposite direction of the plane adds to the drag force. This allows the plane to have a lower approach speed, which means braking is easier. Windflow in the same direction of the plane adds to the thrust, meaning that the plane has to approach the runway at a higher speed, which requires a longer runway to allow for safer braking. Not all airports have that luxury. So, when they can, air traffic control and pilots will always coordinate to change the direction of landing and takeoff in order to go opposite the windflow.

Starting a jet engine is a complicated process that takes some vital actions to complete. The main and most important part is to make sure that the engine has sufficient airflow, this is so that the engine can compress the air to successfully cause the chemical reaction with fuel to provide thrust.
Jet engines have several sizes, the auxiliary power unit is a smaller sized engine that generate very high thirst power and functions independently from the other engines. They are usually used in support of larger engines and take fuel from the same tank as the larger main engines. However, since the auxiliary power units are smaller in size, they usually start with a battery and not with fuel. These smaller jet engines take electrical power from either a battery or external power unit generating enough power to turn the engine blades to start the engine and provide thrust to move jet aircraft.
The jet fuel starter is generating energy through fuel but functions directly with the engine to help start it and jump start the process of starting the jet engine. Now that the jet starter provided the energy to start the engine, we can use the method of Cross-Bleed Start which uses the air from another already started engine to generate enough airflow to start itself. However, all of these ways to start a jet engine take precious resources and cause wear and tear on the plane, in this case to avoid this you can start an aircraft jet engine by Air Start Unit. This vehicle is separate from the aircraft itself is a unit that starts the engine and provides alternative options that the aircraft itself.
With the awesome ability of jet engines, and the many ways to start them, they provide flexibility on how you want to start up your jet powered aircraft. For all of your aircraft distribution needs, ASAP Distribution provides the easiest and most efficient way for you to get the aircraft parts you need, ASAP is the primer supplier of aviation parts around the world and with our streamlined website you can get the parts you need and be confident you have the most advanced, efficient, and modern way to fly for a exceptional price.

As fuel prices continue to lower companies across the globe are seeing airlines, as well as private owners, sinking their money into taking care of their planes and using them for long stretches of time. This shift means that facilities who repair and maintain aircraft engines are seeing companies ask for older models for their aging planes. This change means that companies are scrambling to find older engine models, meaning that the market has quickly gone from being flooded with aviation parts to almost completely barren.
When you investigate why this change may be, you start to notice the influx of money that many companies are experiencing right now. Organizations that used to be floundering are now making back the money they sink into their planes because fuel prices have started to regulate themselves. It is now not uncommon to find fuel for less than $100 dollars a barrel, something that used to be a pipe dream. This change in fuel prices allows people to hold onto aircraft for longer, resulting in MRO facilities, being bombarded with work orders for older engine models. Something that can help almost everyone, across the board.
Even though the market is no longer saturated with products, MRO’s and Engine Dealers, are finding new life in outdated and unwanted parts. Many aerospace companies have stated that they can easily strip older, unpopular engine models to sell off for parts that can be used on planes and engines that are currently having a moment on the market.
What we don’t know though, is how long this surge will last? Even if this trend dies down in the next month or so we can still look back and see the impact one small change, fuel prices, in the market can make on the entirety of the aircraft industry.

Often many people believe that creating your own computer is mere rocket science due to the complexity of the technical vocabulary. Once understanding the basics of the vocabulary, it is best believed that creating the entire computer from scratch will no longer seem that impossible.
Keywords that should be known before completing such tasks are Case, Cooling, Motherboard, CPU, GPU, Power Supply, RAM, Storage and so on.
Starting with the Case and how it will be the shell to your entire project. The size should be determined on the entire set up you wish to create. Bigger cases come equipped with more slots/entries located on the back. Three popular variations are the towers are full tower, mini tower, mid tower.
The Cooling for the CPU is essential to be able to keep your system at temperature running smoothly. According to Extreme tech.com they state that,” Most enthusiasts opt for more prosaic air cooling methods.” The size of the cooler can sometimes layover of the ram slots but is not a major concern.
Motherboards are the brain of the operation and have different potential and capacities in each one. There are three general motherboard types known as the Mini-ITX, Micro-ATX ( maTX), and the ATX being the most popular.
The CPU goes hand in hand with the motherboard and a combination of both is what determines your RAM capability.
Along with hardware to help run the entire system, there is such thing known as the GPU (Graphics processing unit.) This CPU can live without it but is meant for the creation of an image on a display (output).
To bring the energy to the CPU is requires a well-rounded SPU (supply power unit) to be able to distribute the power equally to every component. Extremely recommended to never buy a generic PSU to avoid complications with no name power supplies.
Lastly, Storage is what holds and transmitters all the files saved to your computer. Rule of thumb for Storage units, the larger the storage the slower hard drives and vise versa.

The 630 V connectors for small servo motors which includes full connectivity power, signal, and data is the newest and best connector in the game. This connector was created by TE Connectivity. The M12 Motor Connector is little, yet extremely sturdy, and is used as a single-cable installation solution that covers the transmission.
Most would think that as things become bigger, so do the regulations, but in the case of the motor applications the regulations are growing, but the units are becoming smaller. Due to this high demand for small units with fast assembly and advanced abilities, TE has been the first throughout the world to create a fastener of this class. On top of that, the fastener is angled to create a very flexible design for all needs.
They included a rapid locking system, flexible mounting, extreme protection against water and dust that may damage others over time. To ensure this protection, TE uses a nickel-plated metal cover that has 360-degree connection abilities. There is also advanced protection against flames, the highest in the industry. Customers are not forced to purchase the 360-degree fixed ground connector, there is also a free mounting version with all different forms and designs to fit all needs.
They are not stopping with the variety they have now, TE is continuing its advancement and wide array of abilities and designs. M12 Motor Connectors are not specific to one industry, but rather are used in most industries, which is why TE is so focused on expanding its abilities. Some of the popular industries with the need to the M12 Motor Connectors are robotics, construction, machinery, transportation, agricultural, and even the food and beverage industry.

Engines are made up of many accessories that highly contribute to the safety of the engine, and therefore the safety of the plane and its’ passengers. When an aircraft has an issue, it is not automatically the entire engine that needs replacing, but most likely one of its’ accessories. When the accessory is the only issue, that is good news, it is obviously a lot cheaper than replacing a whole engine.
The starter is exactly as it sounds, its assists to start the engine. Alternators are considered one of the highest failing items in an aircraft since they were originally manufactured for automobiles. Its purpose is to convert mechanical energy to electrical energy. Oil huge when it comes to a smooth-running engine. It circulated within the hot engine keeping everything lubricated, which in turn heats up the oil rapidly. That is where the oil coolers come into play, these coolers prevent the engine from over-heating. Ignition systems are what burn the fuel, and most aircrafts are built with two ignition systems, along with two spark plugs.
The spark plugs ignite the fuel prior to it entering the ignition system. There are two of both the spark plugs and ignition systems in case one fails, the other one can do all the work needed for a safe landing. Fuel systems, also called fuel tanks, are where the fuel enters and is stored prior to being sent to the engine by the fuel pump. Hoses allow for connection of different components and liquids, and provide a safer engine all together.
The last accessory that pulls the aircraft engine together is the exhaust systems, this is where all the fuel and engine exhaust is released to prevent overheating or damage to the engine. These accessories can be hard to keep track of, and hard to find. Which is where a reputable aircraft engine parts supplier can be a huge commodity.
