Within each flight cycle, an aircraft fuel system must deliver clean fuel to the engine at a proper flow rate to sustain flight— regardless of the operating conditions. A fuel system is composed of boost pumps, tanks, strainers, selector valves, pressure gauges, engine-driven pumps, and more.

Typically, there are several tanks to store the required amount of fuel. The location of these depends on the system design and structure of the aircraft. In a standard assembly, a line leads to the selector valve from each one of these tanks, which is operated from the cockpit. The aircraft fuel pump boosts then forces fuel through the selector valve to the main line strainer. The strainer acts as a filtering unit, which removes water and dirt from the fuel. It then travels through a bypass in the engine-driven pump, causing it to rotate. Once it is operating at an adequate speed, it delivers fuel to the metering device to measure, allowing the aircraft to start up. These aircraft fuel systems can be categorized into two variations: a gravity feed system or a pump feed system.

It is not uncommon for aircraft to come equipped with a fuel tank in each wing. In this design, gravity is used to deliver the fuel to the engine; hence, a gravity feed system. The area above the fuel is vented to sustain atmospheric pressure on the fuel as the tank is emptied. The tanks are also vented to each other to maintain equal pressure between the two of them. An outlet on each tank feeds lines that connect to a fuel shutoff valve or multi position selector valve. As the fuel travels it passes through a main system strainer which removes sediment and/or water. It then flows to the carburetor or the primer pump for engine starting and operating. The gravity feed system doesn’t require a fuel pump and is simplistic in design.

Pump feed systems involve one or more pumps that are used to move fuel from the fuel tanks to the engine. Each fuel tank has a line from the outlet to a selector valve. In this system, fuel cannot be drawn from both tanks simultaneously. If the fuel in one tank is depleted, the pump would draw air. This negates the need to connect the tank vent spaces together. The fuel then passes through the selector valve, making its way through the main strainer, where it can then supply the engine primer. It then travels downward to the fuel pumps; one electric pump and one engine-driven fuel pump are arranged next to each other. These draw fuel from the tank and transport it to the carburetor. The two pumps facilitate each other as the engine-driven pump is the primary operator while the electric pump provides a supportive option.

Some high-performance aircraft are equipped with a fuel system that features fuel injection as opposed to a carburetor. This design combines gravity flow with the use of a fuel pump, operating in unison; but we’ll save that for next time.

In order to ensure optimal performance of your drone, it is important to consider battery care. Most drones run off of a rechargeable lithium-ion battery or lithium-polymer battery. There are a few common tips that manufacturers recommend preserving a battery’s power capacity. Take note of the following suggestions to ensure battery efficiency and longevity.

Pay Attention to Your “Low Battery” Alert

                In taking care of your drone battery, you’ll want to make sure to avoid a common mistake— depleting your battery completely. Doing this not only increases the length needed to recharge, but also causes the battery to deteriorate quicker over time and it shortens the flight cycle durations. Most drones have a low battery alert that operates cohesively with smart return, which directs the drone back to its designated home location. It is important to utilize this automatic control or direct your drone to land as soon as the low battery alert is given.

Don’t Overcharge!

                Overcharging a battery can reduce its lifespan and weaken its power capacity, meaning your drone won’t perform with the same power efficiency and you’ll have to replace your battery more frequently. To prevent this, charge your battery 24 hours before your intended flight.

Keep Temperature In Mind

                Drastic temperatures alter the way a battery will charge. Hot and cold temperatures provide challenges. Ideally, you should charge your battery in a cool, dry environment between 60 and 75 ?. A battery achieves its most optimal charging rate between this temperature range.

Remove Your Battery After Flight

                When your drone is not in use, remove the battery. Leaving it attached to your drone depletes the battery faster. As with overcharging, leaving a battery attached to your drone for extended periods reduces the battery’s power capacity.

And there you have it, the 4 key suggestions to keep in mind for drone battery parts & their care. Keep these in mind to preserve your battery and keep it operating at its best. Happy flying!

Aircraft are under a constant state of stress when logging flight hours. Commercial aircraft, for example, have the ability to fly upwards of 14 hours non-stop and their lifetime can extend anywhere from 20 - 27 years in operation. In this time, an aircraft will experience about 35,000 pressurization cycles and will undergo the associated, and often expected, degradation and parts fatigue. So, how do modern aircraft maintain their reliability and safety over time?

Beginning at the production level, an aircraft undergoes FAA regulated inspections and checks to ensure quality control and safety. Manufacturers of commercial airliners usually resort to a non-destructive evaluation (NDE) when an aircraft is on the production line. This program is structured to ensure that components are free of defects before they even see a buyer. Companies that consult these large-scale evaluations include the likes of Boeing and Airbus, among many others.

Maintenance checks are regulated by the FAA and scheduled over the life cycle of an aircraft. Standard parameters set forth by manufacturers by these regulations will include the following: line maintenance, A checks, C checks, and D checks. B checks have actually been absorbed into the A category, as B checks have become obsolete or covered by the A category with the advancement of aviation technology.

Line maintenance of an aircraft often involves up to 12 hours of inspection per week. System checks include some of the elements you may have seen in standard automotive servicing. The assessment will survey the brakes, wheels, fluid levels and landing gear of an aircraft. Any necessary repairs are also attended to during this phase of maintenance.

Proceeding through the life cycle of the aircraft, the next inspection it will encounter is the A-check. These checks are required after every 100 flight hours. Processing of the inspection takes longer than line maintenance, often totaling over 12 hours. Under this careful examination, lubrication and oil are changed, and systems and functional checks should be performed.

Defined as a heavy maintenance check, a C-check is completed between 18 months and 2 years, 1800 flight hours, or 2,000 pressurized cycles. It is typically a 3-week process in which airlines might make changes to interior cabin design or amenities.

Lastly, a D-check is performed after the aircraft has been in service for about 6 years, or after it has received a total of four C-checks. This assessment is broken up into a series of steps, often referred to as C4 or C8 checks. During this inspection, the aircraft is dismantled including the cabin, landing gear, and any applicable accessories. The airframe is then removed, and the engine/s undergo routine maintenance checks.

Despite inspection during and post production, it is crucial to stay up to speed on the durability limits specified by a parts manufacturer. Each aircraft will encounter different levels of pressurization and degradation, and each part’s component will have its own established flight cycle limit. With proper care, following manufacturer and FAA parameters will promote the longevity of the aircraft. 

Despite the millions of dollars it costs to fly and maintain, aircraft have a surprisingly short lifespan with an average of around 30 years. Once the aircraft has to be retired, they go to boneyards— large plots of land where airplanes are parked until further notice. It’s interesting to learn about what happens at the world's largest boneyard— how aircraft life is determined and how retired planes are salvaged for parts.

Retired American planes all end up at boneyards located in California, Arizona, New Mexico, and Texas, where the dry and arid climate is perfect for decelerating rust. So, it makes sense that the world’s largest boneyard is the 209^th Aerospace Maintenance and Regeneration Group (AMARG) in Tucson Arizona. AMARG’s large lot currently holds more than $32 billion of retired airplanes, with a total of 4,400 parked planes.

The operational life an airplane is not determined by years, but by the number of pressurization cycles. It is estimated that an aircraft can make up to 35,000 pressurization cycles, which is around 135,000 to 165,000 flight hours before metal fatigue sets in and the FAA deems it unsafe to fly. In years, it is estimated to be 25 to 30 years depending on the destination and if the aircraft is used for domestic or international flights.

Once an aircraft is retired or decommissioned, it’s stripped and sold for parts. Aircraft parts are huge commodities because while the lifespan of the aircraft as a whole is over, the parts still have a lot of life left in them due to the regular maintenance and repair. Parts are often salvaged and sold for other aircraft still in operation because used parts are cheaper than new ones. Just the scraps of a single aircraft can be sold for up to $55,000.

When preparing for a flight, there are many things to worry about and consider like packing luggage, arriving at the airport on time, fitting the carry-ons in the overhead compartment, and so on. The one thing no one really thinks about and often does automatically, that’s boarding. And no matter if it’s the massive Airbus A380 or the luxurious Embraer Lineage 1000E, when we board a plane, we board on the left side. But most of us can’t even begin to explain why.

Boarding from the left stems from two major reasons: traditional nautical custom and the pilot’s field of view. In nautical tradition ships are docked portside (on the left) because of the tiller, what is controlled by the ship’s wheel and resultingly turns the ship, being starboard (on the right). Many historians believe that planes follow the same marine convention out of habit.

The other reason is that back when planes had to taxi in front of the terminal to discharge passengers, pilots had to be on the left side to more accurately judge the wingspan of the plane and dock in the terminal. As a result, it was easier to have passengers embark and disembark on the left and have all the servicing of the plane done on the right.

Servicing a plane can involve anything from unloading and loading cargo, restocking the food carts, refueling, or hooking up the plane to the auxiliary power unit. With how complex planes are and how many different tools and aviation parts can be required to service them, servicing on the right and away from passengers is safer too.

The efficiency of a gas turbine cycle rises as the turbine entry temperature is increased. Because of this, the hotter the combustion gases that go in to the first turbine stage, the more particular power the jet engine can create. In a modern engine, about twenty percent of compressed air bleeds off for cooling and sealing purposes. This is mostly for guide vanes and turbine blades. The stators and the outer wall of a turbine’s flow passage utilize cooling air moving from the compressor between the combustor and casing of the outer engine.

The turbine rotor blades, disks, and inner walls of a turbine flow passage uses the air that bleeds from the compressor though inner passageways. Because the stators materialize before the first row of rotating blades, it is expected that the first stage of stators are uncovered to very high temperatures. This includes local hot-spots from the combustor close by. The temperature at this first stage is slightly lowered by dilution of the gases with cooling air, along with the relative velocity effecting and powering extraction from the turbine.

The laws of thermodynamics demand that because of combustion inefficiencies, there be a pressure loss inside the combustor. This means that the mainstream pressure at the first row of stators in the turbine located after the combustor is lower than on the way out of the last stage of the compressor. This difference in pressure is used to guide the cooling air through the internal passageways and into the stators and blades.

Earlier in the year, The Boeing Company finished up the flight tests for the newest model of the KC-46 Pegasus wide-body, a plane used to re-fuel other squad member’s during flight. Now they are waiting on word from the FAA to see if their new tankers can fly legally. More certifications are needed on this aircraft than normal because it is classified as a tanker, meaning it may take longer for the tanker to become airworthy.

This new model is based off a classic Boeing 767 with some modifications to allow for refueling multiple planes. The tanker can also be re-fueled itself by other planes, which required a few tweaks to the previous model. The new tanker model is being built in Boeings private Everett location, just north of Seattle, Washington, and testing is taking place in Seattle proper.

The draw of building a new tanker, like the KC-46A, is the fact that it’s a multitasking dream. Not only can it re-fuel other planes in its squadron but it can also handle a load of cargo, quite a few passengers, and if needed, individuals who need medical attention.

The KC-46 has successful flown with seven different types of aircrafts and logged over 2,000 miles in flight. Even though the delivery, and implementation, of the KC-46 line is still some ways out, the fact that they successfully passed flight tests means its one huge step closer to being air worthy.
