Maintenance, repair, and overhaul (MRO) describes the maintenance activities conducted regarding aircraft and aviation. Often, MRO are professional services provided by a variety of businesses and experts, working with different segments of aviation including business and commercial aircraft, helicopters, military, and more. For aircraft in general, there are various set FAA guidelines for required inspection, repair, and overhaul to ensure that aircraft remain airworthy and safe to operate. MRO is an important service to ensure aircraft remain airworthy, and these providers play a very integral role in supply chain management.
National Stock Numbers (NSNs) are assigned by the U.S. Defense Logistics Agency, which is a sub-branch of the U.S. Department of Defense. All items that are stocked, sourced, and procured within the U.S federal supply system is assigned an NSN by the DLA. A manufacturer can not request an NSN. Instead, there must be an official need for the component from either the U.S. military itself, a government contractor, or a NATO country. Also known as NATO number, NSNs are officially recognized by all the NATO countries. Although a U.S. based program, components manufactured outside the U.S. are eligible for NSNs.
Derived from the term “thermally sensitive resistor,” thermistors are accurate and cost-effective sensors for measuring temperatures. Thermistors are available as negative temperature coefficient (NTC), and positive temperature coefficient (PTC), with NTC thermistors being the more commonly-used. NTC thermistors have their resistance decrease as their temperature increases, while PTC thermistors’ resistance increases as their temperature increases.
What goes up must inevitably come back down. An aircraft’s landing gear ensures that the “coming back down” part ends safely and allows the aircraft to maneuver safely on the ground. Landing gear on aircraft comes in several different types and configurations, which this blog will explore.
The increasing complexity of aircraft engine systems has facilitated more requirements of proper lubrication. Aircraft engines require lubrication to prevent friction from reducing the engines’ efficiency; oil is the lifeblood of the engine. If the oil flow to the bearings stops, the lubricating films break down and cause degradation, wear and tear, and burning between moving parts. Fortunately, the engine fuel pump and oil system are very reliable. Like the circulatory system of the human body, they quietly perform their functions.
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.
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.
Aircraft are under a constant state of stress when logging flight hours. Boeing 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?
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.
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.
