Airplanes are exposed to extreme stress during flight, including lift, drag, weight and thrust. Lift is an upward force generated by an airplane’s lifting surface. Drag is air resistance that counters an airplane’s forward motion. Weight is the gravitational pull … Continue reading →
Split winglets have become increasingly common. Also known as split scimitar winglets, they are found on many 737 airliners, including the 737 MAX 8, 737 MAX 9, 737 MAX 10, 737-800 and 737-900ER. Like all winglets, split winglets consist of … Continue reading →
When most people think of hex nuts, they envision a six-sided fastener with internal threading. After all, the term hex refers to objects with six sides, so conventional wisdom may lead you to believe that all hex nuts have six … Continue reading →
It’s a common misconception that airplanes have isolated fuel tanks — similar to those found in automobiles. With the exception of certain all-electric models, most airplanes store fuel. They burn this fuel with air to power their respective engines and … Continue reading →
Lighting is an important part of all modern airplanes. A typical airplane has anywhere from hundreds to thousands or even tens of thousands of individual bulbs. Some of them large, such as external navigation lights and anti-collision lights. Miniature and … Continue reading →
Propeller-driven airplanes remain a staple of the aviation industry. While most airplanes used for long-haul flights are powered by turbofans, propeller-driven airplanes still account for about two-thirds of all flights globally. Propeller-driven airplanes include those powered by piston and turboprop … Continue reading →
Circuit breakers are found in nearly all modern airplanes. Not to be confused with fuses, they protect electrical equipment from overcurrent-related damage. If the current flowing through a circuit exceeds a safe amount, the circuit breaker will disrupt it. Current … Continue reading →
Ever wonder if airplanes use tube or tubeless tires? With the exception of specialized aircraft like seaplanes, most airplanes have tires. Small airplanes may have just three tires, whereas jumbo-sized airliners can have up to 23 tires. Tires, of course, … Continue reading →
Nutplates offer a simple and effective solution for blind fastener installations. Also known as plate nuts or anchor nuts, they feature a threaded nut with an anchor base. Even if you can’t access the rear side of an assembly, you … Continue reading →
