All airplanes have engines. Whether it&#8217;s a turbofan or turboprop, they are the main thrust-generating devices. Engines produce the forward force needed to overcome drag and move the airplane through the air. While most people are familiar with engines, however, pylons often go unnoticed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Basics of Engine Pylons<\/h2>\n\n\n\n<p>Engine pylons are structural assemblies that connect aircraft engines to fuselages or wings. Most aircraft engines aren&#8217;t simply bolted or fastened to the airplane. Instead, they are connected via pylons.<\/p>\n\n\n\n<p>Aircraft engines are housed in containers. Known as nacelles, they contain many essential components while also providing a more aerodynamic and streamlined shape. Engine pylons are designed to connect nacelles &#8212; along with the engine and related components &#8212; to the airplane itself.<\/p>\n\n\n\n<p><strong>Engine pylons are available in different materials, some of which include the following:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Aluminum alloy<\/li>\n\n\n\n<li>Titanium<\/li>\n\n\n\n<li>Stainless steel<\/li>\n\n\n\n<li>Carbon-fiber composite<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Where Are Engine Pylons Located?<\/h2>\n\n\n\n<p>On most commercial airplanes, engine pylons are located directly beneath the wings. They extend downward from the engines where they connect to the top of the nacelle.<\/p>\n\n\n\n<p>Other types of airplanes may use different placements for engine pylons. Smaller airplanes, such as regional jets, often feature rear-mounted engines. Airplanes such as these feature engine pylons near the back of the fuselage rather than under the wings.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Importance of Engine Pylons<\/h2>\n\n\n\n<p>They may seem like basic support brackets, but engine pylons serve several key purposes. For starters, they transfer the weight of the engine to the airplane&#8217;s primary structure. Engines, of course, are quite heavy. Small piston-driven engines may weigh just 400 pounds, whereas larger jet engines can weigh over 20,000 pounds. Pylons transfer this weight to the airplane&#8217;s main body, allowing for a safe and stable flight.<\/p>\n\n\n\n<p>Engine pylons also provide a pathway for critical systems. Engines typically have fuel lines, wiring, hydraulic lines and other control systems. These systems must connect to the airplane itself. Pylons provide a pathway so that critical systems such as these can run from the engine to the airplane.<\/p>\n\n\n\n<p>Fire safety is another reason airplanes have engine pylons. Engines, particularly jet engines, produce intense heat. During combustion, the internal temperature of a jet engine can reach 3,000 degrees Fahrenheit. Engine pylons are often designed with fire-resistant barriers and thermal shielding to prevent fires from spreading to the airplane.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Engine pylons play an important role in aviation.
