Eliminating Noise and Vibrations in Air Craft It’s a Balancing Act

    The aircraft industry is an ever growing industry and most likely will not be slowing down anytime soon. From commercial aircraft, fighter aircraft and even private air craft this industry helps to support more than 10,000,000 jobs each and every year, with more than 200,000 general aviation crafts in the U.S. in 2011. These jobs range in depth, knowledge and even security levels, but all those who work in this field understand they are working on things that people use and rely on. Finding problems and remedying them quickly are important, therefore proper knowledge to find the problem is vital.

    Vibrations in aircraft can be a huge nuisance when it comes to aircraft maintenance. The parts that are causing the vibration must be fixed in order to spare the aircraft of further damage. There are a number of reasons for these vibrations, such as bearing vibration, yet some of the most critical can be those dealing with the engine of the aircraft. The engine fan of an aircraft is a powerful took that spends most of it’s time rotating at high speeds. Over time this can and does cause an unbalance in the fan which leads to noise and vibration. This is one reason fan trim balance testing is so important.

    Reasons that a fan becomes off balance it can be due to a number of reasons. Foreign objects entering the fan blade can cause a shift in balance resulting in noise and vibration from the fan. Erosion of the fan blades is also to blame for an uneven balancing act in the aircraft. When the erosion starts to affect one blade but not the others you get an uneven balance and coupled with noise and vibration.

    There are ways to check for vibrations and there is balancing equipment along with portable balancing equipment that can be used to remedy the problem. Fan trim balance testing can be successfully performed with the right tools. Some of the most popular choices include vibration balancing equipment. This equipment is designed to collect data about vibrations especially those vibrations which cause noise or are extremely bothersome.

    Fan trim balance testing is only one of the services provided by the more than 131,000 mechanics and service technicians employed in 2017 in the aviation field. Knowing how to find the problem and correctly solve it is vital, and having the proper equipment is just as important. Never skimp on quality tools and equipment that can help perform the job successfully.
