For those operating in aerospace and automotive settings, the Federal Supply Classification system upheld by the United States Defense Logistics Agency (DLA) often proves to be an essential tool for streamlining procurement processes for many important items. Federal Supply Classes (FSC) play a major role in this, serving to organize similar supplies together in a simplified structure for quick identification, management, and trade. In this blog, we will provide a brief introduction to FSC 2950, a class which contains turbosuperchargers and their related components.
Turbosuperchargers, often referred to simply as “turbos,” are forced induction systems that serve to increase the power output of internal combustion engines. They achieve this by compressing intake air and forcing an increased volume into engine cylinders. This results in a more powerful combustion stroke, increasing the overall amount of energy produced. Turbosuperchargers are most commonly found on aircraft, automobiles, and other vehicles that prioritize high performance, fuel efficiency, and altitude compensation.
Compressor wheels are responsible for drawing in air and raising its pressure for optimal combustion. They do this by rapidly rotating, their design causing a large volume of air to be directed into the engine’s intake manifold.
The turbine wheel of a a turbosupercharger is driven by exhaust gasses during the combustion process, allowing for kinetic energy to be harnessed to drive the compressor via a shaft.
The housing of the assembly serves to enclose the compressor and turbine wheels, directing the flow of air and exhaust gasses throughout the system. The housing also provides structural support for the turbocharger.
Turbosupercharger regulators control the boost pressure of the turbocharger, ensuring that the engine receives the amount of power necessary for optimal performance.
Bearings support the rotating shaft of a turbocharger, specifically being designed to withstand the high speeds and temperatures typical of operations. Proper lubrication of bearings is essential for their longevity.
Seals prevent oil from leaking from a turbocharger, necessary for preventing unnecessary or wasteful oil consumption.
Actuators control the operation of a turbocharger's wastegate or variable geometry turbine, allowing for careful management of boost pressure.
Intercoolers cool compressed air before it enters the engine, heightening its density to further bolster system efficiency.
There are a number of turbosupercharger options that provide distinct characteristics and applications, making it important that one takes the time to find the best fit for their particular needs. For our purposes, we will cover the most basic types that are available, including single-turbo systems, twin-turbo systems, and variable geometry turbochargers.
Single-turbo systems use one turbocharger to boost an engine, being relatively simple and cost effective. As the most common type of system, one will find such assemblies on many vehicles looking to bolster performance.
Twin-turbo systems use two turbochargers to boost efficiency, providing many vehicles improved performance and responsiveness. Twin-turbo systems are often used in high-performance applications, a result of their higher capabilities.
Variable geometry turbochargers use adjustable vanes to control the flow of exhaust gases to the turbine wheel, facilitating optimized performance across a wide range of engine speeds. While being complex and more expensive than other options, these systems offer the most potential benefits.
