How do Exhaust Systems Impact Your Aircraft Engine?
Having an exhaust system that is both well maintained and serviced will ensure that an aircraft is able to perform with great efficiency and power, as well as allow for safe operation. The aircraft exhaust system plays two vital roles: venting spent gases and heat from the engine, as well as providing heat for the cabin and carburetor. In this article, we will discuss the role of the exhaust system for engines and the aircraft as a whole.
Aircraft engines perform better the higher the engine pressure ratio is. The engine pressure ratio refers to the ratio of the propelling nozzle’s total pressure upon exit divided by the pressure at the compressor entry. Exhaust plays a factor in this ratio as exhaust can act as an obstruction, thus decreasing the performance and efficiency of the aircraft. Aircraft are constantly exposed to very intense heat during their operation and fuel combustion, thus it is very important that the exhaust system performs optimally to disperse built up gases and heat.
During the course of an exhaust system’s operating life, there is risk of deterioration, blockage, and residue deposits that can build up over time. During inspection and maintenance, these risks should always be checked for and cleared as to ensure efficient and safe operation of exhaust systems. Ensuring proper installation and alignment of every system component also goes a long way for performance.
Tuning an exhaust system is something that can also benefit the exhaust and engine’s performance for piston driven engines. The exhaust tubing length can be manufactured to specific lengths, and exhaust gases can be directed through these towards mufflers. Within the exhaust muffler housing, gases are diffused into absorption materials so that they may be quieted. Tuned exhaust systems allow for more efficient venting, thus also benefiting the entire system as a whole.
