Aircraft exhaust systems have three main functions: venting the burned combustion gases overboard, providing heat for the cabin, and defrosting the windscreen.
To understand how an exhaust system vents burned combustion gases overboard, we must first understand the combustion process.
In a nutshell, jet engines work by burning fuel in air to release hot exhaust gas. To begin, a fan at the front of the engine sucks the cold air into the engine through an inlet. Compressed air is mixed with fuel in the combustion chamber, creating exhaust gases. Thrust, the forward force produced by the powerplant, is governed by the amount of exhaust gas expelled by the exhaust system. A butterfly valve known as the wastegate opens and closes depending on fuel consumption needs.
Exhaust gases exit the cylinders via the exhaust valves. A steel/nickel alloy is used to make the valves due to the high temperature conditions.
An EGT probe measures the engine gas temperature and sends the reading to an instrument on the flight deck. The EGT specifically measures the exhaust gases. It can be used to gauge the level of fuel consumption.
If they are not properly expelled through the exhaust system, exhaust gases can be detrimental to the overall safety of an aircraft. This is because exhaust gas contains large amounts of carbon monoxide. Carbon monoxide is deadly, odorless, and colorless. It is important that the exhaust gases do not leak into the cabin and cause harm to the passengers. Regular maintenance of the exhaust system is necessary to check for any cracks in the hardware.
The FAA sets out regulations for the amount of emissions an aircraft gives out during engine shut down and through the exhaust system. Smoke, hydrocarbons, carbon monoxide, and oxides of nitrogen are all monitored by the FAA. The Engine Fuel Venting and Exhaust Emissions certification requirements (14 CFR Part 34) apply to civil airplanes that are powered by aircraft gas turbine engines of the classes specified in the rule. The Clean Air Act of 1970 instructs the Environmental Protection Agency to work with the FAA to establish air pollution standards.
As well as venting air out of the aircraft, the exhaust system heats outside air for the purpose of heating the cabin. Exhaust heating systems are used on most light aircraft. The system routes exhaust gases away from the engine, through a muffler, and into the cabin. Heat from the exhaust system can also be used in the defrosting system controlled in the cockpit.
An additional benefit of engine exhaust system is noise reduction. Mufflers direct the engine’s sound waves through a set of tubes that are designed to partially cancel out the sound waves.
