What Are Aircraft Engine Fire Protection Systems?

As aircraft traverse the sky at extreme altitudes where any major emergency would require a landing, it is crucial that they are designed with as much safety in mind as possible. One of the greatest hazards to aircraft safety is fires, those of which may cause a loss of lift, the risk of explosions, and other various hazards that must be avoided at all costs. As fires may source from numerous areas or spread, aircraft are designed with fire protection systems that range from structures to hand-held tools that crew members use. In this blog, we will discuss these fire protection systems in more detail, allowing you to better understand how flight operations are kept safe.

The engines of an aircraft are a major potential source of fires, making it crucial that such assemblies have increased fire protection. These risk-prone areas are called fire zones by manufacturers, and they are designated as a space where fire detection, fire extinguishing, and fire resistance solutions must be in place. Fire protection systems are often a requirement, especially for multi-engine turbine aircraft, multi-engine reciprocating aircraft, airliners, APU assemblies, and much more. Even if not a requirement, having some form of fire protection or extinguishing system is essential for safety in the instance of a fire.

While the extinguishing elements of a fire protection system are paramount for fighting a hazard, there must be detection systems in place to detect an overheat condition in the first place. Fire detector installations will be present in various zones of the aircraft, and they may come in the form of overheat detectors, rate-of temperature-ruse detections, or flame detectors. Once any one of these detectors determines that there is an unsafe condition or fire, it will alert the crew or actuate a fire fighting system if present.

While fires are not common on aircraft, they can occur as a result of either thermodynamic or mechanical issues. In terms of thermodynamic issues, the risk of a fire is at its highest when engines reach extreme temperature levels that go beyond safe limits. As excessive heat builds up, engine components like turbine blades may melt, leading to a loss of thrust. As more overheating and failure occurs, the aircraft structure and its systems may begin to lose performance and integrity as the aircraft faces a loss of operations.

When it comes to mechanical issues, fires generally occur because of fractured or thrown blades that cause overheat conditions to occur. Thrown blades may also puncture the tail cone of the aircraft, causing an overheat condition. Even more dangerous, the puncture may cause a leakage of flammable fluids which can lead to an increased amount of danger.
