How do Aircraft Pneumatic Systems Work?

Aircraft pneumatic systems use compressed air to perform various functions critical to the operation of an aircraft. The pneumatic system is typically powered by engine bleed air, which is extracted from the engine’s compressor section. The compressed air is then used to direct energy to operate the movement of certain aircraft components. Typical functions for the aircraft’s pneumatic system include:

Air conditioning
Cabin pressurization
Flight control systems for control surfaces like ailerons, elevators, and rudders
Landing gear
Anti-icing and deicing
Pressure regulation and distribution
Other systems such as starting systems for certain engines, cabin door operation, and air-driven hydraulic pumps.

Advancements in aircraft technology, such as the introduction of more electric aircraft (MEA), have led to a reduction in the reliance on pneumatic systems in some modern aircraft. However, many traditional aircraft still rely on pneumatic systems for their critical functions.

Aircraft Pneumatic System Components

Pneumatic systems in aircraft are essential for various functions, such as controlling flight surfaces, landing gear, and pressurization. Here are ten common pneumatic system components found in aircraft:

Air Compressor

The air compressor is responsible for compressing the ambient air to provide the required pressure for the pneumatic system.

Pressure Regulator

The pressure regulator maintains a steady and controlled output pressure from the air compressor to ensure consistent operation of the pneumatic system.

Air Receiver (Reservoir)

The air receiver, also known as a reservoir, stores compressed air to provide a buffer and maintain a stable supply during peak demands.

Check Valve

A check valve allows the flow of compressed air in one direction only, preventing backflow and maintaining system pressure integrity.

Shut-off Valve

A shut-off valve is used to isolate specific sections of the pneumatic system for maintenance or in emergencies.

Pressure Relief Valve

The pressure relief valve protects the pneumatic system from overpressure situations by releasing excess air when the pressure exceeds a predetermined limit.

Solenoid Valve

Solenoid valves are electromechanical valves that use an electric current to control the flow of compressed air to actuate various pneumatic devices.

Pneumatic Actuators

These are devices that convert the pressure of compressed air into mechanical motion, used for tasks such as operating flight control surfaces and landing gear.

Pneumatic Filters

Filters are employed to remove contaminants, moisture, and other impurities from the compressed air, ensuring clean and reliable operation of the system components.

Pressure Gauges

Pressure gauges provide real-time information about the pressure levels in the pneumatic system, allowing for monitoring and troubleshooting.

MRO Solutions for Aircraft Pneumatic Systems and Components

Predictive Maintenance: We utilize data to prevent problems before they happen. By regularly monitoring aircraft pneumatic components for early signs of wear and tear, we can repair pneumatic components as needed preventing costly replacement. New technology such as cloud computing and artificial intelligence has enabled accurate repair monitoring enabling engineers to create an effective maintenance schedule.
Pneumatic Component MRO: Regular maintenance, repair and necessary overhaul of pneumatic aircraft components. Utilizing revolutionary technologies like cold spray technology and predictive maintenance, pneumatic components can be serviced and repaired without necessarily replacing the components altogether. If replacement becomes necessary, we can create an identical replacement with print-to-build technology.
Airframe MRO: Includes work on the engine, landing gear, and other systems such as pneumatic systems.
Line Maintenance: Engineers complete line maintenance while an aircraft is in service for other repairs.
