Everything You Need To Know About Turbocharger Mounts In Aircraft

In aviation, performance and reliability go hand in hand. Pilots and maintenance professionals alike know that even the smallest components can make a major difference in how an aircraft performs in the air. 

One of those critical components is the turbocharger mount—a part that plays a key role in keeping the engine’s turbocharger stable, aligned, and functioning at peak efficiency.

At Acorn Welding, we understand how essential these mounts are for maintaining safe and powerful flight operations. Our experience working with aircraft exhaust systems, engine mounts, and turbocharger components gives us deep insight into what makes a turbocharger mount reliable and high-performing.

In this blog, we’ll walk you through everything you need to know about turbocharger mounts—from how they work to what to look for in terms of maintenance and upgrades

Importance Of Proper Turbocharger Mounting

Proper mounting of the turbocharger is crucial for several reasons:​

  • Structural Integrity: A well-designed mount prevents undue vibrations and movements, safeguarding both the turbocharger and adjacent engine components from potential damage.​
  • Performance Optimization: Correct positioning ensures efficient airflow through the turbocharger, enhancing engine performance and fuel efficiency.
  • Safety: Secure mounting minimizes the risk of turbocharger detachment or misalignment, which could lead to catastrophic engine failures or in-flight emergencies.​

Types Of Turbocharger Mounts

Turbocharger mounts can vary based on aircraft design and engine specifications. Common types include:​

1. Clamp-On Mounts

These mounts utilize clamps to attach the turbocharger to existing engine structures. They are often favored for their ease of installation and adjustability. These mounts are renowned for their lightweight design, weighing only 2.8 ounces, making them among the lightest in the market. ​

2. Bracket Mounts

Bracket mounts involve custom-designed brackets that bolt onto the engine, providing a dedicated platform for the turbocharger. This method offers enhanced stability and is often used in more permanent installations. 

For example, certain turbocharger brackets integrate captive nuts used for engine ring mount and aircraft suspension frame attachment, ensuring a secure fit. ​

3. Integrated Mounts

In some designs, the turbocharger mount is integrated into the engine's structure, offering a seamless and robust solution. This approach is common in engines where the turbocharger is a standard component rather than an aftermarket addition.​

Materials Used In Turbocharger Mounts

The choice of material for turbocharger mounts is critical, given the demanding operational environment. Common materials include:​

  • High-Strength Steel: Offers exceptional durability and resistance to thermal expansion, making it a traditional choice for many mounts.
  • Aluminum Alloys Provide a balance between strength and weight savings. For instance, 7075 aircraft aluminum is used in some clamp-on mounts for its lightweight yet sturdy characteristics.​
  • Titanium: Known for its high strength-to-weight ratio and corrosion resistance, though its higher cost limits widespread use.​

Maintenance And Inspection Of Turbocharger Mounts

Regular maintenance and inspection of turbocharger mounts are essential to ensure continued airworthiness and performance. Key practices include:​

1. Visual Inspections

Conduct routine visual checks for signs of wear, corrosion, cracks, or deformation. Pay particular attention to weld joints and attachment points. 

The Federal Aviation Administration (FAA) emphasizes the importance of inspecting V-band couplings and clamps, as these components can be obscured by heat protection features and may not be readily visible during pre-flight inspections.

2. Torque Verification

Ensure that all mounting bolts and clamps are torqued to the manufacturer's specifications. Over-tightening or under-tightening can lead to component failure.​

3. Alignment Checks

Verify that the turbocharger remains properly aligned with the engine's exhaust and intake systems. Misalignment can cause performance issues and undue stress on the mount.​

4. Replacement Of Worn Components

Replace any worn or damaged parts promptly. Utilizing high-quality replacement parts from reputable suppliers ensures reliability. For instance, Quality Aircraft Accessories offers a selection of aircraft turbochargers, wastegates, controllers, and valves, emphasizing the importance of quality in replacement components.

Considerations For Aircraft Owners And Technicians

When dealing with turbocharger mounts, consider the following:

  • Compliance with Regulations: Ensure that any modifications or replacements comply with aviation regulations and have the necessary approvals. The FAA provides guidelines on the installation of turbocharged engines, emphasizing the need for compliance with airworthiness requirements.
  • Quality Assurance: Source mounts and related components from reputable manufacturers known for their adherence to aviation standards. Companies like Acorn Welding specialize in aircraft engine mounts, offering services that include media blasting, discrepancy recording, and welding performed to AWS D17.1 Aerospace Welding standards.
  • Documentation: Maintain thorough records of inspections, maintenance actions, and replacements to ensure traceability and compliance.​
  • Training: Ensure that personnel handling turbocharger systems are adequately trained and familiar with the specific requirements of the aircraft model.
