466011-0002 – Hartzell Engine Technologies Turbocharger Assembly

Available now on the Airparts.aero Marketplace.

Overview

The 466011-0002 is a genuine OEM, flight-critical turbocharger assembly, engineered for the powerful Lycoming TIO-540-AE2A engine. While offered by Hartzell Engine Technologies through their Quality Aircraft Accessories (QAA) division, the original equipment manufacturer is Garrett Motion (now part of Honeywell), the world leader in turbocharging technology. This is not a generic turbo; it is a precision-engineered forced induction system designed to compress intake air, allowing the engine to maintain sea-level horsepower up to its critical altitude. Featuring a high-temperature turbine, a high-efficiency compressor, and a robust bearing system, this turbocharger is essential for the high-altitude performance of aircraft like the Piper PA-46 Matrix and Mirage.

Key Features

• High-Altitude Performance: Its primary function is to use exhaust gas energy to compress intake air. This compensates for the decrease in air density at higher altitudes, allowing the engine to produce its full rated horsepower well into the flight levels.

• High-Temperature Superalloy Turbine: The turbine wheel and housing are fabricated from high-nickel superalloys (such as Inconel). These materials are chosen for their exceptional strength and resistance to creep and fatigue at the extreme temperatures of the engine's exhaust gases, which can exceed 1,600°F (870°C).

• High-Efficiency Centrifugal Compressor: The compressor wheel is precision-machined from a forged aluminum alloy, designed to efficiently compress the induction air with minimal temperature increase, maximizing engine power output.

• Robust Center Housing & Bearing System: Features a durable center housing that supports the common shaft, which can rotate at speeds exceeding 80,000 RPM. A high-speed hydrodynamic bearing system, lubricated and cooled by engine oil, ensures a long and reliable service life.

• OEM Specification: As a genuine OEM component, it guarantees the correct aerodynamic performance (A/R ratio), wastegate compatibility, and physical fitment required by the engine's original Type Certificate.

Applications

The 466011-0002 is a flight-critical component at the heart of the engine's induction system:

• Forced Induction: The sole component responsible for boosting the engine's manifold pressure above ambient pressure, enabling high-altitude flight.

• Engine Overhaul: A primary component that must be overhauled or replaced during any major engine overhaul to ensure the reliability of the induction system.

• Troubleshooting Performance Issues: A key component to inspect when diagnosing issues of low power, low critical altitude, or oil consumption.

Why Choose 466011-0002?

The performance and safety of a turbocharged aircraft at altitude are entirely dependent on the integrity of the turbocharger. A failure of this component will result in an immediate and significant loss of engine power. The 466011-0002 is the genuine OEM part, engineered and tested by the manufacturer to withstand the extreme rotational speeds and temperatures of this application. Using a genuine, traceable part is the only way to ensure the unit has the correct material composition and has passed the rigorous balancing and NDT inspections required for a flight-critical component spinning at supersonic speeds.

The 466011-0002 turbocharger is a marvel of energy reclamation. It is a self-contained system consisting of a turbine and a compressor connected by a common shaft. The hot, high-velocity exhaust gas from the engine, which would otherwise be wasted energy, is directed over the turbine wheel, causing it to spin at extremely high RPM. The compressor wheel, connected to the same shaft, spins at the same speed. It draws in ambient air, and its centrifugal design slings the air outwards at high velocity, compressing it to a higher density. This pressurized air (boost) is then routed through an intercooler to reduce its temperature before being delivered to the engine's fuel injection system. This process, known as turbo-normalization in many aircraft, allows the engine to think it is operating at sea level, producing full power even in the thin air of the flight levels.

Note: This is a flight-critical engine component. Installation must be performed by a certified A&P mechanic with experience in turbocharged engine systems, in strict accordance with the current Lycoming and Piper maintenance manuals. Proper lubrication and careful pre-oiling are essential for the health of the bearing system upon first start. All associated clamps, hoses, and gaskets should be replaced during installation.

The origin of AeroForce turbochargers began with systems and components developed by two companies — Garrett AiResearch and Rajay. Both progressed in ownership from Honeywell to Consolidated Fuel Systems/Kelly Aerospace. In 2010, the entire lineup was acquired by Hartzell Engine Technologies (HET), and AeroForce was born.

History

Hartzell Engine Technologies - Turbocharger Systems

As the largest manufacturer of general aviation turbocharging systems, Hartzell Engine Technologies supplies all of the major engine OEMs. Originally designed by Honeywell/Garrett and Rajay, Hartzell has invested in engineering development and software tools to create superior, proprietary system designs. While the turbocharger is the heart of a turbocharging system, the full system is comprised of multiple components working together. Each unit is inspected and certified, guaranteeing premium quality and serious boost.

Turbochargers

To match aircraft turbochargers to engine specifications, Hartzell offers several size classes. Spanning the engine range from the Rotax 914 to the largest Continentals and Lycomings used in pressurized aircraft, Hartzelland#039;s aircraft turbochargers are available for any size and performance requirements.

Turbochargers convert wasted energy, in the form of hot exhaust gases, into increased manifold pressure to increase the power available from the engine. The exhaust gases spin a turbine wheel at high speeds, commonly in excess of 100,000 rpm. The turbine wheel is connected to a compressor wheel that compresses the engine intake air, increasing its density.

Turbocharger Design

• Turbocharger consists of radial-outflow type air compressor direct-coupled to radial-inflow type turbine
• Turbine and compressor wheels, mounted on common shaft, rotate at same speed
• Wheel shaft supported by full floating bearings in cast iron center housing
• Pressurized lubricating oil, from engine lube system, delivered to shaft bearings through drilled passages in center housing
• Lubricating oil collected in center housing drains by gravity or is scavenged back to the engine crankcase
• Flow of gas directed to and from wheels by specially designed housings attached to center housing.

• No scheduled periodic maintenance of turbocharger required
• Good maintenance practices must be observed for engine lubrication, air intake, and exhaust systems for maximum turbocharger life and performance

• Turbine, driven by exhaust gas from engine exhaust manifold, drives direct-coupled compressor
• Compressor output (compressed air) is delivered through ducting to engine intake manifold
• Increased density of fuel/air mixture in engine permits increased power output

• Turbocharger speed and compressor output are controlled by use of an aneroid type controller and wastegate, to maintain sea level horsepower to high altitude. Bleed air from the compressor is also available for cabin pressurization options.
