PT6C

High powered performance for medium-class helicopters.
1,600 to 2,000 shaft horsepower class
The latest technology for the new-generation medium-class helicopters and tiltrotors. Unmatched performance, continuing the PT6 legacy.

Overview

The PT6C-67 Series, with its latest advanced technologies, has been designed in the tradition of Pratt & Whitney's first helicopter engines to deliver outstanding reliability, durability and operating economics.

Setting a new standard in its class

The PT6C-67 Series sets a new standard in its class for power-to-weight ratio, fuel consumption, as well as durability in harsh operating environments. Advanced engine control ranging from Electronic Engine Control (EEC) to Dual Channel Full Authority Digital Engine Control (FADEC) further advances ease of pilot operation and maintenance diagnostics.

Versatility on a wide variety of applications

The 1,600 to 2,000 shaft horsepower class PT6C-67 Series has been produced in four models and its versatility has been demonstrated on a wide variety of applications. Over 1,372 PT6C-67C engines power helicopters in service with 197 operators in 68 countries in such applications as oil exploration, emergency medical service, maritime patrol, business and utility operations.

Features

The PT6C-67 is based on the PT6A-67 Series airline turboprop engine.

The PT6C-67 remains a PT6 in basic configuration, with its two-shaft layout consisting of a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the output shaft. It also incorporates the latest advanced compressor, combustion and turbine technologies to provide an impressive power-to-weight ratio while delivering low fuel consumption, low emissions, high durability and excellent operating economics. With its modern engine control ranging from Electronic Engine Control (EEC) to Dual Channel Full Authority Digital Engine Control (FADEC), the PT6C-67 Series provides ease of pilot operation and enhanced maintenance diagnostics to maximize engine refurbishment intervals.
