This year, Honeywell Aerospace (Hall A, Stand 073) marks the 50th anniversary of the TPE331 turboprop engine, which powers single-engine aircraft around the world.
Designed originally by Garrett AiResearch and produced by Honeywell since 1999, the engine was first intended for the military, but was developed for multiple applications across military, regional airline, agricultural and general aviation aircraft.
Since the first commercial version received its type certification from the Federal Aviation Administration in 1965, the series has been produced in 18 models and 106 configurations.More than 13,500 TPE331 engines have been delivered to date, logging more than 122 million hours of flight time. Several conversion programmes are available to provide shorter take-offs, faster climbs, increased cruising speed and range, improved fuel efficiency, and lower operating costs.
With up to 1,650 shaft horsepower, the TPE331 is said to be the most cost-effective and powerful engine in its class – with the lowest cost of ownership. In addition, its simple single-shaft design provides an instant throttle response and best-in-class hot-and-high performance. There is no doubt that it is one of the most reliable and proven turboprop engines.Last year, Honeywell Aerospace was selected by PT Dirgantara Indonesia (Persero) to supply 11 TPE331 engines for its NC212 turboprop aircraft, in a deal worth US$7 million. The engines will be fitted to the company’s NC212-400 and NC212i aircraft.
The NC212-400 is a multipurpose aircraft designed to operate in hot and high-altitude conditions without compromising performance efficiency, while the upgraded NC212i, which is being produced at Bandung and has replaced the -400 model, is aimed at multi-mission requirements in the light transport segment. The TPE331 will address the needs of both aircraft, offering swift throttle response and increased fuel efficiency for maximum performance.Honeywell continues to work with aircraft manufacturers across the aerospace industry to ensure the TPE331 will meet the needs of the aviation community for the next 50 years.
