Notable Product Categories

Auxiliary Power Units (APUs)

Honeywell is the world’s largest manufacturer of APUs, valued for their fuel efficiency and ability to power multiple systems simultaneously. With more than 36,000 units still in service, some of their many notable models include the:

131-9 Series APU: Standard on the Boeing 737NG and Airbus A320 family, the 131-9 series features a two-stage axial turbine and a single starter/generator that transitions to electrical generation once running.
36-150 APU: The 36-150 APU provides compressed air and shaft power simultaneously or independently, supporting engine starting, air conditioning, and anti-ice systems.
HGT1700 APU: Derived from Honeywell’s 331 series, the HGT1700 APU incorporates weight reduction, fuel usage improvements, and reduced emissions to suit the Airbus A350 XWB and align with industry-wide environmental goals.

Engines

Honeywell is also renowned for its various turbofan, turboprop, and turboshaft engines that overall present lightweight construction, lower emissions, and great fuel efficiency. Used on a multitude of platforms, Honeywell’s engines have altogether logged millions of hours in service. Popular engine options include the:

HTF7500E Turbofan Engine: Known for powering Embraer Praetor 500 and 600 business jets, the HTF7500E engine delivers a bypass ratio of 4.2 for optimized thrust while maintaining low noise levels.
TPE331 Turboprop Engine: One of the longest continuously produced turboprop engines with thousands of units in operation worldwide, the TPE 331 engine is renowned for its strong performance and fuel economy.

Flight Control Actuation

Honeywell produces an array of hydraulic, pneumatic, and increasingly, electromechanical flight control actuation systems. Across the board, Honeywell actuators share the traits of high responsiveness, built-in redundancy, fail-safe architecture, and compact designs. Furthermore, their certification-ready designs streamline integration and qualification processes for both established aircraft platforms and new-generation airframes.

In particular, their electromechanical actuation systems are engineered for hundreds of micro-adjustments per second in response to fly-by-wire computers. Compared to conventional hydraulic or cable-based systems, EMAs eliminate the need for complex fluid management infrastructure, offering substantial benefits in energy use, weight reduction, and ease of maintenance. Because of this, EMAs are an ideal solution for the rise of urban air mobility (UAM) and eVTOL aircraft.

Brakes

Honeywell’s landing gear wheels, brakes, and associated components are compatible with many aircraft, all largely sharing a pointed focus on reducing maintenance requirements and cost of ownership. Specifically, a few of their most notable contributions to braking technology are the:

Cerametalix Brakes: Honeywell's Cerametalix technology combines the benefits of carbon and metal materials to produce brakes that offer high energy absorption and fantastic durability. Cerametalix brakes are among the most utilized globally, with Honeywell claiming they represent more than 50% of the world's commercial steel brake business.
Carbenix Brakes: The Carbenix series leverages carbon friction materials to create a cost-effective yet durable solution that presents great stopping performance and reduced weight.
