Phase 2 Establishment of the comprehensive engine technology (1992 to 2003)

Design and part manufacturing technologies had been established and developed for an engine (Model HF118-2) which was powerful enough to meet the engineering and type certification requirements.


HFX-01 development

history02_ph01

HFX-01, an engine which was built with a conventional engine structure.

1992 - 2000

The target performance and weight goals were achieved for the first time by applying the turbofan engine system, which was widely applied in the jet engine industry, and using common materials.

High-altitude test with a large aircraft (HFX-01)

Flight tests were conducted to verify the engine performance and functions under actual flying circumstances, which included a low temperature, a low atmospheric pressure, or load variations such as a position change and weightlessness caused by a fuselage movement, some of which are difficult conditions to reproduce on the ground.


HF118-2 Development

history02_ph03

Turbofan engine HF118-2 developed by utilizing the accumulated technologies and know-how.

1998

We challenged to improve the weight, fuel efficiency and emission to gain more competitiveness.

HF118-2 Technology Development

Weight Reduction
A weight reduction of approximately 80% was achieved as compared to conventional systems. This was achieved by integrating the fuel-control technology developed for Honda automobiles and a fuel pump system into a single structure.

Fuel efficiency
Despite the size of the engine, we developed a compressor that can draw a large amount of air and compress an air at class-leading performance. It was achieved by developing Honda’s original computational fluid analysis software.

Low Emission
Applied Honda's traditional combustion method (CVCC) to combustor and achieved class-leading emission results.

Flight test with HF118-2 retrofitted on both sides of a small business jet engine.

November 2003

The first flight was achieved by only using Honda’s turbofan engine.


history02_ph05

Flight test conducted on experimental aircraft (HondaJet) with HF118-2.

December 2003

We succeeded in the first flight on the experimental aircraft (HondaJet) equipped with HF118-2.
(This flight was 100 years after the Wright brothers' first flight.)
