Avicの中国直昇機設計研究所の「技術者」であるLi Linbiは、Z-20はフライバイワイヤコントロール、ならびに高地で運用する必要から動かす設計を備えている、と述べました。この研究所は、Avicのグループ企業であるハルビン航空機製造会社Z-20と共同で設計しました。

Liは、Aerospace DAILYにAvicが提供する記事で、5枚のメインローターブレードの空力設計は優れた特性を備えていると述べています。さらに、Liは設計の低抵抗についても説明しています。彼はその点を詳細に述べていません。しかし、天津の航空ショーに展示されたZ-20は、機体外部に装着品がなく、留め具もほとんどない外観が際立っていました—おそらく複合材料の広範な使用を示しているでしょう。


Avic is emphasizing the adaptability of the Z-20 utility military helicopter, as the Chinese army presents the type for close inspection for the first time.

Although the twin-engine Chinese helicopter looks much like a Sikorsky H-60, it may be larger, observation of one Z-20 presented at China Helicopter Expo here Oct. 10-13 suggested.

The Z-20 has fly-by-wire controls and a design that has been driven by the need to operate over high terrain, said Li Linbi, a “technical expert” of Avic’s China Helicopter Research and Development Institute. The institute presumably designed the Z-20 in association with Harbin Aircraft, the Avic unit that manufacturers it.

The aerodynamic design of the five-blade main rotor has superior characteristics, Li said in remarks provided by Avic to Aerospace DAILY. Li also pointed to the low drag of the design. He did not elaborate on that point, but the Z-20 parked at the Tianjin show had a remarkably clean appearance, with few fasteners—evidence, perhaps, of extensive use of composites.

The Z-20 is suitable for considerable further development, Li said, adding: “The basic transport platform can be quickly adapted to other missions.” It looks like such adaptation is already underway, since a Z-20 has been spotted on the flight deck of a warship and painted in light gray, as might be expected for a naval helicopter. Its tail also folded for shipboard storage.
