由三七二厂和六○二所共同研制的直八机,于一九八五年十二月十一日在景德镇首飞成功。 当天下午,雪霁天晴,阳光灿烂。试飞机场白雪皑皑,彩旗飘舞,人群云集。国防科工委科技委副主任叶正大、航空工业部副部长王昴、江西省委副书记刘方仁等领导同志以及有关兄弟厂所院校的领导、专家、教授观看了试飞。中央各大新闻单位驻江西省记者、江西省和省属市新闻单位的记者也前来采访。三时许,三颗绿色信号弹腾空而起,顿时,机声轰鸣,一架草绿色的大型直升机徐徐上升,紧接着就干脆利落地完成一个又一个的规定飞行科目——悬停、横飞、侧滑、盘旋……,然后按时、准确、安全地返回地面。 直八是单桨式带尾桨的大型直升机。该机具有飞行性能较好、使用寿命较长、飞行安全、操纵容易、使用维护方便等特点。可广泛用于运输、巡逻、通讯联络、救护等;加装适当的装备后,还可适用于地质勘探、测绘、森林灭火和架设高压线等方面;又能改装成客机。 直八的诞生,为我国国民经济建设和国防现代化建设提供了新装备,同时也缩短了我国与国外直升机技术的差距。
The eight straight machines jointly developed by the 372 factory and 602 were the first to successfully fly in Jingdezhen on December 11, 1985. In the afternoon of the same day, the snow was clear and sunny. The pilot airport was snowy, flags fluttered and crowds gathered. Leaders, experts, and professors from the leaders of the Institute of Science, Technology and Industry for National Defense, Deputy Director of Science and Technology, Ye Zhengda, Vice Minister of Aviation Industry Wang Wei, Deputy Secretary of the Jiangxi Provincial Party Committee Liu Fangren, and related brothers factories attended the test flight. Reporters of the major central news agencies in Jiangxi Province, Jiangxi Province, and provincial news agencies also came to interview. At three o’clock in the morning, three green signal bombs burst into the sky and suddenly the aircraft roared loudly. A large grass-green helicopter slowly increased, and immediately afterwards it completed one by one of the prescribed flight subjects - hovering, flying, Slip, hover, ... and return to the ground on time, accurately, and safely. Straight eight is a single-propeller type helicopter with a tail rotor. The aircraft has the characteristics of good flight performance, long service life, flight safety, easy operation, and convenient use and maintenance. It can be widely used in transportation, patrolling, communication, rescue, etc.; after installing appropriate equipment, it can also be applied to geological exploration, surveying, forest fire extinguishing and erection of high-voltage lines, etc.; and can be converted into a passenger aircraft. The birth of Direct Eight provided new equipment for China’s national economic construction and modernization of national defense. It also shortened the gap between China’s and foreign helicopter technologies.
