Charles Lin, founder of Yoshine Helicopters, has intended to develop an easy, safe & economical personal helicopter that everybody can fly, like the one below, the American Helicopter Dream of the 1950's.
《 "1950年代" 美國人的飛行夢:“全民個人直升機” 》
By 1992, the first of such a “Helicopter” was complete and sold to a UCLA professor in LA for commuting to campus from his suburban hill home where he also kept horses and a swimming pool. 1992年,第一架 "全民直升機" 由加州大學UCLA一位教授買去,作為他從其洛杉磯郊區有馬有游泳池的山上住家飛行到學校上下班的交通工具,一天節省了一個多鐘頭的開車時間。
《1992年代開始外銷的 “全民直升機”》
By 1994, the first such a improved personal helicopter made its public flight demo at the Florida "EAA Sun-n-Fun" Airshow, demonstrating the ultralight helicopter's "Autorotation" capability to land safelywith engine quits from10 to 25 feetabove the ground as shown in the video below: 1994年第一代小量產全民直升機,在美國佛羅里達州的 “EAA” 航展,首次公開飛行表演,展示超輕直升機獨特的安全“自轉降落”功能,可從3至8公尺的飛行高度、引擎熄火之時,讓直升機“自轉著陸”,因此受到歐美紐澳日等國人士的歡迎,開始外銷:
“Autorotation" is an inherent characteristic and ability of a “helicopter”, as learned from an ancient Bamboo toy. Once you've learned and mastered the autorotation procedure, you will be able to land a helicopter safely, when the engine "quits", even at the very low height of 10 to 25 ft ! 這是直升機雷同 “竹蜻蜓” 固有的“自轉” 特性,一旦學會飛直升機,學得此獨特的“自轉著陸”技巧,就可以在引擎熄火的情況下,控制直升機 “自轉” 安全著陸!
"Autorotation" capability is what makes helicopters “inherently safe”, once you've learned and mastered the "autorotation" procedure. 這種直升機“自旋著陸”功能,可讓飛行員在直升機引擎失去動力時安全降落。這就是為何「直升機」比其它「垂直起降飛行器」安全的主因。
In 1996, Charles Lin was invited to the "Monte Carlo Yacht & Helicopter Show" where Prince Rainier of Monaco happened to have come personally to witness the Personal Helicopter presented locally by our European sales partner. 1996年,歐洲代理商參與 “蒙地卡羅遊艇直升機展”,展出第一代台灣出口 “全民直升機”,巧遇 “雷尼爾親王” 到場視察,聽取林正祥為"全民直升機"的介紹:
爾後,美海軍某單位,看上此超輕直升機載重百公斤潛力,採購樣機,改裝成第一代無人「火箭」直升機:
In 1999, 2-seat version were developed with the FAA approval as an “helicopter” trainers. 1999年,在各國需求的及FAA的批准下,雙座 “警用” 訓練直升機,開始外銷歐美紐澳印度等國:
In 2002, with help from AIDC, Yoshine's first "Coaxial Unmanned Helicopter" took off in Taichung, Taiwan, and Yoshine was invited to exhibit at the HeliTech 2003, in Duxford, UK. 2002年,在台中漢翔公司提供飛行場地的協助下,世界首創第一代載重愈百公斤的「“CDS" 共軸無人直升機」在台中起飛。消息傳出“HeliTech2003”特邀祐祥到英國展出“共軸直升機驅動系統” 結構(下圖):
