Do you remember that scene in E.T. where the kids fly away on their BMXs? After seeing it, did you too want to pedal your bike down the street, over your house and past the moon?
Well, now that fantasy can be reality with the invention of the Paravelo flying bicycle.
A pair of flight enthusiasts, John Foden, 37, and Yannick Read, 42, have devised a two-wheeled bike—named the Xplore Air Paravelo—that transforms into an aircraft. The British inventors say it is the world's first fully functional flying bicycle.
The machine can travel at speeds of up to 15 miles per hour on the road and 25 miles per hour in the air, reaching altitudes of up to 4000 feet.
The flying bicycle looks like a conventional bike connected to a lightweight trailer, which houses1) a giant fan2), fuel for the contraption's3) engine and the flexible fold-away wing. Both the airframe and bike are made from aircraft grade aluminum.
The bike can be disconnected from its trailer for inner city use, then docks4) to form a \"para-trike\" for take-off. In order to fly, the bike and trailer are fastened together, the wing is unfurled5) and an electric starter fires the biofuel-powered 249cc motor. Tired Tour de France6) competitors might want to consider this option before taking on a particularly daunting7) hill climb.
The Paravelo also has a built-in tent, perfect for festival-goers. The inventors say this is a perfect addition because it enables the owner to detach the tent, set up camp, and then cycle off to explore the area.
The Paravelo needs a long stretch of open ground, clear of obstructions for take-off. Once airborne8) it can stay in the air for up to three hours. Once it's in the air, the flying bicycle's inventors say that it controls like a conventional fan-powered paraglider9).
The fan can also be detached entirely from its housing and strapped directly onto your back. Worn like this, no license is required to fly it in many countries—including the U.S. and the UK—but the United States Powered Paragliding Association strenuously10) recommends proper training.
So unless you have done it before, jumping off the closest cliff in your new Paravelo is not recommended.
\"The Wright brothers were former bicycle mechanics so there's a real connection between cycling and the birth of powered flight that is recaptured in the spirit of the Paravelo,\" says co-creator John Foden.
The bicycle is small enough to be taken on public transport, and can be stowed11) in a garage or carried up stairs and stored at home.
Foden and Read hope that at $16,000 the Paravelo will appeal to inner-city flight hobbyists, and believe that it may also be useful as a \"cost-effective aerial reconnaissance12) vehicle for forest rangers13) and border patrols\".
你還記得電影《外星人E.T.》里孩子們騎著小輪車凌空飛馳的場景嗎?看到這個之后,你是不是也想踩著你的腳踏車,騎上街頭,飛越房屋,飛過月亮呢?
好了,現在會飛的自行車Paravelo這一發明可以使這個幻想成真了。
兩個飛行愛好者——37歲的約翰·福登和42歲的揚妮克·里德——發明了一款能夠變身為飛行器的雙輪自行車,并為其取名為“Xplore Air Paravelo”。這兩位英國發明者稱,這是世界上第一輛真正具有飛行功能的自行車。
這款自行飛車在陸地上行駛時時速可達15英里(編注:約24公里),在空中時速可達25英里(編注:約40公里),飛行高度可達4000英尺(編注:約1220米)。
該自行飛車看起來像一輛傳統的自行車連接著一輛輕質拖車,拖車里裝有一個巨大的螺旋槳,還有這個奇妙裝置的發動機所用的燃料和一個靈活的折疊機翼。機體和自行車均采用航空級鋁合金制成。
人們可將自行車與其拖車分離供市內出行使用,之后又可將兩者對接成“三輪傘車”以便起飛。為了能夠飛行,自行車和拖車要固定在一起,機翼要展開,電啟動器要發動0.249升排量的生物燃料動力內燃機。疲勞的環法自行車賽參賽選手在挑戰令人膽怯的爬坡賽段之前,或許想考慮一下這款自行飛車。
Paravelo還配有一頂內置帳篷,這對于假日出行者來說無疑很完美。兩位發明者認為這是個絕妙的附帶品,因為車主可以把帳篷卸下來安營扎寨,然后騎車探索周邊環境。
Paravelo需要一長段沒有障礙物的開闊地帶才能起飛。一旦飛起來,Paravelo最長可在空中待上三個小時。自行飛車的兩位發明者說,Paravelo一旦飛到空中,操作起來就和傳統的風機動力滑翔傘很像了。
自行飛車的螺旋槳也可以全部從防護外殼里取下來,直接綁到你背上。這樣一武裝,你無需任何執照就能暢飛多個國家,包括美國和英國。不過,美國動力滑翔傘協會強烈建議你進行適當的訓練。
因此,除非你以前接受過這樣的訓練,否則建議你還是不要騎著新買的Paravelo從最近的懸崖一躍而下。
“萊特兄弟原本是自行車技師,因此可以說,騎自行車和動力飛行的發明之間確實存在聯系。Paravelo的理念正是這種聯系的再現。”自行飛車的聯合發明者約翰·福登說。
這款自行飛車的體積夠小,可以帶到公共交通工具上,也可放進車庫或搬上樓梯置于室內。
福登和里德希望這款標價1.6萬美元的Paravelo自行飛車能贏得城市飛行愛好者的青睞。他們認為,這款自行飛車也可作為一種“高性價比的空中偵察工具,供護林員和邊境巡邏人員使用”。
