類飛碟飛行器AVROCAR VZ
[size=16px]關於飛碟的傳說很多,最後大多被證明只是人們的想像,但加拿大 Avro 公司(就是曾經研製CF-105 Arrow箭式攔截機的那個公司)的Avrocar 確實很像飛碟,這大概是最接近飛碟的飛行器了。Avrocar 就像一個上面圓渾的大碟子,中間是進氣的圓孔,周邊是一圈小噴嘴。發動機產生高壓排氣,通過周邊的噴嘴噴出,拉動上方氣流,沿上表面高速從中心向周邊流動,在飛行器靜止的時候就可以形成康達效應(Coanda Effect)產生升力,達到垂直起飛。垂直起飛後,重新調整周邊噴嘴的氣流分佈,就可以實現噴氣推進,一旦達到一定速度,飛碟本身的形狀就可以產生氣動升力,爬升並轉入正常飛行。

Avrocar 引發了很多關於飛碟和外星人的聯想 。
儘管“飛碟”在理論上可以飛起來,但Avrocar 從來沒有真正翱翔於天際,離開地面後飛行穩定性的問題一直無法解決。
Avrocar 是美國陸軍 VZ 系列垂直起落研究機中的一個,出資 Avrocar 的美國軍方對飛碟的應用是很用心的。在試飛中演示了垂直起落能力,但無法飛的太高,飛的太高飛行控制就顯得力不從心,飛行穩定性無法解決,最後不了了之,徒留一段飛碟的佳話。
