The Reuleaux Triangle was designed by the German engineer Reuleaux in the 19th century.
After that, the mathematics community extensively studied its utility. By the twentieth century, it was cited in mechanical engineering,
The most famous example is the application in pistonless engines, Volkswagen Beetle, Master Mazda RX7,
Both use this new design of the engine (Rotary Engine / Wankel Engine).
postscript:
Unexpectedly to study the Lego Rotary Engine built by Japanese engineer Akiyuki,
It will be related to Ryosuke Takahashi's Mazda RX7 from "Initial D".
This sports car is really cool, in addition to the appearance of the body,
The main reason is that its exhaust pipe will spit fire during competitions.
Unfortunately, the film of "Initial D" did not emphasize this point with the lens...
The rotary engine is the key to the fire-breathing exhaust pipe of Mazda RX7!
魯洛三角形 (Reuleaux Triangle)是十九世紀德國工程師Reuleaux的設計,
之後數學界廣泛研究它的效用。到二十世紀,被引用於機械工程,
最著名的就是應用3在無活塞引擎,福士甲蟲車、萬士達Mazda RX7,
均使用了這款轉子引擎 (Rotary Engine / Wankel Engine)。
後記:
想不到研究日本工程師Akiyuki砌出的轉子引擎(Lego Rotary Engine),
會跟《頭文字D》高橋涼介的Mazda RX7扯上關係。
這輛跑車所以這麼酷,除了車身外型之外,
最主要是因為它的排氣管在賽事中是會噴火的,
可惜《頭文字D》的影片並沒有用鏡頭強調這點......
而轉子引擎就是Mazda RX7排氣管會噴火的關鍵!
