Opis:
Monochrome photograph of a snow sleigh or ice sled powered by an engine designed by Henri Coandă. The sleigh was owned by Grand Duke Cyril of Russia. Its powerplant was a piston engine which drove a ducted fan or "suction turbine", the same power plant that Coanda had exhibited in 1910 on his first aircraft, later called the Coandă-1910.
