What is "tonka"

Tonka is an American producer of toy trucks. Maisto International, which makes diecast vehicles, acquired the rights to use the Tonka name in a line of 1:64 scale diecast vehicles, featuring mostly trucks. The Winifred Museum in Winifred, Montana, has a collection of more than 3,000 Tonka toys.

Tonka (also TONKA-250 and R-Stoff) is the name given to a German-designed rocket propellant; it has also been used by North Korea and (under the name TG-02) by the Soviet Union.

Its composition is approximately 50% triethylamine and 50% xylidine, with nitric acid as a hypergolic oxidizer. Its use by amateurs is not advised, as the exact proportions of ingredients necessary for the mixture to work as desired, rather than fail catastrophically, is a function both of the ingredients' purity, and of their temperature during use.

Its name is a reference to the tonka bean; as it was invented during the Second World War, it has no connection to the similarly named toys.

Triethylamine / xylidine mixtures composed the TX and TX2 fuels of the French SEPR rocket engines of the 1950s, used for auxiliary rocket power in the Mirage IIIC. In aircraft use, TX fuels were later replaced by non-toxic kerosene jet fuels, simplifying fuelling of the aircraft. Little change was required to the engines but as this was no longer hypergolic with nitric acid, a small tank of TX was retained for ignition.

Tonka is an American toy company.

Tonka is a 1958 Walt Disney Western adventure film about the US cavalry horse that survived the Battle of the Little Big Horn. Also released under the title A Horse Named Comanche, it stars Sal Mineo as a Sioux who fought there. It was filmed in Bend, Oregon, and distributed by Buena Vista Distribution.

The film is based on the book Comanche: Story of America's Most Heroic Horse by David Appel, which tells an imaginary story of the Indian and US Cavalry owners of the horse of the title.
