Aircraft manufacturing

Aircraft manufacturing during and after World War II

The company between 1939 and 1941 developed several gliders, autogyros and research aircraft for the Imperial Japanese Army. These are:

After the war, in 1954, the company built a gyrodyne, named Kayaba Heliplane. The development of this aircraft started in 1952 when Shiro Kayaba, the founder of the company, obtained the fuselage of a Cessna 170B and, over the course of two years, turned it into a convertiplane.[7]

Scandal
  • In October, 2018, Kayaba Industry said it had falsified data on the quality of some of its shock absorbers which were used in over 70 government and municipal office buildings including Tokyo Sky Tree, Tokyo Station and facilities for 2020 Summer Olympics since at least 2003 in Japan. In addition, all the faulty Japanese quake absorbers were only exported to Taiwan.[8][9]

gollark: I'm not sure about reproducible (the build config for a project probably won't specify precise versions for all compilation stuff) but declarative, yes.
gollark: Basically, you specify all your configuration in a declarative purely-functional language, which is then translated into actual system config.
gollark: One really cool thing I use on a server is NixOS.
