Renard R.30

The Renard R.30 was a prototype trimotor airliner built in Belgium in 1931.[1] It was a strut-braced high-wing monoplane of conventional design with a fully enclosed flight deck and separate passenger compartment.[2] One engine was mounted on the nose, while the other two were mounted on the leading edges of the wings.[2] Construction was metal throughout, skinned in plywood and fabric.[2]

Role Airliner
National origin Belgium
Manufacturer Renard
First flight 1931
Number built 1

The R.30 was designed in response to a Belgian government requirement of 1929 for a long-range passenger transport aircraft to service Belgian Congo.[2] The design met the specifications laid down, but by the time it flew in 1931, it was judged already obsolete.[2] The single prototype, registered OO-AMK, was the only example built.[2]

gollark: <@!169992104406286336> DE is just useless oneupmanship. It always has to be better than other mods for no reason and generally just increases numbers uselessly.
gollark: *does not like Draconic Evolution*
gollark: Displaying a transistors ymbol, obviously.
gollark: bipolar junction transistor
