China Developing Homegrown 'Blue Whale' Tiltrotor
Unlike tiltrotors such the Bell Boeing V-22 Osprey or Leonardo AW609, the "Blue Whale" is a quad proprotor design.

Chinese state-owned aircraft company Avic is developing two variants of an “ultra fast” 270-knot tiltrotor code-named "Blue Whale," English-language newspaper China Daily reported late last month. Unlike tiltrotors such as the Bell Boeing V-22 Osprey or Leonardo AW609, the Blue Whale is a quad proprotor design. Avic chief helicopter designer Wu Ximing said that the aircraft would be "China's equivalent of the V-22 Osprey" and used for disaster relief, supply airdrop and search-and-rescue operations.
