The actual state, future development principle and plan of china*s helicopter and transport aircraft are presented. The helicopter in production such asZ-11, Z-9, Z-8, and the transport aircraft in production such as Y - 5, Y - 7, Y - 8, Y -12 and N - 5 are reviewed. The development principle of three generations is put forward, i.e. to improve Z - 11, Z - 9, Z - 8 helicopter, develop 6-ton class helicopter, research 10-ton class helicopter, and to improve Y - 8, Y - 12, develop turbofan regional jet, develop in future heavy transport aircraft. The key technological plan for helicopter’s composite materials, rotor system, transmission system, crashworthiness, and engine is described. The paper points out that the development of China´s helicopter and transport aircraft should adhere to the combination of self developing with international cooperation, technology with trade, military with civil usage, and should be the nation´s long term development strategy.
