A brief description of the initiative history of gas turbine aeroengine which quite few people know is given. In the 1940's USA, the former Soviet Union and old China all bought the license of Nene gas turbine aeroengine from Rolls Royce Co. UK. Today, after 50 years, USA and the former Soviet Union have become the greatest aviation industrial nations in the world. The fact has proved that attaching importance to the fundamental pre-research on aeroengine is one of the key points in aeroengine development. Therefore measures on how to attach importance to the pre-research to ensure aeroengine industrial prosperity in China are put forward in this paper.
