From the above analysis,no matter from the historical data of yield and output value of rotorcraft or forecast for the next 10 years,the world rotorcraft market basically is still in the giants monopoly of United States and the European,where competition is mainly between them.Including Russia and China,rotorcraft industry development space will be strong compressed from the United States and Europe.The outlook is not optimistic,how to find rotorcraft industry development in our country is what we need to seriously study in the United States and Europe rotorcraft industry giants. 2.2 Navigation aircraft and airport development. The development of navigation aircraft is remarkable in European countries,while is just sprout in China.As the development of air taxi,there will be more civil airport for gyroplane to take off and land and consequently increase the production rate of navigation and then improve the operate environment of air taxi reversely. Currently there is about 340000 navigation aircrafts around the world,and the 10
