Abstract: | A series of questions occurred such as aerodynamic,combustion,cooling and structure when the aero-gas turbine nozzle was installed,so aerothermodynamics and structure feasibility analyses were conducted.The new flowpath design,internal flow and outflow cooling systems designs were conducted by the means of integration design for the nozzle and aircraft afterbody,and the designs of quick-release ring and multiple structures were improved.The experimental verification was conducted and good effect of installation was obtained as well as the services given some favorable comment. |
