Abstract：Ω type composites stiffened panel has been widely used in large civil aircraft due to its structural advantage.
But some difficulties exist in how to pressurize these Ω type stiffened panels during the co-curing process. Especially
there are strict airworthiness compliance review requirements in the field of civil aviation products manufacturing, thereby
further increasing the manufacturing difficulty. After a number of tests, the group decided to adopt thin-walled rubber balloon
forming method to manufacture the Ω type stiffened panel in order to meet design requirements and airworthiness requirements
finally.
