Abstract:The joint between after fuselage and the vertical stabilizer for commercial aircraft is very important, which transfers the load from vertical stabilizer to fuselage. The joint structure design is based on load, methods,damage tolerance, repairable, weight, cost, etc. This paper analyzes the mature concept of representative aircraft and the joint scheme of developing aircraft, and makes a summary of three main schemes. The advantages and disadvantages were given by comparing. The methods could be used as reference for the joint between after fuselage and the vertical stabilizer of commercial aircraft.
