This paper shows system design of payload fairing about separation device, skin sizing, configuration, thermal protection, acoustic blanket and weight. Payload fairing is mainly composed of skin structures which support structural loads and separation devices which take charge of fairing separation. Skin is composed of composite sandwich and metal frame. After pyro-explosives cut fasteners which connect each half fairing, fairing separation is accomplished by hinge rotations which are rotated by spring forces. The static strength tests regarding fairing are composed of three tests. The object of the first test is fastening parts which are related to pyro energy level, the second is an external pressure test and the third is a bending test. Separation test also will be performed after limit load which simulated aerodynamic loading during flight.
