The H-IIB launch vehicle is an upgraded version of the current H-IIA launch capacity, which has two liquid rocket engines (LE-7A) in the first-stage, instead of one for the H-IIA. It has four SRB-As attached to the body, while the standard version of H-IIA had two SRB-As. One of the major design issue of H-IIB launch vehicle is increased prume heating due to clustering two LE-7A engines and four SRB-As, especially the interaction of engine prumes at high altitude. This paper describes the prume analysys method of H-IIB launch vehicle which is based on the flight proven method of the current H-IIA launch.
