An objective of the present invention is to provide a machine for a close-to-life simulation of heating a basal portion of a real rocket by exhaust gas. Provided is a complex heating apparatus which simulates radiant heat and convection heat close to reality in accordance with a heat transfer phenomenon where radiant heating by the exhaust gas of a rocket engine occurs at first, and, after a predetermined time, convection heating by the direct contact of high temperature gas occurs additionally, when the basal portion of a ballistic body is heated. |
