    Abstract

    The present day combat airpalne has its engine in the fuselage and the air intake at the fuselage nose or an the sides, with the engine eahaust at the fuselage end. While testing models of the airplane of this type, simulatioin of intake flow and jet exhaust are two of the important problems facing the wind tunnel engineer. This is because the space within the model fuselage is almost completely occupied by the balance necessary for registering the load, resulting in very little space for the pace of the air , if it is taken in through the intakes. This necessities closing of the intake opening and providing fairings for the closed intake while making force measurements.
