Heating long objects such as rocket engines - involves guide vanes to guide air stream around objects

摘要

The equipment (10) is used for heating long objects such as rocket engines. There is a housing (14) with racks to support the rocket engines (12). The housing has an inlet (18) at one end and an outlet (20) at the other end. A fan (22) at the outlet end draws a current of warm air through the housing. At the housing inlet (18) or at the outlet end, or at both ends curved vanes are fitted. These vanes impart a swirling motion to the airstream so that the air flows around the rocket motors as it flows from one end of the housing to the other. USE - Heating long objects, such as rockets.
