TEST MODEL PROCESSING ROOM FOR LOW TEMPERATURE TEST IN WIND TUNNEL

摘要

PURPOSE: To reduce the energy required for maintaining a model at a low temperature by providing a working chamber into which a cooling gas can be injected and which has a heat insulating box made of a heat insulating material and having an opened top, can be heated with dry air, and can be blocked. CONSTITUTION: In a working chamber 10, a heat insulating box 13 for housing a test model 14 in a heat insulating state is provided. The box 13 has a bottom wall, side walls 17 protruded from the bottom wall, and an opened top. A groove section 21 having an opened top houses a holder 24 for attaching the model 14. The holder 24 can be moved in the vertical direction together with the model 14 and can be displaced in the horizontal direction. At the end section of the holder 24 on the box 13 side, a door 22 having a plurality of wing sections 22a and 22b which are turned in the opposite directions at the time of opening the door 22 is provided. The box 13 is composed of module walls 30 and each wall member of the walls 30 is composed of a heat insulating central layer made of a material having a small heat mass coated with a coating of aluminum, etc., so as to prevent the contamination of the dry air in the chamber 10.
