摘要
For cooling down a cryogenic model, provided for testing in a cryogenic wind tunnel, to the wind tunnel temperature and for performing mounting work and configurational changes on the cryogenic model, there is provided a working chamber which is supplied with warm air so that working personnel can enter it. The working chamber contains an insulating box, made from heat-insulating material, which has an open top and into which cold air is injected. The insulating box accommodates the cryogenic model under cold air conditions. Persons can perform manipulations on the cryogenic model while leaning over the edge of the insulating box. The cryogenic model is held on a holder which can be lifted upwardly out of the insulating box. Removal of the cryogenic model from the working chamber is possible by opening a top door.
