Mixer blades interrupt airflow for rapid testing of insulating materials. Device for producing periodic blasts of heated air used for rapid testing of flexible insulating materials. Used to compare materials and to select candidates for more detailed testing in wind tunnels.
Thermally radiating blanket of stepped thickness distributes heat over insulation sample during thermal vacuum testing. Woven of silicon carbide fibers, blanket spreads heat from quartz lamps evenly over insulation sample. Because of fewer blanket layers toward periphery of sample, more heat initially penetrates there for more uniform heat distribution.
