- Summary:
- AbstractIn Central Institute of Aviation Motors (Moscow, Russia) over the past few years, work has been carried out on upgrading the test cell to simulate the conditions of ice crystals and mixed phase in accordance with regulatory requirements. The key feature of this test cell is that it is a high-altitude climate test rig with the possibility of creating altitude conditions up to an altitude of 15 km, as well as creating a high-speed stream up to 0.85 Mach number and temperatures up to 40°С. The diameter of the wind tunnel of this test cell is 1.02 meters. The layout of the test rig includes a manifold for bringing ice crystals into the stream, as well as a water spray manifold. With the help of a water spray manifold, it is possible to produce supercooled droplets in the stream. Using two collectors at once gives opportunity to create a wide range of conditions for both ice crystals and mixed phase. Ice crystals are obtained by the method of mechanical crushing of an ice bar by a cylindrical cutter. It is possible to obtain the required median size of ice crystals MVD = 50200 μm by changing the feed rate of the bar, as well as the frequency of rotation of the cutter. It is also possible to adjust the flow of ice crystals. Methodical study of the calibration tests issues of stream containing ice crystals was performed. Cloud uniformity distribution was received for three different methods
