NASA is actively researching its evidence and thoroughly testing the potential for the most rare, but serious threat to aviation - the freezing that occurs when flights fly over the top. This investigation is aimed at improving the safety of irrigation workers.
The problem of hypothermia of great specks.
The phenomenon known as “supercooled large droplet icing” occurs when flights fly through the gloom, which avenges unexpectedly large droplets of water. These droplets, when the temperature is low, are rarely lost. Flying through such drops, stinks can freeze quickly on the surfaces of the flytak, not protected from the ice..
The water is over-cooled and it becomes wider in the cold. Droplets can keep temperatures below 0°C without freezing or touching saws or other microscopic particles, which may crystallize.. Letaki are designed for irrigation in typical freezing washes, where the diameter of the droplets varies from 2 to 100 microns (for example, human hair has a diameter of about 70 microns). However, in rare outbreaks, gloom can cause overly large drops with a diameter of up to 2000 microns (as you have once been sunk under the cracked planks, you are familiar with such drops on the plain. These significantly larger droplets can be impacted or sprinkled on the back of the flytak, including plots in the area where traditional frost protection systems operate.
Testing in a wind tunnel.
A series of tests conducted at the Icing Research Tunnel (IRT) at NASA's Glenn Research Center helps the American aviation industry become more efficient. Aviation rope is used on engineering tools to design flights. Current instruments work well for typical colds, but engineers have to question their accuracy when dealing with the physics of supercooled great drops.. To find out the evidence, NASA is expanding its capabilities to develop and experiment with experiments for testing in IRT..
NASA researchers experimented with completely new probes that help calibrate the size of the droplets that form near the pipe. These probes can “scan” droplets with a diameter of up to 45 microns and analyze their sizes in real time. NASA compares these results, which were obtained by reactive post-processing of data to image droplets from the pipe, with the results of another probe, which shows droplets with a diameter of less than 45 microns. In this way, a new spectrum of different sizes of speckles will be visible.
This series of tests is an important milestone for the Subsonic Flight Demonstrator (SFD) project, which is part of NASA's Mission Research and Technology Directorate. A detailed analysis of the collected data is exciting, and the NASA project team will share the results with the wider aerospace community once they are completed.
