Welcome to the "Blast from the Past" Newsletter! Reviews of the NACA-era aircraft icing publications, 1915 to 1958. - Latest post: Bodies of Revolution https://icinganalysis.com/bodies-of-revolution.html - Interesting finds: An accident of an experimental Lockheed XP-38, attributed to carburetor icing, 1939. https://www.thisdayinaviation.com/11-february-1939/ - Most popular posts (so far...): #3: "Super-Cooled Water Droplets in Rising Currents of Cold Saturated Air" https://icinganalysis.com/super-cooled-water-droplets-in-rising-currents-of-cold-saturated-air.html "It is possible to develop this theory to cover also growth of water droplets during the adiabatic expansion of a rising mass of saturated air." - Upcoming re-posts: The relentless reposting of revised posts continues on Mastodon https://historians.social/@icinganalysis (and, less reliably, on LinkedIn). 10/23: "A Langmuir B drop size distribution is (almost) a normal distribution" 10/25: NACA-TN-2904 "Impingement of Water Droplets on a Cylinder in an Incompressible Flow Field and Evaluation of Rotating Multicylinder Method for Measurement of Droplet-Size Distribution, Volume-Median Droplet Size, and Liquid-Water Content in Clouds" 10/27: NACA-TN-2903 "Impingement of Cloud Droplets on Aerodynamic Bodies as Affected by Compressibility of Air Flow Around the Body" - Upcoming Aircraft Icing Events: Submissions for papers open October 3, and close December 13, for the AIAA Aviation Forum, July 29 to August 2, 2024, so get typing! https://www.aiaa.org/aviation/presentations-papers/call-for-papers#atmospheric-and-space-environments - Quote of the week: "In spite of the simplicity, the configurations are reasonable approximation of those found on aircraft" NACA-TR-1317 - What is in work: Shadow Zones and Concentration Zones (to be published 10/24) https://icinganalysis.com/drafts/shadow-zones-and-concentration-zones.html Engine Inlets (to be published 10/26) https://icinganalysis.com/drafts/impingement-in-engine-inlets.html - Public Domain image of the week: https://icinganalysis.com/images%2FNACA-TN-4268%2FFigure%201.png #AltText: Figure 1 of NACA-TN-4268.
