Isokinetic Probe Total Water Content Measurements in the NASA Icing Research Tunnel with Supercooled Large Drop Conditions
Autor: John W. Strapp, Lyle Lilie, Thomas P. Ratvasky
Publikováno v: AIAA AVIATION 2021 FORUM.
An Isokinetic Total Water Content Evaporator (IKP2) was used to measure liquid water content (LWC) in the NASA Icing Research Tunnel (IRT) with spray conditions that ranged in LWC and cloud drop size spectra as characterized by the median volumetric

Publikováno v: AIAA AVIATION 2021 FORUM.
A collaborative effort to better understand cloud characterization probes in Supercooled Large Drop (SLD) conditions, as well the ability to simulate these conditions in several icing wind tunnels, was undertaken by NASA, NRCC, CIRA, ECCC, FAA and Me

Ice Crystal Sizes in High Ice Water Content Clouds. Part I: On the Computation of Median Mass Diameter from In Situ Measurements
Autor: Emmanuel Fontaine, John W. Strapp, Delphine Leroy, Alfons Schwarzenboeck
Publikováno v: Journal of Atmospheric and Oceanic Technology. 33:2461-2476
Engine and air data probe manufacturers, as well as aviation agencies, are interested in better characterization of high ice water content (HIWC) areas close to thunderstorms, since HIWC conditions are suspected to cause in-service engine power loss

High ice water content at low radar reflectivity near deep convection – Part 1: Consistency of in situ and remote-sensing observations with stratiform rain column simulations
Autor: Fabien Dezitter, Andrew S. Ackerman, John W. Strapp, Alexei Korolev, Christopher R. Williams, M. Weber, A. Grandin, Ann M. Fridlind
Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 20, Pp 11713-11728 (2015)
Occurrences of jet engine power loss and damage have been associated with flight through fully glaciated deep convection at −10 to −50 °C. Power loss events commonly occur during flight through radar reflectivity (Ze) less than 20–30 dBZ and n
