NTF Test Data
The 2018 CRM‑NLF semispan test at NASA’s NTF evaluated laminar flow across Reynolds and Mach ranges, advancing cryogenic TSP transition‑visualization methods. The post NTF Test Data appeared first on NASA Science .
NASA completed a test in October 2018 using the new Common Research Model (CRM-NLF) wing in the National Transonic Facility (NTF). The primary objective was to assess the extent of laminar flow on the CRM-NLF wing under various Reynolds numbers and test conditions. This test acquired data at chord Reynolds numbers ranging from 10 to 30 million and Mach numbers between 0.84 and 0.86.
The investigation provided significant insights into the procedures needed for laminar flow testing in the NTF and advanced the new carbon-based heating layer technique to improve transition visualization data from temperature-sensitive paint (TSP) in a cryogenic wind tunnel.
