NASA and its international partners are using the same generically shaped wing design to create physical and digital research models to better understand how air moves around an aircraft during takeoff and landing.<\/p>\n

Various organizations are doing computer modeling with computational tools and conducting wind tunnel tests using the same High Lift Common Research Model (CRM-HL), a NASA-led effort.<\/p>\n

This ensures the aerospace community is getting accurate answers despite any differences in testing conditions or facilities.<\/p>\n

What started as a voluntary partnership in 2019 has grown into the CRM-HL ecosystem with 10 partners across five countries. The team is building eight wind tunnel models, which will be tested at eight wind tunnels during the next three years.<\/p>\n

\u201cWhat we are learning today would take us 10 years to do alone,\u201d said Melissa Rivers, subproject manager in NASA\u2019s Transformational Tools and Technologies<\/a> project, which leads the CRM-HL research. \u201cThe partners are using each other\u2019s research for the mutual benefit of all.\u201d<\/p>\n

The team will define and assess common wind tunnel conditions in more than 14 tests across the globe.<\/p>\n

\u201cThrough this research, we are learning about differences that occur when we build and test several identical airplane models in multiple wind tunnels,\u201d Rivers said.<\/p>\n

Researchers can use data from these wind tunnel tests to then check if the research tools using computational fluid dynamics are accurately predicting the physics of an aircraft.<\/p>\n

\u201cThe computer simulations and computational fluid dynamics tools are key contributions from this international partnership,\u201d said NASA\u2019s Mujeeb Malik, a lead researcher for the project. \u201cThe runs [tests] are critical to figuring out what we do not know and determining what we want to test.\u201d<\/p>\n

The partners are developing a standard way to communicate their data so that everyone can better compare the results from their models and wind tunnel tests.<\/p>\n

NASA also is developing a cloud-based solution to give each partner access to the data and foster collaboration.<\/p>\n

Expanding Collaborations with Common Research Models<\/strong><\/h3>\n

This high lift research effort builds on the success of a previous Common Research Model effort focused on transonic speeds.<\/a><\/p>\n

Between 2008 and 2014, many organizations built their own versions of NASA\u2019s model. They then tested the models in tunnels around the world.<\/p>\n

The transonic model helped the community better understand the physics of aircraft at cruise. The current high lift model focuses on the takeoff and landing portions of flight when the aircraft is flying slower than at cruise.<\/p>\n

Since there are more wind tunnels that can run low-speed tests, more partners can participate in the current collaboration.<\/p>\n

The partners working on the CRM-HL span five countries \u2013 United States, United Kingdom, France, Germany, and Japan and include:<\/p>\n
