NASA Multirotor Test Bed 2
In mid-2022, a wind tunnel test of the Multirotor Test Bed (MTB) was carried out in the U.S. Army 7by 10-Foot Wind Tunnel at NASA Ames Research Center. This was the second wind tunnel test of the MTB, following the initial test entry that was conducted in 2019 shortly after the test stand was built. The first MTB wind tunnel test was essentially a shakedown test, exercising the different capabilities of the test stand. The second test entry was intended to be more tightly focused on a quadrotor configuration, with variations across multiple characteristics of the rotor system layout. These multirotor characteristics included rotor spacing, rotor azimuthal phasing, and incidence, in addition to more traditional variables like rotor rpm, vehicle pitch, and windspeed.

The data from MTB2 test campaign are included below. The test, model, post-processing, and more, are described in the MTB2 Data Report. The ReadMe file contains information on the parameters given in the data. There are also excel sheets of the Test Matrix sorted both chronologically and by configuration below.
