NASA's Flight Dynamics Research Facility (FDRF) is a large, subsonic wind tunnel equipped with a vertical test section. This facility is dedicated to conducting flight dynamics research on atmospheric vehicles. Its primary research areas include stability, controllability, free-fall, aircraft spin, and spin recovery testing, supporting essential aerosciences evaluation and test capabilities.
The Flight Dynamics Research Facility (FDRF) at NASA serves as a large, subsonic wind tunnel. It features a vertical test section specifically designed for comprehensive flight dynamics research.
The facility's research encompasses several critical areas, including the stability, controllability, free-fall characteristics, and aircraft spin and spin recovery testing of various atmospheric vehicles.
The test section measures 20 feet in diameter by 24 feet high. It operates at speeds ranging from 0 to 172 feet per second (0 to 117 mph) with a dynamic pressure from 0 to 35 psf. The Reynolds Number ranges from 0 to 1.10×10^6 per foot.
Environmental conditions within the test section include atmospheric pressure and an actively cooled temperature of 79° F, utilizing air as the test gas. The overall facility stands 131 feet tall, supporting advanced flight research and aerosciences evaluations.
According to NASA Breaking News, these characteristics enable the FDRF to contribute significantly to aeronautical engineering and vehicle safety research.
