NASA is developing tiltrotors and is currently installing a place to test them, the U.S. government organization said. Named the Tiltrotor Test Rig, or TTR, the apparatus is due for testing in February at NASA’s Ames Research Center in Silicon Valley, California.
The test rig is a large tilting mechanism on which NASA can attach rotor blades. It can then be put in a wind tunnel for testing. Since the rig is so large, and the rotor blades add to the overall size, the first test is set to take place at the National Full-Scale Aerodynamics Complex (NFAC), which NASA touts as the biggest wind tunnel in the world. When fully functional, the test rig should be able to support rotors up to 26 ft in diameter, capable of reaching 345 mph.
During the first test, the main goal is to give the rig a try. It will be the first time the system will be completely assembled and operated. Any anomalies spotted will be noted. Should the rig pass all testing, it is expected to participate in general aerodynamics research.
