Xinhua Chengdu, November 17 (by Hu Xing rain blue red) assembly in Sichuan by 5 meters of a vertical wind tunnel test bed helicopter 16 vertically developed to fill the Chinese helicopter wind tunnel test blank vertical drop, with a commitment to helicopter flight performance models of the vertical test of the ability.
helicopter vertical lift helicopter pilot technology is indispensable for independent research and technology of wind tunnel tests. The two meters by four meters and test equipment are the level of helicopter rotor wind tunnel facilities design, difficult to simulate the vertical rotor flight. And 5 m for the establishment of complete vertical wind tunnel tests of helicopter vertical lift technology, which was launched in 2008 in this test-bed research project. Group using the 2 m rotor model to guide the completion of the test, the rotor shaft speed to 2100 rev/min. Vertically through the state simulation model rotor, rotor flow visualization, etc., to solve the vibration test stand, attitude angle accurately control and other issues. Leading results showed that: run a reliable test bed, to achieve the desired specifications.
It is reported that the test bed used primarily for the vertical lift rotor driving force model test, able to take a helicopter model developed in the performance test and the machine vertically and rational research trials.(edit: SN049) share:
