例句與造句

1. NOTE : The Tacoma Narrows actually failed due to Aeroelastic Flutter, not by resonance.
2. Vortex shedding was one of the causes proposed for the failure of the original aeroelastic flutter.
3. In many physics textbooks, the event is presented as an example of elementary forced aeroelastic flutter.
4. A tensioned but flexible belt vibrates by the passing flow of air, due to aeroelastic flutter.
5. Cause was found to be high-frequency, low-amplitude aeroelastic flutter of both the vertical and horizontal stabilizers.
6. It's difficult to find aeroelastic flutter in a sentence. 用aeroelastic flutter造句挺難的
7. The failure of the original Tacoma Narrows Bridge was originally attributed to excessive vibration due to vortex shedding, but was actually caused by aeroelastic flutter.
8. A " snag " was added to the wing's leading edge and stabilators to prevent an Aeroelastic flutter discovered in the F-15 stabilator.
9. The differences in air flows under these conditions led to problems in aircraft control, increased drag due to shock waves, and structural dangers due to aeroelastic flutter.
10. It is essentially an aeolian harp, except that it exploits the motion of the string produced by aeroelastic flutter to create a physical oscillation that can be converted to electricity.
11. Jones was convinced that hunting oscillation was an effect similar to the problem of aeroelastic flutter encountered in aerodynamics, and decided to hire someone from the aeronautics field to investigate it.
12. Its main span collapsed into the Tacoma Narrows four months later on November 7, 1940, at 11 : 00 a . m . ( Pacific time ) as a result of aeroelastic flutter caused by a wind.
13. In many undergraduate physics texts the event is presented as an example of elementary forced resonance, with the wind providing an external periodic frequency that matched the natural structural frequency, even though the real cause of the bridge's failure was aeroelastic flutter.
14. During development testing aeroelastic flutter was observed during a test that measured how the aircraft performed if its wing-to-strut join fitting fails at the same time the fuel tanks in the horizontal stabilizer were filled at over 15 % of their capacity.
15. On 27 April 1995 91-year-old aircraft designer, builder and significant figure in the homebuilt aircraft movement, Steve Wittman and his wife were killed when their Wittman O & O Special broke up in flight due to delamination and separation of the wing fabric, resulting in wing aeroelastic flutter.
