There can be significant propeller noise and vibration reductions with a propeller synchrophaser.
2.
A traditionally located vertical tail would have transmitted propeller noise into the airframe.
3.
It was thought this might reduce propeller noise.
4.
At about 0100 on 24 June 1944, Fish reported hearing some faint propeller noise in the area.
5.
Now scenes of the accident fill his office, taken by a TV helicopter whose propeller noise vibrates through Sippial's trailer.
6.
They also don't react to propeller noise, possibly because the noise projects behind the ship or because the whales have genetically inferior hearing.
7.
While on the HSUL staff before making the move to Penn State, Ross first learned about propeller cavitation, the main source of propeller noise.
8.
Dr . Kramer had a wide range of interests and his work encompassed automobiles, gliders, propeller noise, acoustic missile and wake tracking, and underwater coatings.
9.
The more powerful engine did not increase the maximum takeoff weight but allowed operations at higher altitudes, and its lower output speed helped reduce propeller noise.
10.
The constant speed propeller and reduction gear result in a propeller tip speed that is 10-15 % lower than comparable conventional avgas engines, reducing propeller noise.
