(181) A fairing fitted over the hub of the propeller in some aircraft.

(182) Therefore , it is recommended to adopt the two - step change - speed propeller in the tug design.

(183) Abstract: The system of transforming data and generating process data of propeller was introduced.

(184) An on-line measurement system of screw propeller for for special Lathe-Mill NC Machine with Seven-Five Axis is developed.

(185) How to raise the propeller efficiency has been the key problem in airplane propeller design.

(186) Charcoal screw propeller is an important component of the device, the wear rate directly affects the salary bar for quality and yield.

(187) Period characteristics of radiated noise at high frequency is investigated by a method based on short time Fast Fourier Transformation,(Sentence dictionary) and propeller speed is estimated.

(188) Clutch Disc, Cover, Release Bearing, Clutch Parts, Flywheels, Propeller Shafts, Universal Joint, Clutch Woking Cylinder, Clutch Cables Shaft , Shaft Collars and Bright Bars.

(189) Water jet propulsion, widely used in the area of fast-speed ships nowadays, has increasingly taken the place of traditional propeller.

(190) When the power required by propeller is so high that the shaft speed cann't arrive a rated value, the tip of propeller can be cut to decrease its load.

(191) Can be used in ship industry, cold water treatment, sea water and cold oil, Low pressure valves, rotating equipment, and reciprocating pump hydraulic squeeze machine, the ship propeller equipments.

(192) The model is applicable to the reliability analysis and design of infinite life for propeller blades or other structural members with initial defects and accident damage.

(193) Sure that at least one propeller was moving in and out of phase.
