rotor shaft การใช้

• The main rotor shaft was able to tilt slightly for forward control.
• The vibrations resulted when the rotor shafts were moved 17 degrees forward from vertical.
• Vertical-axis wind turbines ( or VAWTs ) have the main rotor shaft arranged vertically.
• The samples are pierced in the middle in order to allow the rotor shaft to pass.
• The Boeing Co . of Philadelphia won a $ 6 million contract from the Navy for aircraft rotor shaft drives.
• The rotor shaft eventually failed in flight, which in turn led to the aft blades and forward blades desynchronizing and colliding.
• The purpose of this experiment should be to examine the spectra due to misalignment between the motor and the rotor shafts.
• It was initially powered by a fan cooled Potez 9E nine cylinder radial engine mounted amidships, under the concentric rotor shafts.
• In reciprocating engines this is accomplished by turning the crankshaft ( Wankel Rotor Shaft ) which induces the cycles of intake, compression, combustion, and exhaust.
• Horizontal-axis wind turbines ( HAWT ) have the main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind.
• The non-rotating inner ring could be tilted and moved along the rotor shaft . The outer ring rotated with the rotor and adjusted blade angles via rods.
• While the horizontal reference datum can be anywhere the manufacturer chooses, most small training helicopters have the horizontal reference datum 100 inches forward of the main rotor shaft centerline.
• This refinement process is essential to meet the performance characteristics of parts like a helicopter rotor shaft, a flap actuator on a military jet or a bearing in a jet engine.
• Early operators discovered that if the APS5000 APU was shut down with the inlet door closed, heat continued to build up in the tail compartment and cause the rotor shaft to bow.
• The shaft on which the upper sheave is mounted drives both the main and tail rotors; the main gear box delivers power to the main rotor shaft through a set of splash-lubricated spiral bevel gears.
• The design of the transmission featured several unique and uncommon innovations for the time, such as single-part manufacturing of the rotor shaft and the anti-vibration measures integrated into the main gearbox and main rotor blades.
• VIM-VAR steels become bearings for jet engines, rotor shafts for military helicopters, flap actuators for fighter jets, gears in jet or helicopter transmissions, mounts or fasteners for jet engines, jet tail hooks and other demanding applications.
• This system is normally composed of two blades that meet just under a common flapping or teetering hinge at the rotor shaft . This allows the blades to flap together in opposite motions like a seesaw.
• A hallmark of Enstrom's helicopter designs from the outset has been the lack of exposed pitch change links for the main rotor, as the mechanisms are contained inside the hollow main rotor shaft, lowering aerodynamic drag.
• The Abeille's fixed main landing gear had two wheels on a single axle positioned a little behind the rotor shafts and mounted on broad, single struts to the mid-upper fuselage, together with a smaller nose wheel.
