The emergency procedure is titled "Propeller Pump
Light(s) --Steady," which is an area of debate in the community when it comes to only a flickering light.
We had to do the one that applied to the 602's propeller pump
In 2000 the intra aortic propeller pump
, a new device designed to continuously reduce after load, was developed (8).
Example performance curves for a large propeller pump
are shown in Figure 19-7.
The gear drive connects to a Lo-Lift single-stage, propeller pump
with a capacity of 50,000 gpm.
So, there I was (I had to say that, don't judge me), as we received indications of a loss of pressure from our main propeller pump
on our port side.
When the engine panels were removed, a steadily increasing leak from the propeller pump
housing was found.
Initial adjustments were in work when a bolt was found wedged between the propeller pump
housing and the reduction gearbox (RGB).
For general utility applications, the vertical-shaft modified propeller pump
is the most useful.
The first indication of a problem was a slight aroma of smoke in the cockpit, followed immediately by the illumination of the master-caution light, two propeller pump
lights, and an RPM overspeed of 105 precent on the starboard side.
