I would like to know if creating a strong back pressure within a propeller duct will enable an aircraft to attain a higher altitude.
Please reference the conceptual drawing below.
This is showing a ducted propeller with the addition of a centrifugal blower/compressor. This hybrid propeller would consist of four parts sandwiched together and then welded in order to make one piece that rotates as one unit.
The purpose of the compressor is to create a strong back pressure within the duct which should enable the propeller to produce more thrust/lift and should enable the aircraft, particularly a helicopter or drone, to attain a higher-than-normal altitude. I believe that the merging of the airstream from the propellers with the airstream coming out of the compressor is what will create the strong back pressure throughout the duct.
I think one key application for this type of 'pressurized' ducted propeller would be high-altitude rescues such as rescuing stranded mountain climbers, or reaching an airliner that went down up in the mountains above the reach of most helicopters.
Will creating a strong back pressure within a ducted propeller enable an aircraft to attain a higher altitude?
