● HVAF is attached with small fins on the boss cap;HVAF mainly recovers the energy loss of propeller hub vortex in propeller downstream.
● The geometry shape of HVAF is very simple, and HVAF can be installed behind the propeller easily as original boss cap, which rotates together with the propeller.
● HVAF can save fuel consumption by 2%~5% as operating at the same speed.
● Rectify the strong downstream from propeller blade trailing edge and break up the hub vortex.
● Produce force
● Reduce propeller shaft torque by 2%~3% and increase thrust by over 1%~2%
