Hi,
I keep hearing about how the F-16 inlet is too small, turbulated, angled, etc., for the Dynamax fan to perform well in it, but it seems to me that someone needs to let the airplane know because in its ignorance of these facts, it seems to haul butt. Of course, a smooth inlet (free of hard transitions and such) is going to be better, but I don't see a performance deficit out n the field...
I have both (1991 productions) the Yellow and BVM in my shop. The BVM has aprox 1.3 sq. in more of intake opening over the Yellow and no protrusions at the main landing gear area.. Also the radius front of the BVM will minimize or avoid a boundary layer separation. However, the more I work on the BVM, the more I like the Yellow.
I will ultimately make a hybrid of the two models and take the better components from each on my next one.
I would have to agree with you. Dumb airplane just get pushed around the sky at blazing speed.
One issue I have with the Dynamax fan shroud is the way the fan shroud/housing is put inside the intake duct. I am making a ducting to have no angle change at this critical point of where the fan blades tips are nearly out of the air flow at high speeds. The duct will be on the inside of the fan and delivering air closer to 100% of the fan sweep area.
I have yet to see one fail, in any sense of the word. Unless it was before 1988.
