Seriously worse.
Edit to add: Whem you’re bored, take a read through, especially pages 166-168 to see the difference between UH-60, CH-53, CH-47 and V-22. Downward induced flow (aka rotor wash) is proportional to rotor system thrust / rotor area, in the case of the study, measured in psf (lbs/sq.ft) at their respective minimum and maximum all-up weights.
As a data set of representative rotorcraft, below is an extract of the report from worse to better:
MV-22: 10.7-22.3 psf (Min/Max AUW)
CH-53: 9.5-15.0 psf (Min/Max AUW)
UH-60: 8.2-9.2 psf (Min/Max AUW)
CH-47: 6.2-9.3 psf (Min/Max AUW)
So yes, the Chinook moves a lot of air…a lot, but that weight (mass) of air is spread over a very large area and wide slower moving blades than any of the other craft (including the Black Hawk, ironically).
