In this previous study, effects of circulation, thickness, and compressibility were retained, while the effects of shed vorticity and downwash
were not modeled.
Figure 17 indicates that there is minimal downwash
, with the bottom vortex spanning across the whole height of the base.
AIM 7-3-7, "WakeTurbulence," lays down some good words of warning: "In a slow hover taxi or stationary hover near the surface, helicopter main rotor(s) generate downwash
producing high velocity outwash vortices to a distance approximately three times the diameter of the rotor .
Dominator Platinum memory kits have a striking industrial design for good looks, patented DHX technology for cooler operation, user-swappable colored "light pipes" for customizable downwash
lighting, and Corsair Link compatibility for real-time temperature monitoring.
You start hovering over him, and he's being toasted in 600 degree [Fahrenheit] downwash
By observation of a downwash
velocity field in the presence of holes, the authors attributed the reduction in flow loss to the spiral flow with less vortex strength.
Her CHU was located adjacent to a MEDEVAC helicopter landing zone where rotor downwash
may have aerosolized soil particles that led to infection, although no other case reports were identified in her area of operations.
However, the Convertiplane was (optimistically) supposed to retain the low disc loading of a helicopter, in order to produce at the hover the moderate downwash
desirable for rescue operations.
THE dust raised by rotor downwash
in remote corners of the country has returned as political bigwigs hit the campaign trail for the biggest ever electoral battle, even as they shell out much more this time for reaching out to maximum number of voters in the shortest possible time.
This disconnect helps the follower dodge the substantial downwash
of air directly to the rear of a flying bird, Portugal and his colleagues report in the Jan.
There was also an incident in November 2011 where the Air Ambulance hospitalised a bystander when it blew wooden pallets into their legs with its downwash
The hook-up men--one maintainer determinedly gripping a 12-foot pendant while the other supported him--braced at the decks center for the incoming downwash
