Of all the lift devices the Krueger flap is in my opinion the oddest
one. Its hinged at the front and pivots forward into 'lift' position.
Stick out your hand, palm down, fingers folded back flat. Now
straighten your hand so that your fingers are bent down about 30
degrees from the plane of your palm. You have imitated a Kruger flap.
FWIW the L1011 had a neat mode of spoiler operation - with the
trailing edge flaps in land (33 degrees) position the wing spoilers
were positioned up 8 degrees. Slight movement of the yoke fore or aft
from the trimmed position raised or lowered the spoilers effecting a
useful change in lift with minimal change in AOA. Made it very easy to
stay on a glideslope or maintain a set rate of descent.

The L-1011 lives on as a launch platform and offers performance superior in
both rate of climb and payload, over the B-52.
