For questions about those devices that swing forwards and downwards from the leading edge of an aircraft's wings, allowing them to produce more lift without stalling. Questions about high-lift devices in general should use "high-lift-devices" instead.

Why didn't the Concorde have flaps or slats?

Why no slats? Slats are helpful for delaying flow separation to higher angles of attack and allow a wing to create more lift. … With Concorde B, a span increase and the addition of variable leading edge droop (no slats!) were proposed. …

What is this tiny slat for?

The wing-root fairing makes a small triangular segment necessary; outboard of it slats are used. The item 2 is a NACA inlet for cabin air, as commented by @mins. …

What effect do slats have on descent rate?

If the slats would increase L/D, they would not be retracted in cruise. … If thrust and speed are not changed, deploying slats will increase sink speed. …

Would adding a slat and a slotted flap increase the max CL of a multi element airfoil to 6.5?

Would that be several slats and flaps in sequence? …

How to calculate the lift coefficient of a multi element airfoil?

It depends. Are the c$_l$ values referenced to the local chord? Then you need to convert them to the chord of the full airfoil so they can be added. I wonder, however, how you can have individual lif …
