The attached photo posted on an Italian Falco site http:www.aldini.it shows a modification of a drooped leading edge to Rib 14 (tip rib).
The Sequoia Falco website which also posts the identical photograph, states that the early models of the SF-260 stalled at over 100 mph, so the modification of a drooped leading edge was made to improve stall characteristics and also to enhance aerobatic behaviour.
Two questions (Orion, where are you?):
1. The SF-260 is more or less a stretched Falco with a larger engine, and obviously heavier and faster. Other than construction material - the Falco is wood, the SF-260 is metal, they are quite similar, sharing the same wing and tail surfaces with minor differences. Is the referenced increase in stall speed due entirely to the increased weight and speed?
2. How is this drooped leading edge designed/calculated? My initial impression is that it functions similar to a leading edge slat. Is this correct?
Thanks,
Alex
