Jet Provost 5x Aerodynamics
On the 'Wingtip-tankless' version of the JP5 (and possibly others) there is a roughened skim (concrete) on the outboard leading edge of each wing. Long ago as it is now since I flew the JP, I have generated some heated discussion amongst colleagues as to the REAL reason for this (presumably) aerodynamic tech-fix.
Does anybody remember the reason it is fitted or better still can they refer me to any RAF Doc that authenticates the reason?
Thanks

I tthink you will find that it was to generate more energy in the boundary layer for better aileron effectiveness. The JP3 with tip tanks always had a better more snappy rate of roll than the 5A. Never flew the 5B with the tanks. Anybody have comments on tthat particular variant?
