Sourcing landing drag coefficients

[merlin505]

I'm doing some academic research on aircraft landing roll distances at the moment.

Does anyone know where i can reference drag coefficient values at touchdown attitude and speed for airbus and/or boeing aircraft? Have tried "Janes" and "Jenkinson- civil jet aircraft design" with no luck.

Either:-

(1) Company aerodynamics department, or

(2) Estimate using ESDU data sheets.

Hi Genghis,

Thanks for the suggestions. ESDU sounds like the most immediate solution.
