Specific power curves
 

Hello everyone,

I am looking for help regarding the following issue:

Not a pilot myself (more of a theoretical field), I am currently working on a physical-matematical aspects of lift-drag relationship and try to develop lift-associated gas flow model for planes [during take-off and landing phases in particular];
What I am looking for is an actual, specific graphs (power curves: power available plotted on drag vs velocity axles) detailing basic aerodynamic characteristics; ones I most seek after are those of Airbus A380-800 and Boeing 747-400 - since they are the large 4-engine powered aircraft and hence will allow producing the most complex models.
Could anyone please point me in the right direction please? A link or source perhaps - is that possible?

Kind regards,
Jack

I think you would be better off placing this in the Tech Log.
