Power curves

Can someone give me a detailed and accurate explanation of the connection between the thrust curves vs drag and the power required/power available curves. I specifically want to understand what happens to the following when weight is reduced during a climb:
Rate of climb
Angle of climb
IAS and TAS.
All this is assuming non-turbocharged piston engined aircraft
Thx

shenebix,
That would take a lot of space to adequately explain. I suggest a book titled, "Aerodynamics for Naval Aviators" by H. H. Hurt. I don't know you're background, but this book explains things very well without all the mathematical derivation. Hope this helps. Take care.

shenebix,
The questions you have asked required a degree of explaination to answer. If you are genuinely interested in the subject, I would suggest looking at something like "Aircraft Flight" by Barnard and Philpott. Its a good elementary flight mechanics book, but covers a wide range of subjects in good detail. You should be able to get it from any big bookstore.
Hope this helps,

If you don't change the airspeed, CG/trim when you reduce weight, the problem reduces to a simple one as drag and power available are constant.
I.e there is the same amount of surplus power available to climb so the rate of climb is inversely proportional to the weight (work rate or power = mass * g * vertical speed) and the cosine of the climb gradient is proportional to the rate of climb at a given TAS.
