Turbine question
 
Does anyone know if turbine power can be calculated in HP's ? it doesn't makes much sense to me to rate it in just pounds or newtons of static thrust, without any reference of the speed or volume of fuel/air ejected.

Well, Turbine power as you call it, is actually a force, not power. It's measured in what is called static thrust as you had mentioned in your post. Thrust does not create any work if the object is not moving, and therefore you can't convert the two units. Plus there is another element involved when calculating work, and that is time. Work is a force applied over time.

But if you really want to see a relation between the two units, I guess this is the best I can give you is:

1 HP = 33,000 Foot Pounds / 1 Minute

As for volume of air and fuel.... it really has nothing to do with thrust directly, not for measuring it, or converting it to Horsepower, (which can't be done anyway)

Excellent reply, Neo. So, I cannot compare power levels from a propeller driven aircraft and a jet unless I know how fast the jet is flying under a period of time? (to simplify things out,
I am suggesting that both planes has the same Coefficient of drag and the same dynamic thrust at their maximum horizontal speed) .
