THRUST CALCULATOR
The thrust calculator can estimate the thrust of an airplane, there are
many variances and some known factors.
Lets assume we have an airplane and this is its first flight. We know the
size of the propeller and we can do a static full throttle rpm check with a
tachometer on the ground. We can now add these known figures into
Thrust Calculator. By the fact that you can verify thrust it becomes
possible, to estimate the general power of the airplane in advance.
This will give you more knowledge about your plane and the power
characteristics to make your first flight less challenging and safe, after
all you may have other flight characteristics to deal with. This should
help you to estimate flight take off distances, recovery from a stall. For
more experienced pilots this will enable them to calculate if the plane is
going to be able to hover. It can show you what changes to the power
calculation will be affected by a different size propeller.
