RE: New test and tune bench for Nano turbines from www.HAB.se
the rotors of the p20 are just a little to small for high trust
you can say that the p20 is a basic engine
the compressor is 36mm , but has only 10 blades,and to small intake
also the tipheight of the compressor is very little so thats why the engine does not produce more then 2,4 kg
i tuned many p20 engines ,and i can get them to 3kg
the kolibri t25 , has larger compressor blades,and more tipheight
also the turbine blades ar longer ,and instead of 21 blades , he has 25 blades, more power
and thats why the t25 can reach the 2,8 ,almost 2,9 kg
its simple ,if you understand turbines
also my jetjoe junior produce 2,6 kg now
only change is compressor wheel
