prop design
hello guys
I am looking for some information about turbo props like the saab 2000.
At the moment I am designing a prop for a model airplane where the tips are reaching mach 1 (re 200000)so I suspect some serious problems with shock waves and reduced effiency at the outer 25 % of the blade
I do have some information about the arad sections develloped in the 70's but cannot find any more recent information about profiles used on props for e.g. the saab 2000.
I would also like to know the mach number on the commuter airplane props like the saab 2000 or other ones, If you can give me the RPM,prop diameter,cruise speed and level I can do the calculation myselve.
If you know any sites of interrest or other sourses I would be very happy.
A 737 pilot with to many spare time
Thanx Robbert
