Hello scientific world!
I'm working on nozzle optimizing for aircraft jet engines, especially turbofan engines. I need to the engine nozzle geometry of an aircraft plus a parameter distribution such as pressure/Mach to validate my calculation. Thinking to get such information from famous manufacturers such as Cessna, Golfstream, Bombardier, Boeing, AirBus and or etc. but doubt to get any help from them. Is it possible? What's your idea to figure out such issue?
Dear Roh,
First of all, you should contact not aircraftmanufacturers but aircraft engine manufacturers like General Motors, Rolls Royce, Pratt and Whitney, etc. On the other hand, I do not think they provide you with that info, since most likely it will be confidential. Anyway, you may find many CAD files of aircraft online, like the one for the A320 that I am sending you via a private message.

I'm much obliged beause of your favor, downloaded it but from where this scaled-up file has came?
I've seen many websites full of CAD files but the point is that the geometry should have been sketched based on the real one.
More probably you're right about the manufacturers but everything I need should not be classified. I just need the real geometry (doesn't matter if it scaled-down) of an engine nozzle and a parameter distribution to validate my investigation.
As I've asked previously here:
https://www.researchgate.net/post/Need_experimental_measurement_of_a_turbofan_engine_to_use_for_validation
There are some reports on the net although there are some unclear points bout them. Undefined geometry based on cartesian coordinate, unclear parameters distribution, ... are some instances of the problems that plagued me. The main problem is that I'm not working in a company which make aircraft or maintenance them. If I were a staff in such manufacturers or maintenance companies, I could draw the geometry using a measuring tape easily and I think I could get some pressure or tempreture distribution(points) using sensors or the computer of the aircraft. Maybe a pilot could help me!?
I would appreciate any idea!
Dear/Roh Dargahi
Referring to your question about data for validation related to geometry or any properties (pressure, Mach number,......) You should share one or two researchers from air craft company working with you in order to provide you with most of hidden measurements and some references related to your work.
