Gas turbine blades Dimentions and Design of aircraft engine

AI Thread Summary
Gas turbine blade design for aircraft engines involves critical considerations of dimensions and blade count attached to the rotor disc. For initial design work, using a NACA airfoil profile and extruding it to a reasonable length is recommended. Conducting a cyclic analysis with a dummy shroud can help assess fatigue and creep failure. Specific dimensions and speeds will vary based on design requirements and engine specifications. Engaging in tutorials and testing can provide valuable insights into the design process.

Hi

I am working on gas turbine design to investigate fatigue and creep failure and i want to design gas turbine blades for aircraft engine. I need to find out the dimention for CAd design
if anyone help me that what should be the dimention of these blades and how many blades attached to roter disc. i also want to find out speed of these baldes means some calculation is well

cheers
Mac

Chances are no one is going to give you a blade profile. If you're just doing tutorials/testing, then just grab a NACA profile and extrude it up a distance that you think is reasonable. Then, model up a dummy shroud and do a cyclic analysis.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
