- Alright so I finished doing some calculations on the outlet guide vane parameters. As mentioned earlier, this final vane is designed to "de-swirl" the airflow of the air that's exiting the final stator. The whole purpose of the guide vane is to allow for maximum combustion of the fuel when it enters the combustion chamber, however since I'm not building one of those that doesn't apply. But, it has been shown that having a a straight flow of air increases the thrust produced, hence why jet engines have an outlet guide vane after the last row of turbines.
Anyways, here are my caluclations:
- Number of blades: 17
- ___Blade Angles___
- Inlet: 22.194
- Outlet: -45.249
- Incidence: -5.011
- Deviation: 45.249
- Camber: 67.4443
- Stagger: -16.538
In addition to those angles, like stated before, I also plan on doing a deviated blade, one that has a different angle of attack at around 1/3 of the length. This angle will be around 45 degrees.
So because of all these weird angles - if you can imagine a stage with an inlet angle of 22 and out of -45, I have to re-write my blade construction program. Also note, because this isn't considered a "working stage" it doesn't have the three stage variables:
I'll update this once I've re-written the program and have a 3D model to show you all.
Until next time.
