Hi all, I am currently designing a fixed oxygen system for a 4 place single. Typical system with 40 cu ft, charge on bottle at the baggage comp., discharge panel, flow fuse, warning light and mechanical gauge. I have yet to argue with the Feds for not having a system (typically cable or...

Thanks for your responses guys. I am not redirecting the flow away from the cowling fins, but rather preventing it from escaping to the lower compartment (bottom cowling area). The fuel flow requirements are set properly per our flight tests. I did manage to design a bracket that I will support...

Design/certification Considerations in Composite Aircraft Structure Joseph R. Soderquist National Resource Specialist, AIR-103

We are testing a turbo normalized system on a TCM IO-550 engine. At 25,000 FT, the converted CHT and OIL Temps. per FAR 23 are above the redline. We have enlarged the inlet and cowl flap areas and it did improve the temps., but did not lower them to a desirable value. Instead of re-enlarging the...

What is a bellmouth?

Just to add to this, the primary purpose of winglets is reducing the 3D effects of a finite wings (downwsh).

Agreed, thanks to all for the answers.

Thank you pardal, could you please explain what you meant by "water could be hard".?

I appoligize if this sounds a little immature or off topic, but can someone identify some of the very basic pros and cons of cooling air using above method over using intercoolers (air instead of waters)?

Pictures and details would certainly help. Let me know when you have them posted or can email them. Interesting project.

I agree with I278 about the aesthetics of sweeping the tail. However, I strongly disagree that tapering wings are "just for looks". Wing tapering have a huge impact on the core aerodynamics, especially on the 3D effects and mean aerodynamic chord. I wont go as far as saying tapering is...

Generally, I don't think control cables fatigue or creep. If any cable will creep, it will most like be engine control cables running close to the exhaust system. The maintenance manual calls out lubricating the cable when the input required exceeds a certain amount. My experience tells me that...

I think it highly depends on the amount of lift provided by each surface. I think the above answer should be a good place to start (Stability Equations).
