What type of engineering considerations (corrosion prevention, electrical conductivity,...(?) ) needs to be made when approving particular painting materials, e.g. paint stripper, filler, primer, topcoat, etc.
1) Story going around of a private owner who used automotive wax for buffing his a/c...
How come the propeller arc is behind the pilot in high wing twins (MU-2, Partnavia, Aerocommander) and in front of the pilot in low wing twins (Cessnas and Pipers).

Hello all,
I have a specially made bolt/stud that requires remanufacture. A materials analysis of the bolt indicates that the threads have been rolled. A quick search on the internet indicates that rolled threads offer 30%-70% improvement in fatigue stress or a ten-fold increase in service...
Hello all,
Consider a crack in the middle of large sheet of metal, about the same dimensions as, say, the sidewalls of the engine bay mount for the Cessna 210. The crack was probably initiated by a tool scratch, falling screw driver, whatever. There is now a crack that runs at approximately...
As standard practise, we specify the cad-plate of all steel parts we design to QQ-P-416F. However, it has come to our attention that this may dramatically reduce the fatigue life.
On page 287 of "Mechanical Engineering Design" by Shigley and Mischke it states "Metallic coatings...
This question is a bit off engineering, but maybe interesting none the less.
The Beechcraft Baron has an "aft cabin door ajar" warning light. Where do you think that this should appear in the ATA code?
a) 52 : Doors
b) 33 : Lighting
c) 31 : Indicating and recording systems
Have fun...
Hello,
Does anyone know how to derive the pressure distribution of a body of revolution given the geometric section properties. Kind of have the feeling that it is equivalent to the 2-D flow pressure distribution, if the thicknesses were sqrt'ed.

Hi. Anyone know any reports or had any experience with Vee-tail flutter characteristics. I'd imagine that it's be worse since the ruddervators can not have a torsionally stiff connection, which has been a requirement for elevators since the 1920's.

Howdy all,
Well since diffusers didn't grab your attentin, how about this?
How should you design the exhaust stack for a turboprop to maximise cruise efficiency? Specifically PT6. Manufacturers installation manual appears somewhat inadequate. The results from their CCD program gives a...
Hello,
I am looking for engineering information on inlet diffuser design. Specifically, angle versus length data for stable flow and maximum pressure rise and minimum drag and energy losses.
