    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    This is exactly the kind of info I'm looking for, thanks for sharing the link.

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    You mean to tell me Aluminum expands at twice the rate of steel irrespective of what alloy or composition or silicon content there is? And as for the Orenda 600, I don't see how you can compare an automotive engine that was converted for aviation use vs a purpose designed aircraft piston engine...

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    A manual compression release for the lower cylinders can be incorporated into the heads where the oil is evacuated from the combustion chamber and collects in the rocker cover. If the compression release and spark plug are oriented wisely within the compression chamber, all the oil would drain...

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    While they are big and draggy, the effects are more pronounced the faster you fly which thankfully for a bush plane is less of an issue. All the issues that you mentioned are rectified easily with modern manufacturing techniques and processes.

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    I agree with all that you said but that's assuming high usage like commercial aviation. For someone who flies twice or even thrice a week for about 4 hours per flight session, it just doesn't make economic sense. For commercial aviation, cost of capital acquisition is very high, which demands...

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    Pretty sure a mortgage and then some! I am a little baffled that radial engine manufacturers are pretty much extinct at this point which is a tragedy. A turbine can never achieve the fuel efficiency and ease of maintenance that a radial does, assuming one is familiar with their very picky...

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    Hahaha! I was Santa Monica airport last week and found it very hard to believe that they were actually manufacturing aircrafts there and not some small GA aircraft but DC 3's! Hahahahaha, I completely understand by the "marine layer". It looks like someone pulled a blanket over Santa Monica. I...

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    I'm in West LA, pretty close to Santa Monica airport. As for the reason why I'm looking for plans, it's for a stress and deformation study of the wing structure. I'm interested in the design of bush planes, and trying to gain a deeper insight of how the original designers went about their design...

    Plans for De Havilland Beaver, Nooduyn Norseman or similar

    Howdy folks, Has anyone scratch built a Beaver or any other aircraft of a similar size and importantly role? I looked into the Murphy Moose but it's only available as a kit. I came across the St-Just Cyclone which is a replica of the Cessna 180 / 185 and was wondering if someone has done a...

    R 4360 Wasp Major

    Howdy folks, I am trying to find out how the crankcase came apart for a wasp major. The crankshaft was a one piece forging and the throws wouldn't clear the main bearing bores. So it looks like the crankcase came apart radially like the petals of a flower and I am trying to find any pics or...

    Steel aircraft spar

    Thanks a ton for the replies, the Stinson is pretty unique with its welded steel tube wing structure. What about fighter jets? What are the Migs made out of?

    Steel aircraft spar

    Hey guys, I am trying to find out if there have been aircrafts that used steel spars & so far it looks like the "Thrush" line of cropdusters are the only ones. Are there others out there? Any pictures of the spars? Is the construction similar to an aluminum wing (laminated angles and...

    Martin Baker MB series aircraft construction

    Thanks for the links Cheapracer & Matt, I already have those pictures. Apparently the main wing spar is supposedly made from built up steel laminations that taper towards the wing tip but they look like regular aluminum extrusions. I don't know if they used steel strips riveted together like on...

    Martin Baker MB series aircraft construction

    I have been scouring the internet for pictures of the MB series of aircrafts manufactured by Martin Baker. Does anyone happen to have pictures of the airframe, spars to be specific and the specially designed joints they used to connect the steel tubes. Also would anyone happen to have the patent...

    Steel tube aircraft wing

    Have there ever been any homebuilts that were constructed in this manner from either steel or aluminum?

    Steel tube aircraft wing

    Hello everyone, I happened to look at the wing structure of a Stinson Reliant and am curious as to how they were manufactured? The structure looked to be built out of welded steel tubing and are the ribs steel too? Are there any other aircrafts that were built in this manner and how did they...

    Radial engine oil consumption

    Is the oil consumption on a radial engine high only because of poor scavenging from the crankcase? Have they been completely phased out or are there new designs being developed?
