    It’s a very good display at the Fort. The pilot abandoned his aircraft as it was ‘vibrating’. Here’s the hole vacated by the blade.

    I also have a page on the late Jay Simpsons Thunderbolt P47 also on display in Fort Perch, but thats a different topic.

    David, KLM led the way with their investigations, as did Canada airlines, the UK did their own but later, after the Board of Enquiry. KLM’s results were quite definite. This is all explained in the following details on my munich pages:

    http://www.mikekemble.com/misc/munich.html and was authenticated by Capt Rayments son after reading it. also by Stanley Stewart, who wrote the book. Included in my pages are the full transcript of the radio converstations between aircraft and tower.

    apparently the Munich crash was caused by the drag coefficient (or something) of the deep slush was equal to the thrust of the props. Hence, no take off. The tests were conducted by KLM and airlines in Canada following the crash and they all came up with the same result.

    This was adopted by the worlds airlines in their training etc abut only the Germans refused to accept this, and still don’t because it places the blame on them and they still refuse to accept fault.

    One a similar topic, I have been finding out about a Spitfire that crashed in Birkenhead Park during WW2, the pilot bailed out and landed on the roof of a Maternity hospital in Liverpool allegedly.

    The cause of the crash, a prop became unattached. The remains were excavated in 2007 and are now on dispay in Fort Perch Rock, New Brighton. Thew whole room is filled with pieces of the plane.

    Attached is image of engine and prop boss from the plane.

    Isn’t it amazing how many real experts come out of the woodwork when things get technical. Love it.

    Actually, the information about diameter is more useful for me than the length of one blade because the rotation is still about the very center of the prop, so the distance from the center, i.e. the radius is what I needed. The blade itself, I assume, would be shorter than the radius of the circle defined by the rotation of the prop because the blade (again Iā€™m assuming) is attached to some sort of central shaft.

    I’m lost but this is what was said

    As stated, there are so many variants. I suggest we go for the most common, I think Rotal, which seems to be the most mentioned on some sites, the whole assembly measurements is given but not individual blades.

    This is part of the original question from a trigonometry teacher:

    Iā€™m using the Spitfire in a problem for my class as an example of angular speed and circular velocity, so I wanted the problem to be realistic. I found that the props rotated at about 800 rpm, but I still needed the length of the propeller to find the speed of a point on the tip of the propeller.
