Schwingenflug Must be the Duetches Museum

I was in Germany last week and took time to visit my favorite museum the Duetches Museum in Munich. I was interested to find some information on Mr. Lawrence Hargrave, New South Wales aviation pioneer and inventor. Mr Hargrave was interested in ornithopters and flew many models. In 1892 one of them flew 82 meters. Here are some pictures of one of his steam powered mechanisms on display. More information on his models can be seen here

Also on display was an interesting full articulated rubber powered Buzzard model.

Khaled - Actually ancient Egyptian had a bird like object back several k's ago and the modern science placed that object under the wind turnnel tested. The result is the airfoil equal or better than todays modern planes. Perhaps your great great, grand father is one of them that had the opportunity visited a spaceship while back

Actually it has been suggested that the Egyptians had read about the KJELL effect to eliminate drag, suspend gravity, and produce a glider that never lands...... Unfortunately they ordered it from the Wizard from Wyoming, and they are still waiting for the tail to be built as evidence of the many photos.

Presented to the Engineering Association of New South Wales

The absence of any description of these twenty-five photographs might appear to be an oversight, but it is intentional as after long consideration I am convinced that a careful inspection of the plates can not fail to show the thoughtful mechanic the use of every part of the various machines.

By consigning the pictorial record of a portion of this work to your keeping experimenters will be saved much time and labour; and although some persons may now think it a waste of energy to make such structures, the time must surely soon come when numerous workers will devote their undivided attention to the development of some or all of the various types shown here.

An expressed demand for rapid locomotion is all that is necessary to bring into existance as diverse a variety of flying machines as we see in nature.

Sydney March 1899
So the australians where there many years ago thanks for sharing Larry .Mr Hargrave had a good vision .By the way Larry how are your Projects coming along regards Brian

Thank you for shearing Larry .Very interesting pictures.I like Mr.Hargrave's idea about steam powering of ornithopters /probably he didn't have many other choices/ and I think that one day we will return back to something like that most probably some variation of Stirling engine,which directly drive main spars .
The Buzzard is an model of Karl Herzog who has been an very successful artist painter as well which explain such a level of realism . His models are my favorites from the past. Here is bird's wing principle of operation demonstrator which is made from him specially for Deutsches Museum in Munich.You probably must have seen it:

The Bussard's wing is active twisted. See position E.

Seagull10,
I didn't miss the excellent gull model just couldn't fit all the photos. I definitely advise anyone who goes to Munich to stop and see this museum. LJ
