Parnall Bodyless Monoplane Project

[hesham]

Hi,


in the magazine Air Enthusiast No.103,they spoke about Parnall Bodyless aircraft,
it seemed to be a twin engined aeroplane project,no more details,and they displayed
a drawing to M Voevodskii Bodyless monoplane,which Harold Bolas used it as the
basis for his projected to Parnall,has anyone addition info about it ?.

 

[Schneiderman]

This must be related to a number of patents held by Bolas in association with The International All-Steel Aircraft Syndicate, dating from 1921. Patent GB192431 describes the wing on this type of aircraft. It also mentions a patent for an aircraft that is numbered 19607/21, but I cannot find that one.

Great find Schneiderman.

 

[Schneiderman]

If we can find the other patent, 19607/21, we will probably see what the basic design looked like. The trouble is is that does not look like a patent number and searching on Bolas or International All-Steel Aircraft Syndicate doesn't locate a patent for an whole aircraft design.

EDIT.....found it, it was published as GB173206 in the name of International All-Steel Aircraft Syndicate only, no Bolas. The illustrations only show the side view, as in the other patent

 

[Schneiderman]

An earlier patent by International All-Steel Aircraft Syndicate was for this blended wing seaplane (GB170898). Bolas' later partnership with this syndicate suggests that his work on a bodyless monoplane was derived from this as well as Voevodskii's studies.

Wow,thank you Schneiderman.

And finally.......
Here is the original patent, US139135, by Voevodskii, or Woyevodsky as he chose to spell his name when he left Russia. This was applied for in 1919 and granted in 1921. We can see that the International All-Steel Aircraft Syndicate may have been a bit naughty as the similarities between the aircraft designs in both patents are many, too many to be a coincidence

EDIT. Woyevodsky's original patent was GB127684, applied for in 1918 and issued in 1919. The Syndicate's patent was applied for in 1920 and although this related to engine installation and later ones to structural features, the illustrations are clearly of Woyevodsky's design. However there is no indication that there was ever any connection between him and the Syndicate.
Voevodskii came to Britain in 1917, invited over by a representative of Airco who was visiting Russia. He simplified the spelling of his name when he arrived. His work was evaluated by the Aeronautical Research Committee in the wind tunnel in 1918 and the results issued as R&M 571 and 649 in 1919. They then decided to flight test some of his ideas and spec 6/21 was issued by the Air Ministry. A contract was awarded to Westland for the Dreadnought and presumably Bolas and Parnall had linked up with the Syndicate to submit an alternative project.
