Edgar Percival Jet designs

[robunos]

I came across an article in the september 1984 edition
of 'Aeroplane Monthly', about Edgar Percival, who had died
earlier that year. In the article I found this :-


"In 1962 he [Edgar Percival] designed the Percival Gull Jet, a 12-place jet-engined executive aircraft with a cruising speed of 565 m.p.h. The Percival STOL Jet followed in 1968 and the Gull Twelve, a twin turbine-engined general purpose STOL aircraft, in 1970."
Does anyone have anything more on these designs?
There was also an image of the Percival Gull Jet, see below.


cheers,
Robin.

Cool pic. The Percival design number that could correspond to the Gull Jet is the Model 117, described as an "Orpheus-powered executive transport" but of course this needs confirmation.

A strange document pertaining to the Gull Twelve is mentioned on the NMA (National Museum Australia) website... Could the customer have been a Nigerian president or something like that???

They also have a file on the Gull Ten project, a multi-purpose STOL aircraft which seems to correspond to your 1968 model:

They seem to have received Mr. Percival's own private collection, in fact:

Can any Aussie forum member have access to these and let us know a little more?

Thanks, Star, those documents look really fascinating...
I also see a reference to an 'EP.10', which seems to be a
twin-engined light plane....


cheers,
Robin.

I noted that 'EP 10-J' designation too. Why the suffix, I wondered? Is this a twin jet light plane?

Unless the "J" stands for the customer, which leaves only Jordan as a likely (?) candidate...

This the aircraft I saw as the 'E.P.10'.
The link to it is below :-

The second image below is my amateurish effort to improve
the original...

Amateurish?? I think you did GREAT!!

 

[Stargazer]

In fact, thanks to your "amateurish effort", I was able to produce (in some even more amateurish fashion...) a clean profile view of the E.P.10.
I tried to correct the view a bit, since the original photo was slanted and the right page a little narrow compared to the left one... Yet I can't guarantee 100% accuracy here. It's more of a working image to start from than a definitive blueprint!

 

[robunos]

Thanks, Star......
Right, speculation time, any ideas on size, number of passengers, etc.?
I'm thinking equivalent to the Beagle 206, or maybe a little larger,
two more passengers, maybe, perhaps pressurised?


cheers,
Robin.

Hi,

can I ask if this designer had early series from EP.1 to EP.8 ?,of course we know EP.9.

From Aviation magazine,

was that the answer,why Mr, Percival began with number "9" ?.

 

[Hood]

Edgar Percival was a known user of 'boosted' type numbers and construction numbers, he used the same trick at Percival Aircraft so his customers would think he had designed and built more aircraft than was the case!
Perci
To be fair though, he did design several aircraft following his departure from Percival Aircraft, so 1-8 were probably his post-Percival studies

Note that the E.P.9 was originally P.9 but was changed to avoid confusion with the earlier Q.6 variant project.

Hi,

Collection Explorer

I'm not sure if you are interested. Edgar was my uncle. As stated previously most of his memorabilia is in the NMA in Canberra. I have all the papers that his brother deemed too personal or irrelevant for the Museum. I would be happy to share this information now. Are any of you enthusiasts in Australia? There are technical papers and photos of a prototype model of a jet.
I was with him in England in 1969 and he had certainly been to Africa( I always believed it was to a meeting with Gadaffi) and to China (where he met Madame Mao and some other members of the Gang of Four) . No written proof of any of this btw.

all of this stuff.

[TsrJoe]

Very interesting Indeed, many thanks for posting, are there any drawings of Percival's Gull Ten design (EP.10?)

cheers, Joe
