Hi,

DH.117 - Supersonic all-weather fighter project for F.155T

 

[Stargazer2006]

I have now a complete list of De Havilland designs from the Airco D.H.1 to the Hawker Siddeley H.S.147, except for two numbers:

• D.H.13 (which was apparently skipped by the company)
• D.H.138 (or maybe H.S.138) (which I have not managed to identify)

Any help on the latter would be MUCH appreciated!

 

[hesham]

Hi Stargazer,


after De Havilland absorbed by Hawker Siddeley group,the designation
D.H. was given instead off it,the H.S. designation.

 

[Stargazer2006]

I know that, but some projects were started under D.H. and therefore can be found under both names, such as the 121, 125, 136 and 146...

 

[hesham]

Hi Stargazer,


the DH-130 was the last De Havilland design,and for the DH-136 and DH-146,we
can say,formally we can say DH-136,but the official design is HS.136,that is for
example.

 

[hesham]

Hi,


DH-122 :was re-allocated to 6/11 seater executive transport project,
looks like DH Dove,powered by two turboprop engines.


DH-123 :was re-allocated to small executive aircraft based on
Vampire trainer,with six-seat capacity,later transfer to USA Jetcraft
Co. as MJ.11.

 

[Jos Heyman]

I have DH-122 as a competitor of the VC-10 and DH-123 as a twin engine high wing passenger aircraft, not unlike the Fokker F-27, that was abandoned in favour of the Avro 748.
I know Hesham says 're-allocated' in both instances but where does this information come from. How reliable is that reference source?

As far as the Jet Craft MJ-II (note the Roman numerals) is concerned, I found the following in Flight International 29 May 1969, page 892, reporting on the 1969 Paris Air Show: "Jet Craft Ltd Las Vegas (US 25, S) The stand displays models of the 17-seater twin GE CJ-610-6 MJ-III Mystery Jet commuter and corporate aircraft and Six-Seater R-R Viper 522-powered MJ-II jet—de Havilland Vampire T.55 derivatives. Jet Craft's MJ-T1 two-seater trainer (a Goblinpowered modification of the Vampire T.11 by Marshall of Cambridge (Engineering) is shown in the aircraft park and will be demonstrated." The page also has a picture of the mock-up of the MJ-III but I cannot duplicate that. Maybe somebody got better software.

I'm quite we have a topic on the Jet-Craft series somewhere but I can't find it using "Jet-Craft" in the search engine! I prefer not to post pics here (including the MJ-III mockup) because it would be off-topic... If someone could kindly point to the dedicated thread where the Jet-Craft series is discussed, we could have a link to it from here. Thanks.

 

[hesham]

My dears,


the source is the book, Stuck on the Drawing Board.

 

[Stargazer2006]

Perhaps we should rename it to "Jet-Craft Projects" or something like that.

Perhaps not, since the topic also mentions another bizjet derivative that had nothing to do with Jet-Craft.

A middle solution could be to rename it "Jet-Craft and other DH Vampire executive jet projects"...

done this way

Here is a DH document from my past (1958/9) that I have not seen posted. It covers many DH types up to DH 113.
