Hawker Siddley HS-129 and Handley Page HP.135

[Thorvic]

Hi

Whilst looking through some issues of Air Pictorial there was a picture that caught my eye in a Paris Special from 1965(? not too hand so not sure on the exact issue). The picture was a selection of European military Transport model, one was the Dornier Do28 another was a rather tasty swept composite wing Handley Page project HP135 in RAF transport command colours.
The other photo however was of the Hawker Siddley HS-129 which appeared to be a smaller brother of the HS-681 being a twin engined version with the slipper type VTOL engine pods associated with the VTOL 681.(photo to follow once i work out how).

Has anybody ever seen any details or references to the HS-129 before ?

Cheers

Sorry, no details for the moment, but another view to the model from Coplin's "VTOL Aircraft" (page 23).

 

[Thorvic]

Cheers for that

It certainly looks like the HS-681 little brother and if done a STOL without the VTOL would have made a rather tasty small military freighter.

Cheers

I'm more interested in the HP135!

475,000lb MTOW?


Wow?

HP135?

 

[hesham]

may be this aircraft was essentially De Havilland DH-129.

This drawing is unlabelled but appears to be DH/HS129

This 1965 proposal was for an ultra-long-range laminar flow transport. This four jet-engined aircraft would carry 200 passengers for 10,450 nautical miles, cruising at Mach 0.875. All-up weight 475,000 lb.

Not very good copy but haven't seen this pic before.

Is this an HS.129?

 

[Barrington Bond]

Yes.

Thank you indeed for sharing the brochure pics. Is the brochure yours? Have you more info from
it?

The artwork seems to show the transporter servicing a NATO marked P1154. It must have been done in the early 60s when the 1154 won the NATO competition.

This scene fits beautifully into the UK 75 RAF as an Andover replacement servicing the 1154 in its
UKMF support role (like the Jaguar).

A P.1154?? Wasn't that the Advanced Harrier?

 

[Mike Pryce]

I've seen the same brochure - it shows the P.1154 to NBMR.3 and DH.129 to NBMR.4.

The drawing is interesting because as Harrier (the expert on this plane) comments it is the
version of 1154 offered to the NATO competition in the early 60s.

The RAF intended to have this plane in service in the early 70s as the Harrier, but it was cancelled in 1964 by the Labour Government because of the desperate financial situation, and the RAF was allowed to order the 1127 (RAF) instead, starting off what we now know as the Harrier. So, 1154 was actually the original Harrier.

The DH 129 and its German equivalents (Dornier 131 and later 231) were intended to support aircraft in the field in Germany or on the NATO flanks.

The brochure is at the National Aerospace Library, Farnborough (a recent donation). It's not that large about landscape A5 and those were the only pages I was allowed to have copied due to copyright rules they were enforcing. However quite a few I think appeared in the likes of Flight. There was one cutaway in it I hadn't seen but it was rather tiny in size so I didn't bother with that and also the cover was a colour painting (silver and blue paint scheme with NATO markings I think) but didn't look as good as the interior b/w's.

Thank you for taking so much trouble and giving us all easy access to this material.

The 129 is very much a vstol Andover and would have fitted into the proposed mobile
UK force structure for the late 60s: TSR 2s for long range strike 1154 Harriers for Close
Support HS 681 for Intra Theatre lift The 129 would have enabled the 681s to do without
the expensive vstol pods. Apparently "Project Prodigal" was going to give the Army the
same sort of hyper modern kit for this force: ultra light tank destroyers, jumping jeeps and
the Scorpion CVR() family. Sadly only the latter became reality.

We now know that all these systems were too complicated and had serious flaws. But the excitement of the possibilities in the early 60s is hard to shake off and are the stuff of What-if!

Forgot this one..

The DH 129 and its German equivalents (Dornier 131 and later 231) were intended to support aircraft in the field in Germany or on the NATO flanks.

I think its a great pity that NATO could not work more uniformly on such a warranted project, instead of competing in an individual nationalistic-type competition, which would have delivered a workable and operational aircraft of this type and requirement!!
The Hawker Siddeley H.S.129 & Dornier Do 131 looks so similar in design and concept!

Hi,
