Hi folks,

Here are a couple of civilian VTOL concepts from Hawker Siddley.

First the nice little HS.140 business jet:


Then the larger HS.141 commuter airliner:


Don't have much information on them I'm afraid.

Regards,

Greg

Hi GTX

It´s difficult to see the HS.140 cut in two parts, maybe if you reduce the image help us to visualize completely.

Gracias, sorry for my english

If you look in the book "Stuck on the Drawing Board", there's a prior design incarnation of the HS.141 that had a ogival delta wing and twin fins. Very futuristic looking and in some ways better looking than the final HS.141 iteration.

Hi,

the Hawker Siddeley Aviation Ltd. created that
new concept for VTOL light aircraft.

Hi,

a great VTOL aircraft designed by L. Chinchester-Miles
for Hawker in 1972.

Ah, the HS.140 fan-lift communications aircraft, a really nice aircraft !
There was an issue of Scott's APR featuring this type, I think ...
A 3-view can be found in "Stuck On The Drawing Board".

Some photos from the Midland Air Museum. If you're interested in British projects, this museum is a must see.

AWACS?! :D

Looks like a diagram dealing with air circulation to me?

"Latest Civilian V/STOL Aircraft Projects of Hawker Siddeley Aviation, Continuation from FR6/71" by TK Szlenkier, English translation of Flug Review International July 1971, NASA Technical Report, November 1, 1972.

The latest civilian V/STOL aircraft are examined. It is found that such aircraft are more economical and convenient in short air flights, require lower capital investments compared with other systems, and have less influence on the environment.

The Hs 140 and 141 were schemed in the 'Research & Future Projects Dept' at Hatfield headed by Derek Brown. The model with the ogival wing was the HS 133 I believe. I don't remember the twin fins but a powered wind tunnel model existed using small Dowty fans (about 3").

Charles Bradbury's HS 140 was schemed by David Kent. The wind tunnel model used the same 6" fan that was used in the HS 141 model (x16). David Kent later worked on Ian C-Miles' business jet ('Leopard' I think) post HS.

The large scale HS 141 wind tunnel model was developed by John Holmes-Walker who ran the powerplant group within the office. Major parts of the model were manufactured at HS Brough in the model shop. If you are interested, more later.

As mentioned in Teddy Szlenkier's paper on V/STOL research, several test rigs were used for HS 141 research. Initially, a thrust deflection rig was used to identify nozzle shapes and develop suitable thrust deflectors. A 12" (30cm) fan was developed for noise research and larger scale flow research and a 6" fan was obtained to assess its suitability for the large scale HS 141 wind tunnel model. Other test rigs were run but I am only aware of them and have no details.

The 12" fans were developed by David Budworth Engineering of Harwich. The HS project engineer responsible was Robin Boning. Budworth was absorbed into Noel Penny Turbines which is now defunct. To get some 'real' information on the effects of lift fans it was proposed to use a modified Folland Gnat with the fans mounted at the wing root trailing edge as in the HS 147 STOL scheme. These were to be tip turbine driven Budworth type fans powered by pod mounted gas generators on the wing. Considerable design work was done on this but it did not get the go ahead.

Here is a three variants for Hawker HS.141;

first HS.141-16 with 16 lift fans.
second HS.141-12 with 12 lift fans.
third HS.141-8 with 8 lift fans and two rear mounted engines.

I don't think the photos are of the Hatfield 15 ft. tunnel. If not Hatfield it is likely to be the NRCC tunnel in Ottawa, Canada.

Could someone help me with the little HS 140 bus jet? I have the cutaway from this thread and also the line drawings from the patent but cannot find the dimensions anywhere. Could anyone with the Reference Book on British civil projects (I cannot find my copy) post them.

I am thinking of adding to my collection of what-if models with a model of the HS-140 in RAF Air Support Command colours as a Beagle Basset replacement.

Good success for your model ! ;)

Thanks for this info. I will have to find my copy!

I will post pics of my model, if it gets made, on the Models thread next year (they take 6 months to make in the Philippines). I have a VC 10 Superb (BOAC), an HS 141 (BEA Union Flag) and an HS 134 (BEA Red Square) being made for me from Aviation Retail Direct in Hillingdon. I might post on the models thread when they are done though the moderators dont seem to to like "own fictional" models.
