Interesting. Is there a good reference for the development and ultimately cancellation of the P.1154?

Am i reading this correctly? The 2 engines have combined rotating nozzles? :eek:
Must be pretty lossy...


This must rank very high among aerospace oddities. Thanks a lot for posting.

They are 'handed' nozzles. One engine supplies the port front and starboard rear nozzles, and the other is vice versa. See extra image attached.

Interesting. How does that help in an engine-out scenario? Do you also have a 3 view of the stacked engine proposal? I have another alternative which I was sent by Barrington Bond sometime ago of twin pegasus with them placed back to back, with six nozzles (the two engines share the common central ones). It had a large dorsal intake to feed the rear engine.

Oh, I see - still very odd, but not as lossy. Thanks for the clarification!

Found this image on the inside cover of "Harrier: The Biography" by Jonathan Glancey. Image credit is courtesy of Phillip Jarrett. Book is OK, image is awesome, my scan is mediocre.
Another attempt at cleaning the image

Thorvic has made a splendid model of the P.1134.

the P.1150 was the first step to the unlucky P.1154. In fact the P.1150 was not powerful enough for the NATO NBMR.3 of 1961, so 2 evolutions followed.
the first was the the P.1154 (which used the same lift system as the Harrier, with PCB for supersonic flight), the second the P.1155. both were tendered for the NBMR.3...

The P.1155 was a backup for the P.1154, very similar but using lift-jets. This was much less practical than the P.1154, so the backup was... abandoned.

After that, the P.1154 was started for both the RAF and RN before beeing cancelled in February 1965, along the HS-681 transport...
Hi! P.1150.

The thread ought to be merged with the thread "Hawker Siddeley P.1154" because the P.1154 project has been well-documented in the literature on British jet fighters of the post-WW2 period as well as books on VTOL jet fighters.

Nice find uk 75, I always liked the P1154 and it is one of my favourite what if fighters, it always amazes me why the RAF finally went for the subsonic P1127 instead of the P1154,

But what would we have gained if it had gone into production?

A significantly stronger British aerospace industry for one thing.

Keep the RN out of it.

Hi! Sorry following model seems to be a single seater with bicycle type undercarriage. So it's a P.1154 for RAF dated 4.11.63.(Brooklands Museum)

The P1154 has been covered in so many books and articles. However, there is still no decent general arrangement drawing of the last version for the RAF before cancellation. This well known photo shows it.
The final version of the P1154RAF at cancellation is this model above, all I was asking for was a ga drawing of it.
The ones posted above have already appeared in other threads which cover development of the RAF and RN 1154. Please dont re post them here.

The wind tunnel model is pretty much the last version. The one posted after looks like a modern kit of some kind.

I'm not sure that is an 1154, the fwd nozzles appear to be stepped and the pylon into the wheel fairing on the wing remind me a of a later proposal

The undercarriage nacelle/pylon looks reminiscent of the later P.1214 to P.1216 studies, the tail fin too looks different from the P.1154 in having the ram-air intake at the root.
But it could have been a P.1154 model repurposed for later research.
Be good to see the labeling of the exhibit, but one thing for sure, a lot of the helpers at Brooklands know their Kingston projects off by heart.

This wind tunnel test model has tricycle landing gear. So this design was for the RN?
Tricycle undercarriage VTOL fighter design for the RAF ever existed?
I feel this design looks like wind tunnel test model. Wing plan form is different?

Nice to see one of my images getting traction here. Interesting that you guys think it might be a more advanced project than the P.1154 - at the time I captioned it, that hadn't occurred to me, so the mistake is all mine, not Brooklands' or Kingston staff's. So based on what y'all have suggested, I did a bit of looking through Tony Buttler's British Secret Projects, Jet Bombers Since 1949 (Midland, 2003) and found an illustration that resembles that model more closely. It appears to be the HS.1179L single-seat V/STOL project of mid 1968. There was also a two-seater with the same designation, the HS.1179M.

Here 'tis again, only correctly captioned this time.

Following on from that post, I can confirm that the following is, in fact a P.1154 (it has it written on the side) and it is located in a display case opposite where the model above is at Brooklands.

The BS.100 engine prototype at Yeovilton for interest's sake.

Thanks for the image of the model P1154 I compare the two

British super beauty!!
There are some differences between #73 two images. Air intake shape, canory and small air intakes located shoulder and before vertical tail stabilizer.
Is this drawing not enough for RAF final version?

Is this what you are after, Ralph?
Thanks this is the closest to the production version. In Michael Pryce's article which I dont have to hand there is a ga of the two seat trainer version which shows the cockpit glazing.
