Hawker P.1035 Hawk. Source grade 1.

I came across some unattributed notes and sketches of mine from long ago. The description of Hawker's P.1035 match those widely spread -- based on the F.2/43 Fury but B.41-powered with a long jet pipe and the Fury cockpit moved forward.

Questions

1 - Has anyone seen a drawing of the P.1035 with a higher source grade?

2 - Can anyone confirm the 'Hawk' name? (I also noted 'Jet Fury' but assume that to be a description rather than an appellation.)

3 - Is a tricycle landing gear a safe assumption or might the P.1035 have inherited the Fury u/c arrangement?

A scale modeller depicting the P.1035 retained the Fury gear. A variation with that gear is in the Scale Modelling, Fan Art & Profiles section.

From Brooklands:

P.1035 Jet fighter. P.1026 with RR B.41 jet engine.
P.1026 Fighter to F2/43, Griffon.

No drawings yet for these there, AFAIK.

Thanks overscan,

"P.1026 with RR B.41 jet engine" sounds like the descriptions that I've read attributed to the P.1035.

In the Scale Modelling section, Justo has posted an image of a wind tunnel model. It has a low-mounted (I think) Fury wing, raided tailplane, and split jet pipes. Much more P.1040-looking other than the wing planform. Perhaps this is actually P.1035 and the long jet pipe model was "P.1026 with RR B.41 jet engine"?

maybe this can be usefull:
...When details of the Nene (RB.41) became available in the autumn of 1944 Hawker shemed
Project P.1035. This proposed moving the cockpit to the nose and mounting the engine amidships in the fuselage of the F.2/43 fighter(which became the Centaurus powered Fury and Sea Fury) with
a long jetpipe exhausting at the tail.
It was a stepping stone to a more refined design,and any resemblance to the Fury slowly disappeared.
It now included wing-root intakes ( although the Fury's elliptical wing planform was retained) with the
fuselage mounted engine exhausting through short bifurcated jetpipes on the fuselage sides
just aft of the wing trailing edge...

That's a drawing I produced with Lark some years ago (when my nick was "Libélula")

Photoshop experiments with P.1026 drawing and P.1040 nose to recreate the P.1035

Excellent feedback, folks. Many thanks.

Pometablava & Lark: I love your reconstruction -- especially the 'slot' intakes. Like you, I assumed that a Fury-winged aircraft would retain its original armament (rather than risking gun gas injestion). I too began by overlaying the P.1040 onto a Fury.

Overscan & smurf: that answers the question. In 1943, P.1035 meets the usual descriptions (long jet pipe, etc.). By 1944, it was morphing into something much more like the P.1040.

Now I am intrigued by the P.1031. I wonder, was the engine placed Yak-15 style? Was the Rolls-Royce P.40 an axial-flow jet? Great stuff ... more to dig for! ;D

Thanks to all.

Sorry I didn't note the source of my photocopy. It's filed with my Hawker stuff but I think it's from a more general book. if it turns up, I'll post. I also remember seeing a picture of a Fury-winged jet, not one of those posted. I've a pile of stuff to file from our last house move, but I'm working on a warship article, so it may be some time.

I'll post more info form mags&book this evening and also a P 1031 "photoshop experiment". Lark and me were also interested on P 1031 too.

Joe: Thanks for the clarification. So, it sounds like the P.1040-style canopy was used from the outset (I'd interpreted moving the Fury cockpit forward literally and included the Fury sliding hood with that).

Antonio: interesting take on the P.1031. Any idea whether the P.40 engine was an axial or centrifugal flow type? It seemed to me that directing the thrust beneath the fuselage would be trickier for a 'chubby' centrifugal type.

This got me pondering a possible connection between the P.1031's nose-mounted engine and the P.1040's split jet pipes. Might exploring a more direct jet Fury conversion have got Camm et al considering split jet pipes to begin with?

Cheers Overscan.

That makes it seem probably that the Rolls-Royce P.40 was either another Derwent derivative study or an early stage of the B.41 Nene.

I'm assuming that "lateral intakes" simply distinguished side intakes from a nose intake. Otherwise, it implies more Attacker-like intakes.

Some info from "smurf". He doesn't recall the source unfortunately.
It's from Robert Jackson's "Hawker Hunter - The Operational Record" (ISBN 1-85310-048-X / Airlife, 1989).

Apophenia,

That text from Overscan is the most precise description I've read about the P.1035 to date. I think there is no need now to post description from my own sources. When produced the P.1035 drawing, we assumed literally that was described as a "minimal-change jet conversion from P.1026" . It was clear (from literature) that nose section from P.1026 was replaced with that seen on the P.1040. According to "minimal change philosophy" we assumed that engine was feed from the existing intakes at P.1026 wing (early jets feeded from little intakes) and landing gear was classical. (Compared to contemporary designs evolved from existing aircraft it was logical. Supermarine did that with Spiteful to Attacker).

After reading the text from Francis K. Mason book, I guess P.1035 was more similar to your recreation (trycicle gear and lateral P.1040 style intakes) than that from Lark and me.

What do you think Lark? ;)

First P.1040 drawing in Brooklands collection is described as having Fury wings.

It sounds like there was little to choose between the late stages of the P.1035 and the start of the P.1040. Perhaps the design office at Kingston simply changed the designation to avoid internal confusion as the design continued to evolve?

Antonio: IIRC, the F6U Pirate had 'slot' intakes very much like those in your P.1035 drawing.

In my opinion 2 different designations are justified. There is some conceptual and chronological paralelism between "Jet Fury" and "Jet Thunderbolt". Both started as a way to quickly obtain a jet fighter from an existing piston engined design. In both cases it was found that straight conversion resulted in poor performance designs (In the P.1035 the long jet exhaust pipe originated lost of thrust and engine performance was limited in early jets). So the idea didn't work and much redesign was needed in order to get a high performance jet fighter, definetively a new design. P.1035 gave pass to P.1040 as Jet Thunderbolt to Model 23 Thunderjet. P.1035 and Jet Thunderbolt also had a very short existence (few months).

I think P.1035 and P.1040 main differences are engine exhaust and wing/tail surfaces. I believe it should be enough to justify different project numbers. However every designer has its own criteria about project numbers. For instance, AP-10 was the model number at Republic for USAAC P-47, P-47A and P-47B Thunderbolt. (P-47 and P-47A were radicaly different designs from P-47B)

Regards,

Antonio

The full honour for the drawing of the very early P.1035 must go to Pometablava.
I only put some pieces of the puzzle together..

Let's say 50% Lark + 50% Pometablava then ;)

Antonio,

I agree. The different designations were justified. The split jet pipe is a big change from the original straight-through type envisioned. And, as you suggest, once the P.1040 adopts a new wing design, there's little if anything of the original Fury left.

erm its not a wind tunnel model (the caption is wrong!) this one is a 1/72 wooden model i put together a few years ago for Tony Buttler as a discussion piece, i guess someone took a photo of the model at a show and assumed it was an original?

i based my model on an early P.1040? (P.1035?) design artwork drawing published in 'Sydney Camm and the Hurricane' (ref to follow) which shows a 'Tempest winged' 'Hawk' with teardrop canopy like the prototype P.1040, the drawing is not the best quality but seems to be the earlist surviving incarnation of the type?

cheers, Joe
