Victor Crescent Wing

Many years ago, I remember seeing an excellent article on the benefits of the crescent wing designed for the HP Victor V-bomber. It had a swept-back root, a less swept-back centre section and an unswept outer section.

The prototype had a noticeable 3-section wing planform, but this seems to have been smoothed out in production. Anyone got a plan-view of the prototype to confirm this?

I understand this wing shape was so good, pilots said the aircraft would land itself!

By the way, I saw the prototype fly over the Sussex coast a number of times, and the fuselage was painted dark green with a red cheat line.

Those were the days of experimentation in design, sadly now gone…

Do show us the final product, i may whant a copy of the plan if it flys.

Thanks Ollie. I’m doing the Supermarine Type 510 as well, that will be a simpler build as the wing is much less complicated, and also the tail surfaces are low mounted and larger.

I suspect the HP88 model’s wing wasn’t developing enough lift and the Rapier L1 may not have been man enough to power it, so there’s a way to go yet.

XN923 have you repaired the wing yet?

I decided on a more comprehensive rebuild which included moving the c/g, reducing weight, strengthening the wing join and increasing dihedral. I’ll probably do all that then use it as a prototype for a new model.

In the book of Charles E Brown photographs ‘Camera Above The Clouds’ page 130 has a fantastic air to air of the prototype Victor taken on 10/7/53.
The fuselage is certainly very black with red cheat line, all the rest of the airframe is silver.
Strange that such a stunning airframe/colourscheme combination has not been published more often.

Sorry to bump up an old thread but I have read Rowland Whites excellent book Vulcan 607 and in it there is a colour picture of 771.

The accompanying caption states that Sir Frederick Handley Page personally chose the colour scheme of gloss black and silver with a distinctive red cheat line, there is also the most impressive photo I have ever seen of a Victor inverted, rolling off the top of a loop!!!!!.

Regards,

John.

I will try & dig my file out, i made 1/200 scale models of WB771 & the Valiant B2, i found the copy of the original Vickers plans for the Valiant but have not found the Victors. I had 5 or 6 colour photos of 771 & it was definately gloss black in those.

Sorry to keep going on about this, but all 6 published references that I have state black – and they could easily all have perpetuated a mistake. I am very inclined to accept the eyewitness acount of bri, but would really like some further confirmation – surely somebody took a colour photograph at the time? It is important for me because I would like my personal “First Flights” database to be as accurate as possible!
Let’s put it this way – if one other person (e.g. Albert Ross) can also provide a “dark green” eyewitness account of the colour, I’ll believe it (and thus prove all the books wrong!)

A caption in “Postwar Military Aircraft: 6” published by Ian Allan states “the new red and black colour scheme personally chosen by Sir Frederick”, but in the course of research I have seen so many perpetuated mistakes in print (and especially on the web) that I am still dubious and would like further confirmation that it really was black and not dark green – I am that kind of anorak!

Hear hear. Putnams is not the gospel many take it to be. After a bit of research at the PRO I can point a number of little errors in the Blackburn’s example – and some not so little. The problem is, published sources tend to reproduce previous errors. I can easily see how dark green could be mistaken for black.

Prototype WB771 was originally silver & was painted gloss black with a red cheatline with the fin, tailplane, wings & a section of the belly remaining silver for the Farnboro airshow, it then broke up at Cranfield on a low level high speed run due to fatigue of the single fixing bolt connecting the tailplane to the fin.

WB771 made an appearance at the Farnborough Air Show in 1953, with the aircraft painted in spiffy colors — black fuselage with a red cheatline and silver wings. Trials showed the basic design to be sound, with some corrections needed. Unfortunately, one of the corrections was discovered very much the hard way, when WB771 was lost in a crash on 14 July 1954 while on a low-level run. The tail assembly was weak and tore off, with test pilot Ronald Ecclestone and his crew all killed.

* The second prototype, WB775, which featured a reinforced tail, performed its initial flight on 11 September 1954. It had the same spiffy color scheme that had been applied to the first prototypte, and actually took a joyride to the Farnborough air show during the initial flight. It was fitted with operational kit.

From the Vector site, black fuselage.

“Am I right in thinking that the original research for the crescent wing came from Arado and was ‘spoils of war’ – being a proposed upgrade for the Ar234? There’s a project for you ‘Luftwaffe ’46’ fans.”

I have a sneaky feeling (having read an article a few years ago) it was Blohm & Voss who did alot of the wartime research into the crescent wing, the long term aim being to create a jet bomber capable of bombing the USA.

Thanks guys,
Brought back memories of a Jetex-powered Attacker I did…… 50 years ago.

These are no jetex. These fly on a relatively new fangled thing called rapiers.
They are basicaly single shot cadboard tubes full of propellant that you put in a cardboard tube in the model, drop a fuse in, light the fuse and launch.

One semi-flight – I got a perfectly straight, low flight but the model touched down before the motor ran out. I broke the wing on the second flight sadly. Wing is now repaired but fuse needs recovering. It will fly again soon.

I look forward to a flight report. I hope you have drawn up a plan of this as i may be after a copy if you get it flying.
I would think Mike Stuart would be interested to if it flew.

This site sheds some light on the Victor protos, their usage and paint schemes.

Sorry, according to my Putnam’s again (and other sources) it was 3 bolts which sheared due to fatigue cracks around their fixing holes, so subsequent aircraft had 4 bolts in a sandwich construction and a smaller tail fin to reduce flutter.
Still wondering about the colour – “matt black” according to various sources including Putnam’s!

My favourite V-bomber too – especially as I lived with them at Cottesmore for 18 months.
I am intrigued by the mention of “dark green” as my Putnam’s Handley Page “bible” states “matt black” and will now have a pencilled correction on page 503. Is there no colour photograph of the prototype in this colour scheme anywhere, to clinch it?
