137 Squadron.







Welcome to the newsletter for June,this has been an interesting month having contained our first AGM you will find a full report a little further down. You may have noticed that I have reverted back to the old photo as the last one I used created much mirth and merriment among
family and acquaintances, there is no doubt that I look better behind dark glasses.

I must take this opportunity to thank Brian Barnes for the lend of his Radio so that we can measure and scan it so that Gunnar can fit it into the radio compartment on his CAD drawings.

                                         P6969 
Joined 263 Squadron on the 19th of July 1940 and was believed shot down off Dodman PointCornwall by an Arado AR 196 of Bordfliegerstaffel 5/96. PO Kenneth Graham posted as missing. 

Thanks to Niall Corduroy's book Whirlwind for the above information.


The Last Flight of P6966

It is often overlooked that, by the Summer of 1940, the air battle for Scotland had been fought and won just as the Battle of Britain was beginning. The Luftwaffe was turning its attention to the South of England and taking the pressure off the Scottish RAF bases. There was still enemy activity but on a lesser scale, so the airfields could be used to rest operational squadrons from the south and to allow other units to work up on newer types of aircraft.

The largest airfield in Scotland was RAF Grangemouth. It had been opened by Scottish Aviation Limited in the Summer of 1939 as a training centre for the RAF Volunteer Reserve, and also quickly attracted civil passenger flights. Of course, all that changed with the outbreak of the war and Grangemouth was transferred to Fighter Command. The first residents were the Spitfires of 602 (City of Glasgow) Squadron, who were tasked with the defence of the shipyards and foundries of Central Scotland. 602 were joined by 141 Squadron in late 1939, who brought Gladiators and Blenheim Ifs to assist with local defence. 141’s primary mission, however, was to bring the Boulton Paul Defiant into operational service.

By the early Summer of 1940 Grangemouth was an extremely busty place, housing aircraft of many types and roles, including the Hurricanes of the re-formed 263 Squadron. 263 also had a local defence remit but their primary role was to shake the bugs out of the Westland Whirlwind.
In July 1940 my late father George Walker was a 13-year-old Air Training Corps member and an avid plane spotter, so he was very quick to notice the new shape and sound in the skies above the town. He was, of course, very familiar with the types operating from Grangemouth and had even flown from there several times on air experience flights provided by the station’s De Havilland Dominie communications aircraft. This new shape was twin-engined but clearly not a Blenheim. Sightings of this mysterious aircraft would remain rare, however, with 263’s Hurricanes being by far the most common sight.

In later years Dad couldn’t be clear as to when he found out the identity of this strange shape in the local skies, but during the school Summer holiday in 1940 he heard the sound of one of them overhead and he and my Granddad watched as it spiraled upwards into the sky. He then saw a glint as something fell away from the aircraft, followed by a black dot. The Whirlwind tipped on its nose and dived straight down, out of sight. The black dot deployed its parachute and floated serenely to earth. Dad and his pals got on their bikes and headed for the crash site but the aircraft had impacted soft ground known as Dunmore Moss and there wasn't much to be seen. The airframe had disintegrated and heavy items had buried themselves in the damp earth. Since the boys had comfortably beaten the RAF to the crash site – not unusual! – they had a quick look but soon decided there was nothing of interest and retreated to watch as the recovery crew finally arrived from Grangemouth and collected as much as they could of the shattered airframe. It seems the RAF then spent a couple of days looking into the hole and scratching their heads before deciding the best course of action was to simply fill it in.

The boys were luckier a few weeks later when 263’s Hurricane L1083 crashed into a field almost at the bottom of his street. This time a belt of .303 ammunition was “liberated” from the scene before the RAF arrived. They retreated to the sanctuary of Granddad’s air raid shelter where the cartridges were taken apart and the cordite propellant removed, to provide fuel for a series of cardboard and paper rockets! 

Many thanks to John Walker for the above account.  

What if? P6994 had been adopted by the United States Airforce and they had started their own construction line would we have seen one like this. just think of the various designs this would have created.

Many thanks also to Phil Box for sending me this picture of his finished 1/72 Airfix Whirlwind, well done Phil, just proves that you can still do wonders with old kits like this.









Also from the Hyperscale site a picture of the new 1/48 Whirlwind test shots from Trumpeter this gives you a chance to compare the two kits.

Newsletter for May


Chris Hayward

263 Squadron Crest.






 


Welcome to the May newsletter, first off an apology is due because somehow or other all the photographs have disappeared from the earlier blogs and I have no idea as to how that happened, if anyone has any ideas I would love to know the reason why then hopefully I can stop it happening again.

I would like to thank the Royal Antediluvian Order of Buffaloes, St Leonards Lodge No 1601 and Bedford and District Provincial Grand Lodge for their kind donation to our project.

Congratulations must go the the Peoples Mosquito having taken the big step in cutting the first wood for the wings, I had hoped that we might just beat them to it but it was not to be, so well done guys and may your glue always set firm.

Things are still progressing slowly, as you know we now have the material in the workshop to start the build of the rear fuselage, Mike has a Spitfire in there at the moment that he wants to move out before work commences, we have to realise that he is doing this project without charge so of course his main business comes first otherwise there will be no workshop in which to construct it, so we have to fit in around what he has to do.



What are the chances?

Ten sections of ‘top hat’ stringer, to precise dimensions, were needed to complete the inventory of materials for the rear fuselage.  A month-long search showed that sections to these dimensions were not available anywhere ‘off the shelf’. Getting them made to the precise dimensions looked like an expensive business, some quotes being upwards of £1,000.
Matt B called in on the off-chance at a company – Milton Precision Engineering (http://www.miltonprecision.co.uk/)  – literally a three-minute walk from his office in Cambridge. They were able to manufacture the 10 lengths to the exact specification for £65! Now we have all the material we need for the rear fuselage.  Just goes to show, it never hurts to ask locally..
 

The AGM is still ahead on the 24th of May, the main part of the meeting will be to agree the constitution, when that is done we can approach HMR&C and apply for charity status so that we can gain from the benefit of gift aid.


The First AGM of the Project will be held at
 
The Premier Inn Hotel.  
Alvington Lane, 
Brympton d'Evercy, 
Yeovil, 
Somerset,
BA22 8UX.



In the Conference room on the 24th of May 2014



The meeting will start at 11:00hrs followed by a break for lunch and then resume at 14:00hrs with a talk on the project by Patrice Moreau followed by The Eye of the Storm' - Westland' the fixed wing years and Quo Vadis a talk by Dave Gibbings.

All are welcome.

If you are planning to attend please can you let me know so that we can work out the numbers for food.

There will be a raffle and also there will be goodies for sale, all proceeds of which will to go towards the build.


 There are still a number of prints available from me at the address at the end of this newsletter, the print is unframed and carries the signature of the artist David Gibbings also in facsimile the signatures of Penrose, Petter and Davenport the cost is £25.00 which includes postage and packing.

Whirlwind Stories


Bellows Argentina No2

Delivered to 263 Squadron on the 3rd of November 1941, on the 25th of July she was hit by a Beaufort AW274 and repaired onsite, on the 12th of December 1942 he went to the Station flight at Colerne but was later damaged and returned to Westland but was re-categorised as unrepairable possibly due to extensive corrosion. Total ops hours 80.5

Arthur Davenport.

Arthur Davenport F.R.Ae.S (1891 to 1976) was a British aircraft engineer working for Westland Aircraft.
When the Westland Aircraft Works was created by the Petter twins in 1915, Arthur was one of the first draughtsmen to be recruited from Petter's Ltd . He was chief designer from 1919, working under the direction of Teddy Petter from May 1934 until 1944, when Petter left and Davenport became technical director. According to Harald Penrose, he was made the scapegoat for the late delivery of the Wyvern and headed into retirement in March 1952.
In the 1920s, when most aircraft were biplanes, Arthur was a strong proponent of the monoplane Most of his monoplane designs were high-winged or parasol, culminating in the Lysander. During his career he was involved in the design of the following fixed-wing aircraft.
  • Westland Limousine  Chief draughtsman
  • Westland Wagtail  Chief draughtsman/Designer
  • Westland Weasel  Chief draughtsman/Designer
  • Westland Woodpigeon
  • Westland Widgeon  Chief designer
  • Westland Wizard
  • Westland Wapiti/Wallace
  • Westland Interceptor
  • Westland Wessex
  • Westland PV.3
  • Westland Wallace
  • Westland PV.7
  • Westland F.7/30
  • Westland Lysander
  • Westland Whirlwind
  • Westland Welkin
  • Westland Wyvern  Technical director
In the early 1930s he worked with Juan de la Cierva to develop the Cierva C.29 and CL-20 auto-gyros.
 It was this interest in rotary winged aircraft that would lead Westland to manufacture Sikorsky helicopters in the early 1950s.

From our correspondent Jim Munro

Separately just to let you know that Prof Glyn Davies of Imperial College, London has written the first ever biography on W.E.W. ('Teddy') Petter who of course designed the Whirlwind, Lysander, Gnat, Canberra and had a major hand in the English Electric Lightning.   The book launch will take place at AgustaWestland at Yeovil on Thursday 19th June........starting time 'TBD'.

Wanted

Coffman Starter, not used on the Whirlwind for starting the engines but used as a flare dispenser, sited in the rear fuselage and covered by a cloth cover, the exit hole for the flare is on the top of the fuselage about half way down towards the tail, a donation would be preferable but could buy it if the price is right.



CAD Work 

At the moment we can't show the plans that Mike will use to construct her but these CAD pictures will give you an idea of the extent that Gunnar has gone to to resurrect the Whirlwind using crash pictures and studying manufacturers pictures and plans that still exist. I will put up more next month.

Newsletter for May


Newsletter for April





Chris Hayward 

It's been quite a busy month one way or the other, what with the arrangements for the AGM, the visit to Duxford for the BAPC meeting, the delivery of the first metal sheeting to the workshop at Ripley so that work can start on the rear fuselage, Gunnar has been fine tuning the plans so that Mike will have the best foundations with which to start with, and it looks as if we now have the final drawings in house for the retractable tail wheel.

Team Profile of Rene Peters



 Hello, may I please take this opportunity to introduce myself.


 My name is René Peters, I am 45 years old and live in The Netherlands with my wife and two sons. By profession I am a freelance 3D engineer specialising and working with SolidWorks. Projects varying from motorcycle exhaust systems, sewer pumps through to kitchen equipment.


My hobbies include Scouting, veteran cars and motorcycling, and since my childhood I have been fascinated by all types of military vehicles and combat aircraft from the First and Second World Wars. During our holidays we always try to visit a military museum or a battlefield, so we have seen many places from the Battle of the Bulge to Verdun and the Somme and have also visited the Normandy Beaches.

Whilst browsing the internet I came across the site http://3dengineers.co.uk. Where a Bugatti T35 had been reverse engineered. It was on this site that I first came across the Whirlwind Fighter project. The original Westland wind tunnel model had been 3D scanned to produce additional CAD information. Triggered by this I then visited the Whirlwind website and subsequently offered my help to the CAD team. My first intention was to help with the 20 mm. cannons but the Whirlwind team had a bigger challenge for me, namely to make a start on the Rolls Royce V12 Peregrine engine. (Indeed, this turned out to be a bigger challenge!)

The only information available was the original drawings from Rolls Royce with the external dimensions and many photographs of a crashed Peregrine engine in Derby.  It goes without saying that a lot of information was missing, later to be filled in by logical thinking and technical insight. The supercharger and carburetors from the engine in Derby were missing, they remain a complete grey area.  If you just happen to have a supercharger in your attic - please get in touch!
Nevertheless, I am progressing, and with luck and many hours work the Westland Whirlwind will get her engines back!

 

                                                                                                       

  Dave Tanner, Mike Eastman, Matt Bearman, Chris Hayward, Patrice Moreau.
Five members of the team attended the BAPC meeting on the first of March at Duxford to hear the committee accept us as provisional members, during the next twelve months we have to make a presentation to the committee as to what the project is all about, and this will take place during the meeting at Doncaster on the 16th of August and will be given by Matt Bearman. At the end of or our first year the BAPC will vote as to whether or not we can become full members.

Begging Bowl

As you will surely appreciate raising money for a project like this is never easy, we have sufficient funds now to nearly complete the rear fuselage and tail section but that still leaves the rest of the airframe that we need to fund.

If you wish to donate please don't use Paypal as they take a lump of your donation and deplete the amount that you give us, either pop a cheque in the post to my address or contact me and I will let you have the paying in details, you can if you wish, make monthly donations via a standing order.

I am asking people to have a look and see if you have a few pounds that you can spare, or visit our Shop  and buy some goodies, I also still have some prints of the Whirlwind prototype available so if you missed it last time take this opportunity to get your print now.


 The print of the Whirlwind prototype. This is unframed and costs £25.00 which includes postage and packing. It is signed by the Artist Dave Gibbings MBE also in facsimile by Petter, Penrose and Davenport.

William Edward Willoughby "Teddy" Petter


William Edward Willoughby "Teddy" Petter CBE (8 August 1908, Highgate in Middlesex - 1 May 1968, Béruges) was a British aircraft designer. He is noted for Westland's wartime aeroplanes, the Canberra, the early design of the Lightning, and his last plane, the Folland Gnat.
Edward was the son of Sir Ernest Petter (26 May 1873 - 18 July 1954), who founded the Petters Limited engineering company. He was a descendant of one of the twin sons that founded Westland in 1915, the company being a separation of the aircraft business from Petter engines. It built flying boats. Both were Yeovil companies.
He attended the prestigious Marlborough College in Wiltshire. He studied the Mechanical Sciences Tripos at Gonville and Caius College, Cambridge, where he graduated in 1929. He won the John Bernard Seely Prize for aeronautics.

Westland

Petter joined Westland, the family firm, as a graduate apprentice in 1929. He became Technical Director in 1935. This appointment was not welcomed by older members of the management, who left. In 1935 Westland set up its aircraft subsidiary. Westland was taken over by John Brown Ltd of Clydebank in 1938.
He designed the Lysander. Originally created as an army cooperation aircraft, in the second world war it was used for transporting spies into France.

Petter's next plane was the twin-engined Whirlwind (which was one of the fastest aeroplanes in the world at the time). Not many were built. His last plane for Westland was the high-altitude twin-engine Welkin. It had a pressurised cockpit and was designed to intercept German reconnaissance aircraft. Around 100 were built. At this time Westland was mostly building Spitfires, under contract.

Petter left Westland in December 1944, after wanting to take over production as well as design. They chose to concentrate on helicopters through a link-up with Sikorsky.
He went to English Electric as Chief Engineer who were then moving into aircraft design, at Warton near Preston, having been involved in building aircraft under contract during the war. While at EE, under the leadership of George Nelson, he designed the Canberra. This plane was based on a Westland design for a jet bomber, created by Westland's Chief Engineer, Arthur Davenport. The aircraft would stay in operation in the RAF for 57 years until June 2006. The Americans built it as the Martin B-57 Canberra, being heavily used in Vietnam.

He started the work on what would become the Lightning. He split with EE in 1950 over the direction of aircraft design, he favoring the small over the large. He also wanted to be in charge of production as well as design. Petter was replaced as Chief Engineer by Frederick Page, previously his assistant.
The Lighting remains the only all-British Mach 2 aircraft. The plane has been described as fifteen tonnes of screaming aluminum.

Petter joined Folland Aircraft Limited in Hamble, Hampshire as Chief Engineer in 1951, and took some colleagues from English Electric. At Folland, he designed the Midge, which first flew 11 August 1954, and the Gnat training jet (first flight 18 July 1955). He was also responsible for early work on the Red Dean air-to-air missile before this work was transferred to Vickers. The Gnat was entirely his design; it was his attempt to make an affordable and easy-to-build fighter. He felt that other contemporary fighter aircraft were too big and expensive.
Petter became Managing Director of Folland in 1954 when Henry Folland died. Folland Aircraft was bought by Hawker Siddeley in 1959, which kept the Folland name until 1963. Petter left when Hawker Siddeley took over; he did not like working for large organisations, preferring to run projects himself. Colleagues found him authoritarian and eccentric - some described him as likeable but difficult. His manner was likened to that of a sixth form maths tutor. He was known as an excellent leader of teams, so long as things went as he wanted.
On leaving Folland / Hawker Siddeley, Petter left the aircraft industry completely. He moved to Switzerland.

Petter had two younger brothers and a younger sister. He married and had three daughters (including two born in 1936 and 1938). He died in Poitou-Charentes in France aged 59. Petter married Claude Marguerite Juliette Munier, from Geneva. She died in 1975, having suffered for a long time from Parkinson's disease.
