Posting a Diary Entry

Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.

When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.

If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.

ATTENTION: READ THE RULES.

  1. One diary daily maximum.
  2. Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
  3. No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries that already cover this topic), though fresh original analysis is always welcome.
  4. Use the "Body" textbox if your diary entry is longer than three paragraphs.
  5. Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
  6. Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
  7. Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.

Please begin with an informative title:

Sometimes Plato (427 BC – 347 BCE) hit the nail on the head; when he said ‘necessity (who) is the mother of invention’, he was obviously predicting what would happen to certain WW2 fighter aircraft and their engines! After the prototype Grumman F6F Hellcat flew, someone thought it would be a good idea to replace the Wright R-2600 Cyclone with the magnificent Pratt & Whitney R-2800 Double Wasp.

Intro

You must enter an Intro for your Diary Entry between 300 and 1150 characters long (that's approximately 50-175 words without any html or formatting markup).

The Hawker Tornado programme was dumped because the Rolls-Royce Vulture engine it shared with the Avro Manchester was failing (engine fires in the Avro Manchester – although it could have been sorted for a fighter application, maybe), so the Napier Sabre engine won out and the RAF got it’s sister aircraft, the Typhoon.

It was 1945, and the Japanese were losing the war – badly. Boeing B-29s were razing their cities to the ground, and they need a high-flying interceptor, fast. Using the Kawasaki Ki-61 Hein as a basis, the IJAAF try to build a manouverable fighter with genuine high-altitude performance, the Ki-61-II-KAI. Unfortunately, the temperamental inline of the new fighter – the Kawasaki Ha-140 - was unreliable, and when the factory where most were being built was flattened by a B-29 raid, the IJAAF was left with several hundred engineless airframes laying around. In desperation, the slim fuselage of three of these useless airframes were modified to take the only high-performance engine available, the 1,500 hp Mitsubishi Ha-112-II Kinsei …..the result wa the Ki-100-1b Goshikisentoki (or ‘Type 5 Fighter’). This was an absolute winner of a fighter ‘plane – the first examples of which reached Homeland Defence units in July, 1945 - and despite having a maximum speed of only 360 mph, they were manouverable, hard-hitting (2 x 20 mm Ho-5 cannon in the nose, 2 x 12.7 mm Ho-103 machineguns in the wings) and a danger not just to B-29s but even Mustangs, Hellcats and Corsairs. Fortunately for the Allies, the number of conversions and new-built aircraft were only enough to equip a handful of  IJAAF Sentai because of  the general disruption and destruction of the war industries.

The example you can see here was on display in the ‘Milestones of Flight’ Gallery at the RAF Museum, London, during my visit earlier this year (it is now on its way to RAF Museum,Cosford, as part of a general movement of airframes between the two sites). It was one of only four captured Japanese aircraft brought back to the U.K. after the end of the war for further study, out of over 60 selected by Air Intelligence Units - shipping space was given over to returning PoWs, of course. Two of the others ended up in museums –  a superb Mitsubishi Ki-46 “Dinah” at  the RAF Museum, Cosford, and the cockpit section of a Mitsubishi A6M5 “Zeke” in the Imperial War Museum, London. I have a distant link to the fourth airframe, in that the Kokusai Ki-86a Army Type 4 biplane trainer, a licence-built version of the Bücker Bü 131 Jungmann (and which would now be the only survivor) was burnt by RAF authorities at the then-RAF Wroughton in the 1950s - long before I got there as part of the Science Museum staff.

This Ki-100-1b is now the sole survivor of its type in the world, and its current state of preservation is a credit to the staff of the RAF Museum. If you are visiting the U.K. track it down, and view a marvellous example of aeronautical improvisation.
