New 2024 book content + Frank Whittle

This google blog software has problems in presentation for the fonts do not STAY the way you type or adjust them.....so, sorry about the variation below, which I have found impossible to correct.

AAIB discussion - select top right  "September (2)"

If Frank Whittle had been supported by aircraft manufacturers, the jet engine would have been available sooner. As it was, without such support (why did the RAF not go to them?), Frank had to study Engineering at university AND pass, before anybody would help. Thus 12Aprl1937 was the first Whittle jet engine run. The Lancaster, Halifax, Blenheim, Wellington were so slow that 55,000 aircrew lost their lives in WW2. The lesson from September 1940 was that fast fighters could easily pick a slow bomber and shoot it down - so you needed faster bombers A (as Frank wanted,)?  

But no, the ignorant Winston Churchills team (over ruling expert pilot Frank Whittle) decided to go for a one off demo aircraft, the E28/39, and then start again with the Meteor (Messerschmidt did not delay with a demo - straight to a fighter which did the demo bit in its initial flying) instead of a Canberra for 1943. The so late 1949 Canberra first flight (note especially that if Frank had been supported before his degree, that Canberra could have been 1939 or so!!!)..... see the Luftwaffe's bomber design (not initially used as such) June 1943 first flight : https://en.wikipedia.org/wiki/Arado_Ar_234  

Patentees in Britain have long been expected by the Government to also manufacture and test their own designs - such a crazy idea that Britain's Official's have still not even recognised of Frank Whittle's problems. Patents need to be searched by Business to invest, not expect the solo Design Engineer like me (software and logic), to learn how to make and test (you need a big building to test a jet engine) - who can afford the machine tools and the factory, let alone the IPR that a company has, to help think, calculate and launch a project?  

The new Labour Government wants more SME to be launched, but they have so little IPR, that they start way behind the big company with lots of IPR knowledge, and that costs - and sales so delayed too. We need Patentees to be supported by big Company, for the Law is a hugely difficult thing for an Engineer or Scientist to understand - a big company can protect the intrapreneur from all that employment law, business law, taxation law, marketing and sales drives .......and just allow the clever one to concentrate on their clever make it work thinking.

1Oct2024:  Just discovered in my local small cafe; VAT is now being charged on many items and has been for a few years, growing in extent over that time. Wow, not made public by Government, just known by cronies..... 

- the cafe manager is overwhelmed I was told, by all the paperwork needed now.



My new book “Tornado New Horizons” ISBN 979-8-32824-379-7 published in 2024 recently.
























What are we fighting for?  I was told "our World" in the 1970's, but I now know we have to do better than that, not take sides, but learn from others real experiences, and think, to construct the best for all of us.

1) Further to Chapter 1, Hypersonic missiles has become all the current NATO scary rage! Design of such was aerothermodynamic completed in the early 1960's by "my" Bristol Siddeley APRG, and it was shown that supersonic combustion (SCRAMJET) would be a benefit to higher thrust, for the potentially huge normal shock loss in the annulus would be eliminated! - but only if a flame could be stabilised without bigger pressure losses in the flame-holder combustion process. 

My 1964/5 BSc supersonic aerodynamics "step loss" project collaboration with Rod Clifford continued here, because his was the Practical discipline, and yes, combustion was him! See book "British Secret Projects". Supersonic combustion is extremely difficult - on Tornado, reheat combustion in the tailpipe starts at an inlet flow airspeed of (only!) about Mach 0.3 (imagine a candle in a 300 mph wind! ....and if at Mach 4 in the combustion duct? wow!!). Hypersonics was dropped in 1966 as far too expensive for Civil Airliners, and "Combat Engines" was formed from APRG Personnel, which eventually became the Turbo Union RB199 for Panavia's Tornado. 


Thus, you can see that I have always worked at the Requirements end of our Bristol engines, but also software made it far easier to understand how the RB199 engine worked, transient behaviours in 1971 too (never before done by calculation on any other engine at all!). The RB199 Vulcan so confirmed in 1973, and then Tornado in 1974, as I expected overall, with practical innovation of hardware tweaks on those initial flight engines, to eradicate a couple of operating problems.....all solved for Flight.

And thus also my annoyance at HS2 Ltd pursuing the Wrong Requirement......high speed was not the Industry requirement, which was for capacity not hugely expensive speed.











2) Further to my book page 188 (fusion power), the plasma dynamics are only sensor observed externally, so the knowledge of the flow inside the "plasma tube" is poor. Imagine air flow along a duct, the walls cause a boundary layer and it is well known that there is higher airspeed in the centre than near the edges (an airspeed profile). What is happening inside a tokamak magnet controlled high temperature plasma? I think we need to seed the plasma with "sparkly" grains, so that visual measurements can be made of the flow speed distribution across the plasma tube insides, for the temperature will melt a metal pressure or speed sensor! From speed can come pressure profiles....(PV = RT in aerodynamics). Then we will know what control mechanism is better/necessary, for currently we only know the outside surface characteristics of the tube, and not the bulk of it. We have to try!
