What made you say he is a journalist? You might like to read this to see who he was: https://en.wikipedia.org/wiki/Cyril_Lovesey Only Rolls-Royce 'Chief Engineer (Aircraft Engines)' then deputy director of engineering and a member of the Aero Engine Division board of directors before he retired in 1964. Not sure why you might think a journalist would give a lecture on this subject, but hay-ho. This is his lecture that was then printed in the aviation journal. Also, your may be interested in the extract below from: http://www.team.net/html/fot/1999-12/msg00015.html "A.C. 'Cyril' Lovesey' became Chief Experimental Engineer after the death of Mr Ellor. in 1940. It is generally accepted in the world of engineering that Cyril Lovesey was the finest development engineer in the world throughout his working life - (I believe his skill, by example, has never been superceded). He was a great character, and together with a first class Science Degree, he was qualified in design and had a 'seat of the pants' feel for engineering excellence - like Sir Henry Royce. An example of Mr Lovesey's job on the Merlin engine was the fact that he was responsible for the mechanical integrity of the engine throughout it's many modifications and the doubling of its power from the start to the finish of the war. One story I remember of him was when several engineers from outside Rolls (during the war engineers often met from all over England to 'pool' knowledge and ideas) became 'turbo' experts. It came to the point that many engineers were insisting on a 'turbocharged' Merlin engine to the point that government 'pressure' was being leveled at Rolls to do something about it. The Rolls engineers (who had ignored directives) got thoroughly pissed of with the suggestion, because they thought, quite rightly as it turned out, that the 'smart arses' had not done their homework. It finally got to the point (by shear devilment of Earnest Hives the head of the company) that Cyril Lovesey was sent to give a talk on the 'turbo' thing to about three dozen 'wizz kids' who were insisting on the 'Merlin turbo.' - Mr Lovesey, after making sure everyone was comfortable said words to the effect-" Happy landings, Talisman

Development of the Rolls-Royce Merlin from 1939 to 1945 A Lecture Delivered by Mr. A. C. Lovesey to the de Havilland Aircraft Company Technical Department in November, 1945. [ame]http://www.wwiiaircraftperformance.org/merlin-lovesey.pdf[/ame] Page 223 says: "The first operational use of this fuel was against the flying bombs in the middle of 1944. Subsequently the whole of A.D.G.B. Was put on this fuel. Later it was used by the Second Tactical Air Force during and after the invasion of the Continent." This is evidence to show that the whole of Air Defence Great Britain was using 150 grade fuel, including all its Spitfire Mk IX squadrons, before D-Day. The Normandy map is due to cover the South of England and the English Channel, as well as France. A.D.G.B took part in D-Day operations and also flew sorties on the continent. 2nd TAF used 150 grade fuel, including in its Spitfire Mk IX squadrons. Therefore, I submit that a 25lbs boost Spit Mk IX would not be out of place on the upcoming DCS Normandy Map. Whether or not we eventually get a 25lbs Spit Mk IX is in the hands of the model developers, but I believe that there is clearly enough evidence to show that it would not be out of place for the WWII project.

I suspect that many of us feel the same and that this is part of the reason, along with many others, why WWII popularity in DCS is very slow at the moment. There are lots of us watching and waiting and hoping. I am not launching into purchasing lots of aircraft models yet, as the general flying environment, including air-to-air visibility, has yet to deliver or fill me with confidence for the future; meanwhile, I am mostly flying other WWII simulations and I am just living in hope regarding DCS at the moment :( Happy landings, Talisman

Hi Folks, I find FF works great in DCS. I have a Saitek Cybog Evo Force Feedback joystick (with my own stock of half a dozen second-hand spare sticks in the cupboard ready to go), a FF Gametrix Jet-Seat and a FF Audio FX headset. The immersion is great and I can only imagine what this would be like with Oculus Rift as well! Thank you DCS for giving us FF :) :joystick: Happy landings, Talisman P.S. I find FF joystick helps me fly faster, optimise trim better, fly more accurately and sense a feeling of flying through atmosphere, rather than a vacuum.

This thing is Kurfurst, I am not sure that is the "general idea" at all and I suggest that it may be wrong to assume that. My understanding is that DCS are just giving us the Spit Mk IX as a stand alone nice aircraft to have that can be flown on whatever map is available. The way DCS is delivering the WWII project is not very joined up for understandable historical business reasons I believe, which is why in another thread I asked for detail of what the DCS vision is for WWII. This is a difficult project for DCS to deliver and it is difficult for many of us to understand how and/or why it is being delivered the way it is. The thing is, on the one hand there is historical aircraft of the time to consider and on the other there is the plane set that has already started to be delivered. In RL, Spitfire Mk IX were not up against 190 Dora and 109-K versions on every single mission undertaken. However, in DCS WWII the Spitfire and all other Allied aircraft are very much up against the 190 Dora and 109-K every single sortie. In DCS world the whole LW is represented by these 2 top ranking aircraft types and the Me 262 is due in the not too distant future too, so surely this needs to be taken into account. Give the RAF and USA its top ranking aircraft, like the Tempest V, Spit XIV and higher fuel grade performing USA aircraft like the Mustang and then work back from there and I suggest that more DCS customers will feel well treated and considered. If delivery of aircraft types is done in a more joined up way from now on, more of us will be at ease. However, it is becoming apparent that the DCS business model is not geared to deliver us an historically joined up programme of aircraft, though I stand to be corrected if I have got that wrong. So, we can expect more threads and posts along the lines of what we have here until enough of the Allied and Axis plane sets are built up and delivered over time, on a "this aircraft is nice to have and fly basis" to give us proper historical map options. I suggest it is going to take a long time to give many WWII enthusiasts the competitive WWII environment they would like to see. Happy landings, Talisman

Flying the DCS Spit Mk IX on the DCS Normandy map will not be all about D-Day. Also, if the Normandy map includes the Channel and the South of England, the Spit Mk IX 25lbs would not be out of place and I have to disagree with you Klem. As a side note it may be worth remembering that ADGB took part in D-Day. Any way, the map is clearly not all about D-Day. They are calling it the Normandy map, but we are getting the English Channel and South Coast of England I believe. If that is correct, clearly the map building potential is not all about D Day. In fact the plane set we have is somewhat divorced from D-Day, so nothing is joined up. My point is that if we have a map that includes Normandy, the English Channel and the South of England, then that is the area of operations we have for the plane set we are given. So, the options we are given includes ADGB and the Spitfire Mk IX they flew in 44/45 (or are we not to bother defending UK airfields when the LW come across the Channel on the DCS map?) as well as 2nd TAF. Lets not get hidebound about this, we have the whole map and plane set to use for our pleasure as delivered by DCS. I am very much looking forward to launching on a raiding mission in a Spitfire Mk IX across the English Channel and back (I hope, lol). I am looking forward to all the opportunities the new map will give us, not just D-Day (particularly as the LW was not about much at the time). I hope you "get it" now. Happy landings, Talisman

This regarding Operation Crossbow 1944: http://www.spitfireperformance.com/merlin66_18_25b.jpg Spitfire Mk IX 150 Grade fuel: All squadrons of this type will be similarly modified when present difficulties (back-fires) are overcome. The back-fire issue was quickly overcome and Cabinet meetings are extremely high level, so all Spitfire Mk IX squadrons will have been modified thereafter for "Crossbow". Happy landings, Talisman

Below is extract from:http://www.wwiiaircraftperformance.org/150grade/150-grade-fuel.html PLEASE NOTE: INCLUDES 2 OPERATIONAL REPORTS OF SPITFIRE MK IX 25LBS BOOST ADGB SQUADORNS ON OFFENSIVE OPERATIONS FROM ENGLAND TO THE CONTINENT AND BACK IN 1944. By mid August the V-1 diver threat was largly eliminated with the advance of the allied armies beyond the launching areas. The ADGB squadrons that had converted to 150 grade fuel now found more time to operate over the continent. The Spitfire IX Squadrons were permanently pulled off anti-diver duty on 10 August and went over completely to escort work, sweeps and armed recces. They paid their first visit to Germany on 27 August 1944. http://www.wwiiaircraftperformance.org/150grade/1-squadron-oprep-27aug44.jpg http://www.wwiiaircraftperformance.org/150grade/165_oprep_16sept44.jpg Happy landings, Talisman

Into Service with the Royal Air Force Following successful testing, the Spitfire IX's Merlin 66 was cleared in March 1944 to use +25 lbs, obtainable with 150 grade fuel. In early May, No. 1 and No. 165 Squadrons comprising the Predannack Wing, were the first to convert their Spitfires to +25 lbs boost and employ 150 grade fuel on operations. The above extract is from: http://www.wwiiaircraftperformance.org/150grade/150-grade-fuel.html It is worth noting that the Predannack Wing is quoted as the 'first', not the 'only' or the 'last'. 'First' means that more Spitfire Mk IX aircraft converted after No 1 and 165 Squadrons. Happy landings, Talisman

Sorry Kurfurst, you lost me there :huh: Are you saying that 150 grade fuel was fantasy for ADGB fighters in 1944 and later with 2nd TAF? Also, are you saying that the DCS LW fighters are not using the cutting edge fuel of the time and the jet engine Me 262 is not on the way? I am trying to contribute on-the-level to this debate, but I just don't understand your 'fantasy' remark when there is all the evidence being presented concerning 150 grade fuel. All I am saying is that the Spit Mk IX 25lbs might not be so out of place on the ED Normandy map as it includes the ADGB area of operations (which clearly operated with more than just 2 Spit Mk IX 25lbs squadrons) as well as the 2nd TAF area of operations. 150 grade fuel was firstly in very common use with ADGB fighters and then by 2nd TAF. Happy landings, Talisman

Although, I suggest that it could be fair to say that it was very common indeed for ADGB fighters to use 150 grade fuel for a large part of 1944; therefore, since the ADGB area of operations is to be included on the Normandy map, the Spit 25lbs would not be out of place. Also, after it was common for ADGB fighters to use 150 grade it was then common for 2nd TAF to use 150 grade fuel. This would appear to suggest that 150 grade fuel would be a fair inclusion on the map that ED is providing. Particularly as late war cutting edge fuels are being modelled for the LW types by ED; why leave the cutting edge fuel out for the Allied side if it is provided for the Axis types being sold?

Kurfurst, I am writing to correct your wrong assumption. If you read the distribution list at the top of the letter you will see all the 'action' addressees and that the one 'for information' addressee is listed in brackets. This is the service writing convention of the time and should make it clear which units are to action and which units are included on the distribution just for information purposes. As you can see, only one unit was for 'information only' on this letter, all the others were for 'action'. P.S. Note in brackets 10 Gp was for only 2 sqns. Happy landings, Talisman

Given the extract below and that, unless I am mistaken, the so named 'Normandy map' will include the English Channel and the South of England, I suggest that the 25lb Spit would not be out of place on the map. I say this because ADGB defended the part of GB, including the English Channel, that will be on the WWII map provided by ED for us to fly on. Please correct me if I am wrong, but I think everyone is agreed that the 25lbs Spit was used by ADGB from Spring 1944. If areas defended by ADGB will be depicted on the Normandy map, then I suggest that it follows that the 25lbs Spit will be very historical and in keeping with the map. Just a thought :thumbup: Normandy: June–August 1944[edit] After the Normandy landings, some Spitfires (Griffon and Merlin engine marks) were retained in Britain to counter the V-1 flying bomb offensive in mid-1944 as part of the ADGB.[94] Supplies of a new aviation fuel, which was called "150 Grade", arrived from America in March 1944 and sufficient quantities were available to be used by ADGB fighters as the V-1 offensive started. The new fuel enabled the Rolls-Royce Merlin and Griffon engines to operate at higher boost pressures, especially at lower altitudes, for the duration of the anti-V-1 campaign.[95] The above extract was taken from: https://en.wikipedia.org/wiki/Supermarine_Spitfire_operational_history Happy landings, Talisman

OK, I have to confess that all this jet stuff normally leaves me cold and as a WWII prop job fan I tend to skim through most of these screen shots with a yawn. However, this shot is hot :thumbup: Thanks for posting and congratulations, very nice work :) Happy landings, Talisman

Just want to get my ducks in a row (quack-quack), I like to fly fast (quick-quick) :) I am so keen to go :joystick: Happy landings, Talisman

Quick question for the devs. Can we choose not to have the rear view mirror (improve frame rate) and if we can and choose not to have it, do we get any speed increase due to less drag? Happy landings, Talisman

Perhaps the Mig engine fire suppression system, once operated, allows for some continued flying time. Not sure if that is what we are seeing or not, but just a thought. Happy landings, Talisman

FF through the joystick is a must for me and surely must be kept in development for the future, as without it the aircraft just feels dead to me. With FF the aircraft is alive! The Mig 15 and P51D are brilliant with FF and I am very much looking forward to FF with the Spitfire Mk IX and XIV :) Also, FF with the Gametrix FF seat is brilliant and adds another level of immersion :thumbup: I have a FF headset, FF joystick and FF Gametrix seat and the immersion is great! I just don't understand why there are so few FF products available for flight simulation. FF helps me fly faster, with more precision, climb more efficiently, and is great for feeling trim and being able to set trim quickly to the optimum, and sensing the aircraft around you with the feeling of actually flying through atmosphere. Happy landings, Talisman

I am sure anyone involved with avaiation can fully understand your point, just as the reader can fully understand his point too. Happy landings, Talisman

Yes, looking forward to it getting better and better. Right now it is hard to get any sort of historic overall representation. For example, in WWII every sortie by a P51D or the upcoming Spitfire Mk IX was not against the top draw LW aircraft currently depicted by the 109K and 190D. However, in DCS WWII every sortie by the Mustang or upcoming Spit Mk IX will be against the Dora or Kurfurst, rather than more common LW aircraft types of the time. It will be even harder for some when the Me262 arrives if there are not more top draw Allied aircraft like the Tempest V and USA aircraft types running on the historical higher grade fuel. At least we are due to get the Spitfire Mk XIV soon to add to the mix :) Happy landings, Talisman

I find this very interesting as it shows that multiple use of the 5 min combat setting could be expected in a single sortie and gives guidance regarding the subsequent effect on fuel consumption :thumbup: Happy landings, Talisman

Allegedly slower as well as faster but within a small margin perhaps. But still not soothing, LOL.

Surely this is the bit to focus on: "The Spitfire development was started by obtaining a lot of original materials including wind tunnel tests, flight tests measurements, prop (we use wooden Rotol in the model) wind tunnel tests. Wind tunnel tests both for the prop and the airframe were performed for high Mach numbers as well. So, the parts of the FM (airframe, prop, radiators) were carefully tuned separately to get the specified parameters of the real prototypes. Then, the blower of the existed V1650-7 engine was changed to fit Merlin 66 gear ratios, the automatic shift was set to new pressure." I say this because I would have thought that the mathematics and modern computer modeling, under the expertise of Yo-Yo, would be able to produce results that would help negate any historical human error in test piloting together with any human error in engineering differences at the time to a considerable extent. I think it is testament to the professionalism of Yo-Yo that he has given us this information in a transparent and up-front way. So lets all try to be grown-up with our responses. Yes, I would love to see a 1944/45 25lbs boost model of what is essentially a 1943 aircraft, but I think perhaps not everyone would agree and I do not intend to be churlish about it.
