I agree, and that is why I asked.
I knew you did. I was just elaborating on your point. It would great for a Moderator, pilot, and military crew chief to weigh in with their criteria and detailed explanation of their choice. How about it?
I always use max power available to the pilot for comparison as explained later. If the value used for the Bf-109 is not the max power available, please let me know.I have heavier weight for the P-47 and lighter for the Bf (it depends on model and source I guess).You are comparing WEP which was 5 min power. '
but in what quantityThe Bf109G/AS was available in 1st half 44.
Because that is where the bombers were and where the Germans had to operate at to affect the bomber offensive. On the Western front, this is where the air war would be won or lost, not at low altitude as was the Eastern front. Why would you only want to look at just low altitude?And you only look at 15.000ft and above? Hmmm why would you limit the comparison there?
trickier only that the P-47 power advantage doesn't transfer into climb superiority. However, it is not a dog. The P-47D-25 climb performance at these altitudes are superior to the Fw-190A, similar to the Fw-190D-9 and the Bf-109, but noticeably less than the Bf-109KClimb is not trickier check a table for the P-47 it was a horrible climber.
I choose to compare aircraft at best rated hp because this is what the pilots used when they needed it. Whenever combat reports include power settings your read statements that indicated they went full bore, throttle full forward, I was pulling more than 75", etc. Also, I select fuel quantities that are on a more even levels just in order to compare aircraft at similar load factors. As far as altitude goes I usually go from SL to 35k, but in this case, I wanted to emphasis that were it mattered, American aircraft was not constrained by load factors.My point being that you can't just grab some stats keep the ones you like post them online and show that one aircraft or another ''rocked''.
All aircraft had their good and bad points and their best altitudes.US aircraft were heavy because they needed to be ( more fuel) this affected acceleration and climb rate.However thanks to their supercharger they had superior energy at higher altitudes.For these reasons they would not be a good choice for Germany or the SU ,since they used their aircraft in lower altitudes.
Internal fuel for the P-47 goes from a design load of 205 gallons to a full internal load of 370 gallons. The 14,500 lbs represent a P-47D-25 with full internal fuel, extra water and oil, on departure for a long escort or strike mission. The Bf-109 carries about 106 gallons. Comparing a Bf-109 with106gallons of fuel to a fully loaded P-47, with 379 gallons of fuel does not seem useful in understanding the full performance of the airframe.Also the weight of the P-47 does not agree with what i have seen in flight sims and wikipedia (14.500-17.000 loaded).
Your weight of the Bf is the one of K4 that is the heaviest variant built.Strange that both differences point to one direction.I think you have taken the performance of the Bf109G6 and divided by the weight of the K4 take a look at the DB605DB/DC with MW-50 .
I've used Kurfust's site for the Bf data plus what he has posted here .Flight sims have an actual paying audience plus they have to create a whole physics engine so they definitely try to get the most accurate data .If you look at their forums you'll see that many people complain about some performance differences and the producers come in and address those problems.If you're asking me if it's a better source than MW site the answer is yes with a capital Y.WW2 aircraft didn't run on 10% fuel with engine at 110% ,that's not realistic.
I was never a pilot in the military, only a UH-60 crew chief.
As for the topic of the thread, I have not decided on any criteria as of this time. I have however enjoyed reading the thread. I will eventually chime in with my thoughts however, after I have thought about it some more.
A question from a "dummy" are these flight test results taking into account all the variables that affect flight such as temp, humidity etc?
Also as mentioned in other threads is fit and finish of the aircraft was it polished or painted. there are so many variables I find it hard to believe a Russian/LW/RAF/ USAAF test results would concur with other as they are all using different aircraft with different engines with different hours
Air france accident appears to be very tragic and very embarassing. With full respect to the crew, i feel that-sometimes- commercial pilots in their high tech ,everything automatic comfortable cocpits , eventually lose the "feeling" of flying , they transform from pilots to train drivers . Their world is the colour tft screens , and the buttons . Simulators are good, training is good, but perhaps from time to time should practise basic flying in low tech aircrafts
Ps if such accidents happen to modern fully equiped planes, i can not speculate what accidents rates sufferd the poorly equiped russian fighters in the russian winters
Some how I got the impression you also had a license or were working on the hours to get one.
I took a few rides on the crashhawk in the 80's.
I unfortunately have not done any private flying in years...
The "Crashhawk" is a great aircraft. I really miss her, but that unfortunately does not pertain this topic...
That's what i have been saying all along.
@Lighthunmust : I have no problem admitting the superiority of the P-47 and P-51 in high altitude against the standard Bf109 and Fw190.Against the Bf AS the difference is very small and in the field it would not be noticed.But neither do I forget what happens at lower altitudes.If the American aircraft were given to Germany they would not do well simple as that.
Set your TiVo to TCM HD for Sunday 1:00AM MST so you can see Germany using P-51s to shoot down P-47s.
For sims: I never suggested that someone limit himself to only one source.But these people have a financial reason to use the most accurate data available and their audience demands it.
Huh?
I would suggest that is not the best criteria for determining accurate data. The truth would be much better.
Thats what research and good sources are for. Its just my opinion but money shouldn't be an incentive for research. And Flight Sim sites - again, in my opinion - are not the place to look for data.
Lighting - can you list what criteria so far (that everyone has agreed) that would be acceptable? Don't want to add something already posted.
@davpalr : i generally agree with what you wrote ,note that people were quick to attack me but noone bothered to actually check your data.I don't think you made a deliberate mistake but i will tell you again that WEP is not the best way to compare power.Best if you use combat.
Please clarify this statement. Is 846 an airspeed number of some sort?Now you mentioned numbers. For the Bf109AS in this or another forum someone posted the number of new and converted AS in 1st half '44 as 846.That's not an insignificant number.
An undeniably true statement, but to dismiss allied aircraft as being inferior to German aircraft and won only because of numbers is incorrect. Except for the jet, all the advanced German propeller driven aircraft could be matched by Allied aircraft of equal or better performance, except maybe the Ta-152H at altitudes above 35k ft. But then I don't thing nitrous was particularly rocket science.However the numerical difference between Allies and Luftwaffe was so great that even if ALL Bf 's were of the AS type it would make no difference .The air war was pure attrition.
This is a valid point and one I have pondered for quite a while. In my mind there are only two useful comparisons between aircraft. One, which I did above, is to compare the aircraft under similar load levels, which provides capability of the aircraft design itself. This is certainly the easiest do and certainly tends to represent parity of combat in some scenario, though maybe fleeting or rare, of battle. The one you describe is the conditions likely at the onset of battle. This one is quite variable and tends to take a lot of work. Just looking at the P-47D-25. If we took it at a long distance escort and combat starts right after external tank jettison, then the combat weight of the P-47 would be close to the 14,000 lb point that you indicated, while the Bf-109 would be at a bit less, burning off climb fuel, than published loaded weight. However in the summer of '44 and later, when mainland European fields became available, then the P-47 would be more likely to have the smaller fuel weight.For the P-47 -Bf weights: maybe then we need to see what the weight would be at the point of battle.Both aircraft would have burned a lot of fuel.
Again, industry, trying to model aircraft for operations simulator purposes, spend millions of dollars on software and hardware, something I do not think game people can do or have the expertise to do. This is not to say that video game software is not a valid tool for training pilots, it is, just that it is not a precise copy of aircraft aerodynamics and environment. And whatever you do, do not believe that if you are good in a video simulator, that you would be good in an aircraft. The environment is totally different with g loads, vertigo, vibration, noise, aircraft physical communications with the pilot, physical exertions, FEAR, etc., etc., etc.For sims: I never suggested that someone limit himself to only one source.But these people have a financial reason to use the most accurate data available and their audience demands it.
What is the truth?
@Lighthunmust : Ehm you know that we don't have that channel in Greece right?
