Obviously.Soren said:I could repost a German test with an excellent condition La-5FN if it would interest you guys ??
Dogwalker said:Obviously.
But is that reported on wikipedia too?
Dogwalker said:Thinking at the usual bias when a enemy aircraft was officially tested by a WWII air force, it dont' seems the La-5 to be so bad. It was described as pratically in pair with Bf 109G and FW 190 A8.
Tanks for your kindness upon my fonts.Soren said:Wikipedia Dogwalker ? No, although you might rely on such places for your info I don't.
http://www.ww2aircraft.net/forum/aviation/why-allied-soviet-equipment-superior-3319-5.htmlSoren said:And according to extensive German testing of a La-5FN, it was found that it couldn't turn as well as a cleanly loaded Bf-109. (German 109 pilots attest to this fact as-well)
The following excerpts are taken from "Luftwaffe Test Pilot" by Hans Werner Lerche. He flew virtually all captured Allied aircraft and most German types, including experimental models. His book includes a detailed wartime test report prepared by him, on the La5FN.
Hans Werner Lerche:
He tested an La5FN powered by an M- 82FNV engine in September 1944 at Gross Schimanen, East Prussia.
"It was obvious from the start that this aircraft was no longer comparable with the earlier Soviet fighter types of rather primitive construction, and that it was a very serious opponent to our fighters below 3000m (10,000ft). "
He describes having been made giddy by carbon monoxide entering the cockpit during his first flight; thereafter he chose to always wear an oxygen mask when flying it. He also says the noise from its engine was deafening and that he always had to put cotton wool in his ears when aboard.
His report lists the following figures:
Max speed 403mph at 20,670 ft
Rate of climb, rated power, at 300m (984ft) 16.17 m/s
Rate of climb, rated power, at 4000m (13,120 ft) 13 m/s
Rate of climb, rated power, at 7000m (22,320 ft) 6 m/s
Climb to 16,400ft (5000m) in 4min 42 sec
Service Ceiling 31,170 ft (9500m)
Power Plant: Shvetsov M- 82FNV 1,850h.p
Armament: 2x 20mm cannon with 200 rounds each.
Armour protection 57mm armoured glass windscreen, 68mm rear armoured glass plate for head protection, 7mm rear armour plate.
The summary of his report (marked 'SECRET') was sent to Messerschmitt, Dornier, Heinkel and Junkers, as well as the RLM, and reads:
"The LA 5FN represents a great improvement in performance, flying characteristics and serviceability compared to earlier Russian fighters, and its performance below 3000m is particularly noteworthy. Maximum speed is below that of our fighters at all altitudes; best climbing speed near ground level lies between those of the 190 and 109. In the climb, and turns below 3000m, the La5FN is a worthy opponent, particularly for the 190. the type's manufacturing shortcomings would hardly affect the Russians who are used to inferior flying characteristics. Range is short, flight endurance at rated power being about 40 minutes."
The report detail goes into great depth about the machine's handling characteristics, so I'll just pull out a few bits:
"Full throttle altitudes are so low that full emergency power cannot be achieved in either climbing or horizontal flight. "
"Surface finish, especially that of the wings (wood) is good; the sideways and forward extending slats fit very accurately. "
"The pilot's sitting position is comfortable. In flight the strong exhaust fumes are troublesome. The oxygen system is a copy of the German diaphragm flow economiser system."
"Longitudinal stability at normal angles of attack with undercarriage and flaps retracted or extended, is surprisingly good, even in a full power climb. In steep turns elevator forces are fully positive and fairly high, so that nose trim is advisable in a sustained turn.
Yawing oscillations damp out slowly, nevertheless gun aiming is quite easy. Roll response to rudder is mild; the nose rises or falls in response to rudder, but this is not particularly disturbing. "
He goes on to describe the forgiving stall characteristics which he ascribes to the extension of the slats.
"The smallest turning circle at rated power at 2400m is about 28/30 sec for a stable 360 degree turn at constant height. This implies a minimum time for a 360 degree turn at 1000m, with emergency power, of about 25 sec. "
He then says the aircraft has a tendency to porpoise on landing because the elevators become immersed in the wing wake and the undercarriage is poorly damped.
The tactical conclusions and advice offered to German fighter pilots are as follows:
"The La 5FN is best suited to low altitude combat by virtue of its engine performance. Its top speed at ground level is slightly below that of the 190 and 109 (using MW 50). The 109 with MW 50 is superior over the whole height band in top speed and climb rate. Acceleration is comparable. Aileron effectiveness is better than the 109. Turning times at ground level are better than the 190 and worse than the 109.
In rate of climb the 190 is poorer until 3000m. Because of its greater weight the 190 accelerates less well than the La5FN, but by the same token is superior in the dive. It is basically right to dive away like an American Thunderbolt when flying a 190, thereafter to pull away in a high speed shallow climb to reach a new attacking position, not to let the speed drop and to avoid prolonged turning dogfights."
Dogwalker said:Tanks for your kindness upon my fonts.
I didn't ask if You read it on wikipedia, but if it's the same report.
It is.
Dogwalker said:So, it seems that Hans Werner Lerche was capable to make the La-5 turn better, climb better and accelerate better, at low altitude (the altitude at wich the most part of the dogfights over the russian front took part), than one of the best fighter around in 1943.
Dogwalker said:It needs to remember that the maximum speed acheived by Lerche is superior to that achieved by FW 190A and Bf 109G in several tests.
It seems not so bad to me.
Udet said:The Yak-9T (a heavier version) and Yak-3 saw service in the ground attack mode, even though they were not designed to perform as such. The Yaks -all variants- were extremely easy to shoot down; they were virtually uncapable of sustaining damage.
Udet said:Hastily built machines, not of great quality, poorly equipped -i.e. no radios on most planes throughout the entire war- and manned by pilots who were likewise hastily trained and put into the cockpits.
Udet said:No match against the Fw 190 D-9 and Ta-152.
Udet said:Another one of the many allied urban legends "Luftwaffe fighter units were issued orders to not engage the Yaks at low altitude..". Funny. A waste of time.
Udet said:Finally, Soren´s comments on the over-inflated Lavochkins are correct.
Ur going to sit there and state that u ignore the combat effectiveness of the 2 best prop jobs in the entire War???? Are u an idiot or just clinically retarded??? Talking with Willi Reschke many years ago solidified this that no Soviet fighter could come close to either aircraft at any altitude...priller said:What a silly claim. The numbers of these aircraft were so insignificant as to be utterly ignored.
PipsPriller said:Well, well. Here's another who can only resort to insults.
