Limitation imposed to preserve engine life and inability to run at maximum output are two very different things.

I believe in the case of the Maybach 230 the limitation was to avoid unnecessary engine wear, which seems logical given that the maximum torque was already produced by engine at 2500.

Personally, I have never seen any evidence to that the 2500 rpm governing was put in use because of troubles with the final drive or the engine itself.

Engine
The Panther was powered by a 700 PS (690 hp, 515 kW)/3000 rpm, 23.1 litre Maybach HL 230 P30 V-12 petrol engine that drove two front drive sprockets via the gearbox and steering unit. The engine was generally considered reliable, and had a fatigue life of up to 2000 kilometers. In order to minimize engine failures, the Panther engines were fitted with a governor in late 1943 that limited the engine revolutions to 2500 rpm and power to 600 PS (592 hp, 441 kW). The installation of the governor also dropped the tank's top speed from 55 km/h to 46 km/h.

700PS@3000rpms------55km/h on road, 15.6PS/ton

600PS@2500rpms-----46km/h on road. 13.3PS/ton

The engine has a volume of 23,095 cm³ (approx. 1,925 cm³ per cylinder) and a maximum output of 700 PS (690 hp, 515 kW) at 3,000 rpm. Maximum torque is 1850 Nm at 2,100 rpm. Typical output was 600 PS (592 hp, 441 kW) at 2,500 rpm.

The crankcase and block are made of cast grey iron. The cylinder heads are made from cast-iron. The engine weighs 1200 kg and its dimensions are 1000 x 1190 x 1310 mm. Aspiration is provided by four twin-choke Solex type 52JFF carburettors.

Maybach HL230 - Wikipedia, the free encyclopedia

What the Wikipedia source fails to say is that the engine reliability issues were solved in early 44, and the engine governor was dropped. By early 44 the HL230 engines in the Panthers Tigers were running safely and reliably at 700 PS continious power.

I see, but wikipedia is an open source that everyone and anyone can edit; personal opinion is heavily influencing the content of the articles, and in this case, it seems to be an opinion that the regulation was done to prevent failures, as no references is cited for it.

To me, the limitations to 2500 rpm seems to be a good practice to preserve engine lifespan while at the same time not effecting the tanks mobility in practical terms (as the last 500 rpm only gave the tank some extra speed, but no more extra torque that would be useful).

Germany was also the leader in radar infrared techonology, producing the best infrared imaging and being the first to deploy infrared equipment on smallarms AFV's a good number of vehicles (Inclduing the Pzkpfw.V Panther) being equipped with this in late 44 on the western front and enjoying amazing success.

This is a cut and paste from the very same claim you made earlier this year
http://www.ww2aircraft.net/forum/ww2-general/german-weaponology-12294-2.html#post332637
so why do you repeat it when you know it isn't true?
Perhaps this time instead of ignoring reality you could provide the examples where this 'amazing success' happened and thus show you are not making it all up.

Further demolition of your other claims can be found in the same thread:

Antiaircraft vehicles on Panther (IV) Flakpanzer Cölian 341 mit 3,7cm Flakzwilling 44.

In October of 1944 the Cölian was proposed as platform of a new armament. That was a pair of guns Flak 44 of 37mm mounted on chssis ausf G, this gun was a new design of Reinhmetall. Basically it was an aeronautical gun MK 103 adapted to receive the case of 263 mm in length of the projectile of 37 mm, it was operated by gases and belt fed.
it had a combined rate of fire of 500 rpm.
In order to lodge the gas conduct, the emplacement of the guns and mantlet of the twin assembly was modified. It also adapt a system of belt fed to this location to allow a fire with less interruptions (originally it was loaded with clips of 8 shots)

Effective ceiling stimated in 2500 meters.

The causes that finished this project were two:

A) Problems in the belt fed when the gun obtained its maximum elevation (85º)

B) The insistence of the WaffenAmt in an automatic gun of heavier caliber (superior to 37mm)

3 more drawings of the Flakpanzer Cölian 341 mit 3,7cm Flakzwilling 44.
In the second the polish illlustrator ( J Kolacha) made a little mistake, the guns could not elevate 90ª. It remained as projeckt only.

Nope, no demolition going on. You again just making stuff up.

Now stop being an arse and discontinue your childish attempts at derailing this thread.

Grat info!

Thank you, I need to add some about the JagdPanther wich is after all an specializated variant of the Panther.

The JagdPanther ( Sonderkraftfahrzeug Nr 173)

The Jagdpanther was the most sucessful variant of the Panther other than the main battle tank and it was designed from the start to carry the mighty 8,8 pak 43. This gun had a longer barrel and cartrigde case, improving considerabely the penetration power with relation to the Kwk 36 mounted in Tiger 1.

After the installation in the Elefant the german army sought a lighter, cheaper and more realiable plataform, like the panzer IV, but eventually it was considered too small chassis for this gun and the Panther was choosed instead.

The predecessor, Panzer IV mit 8,8 cm Pak 43.



Early development:

Jadgpanther , production and characteristics:

After tests of prototypes, it was then ordered to start the full-scale production in December of 1943. Jagdpanther's production at MIAG (Muhlenbau-Industrie AG) in Braunschweig started in January of 1944, while at MNH (Maschinenfabrik Niedersachsischen-Hanover) in Hannover in November of 1944. During the production, third assembly plant - MBA (Maschinenbau und Bahnbedarf) in Postdam-Brewitz also started producing Jagdpanthers. It was planned that production will reach output of 150 vehicles per month, but the highest output was in January of 1945, when 72 were produced.

A picture of one of the very first vehicles to be manufactured in october 1943, note the single block barreland pistol port in the side, characteristics that were deleted later




Overall from December of 1943 to March of 1945, only 392 were produced (chassis numbers 300001 to unknown and 303001 to unknown), although some sources state that about 413 to 417 were made since production continued until April of 1945 or 425 until May of 1945. The total number of Jagdpanthers produced was a direct result of Allied bomber raids, which caused much destruction and disruption at two production centers (MIAG and MNH).

Jagdpanther was based on standard Panther chassis with superstructure being an extension of the upper front hull (80mm thick armor) and side (50mm thick armor) plates. The new superstructure housed the fighting compartment with main hatch in the rear wall that was used by the crew to enter and exit the vehicle as well to load the ammunition.

Two other hatches were mounted on the roof of the superstructure. Jagdpanther's equipment differed from Panther's, only in hatch covers and small number of other components. The vehicle weighted 46 tons and was powered by 12 cylinder Maybach HL 230 P30 23.1 liter gasoline engine capable of making Jagdpanther reach maximum speed of 46km/h (average road speed was 25km/h).

Its fuel capacity was 700 liters and maximum range on road was 160km. Jagdpanther used Zahnradfabrik AK 7-200 transmission (7 forward and 1 reverse gear), later upgraded with newer and strengthened AK 7-400.

Jagdpanther was operated by five men crew - commander, gunner, loader, driver and radio operator. The driver sat at the front left and radio-operator/machine gunner on the other side of the gun. Behind them both sat the gunner and the loader, while at the rear of the fighting compartment sat the commander.

The driver had a periscope in the front superstructure next to the gun mount. Early models were mounted with two vision slots for the driver, while mid and late models produced starting February of 1944 had single vision slot. Other periscopes were mounted on the roof of the superstructure and were used by commander and loader.

One photo for the freak, maniac, obsessed modeller. Panther ausf A after long front service.

Note the polished innner roadwheel rims, evidently the rubber was completely worn out by the track teeth.

Nice CB!

Other nice ones, this is for a good diorama ( I never had patiente to build that ) the Panther "221" belonging to 4th panzerregiment based in North Italy. This is an ausf D with ausf A turret.

Those are fantastic photos.

That must have been one hell of a punch!
