Código: Seleccionar todo
De 500m nada. Aquí nadie ha mencionado el 37mm, estábamos hablando de un proyectil HEAT y ni siquiera hablábamos de pentraciones sobre un tanque en concreto.
Hay tablas que ponen penetración en el concreto.
Entretanto hay que tener poca memoria, porque si nos volvemos al escrito que és totalmente ilogico, veremos que tiene esto escrito.
HEAT projectiles have the same penetration capabilities regardless of range. However their maximum effective range is usually low because of the shape of the projectile and the low muzzle velocity. Determining the maximum effective range is quite difficult.
German HEAT projectiles had muzzle velocities of less than 600m/s, and usually less than 450m/s. Although Hogg quotes various effective ranges in German Artillery of World War Two of 1,000m and more, these must be viewed with some suspicion. A report from the Infanterie-Division “Grossdeutschland” on 3 April 1943 as quoted in Jentz’ Panzer Truppen Vol 2 gives an indication of the true effective range:
“Our own Panzerkopfgranate (i.e. APCBC or APCR) are exceptionally effective and amazingly accurate. However, to the contrary, due to its large dispersion the HL/B-Granaten (shaped charge shells - i.e. HEAT) is usable at a maximum range of 500 metres. If a hit is obtained at long range by expenditure of a high number of rounds, the effect of the HL/B Granate is good. However the troops have no faith in the HL/B-Granate. It is desired that the supply of Panzer-Kopfgranaten be increased.”
At the time the division had 10 Pz.Kpfw.IV with 7,5cm Kw.K.37 L/24 and 75 Pz.Kpfw.IV with the longer barrelled 7,5cm Kw.K.40 L/43, as well as various other vehicles. The report quoted above indicates that the maximum effective range of Gr.38 Hl/B is 500m for these vehicles. Hits could be achieved at greater ranges but only by firing many rounds.
For other weapons estimation of the maximum effective range can be made by examining the muzzle velocity. Few guns exceeded the muzzle velocity of the vehicles quoted above, and in any case by only a small amount, so it is reasonable to assume that 500m was about the maximum effective range of any German HEAT projectile, with many guns having less than this figure. This subject will be will be developed further in the Data Analysis section.
Atención a la negrita de arriba.
Tenian 10 cañones de 37 mm. (Lease 75 mm, corrigido a posteriori)
Tenian 75 cañones de 75 mm.
Tenian varios otros veiculos.
Pero el relactorio aleman que menciona el escritor no dice que cañon, y el escritor se basea en esto para decir que el alcanze maximo efectico del Gr.38 Hl/B seria 500 m. ESTO PARA TODOS LOS CAÑONES!!!!!!
? Como se va a dar credito en esta una información ? Yo puedo no conocer nada (por lo que dicen mis compañeros), pero al menos se que la velocidad que sale el HEAT de un cañon o de otro és totalmente diferente, portanto su efectividad también seria diferente, pero el tan afamado escritor que pone esta conclusión debe tener unos conocimientos de fisica impresionantes pués lo pone todo en la misma cazuela.
El relactorio de los alemanes probablemente se referia solamente al cañon corto (pura suposición mia), no hay mas que un relactorio, como se sabe el porque lo hizieron... y el escritor lo presenta como un dato general aplicable a todos los HEAT y a todos los cañones...
No questiono la menor efectividad de los HEAT esto no esta en discusión, la question son estes 500 metros que el nuevo EINSTEIN lo ha sacado de su manga.
