WW2 fighters turn rate

Recommended Posts

What was the optimum air speed or engine power for a WW2 fighter to make the tightest horizontal turn? I know it's not the most precise question due to many WW2 fighters, but I quess there was a general air speed and power setting to make best turns...

Which fighter? And, the tightest turn is almost always at a speed well-below what we consider optimal corner-speed.

Assuming a clean configuration with half-fuel, below 10,000 feet (3048 meters), it would most likely range from a high at 250-280mph/400-450 kph at about 4.5-5.5 Gs, down to a low of about half that speed (approximately 140-150 mph/225-241 kph at 2.5-3 Gs). This is, of course, assuming one wishes to fly in a sustained 360-degree turn. The radius of the turn would range from just under 600 feet/200 meters at low speed, to almost 1100 feet/335 meters at high speed

Thanks for your quick answers, I assume the turn is made with extend flaps?

 

Most assumptions are clean unless the aircraft has flaps/slats for the specific purpose of maneuvering (most modern fighters).  The reason was given in the link provided by manukar...but basically, flaps provide extra lift but at the expense of a lot of increased drag.  It may work for a emergency 'snap' maneuver, but you will kill a lot of energy doing it.  It is not something you would plan a sustained turn on, again, unless the flaps/slats were designed to be used in this way.

Thanks for your answers and links. Some interesting reading and technical data...
