Not sure, but it does get old hearing it over and over...curious where this myth about the Ta 152H as a Höhenjäger comes from ?
Yup on all accounts....the Tank was never used and I mean NEVER used in airfield protection for ANY Me 262 unit.
the Doras of the Würger staffel all 5-6 of them tired to protect Galland circus JV 44.
the Dora-9's of III./JG 54 did a crap job of protecting Kommando Nowotny.
NO other jet unit ever had a high protection staffel of any 109 nor Fw 190's
MacArther said:Two of my books site that the Kurt fighters were used for Jet top cover, which proves yet another thing that is wrong with my books. First one I noticed, right after I got it, was the statement "The Zero could acieve higher speeds that early adversaries early in the war because of its methanol boost."
delcyros said:Some technical thoughts.
High altitude = low air density (low speed of sound) = very cold temperature
So a good high altitude fighter has to overcome these major problems.
It needs to have a low wingload (therefor big wings are better),
some cockpit modifications (the first to name a pressurized cockpit and a reliable canopy defrozing system). Then it needs de-icing or heating systems for the control surfaces and (very important) for the powerplant as well.
Then we have a plane to be physical capable to sail in high alt but it still has no sufficient power and the plane needs time to climb to that altitude ( additional fuel capacity), yeah, introduce some very powerful compressors to the engine in order to keep its engine power output at high altitudes (this increases weight...arggghhh (that´s usually the point when designers get crazy). Not the latest You will have to modify the propeller design (low Speed of Sound= BIG PROBLEM) in order to deal with near Mach speeds at the screwstips.
Some last words on the weaponry: low airdesnity also implies a lower desgree of stability, you will need to factor the recoil forces of guns much more, especially for wingmounted ones...
Don't remember where I read it but flying the 109 over 30kft was said to be like trying to balance while standing on a tight rope.
Under wing air intakes?

you needed a wide-bladed propeller(s) to move the air
A shorter, lower-aspect ratio wing could be made to work in relatively straight flight, but one hard turn and you'd fall thousands of feet before you recovered.
The real trick was to get fuel and oil (automotive oil does NOT work!) that could be made to work at low partial pressure
many American planes were limited by the R-2800 engine because the magnetos lost insulation and leaked spark at about 30,000 feet and higher.
Initially it struggled at high altitude when compared to its main adversary, the Bf-109
The tailoring of the supercharger ratios and propellor rection gearing meant that individual engine types could be altered for their roles. So you end up with the suffix 'F' for Spitfires with engines tuned for medium to high altitde, 'LF" for Spitfires with engines tuned for medium to low altitudes and "HF" for Spitfires with engines tuned to high altitudes.

Why was this?
