Jet engines are "trimmed" on the ground to give a certain thrust at a given RPM (temperature and density altitude is also considered). If the maintainer trims the engine within the required parameters, the pilot should see a certain speed, EPR, and fuel flow at a specific altitude and the aircraft should see all this at a specificed true airspeed. All of this is designed into the aircraft (at least the ones I've worked with). There are some exceptions but this is the norm for jet aircraft.wmaxt said:The power output of any piston engine is a curve. That curve is optimized to place max power at the point where it is most usefull. 2/3 throttle may represent 40% power while 85% throttle may be 90% power these examples are dependant on cam/ignition timing, boost, type of boost, fuel, and the designated use the combination is set up for. Throttle/Power is only linear in jet engines and then only after a certain power output is reached (maybe Flyboy can enlighten us on that score)

The Bf 109's range only became a factor when the Luftwaffe switched to attacking London, before then the 109's range wasn't a problem while attacking the RAF's 11 Group airfields , they had enough to both escort the bombers and engage in combat.syscom3 said:I maintain that if the -109's had more endurance, they could have had longer escort times for the bombers and wouldnt have to break off contact(s) so soon to return back to base. The RAF loss's would have increased.
The biggest problem I have with the Me-262 is its configuration. While it definitely made obsolete all the previous fighters, it was technilogical dead end similar to the CSS Virginia, would instantaneously made wooden ships obsolete, nevertheless did not advance past the Civil War. The P-80 configuration, which integrated the engine into the airframe, was clearly superior and can be seen in modern aircraft. The configuration of the Me-262, and the Meteor, did not advance very far after the war and died out with the YAK-25/28 (there may have been some French copies). What did make a major impact on future aircraft design was German advance aircraft design work including swept wing and possible the axial flow jet engine (I don't know much about engine development). Among the WWII fighters, the Me-262 was head and shoulders above their capability, and, if they were introduce enmasse before D-day, the war could certainly have been impacted against the allies. However, it would have soon been surpassed by both allied jet fighter development and by contemporary German jet fighter development (I think Germany would have maintained a lead in jet fighter technology until the allies applied the weight of its industry to jet fighter development). All in all, it was an impressive aircraft that surpassed contemporary designs, it just didn't have a lot of places to go as a fighter.
I disagree somewhat, as the P-80 would've fallen prey to the Me-262 as-well had they ever met.
The Me-262 incoperated so much new technology into one that although having two outboard engines was a small, and I mean SMALL disadvantage, all the new extra features more than made up for that. Besides although the P-80 featured a fuselage mounted engine it lost allot of thrust because of the lenght of the air-intake, something the Germans already knew from experiments - hence the outboard engine placements on their serviceable jets. The P-80 was also at a serious disadvantage in wing design, having alot more drag to deal with, esp. at high speeds - and the fact that the Me-262 featured full span slats for slow speed fighting and the P-80 didn't, certainly didn't help matters for the USAAF either.
And worthy of note is also that the actual production version of the P-80 was far less nimble than YP-80 and XP-80 prototypes - which were probably already slightly less nimble than the Me-262.
And although I agree outboard mounted engines wasn't the future of the Jet fighter, it nonetheless had its benefits as it allowed the Me-262 to have tremendously strong wings able to cope with VERY high G-forces.
