MiloMorai Posted December 5, 2013 Posted December 5, 2013 Stern, he is talking about the mythical 1,98ata K-4. Like every other aspect of aircraft maintenance, the type specific maintenance manual will list the propeller adjustment for wheel alignment. Propeller adjustment to adjust the wheels???
Sternjaeger Posted December 5, 2013 Posted December 5, 2013 (edited) Thank you. I meant the Bf 109 variants article. The relevant section says: "The Rate of climb was 2,775 ft (850 m)/min.[101]" Two more questions if I may. 1. Do you think the above figure is anywhere near correct? 2. Do you know who made this edit and to what purpose? well I dunno what wikipedia page you're looking at pal, but it doesn't say that here http://en.wikipedia.org/wiki/Messerschmitt_Bf_109 are you sure you're not on noncyclopedia? EDIT: Ha! Found it, it's under 109 variants. Well it's in the Boeing 737 realm.. a bit frisky eh? In any case...so? Why should I care? Edited December 5, 2013 by Sternjaeger
DD_bongodriver Posted December 5, 2013 Posted December 5, 2013 The 109K climb rate has nothing to do with the topic of the 109's well documented directional instability.
Crump Posted December 5, 2013 Posted December 5, 2013 When the aeroplane is rolling with an equal download on both wheels, symmetry prevails; both wheels fight to a stand-off, and the aeroplane rolls straight. With the aeroplane’s centre of gravity situated high above the tires, a swerve will set loose large centrifugal forces that cause the aeroplane to try to roll over the tires. This is true of any aeroplane That is the important stuff in the quoted text. The rest is just word filler. Camber is an issue for all early oleo equipped tail draggers. None of them changed camber as the oleo compressed and that will lead to handling issues. The gear are spayed out on the Bf-109 to reduce the oleo travel and soften the suspension.
JtD Posted December 5, 2013 Posted December 5, 2013 Another 109 landing gear debate going south with personal and off topic stuff. Frigging annoying.

This is true of any aeroplane Don't forget to include the important pieces of information when you quote, remember this is not about 'any' aeroplane but is about the 109's directional instability. Here is the important and selectively omitted part of the quote. but in this scenario the unusual camber of the Bf-109’s tires creates strong directional instability.
Rama Posted December 5, 2013 Posted December 5, 2013 Another 109 landing gear debate going south with personal and off topic stuff. Frigging annoying. Yes, and another one I have to lock (not time to waste to remove personnal and off topic stuff. ... to all involved, in next "debate", all personal and off topic stuff will procure a direct ticket to banville.
