+Olham Posted August 23, 2012 Posted August 23, 2012 A "Fahrtmesser" on an aeroplane should be an "airspeed indicator". A "Tachometer" shows you the speed of your vehicle, independent from the RPM. You could drive 50 km/h at very different RPMs, right? While the RPM indicator does exactly that - tells you the rounds per minute. If you do not see the difference between these two, then you are hopeless cases.
HumanDrone Posted August 23, 2012 Posted August 23, 2012 I absolutely object, Herr Olham! We can see the difference and still be hopeless cases!
HumanDrone Posted August 24, 2012 Posted August 24, 2012 (edited) You know, these are some beautiful old instruments. And it's amazing what they did with them. I recall working for several days on a fancy computer analysis (when I was new at this), only to have my boss review my work and utterly demolish it in two minutes - with a plastic 6" slide rule! I just got a Droid Razr Maxx as my new company phone the other day. Of course, I immediately downloaded a slide rule for it! Thanks for the purr-ty pictures! Edited August 24, 2012 by HumanDrone
von Baur Posted August 26, 2012 Posted August 26, 2012 PS: there are other pages with more instruments in that site - really good quality pictures; like this "Barograph". Target Ware's "Richtofen's Skies" had this modelled (working) in one of their German two-seaters.
Dimus Posted August 29, 2012 Posted August 29, 2012 Another crude vintage airspeed indicator. The amazing fact is that it comes from a more modern interwar DH Gipsy Moth. You would expect a proper Pitot driven gauge by that time but perhaps it was charged extra, this being a civil plane.
+Hasse Wind Posted August 29, 2012 Posted August 29, 2012 A simple and cheap device like that one must have been perfectly adequate for the Moth.
Bullethead Posted August 30, 2012 Posted August 30, 2012 Yes, the Gypsey Moth's version was a simplified version of the Austrian Teddybär type ;)
