wrote: In Martin Gregorie's post I noted the adaptation of a variometer originally used in Zeppelins. Pass. All I know is what Simons says: "The origins of the device went back to nineteenth century ballooning. Lippisch had used one when working with Dornier on Zeppelins. It had not been realised till now that soaring pilots needed such a thing.". This was in the context of a paragraph about the introduction of the vario, why it wasn't needed for ridge soaring and why it was needed for thermalling at altitude over flat land. Was this the first vario for gliders? Simons thinks so. Reading between the lines he also thinks that the involvement of Lippisch, who was hired as a designer for the RRG Research Institute in Darmstadt, provided the link between airship instrumentation and gliding. I'm assuming the original development of varios for ridged airships was to give the crew rising and falling airmass readouts so that they could correctly trim and shift ballast to keep the ship relatively stable. That seems very likely. -- martin@ : Martin Gregorie gregorie : Harlow, UK demon : co : Zappa fan & glider pilot uk : |
