Hi Mark, you are right, the static destabilising moment is higher for more slender bodies! In Munks theory, the static moment M is M=q*V*(kz-kx)*sin(2*alpha) ...
... That _always_ bothers me. But back in the '20s Charles Burgess thought it was obvious that a more slender ship was easier to ground-handle too. I guess...
... Hello, I have forgotten some of the rules and the various ways to earn points, but it sounds like speed is a key design driver. The evolution of the...
The victor's advantage is mostly having the finest LTA experts around. The art is to integrate all the knowledge and experience into a buildable and ...
Until someone enlightens me otherwise, I'm assuming the Kugelblitz entry took advantage of the structural efficiency offered by the sphere to devote extra...
... Considering the fact that the usual fusiform models are operating in a range of lower Reynolds numbers - in other words with a higher friction coefficient,...

Considering the structural efficiencies possible, a mere factor of three seems pretty low! Definitely worth considering even for long range missions I would...
... Attached is a diagram of the semi-cubic drag coefficients as a function of the slenderness ratio. These coefficients (denoted as squares) are derived from...

... Yahoo censors those things out. However from what you write it does not seem there are any surprises there. The argument I was replying to is that at big...
In regard to addressing the large pressure drag of a sphere Juergen Bock ... I think C.P. Burgess wrote strongly against that strategy in his chapter on ...
http://www.me.umn.edu/~hork0004/experimentsinfluids/ Some of the flow visualization pictures were intentionally left out by me as they were of poor quality....
... Thanks for summarizing the fields of useful application of spherical airships. It looks like this discussion is blowing up to a full size seminar, which I...

Hi airskippers, what do you think of a second RC Airship Regatta? Michael Kuntschik and me are discussing a Race in Flensburg, end of October. To give more...
Hallo Luftschiffer, als erstes möchte ich mich dafür entschuldigen, dass ich deutsch schreibe, mir ist das übersetzten jetz aber einfach zu viel Arbeit. Ich...
Hi all, Rainer suggested in his e-mail to make use of the fact that airships can be flown in 3 dimensions and that the race course for the second race be...
Hello all, the last race had about 6 participants. Most of them from nearby locations. The racer itself is a rather expensive undertaking, if you are not...
Fellow AirShipper, the 2nd International -hopefully ;)- RC-Airship Regatta will take place in the beautiful town of Flensburg on Sunday, October 24th. This...
Fellow LTA-enthusiasts, here are the latest news concerning the planned "Eckener Memorial Regatta" in Flensburg. As I have announced some time ago, this race...
Philip brought in the thought, that a smaller ship would have to master a relatively longer distance, when the parcour is kept the same. So I reworked the...

Hi Andy, if you really want to build an RC blimp: First of all: "read the books", as some of my former colleagues use to say. Well if you don't have have such...
