Thanks!

[...] if you authorize me to use them to accompany the cutaway.

I'd forgotten to answer you, but yes, feel free to use them! As long as proper credits are given, I have no issue with the use of any of my pictures (unless they're used commercially, that is).

Here's a little turn into the Luft 46 realm, a Daimler-Benz Jäger. I've no idea about its technical feasibility, nor if it was even a real project at all, but I really liked the idea of mid mounted propellers.

Propulsion / Re: Gas Turbine Development Question
« Last post by charleybarley on Yesterday at 05:29:42 pm »
For an Olympus 301 at take off (ref The Avro Type 698 Vulcan by David Fildes p.345) gas leaves combuster at 500 ft/sec and enters stationary part of turbine ie nozzle guide vanes. It leaves nozzles at 2065 ft/s and heads towards moving part of turbine ie blades which are moving away from it at high speed. So gas 'hits'  moving blades at some lesser speed, for example if blades are moving at 1500 ft/s the speed of gas relative to blades may be something like 1000 ft/s.

Third stage. Bottom two pics show how the fairing opens up for the lander to appear inside.

This set is of one of the tiny figures that comes with it. Not totally like the real figure but correct scale.
