Propulsion / Re: DB021 turboprop
« Last post by NUSNA_Moebius on Yesterday at 06:32:54 pm »
my thought was to convert an Fw190D over to a possible turboprop version, which got me to thinking if there ever was such a proposal, or even a Ta152.

It is my dream to build or acquire an FW-190D replica and convert it to the most powerful turboprop that could fit, hopefully something in the 4000 HP range. 

A boy can dream......... ;D

Thanks martinbayer friend for the data review and got the name of the same Lippisch "Gleiter Bombenflugze", although it was not official history after the drafts found by the allies after the end of World War II indicate that at least sketches of the concept were made. Luft46 page does not appear in the index but it appears in the search engine ...!

Thank you friend Gray Havoc and complement the data and managed to locate the name of the Lippisch project "Gleiter Bombenflugze"

Here I leave the drawing with the identification and some tweaks ... Now to find the differences ... !!

Interesting to note the differences between the XF2R-1 as shown in your cutaway and the aircraft as actually built; that is, squared-off wing and fin tips, and NACA inlets for the jet engine.

cheers,

That's rubbish. Currently, the world is already full of products you can purchase, yet lots of people still enjoy making their own. Take my hobby for instance: I could buy premade diecast scale models, but instead I build models from kits or I scratchbuild because what I enjoy is the process of creating something.

Orionblamen- Regarding the artist.  There was an SF short story written 50+ years ago about an artist that worked with a voice-controlled 3d printer.  He created sculptures that were anti-gravity, but only when inebriated.

An interesting text, written by Reimar Horten, states that the Ho VII was supposed to be a test bed for the Schmitt-Argus pulse jet engine before the project was cancelled, and later fitted with conventional propulsion.

The H VII was conceived as a test bed for the Schmitt-Argus pulse jet engine. When this project was canceled, we were left with a trainer. We designed the aircraft in Gottingen, and built the wood en wings, while Peschke made the all metal center section.
 The two seats were arranged in tandem between the two 240 HP Argus engines, each driving a constant speed pusher propeller, with feathering capability. The retractable landing gear featured two main wheels, and two parallel nose wheels on separate struts...

I am curious to know how the pulse jet(s) would have been arranged on the Ho VII. My best guess is two pulse jets at the same locations of the Argue As 10s. What do you guys think?

I edited an existing drawing to illustrate my hypothesis, here's the result :

Not necessarily. When 3D printers/fabber/replicators can truly replace pretty much any other means of making something, the urge to create will still exist; it will just be expressed differently... via creating stuff on the computer. I've seen a lot of artists who "sculpt" some pretty amazing digital figures, and with modern and projected input devices, the techniques are actually not dissimilar from sculpting in clay. With augmented reality glasses and input gloves that feature sensory feedback, it will be a *lot* like physical sculpting... just with the ability to hit "undo."

And, sure, if the computers go down, there will be trouble. But if there's a massive EMP strike or a Carrington Event, we'll have bigger things to worry about than a lack of new spaceship model kits.

Yep.  The stuff they can do in ZBrush is pretty mind-blowing.

It was followed by another series of novels starting with 'Fighting Submarine' (1978) which followed a British submarine commander through the war.
