The power draw will increase twice as fast as you increase the solarcells.


Can you show me the calculations at 45 000 meters altitude for this with a 14 m dia propeller ( 10 x 4,5 m long blades in Gallaudet style around the fuse per propeller ) as shown in my drawings with a plane having 1/80th of the wingloading of a X-15 ?

Because 400 % or 1600 % just isn't science.

Look for the Panzer Holz in the web/google as it is a further developed Duramold ( by Clark and Hughes ).

Could be used in this as it much harder than aluminium and half as heavy.

Intention is to make a good climber like this ( sorta ).

These only have L/D of 3-5 but climb like anything.

F1D planes ( rubberband ) just have a 10-12 grams / m2 wing loaging...solar powered crafts generally have 1000 times more but 50 times less than jet aircarft.

Here is KIKI and Pterodactyl flying; https://www.youtube.com/watch?v=UXbj_4z52sE

This has a hypersonic nose cone; https://www.youtube.com/watch?v=mWqGVQyXQiU

Idiom ahoy !

I was able to make SOLAR EAGLE produce 900% times more power with Lithium Ion accus for a brief period. Should do it.

:wink:

rgds,

I developed a "green" fighter aircraft that could be carried on board the Solar Eagle mother plane.

I get easily delta -v for the prop/rocket aeroplane of equivalent of Mach 6.

How fast from 15 km at mach 0.9 speed could it actually go at 100 000 meters when rockets are turned on ?

Anyone wanna see a model of this flying ?

:wink:


I added some span to it.

I got a lot better wetted aspect ratio.

Calculations are for you to do :)

But each time the speed of the blades double, the drag quadruples. That is only considering the drag, not any of the other square-law problems.

The aerodynamic drag will be on the aircraft will be immense.

How much weight did the lithium Ion batteries add to create 900% additional power? How much did that slow the plane down? How long can they add power for?

The power depends how much you use it...does it not ? At least it will have 6500 kW for an hour. The weight has gone up...and I have shrunk the plane as well. So the initial weight is no longer 1/80 of the X-15 but rather 1/10th of a 747.

I have chosen to use several systems that have been introduced in aviation before but forgotten to enhance the efficiency and I can prove it works.

Plane is 15% more efficient carrier than HK-1 with 17 m more span. But since it is also 1/3 of its weight ( HK-1 was really lite ) it will climb a lot higher..unfortunately solar power plays just a minor role in this now. Vincent Burnelli stated that his lifting body designs have 50% more lift than similarly spanned regular crafts..it is possibly correct..because the WARE calculations don't show the increased lift by various other variables..like bigger Reynolds number, cleaner aerodynamics ( CFD ) and forward sweep etc.

Aeroplane that will dominate space in future for commercial purpose and exploration of space age. :) :) :) :)

Astronautdoc-1...I just merely tought that in order to fly higher you have to find out all the means possible to enhance the efficiency. I even invented a formula to better scope all possible variations...I call it the WARE number. It is just the old wetted aspect ratio multiplied with the lifting area...because wetted area can also be harmful if it is useless. The new number is both qualitative and quantitative. P-51H has around 39 and my small fighter inside SE 32...and He-162 "Volksjager" around 14 ( no wonder it sank like a brick after engine out ).

See by increasing the area and the span I was able to have almost 3/7th more lifting capability in an aircraft about similarly spanned as the Spruce Goose.

This can produce now with the enermous prop thrust using 8 000 kw for an hour...and unlimited time 600-700 kw from the sun.

In re-entry the STAR EAGLE is just 15 000 kg weighing shell...with 3 times more lifting area than space shuttle typically was 100 000 kg when landing. Shuttles started to glow red in 78-48 km and Star Eagle starts braking already at 150 000 meters and brakes to 6-7 000 km/h by 90 km altitude and thus can be without the tiles as it doesn heat up more than 300-400 C. Gasses around it may be 1000-1500 C.

Note the propeller size to HK-1 propellers.

700 watts doesn't sound like much but it is 3 times more power to weight ratio ( and just 100 times more brute power ) than what SOLAR IMPULSE had to stay airborne at nights.

Here is another 80 km reaching hybrid design. Looks a bit like a NAVI people making ( Avatar anyone ?).

:mrgreen:

A spaceflight no longer need manual assumptions and investigations than having a technical cosideration for its survival and reuse.
