One tester to test spec of DGIV ?

[DanSteph]

I was thinking to add a "technical data" page to the doc with "3 view blueprint" and technical specification, like max
speed, take-off distance, comsumption for a given engine and setting, max lift off capacity with hover, max speed at  
given altitude etc etc a bit like technical page in manual of aircrafts.

Nothing to complex anyway but if someone can make
the test and collect the numbers I'll put them in the doc
(and would be gratteful

One may have a look at technical data of real aircraft or shuttle maybe to get the idea ?

I have Visio (which could be used to give it the "blueprint" look) and a PDF conversion tool on my work laptop.  I
would be able to convert the entire doc into PDF if needed.  

Also, Dan, if you had a wireframe image of the DGIV, maybe use that for the 3D blueprint view?  If you could get the
views to me, I could put them in the document, along with measurements (wingspan, length, height, etc.)

Let me know if I can help.

I've played around with enough performance charts, I could probably work up all the V-speeds, Take off and Landing
distances, and such for you. Best climb might be sort of silly, seeing as how it can climb on its tail anyways... But I am
not a beta tester. If you wanted to wait til after gold beta, I suppose I could do it.

Hello I can make the blueprint as well as converting to pdf, only things that I would need (and that may be time
consuming) are the technicall data, they require some test and some time.

Cheers

First image, adapation will be made in function of doc size and type (I think pdf with intro in html)

Nice blueprint, but the frontview is a tangled mess because of all the stuff front to back, in other words, accurate because
it would look like a tangled mess if someone wireframe x-rayed the front

[DanSteph]

I preffer the front view as other view have irrealistic empty space.
One would things that a x-ray view of such aircraft would be almsot all dark
due to all system, the side view show about none of them.

Hi Dan I just read the topic if I'm not already late I will be happy to do the tests and report all the numbers :bug

Hi Dan,

I'm not sure if my post about this topic already reached you, but in case not, I can provide you an example of
technical specification data from a flight manual I'm writing as my job. I would like also to enforce the presence of a
nice checklist, real aeronautical style in order to put an emergency backup inside the cockpit of the deltaglider.

Could it be a nice idea for you?

Cheers

Whaaahhhh , tu as trouvé un blueprint !
Super, tu pourrais en faire un modèle 3D !
Regarde dans création, y'a un tuto pour ça si tu as du mal !

[DanSteph]

Thanks for offer, I think I'll start this with the doc, I'll add only some basic spec
(speed, power etc etc) later at correction if peoples have more data we can add it
without problem.

Will even be more simple with a practical example.

Hi Dan,
I did some flight tests for performance data,
my tests were specific for atmosphere aerodynamics (it's my job).
All tests were performed only in earth atmosphere but if it's useful I can test other planets also.
All tests were performed with default DGIV settings even if higher settings affect only fuel & oxi consumpition so they
do not affect spacecraft mass.
Here are the data so far:

-STALL SPEEDS-
-MAX WEIGHT (full fuel and payload)
 -MAIN ENGINE IDLE/STOP - 82 m/s
 -MAIN ENGINE ASSISTED  - 73 m/s

-MIN WEIGHT (10% main fuel -10% rcs fuel -100% lox -no payload)
 -MAIN ENGINE IDLE/STOP - 60 m/s
 -MAIN ENGINE ASSISTED  - 58 m/s

-BEST GLIDE AT 5°AOA (with reentry autopilot assist)
 - give about:
  -135 m/s (depending on altitude)
  -39.5 km range from 10000m to ground

DAMAGING SPEEDS (doors open)
-RADIATOR               40m/S
-ANTENNA&CARGO DOORS    50m/s
-TURBOPACK DOORS&CANOPY 52m/s
-HOVER DOORS           340m/s (760°max temp.)

All test were done with airfoil only control (aircraft style).
If you need any more tests I did not think about just let me know
I'll be happy to help.

You probably need an altitude for those damaging speeds. I assume about sea level.

[Murdock]

No, you don't need any altitude,
what you need to know (I forgot to specify)
is that all speed are IAS so they are pretty much independent from altitude.
Of course some damaging speeds were tested on ground since they are below stall speed

[Murdock]

Hi Dan,
I don't know if you had some time to have a look at the performance data I posted,
I hope they were helpful, probably they are not complete, if you can give me direction on other tests
that might be needed I'l be happy to help.
