ETS ISS evacuation Shuttle BETA
Prometheus

For orbiter 2006 P1 & 2010 P1

Overview:
ETS Prometheus is a small reusable spaceplane designed as emeregency crew crew
evacuation system for ISS, but can be also used as relativelly cheap alternative to ferry crew to
and from space station. It can carry up to six people (pilot, co-pilot & up to 4 passengers).
It can support crew for 4 days and can land on any major airport with 4 km runway. Craft
is equipeed with APAS docking port located on top beneath the cover.

That's a promising small shuttle. :thumbup: A few suggestions :

- add a pair of rcs thrusters in the "retro" direction. The ship doesn't brake very well.
- the rotational rcs thrusters are maybe a little overpowerful.
- the cockpit looks great, but IMHO the windows are too big.
- some decals on the texture

 

[HAL9001]

Awesome!
This shttle is just :thumbup: awesome!

 

[Loru]

Things currently being work on:

- RCS tweaks
- Flightmodel tweaks (current version acts as a brick)
- 2006 compatibility
- Crew managment within simulation
- Working rudder
- Speedbrake (using rudder)
- Chute for runway braking
- Minor bugs and issues

Hey! Don't forget the belly landing support :lol:

 

[Ricovandijk]

Nice addon! Just one question. after de-orbit and landing at KSC I am not able to 'kick-out' my mmu.

the alt-num key combi is not working.

sugestions/request:
- re-entry textures :thumbup:
- a square landing chute (like a big parasail to create extra lift for final approach)

Try looking under the shuttle - currently they appear inside a craft. That thing is being currently fixed

Very nice little shuttle,Loru looking foward to the new features.Thanks,and keep up the great work.:tiphat:

 

[Loru]

Ready for reentry


Developement update:

Almost all things are done

Working on a problem with trim (if engaged shuttle cannot perform 50 deg AOA reentry with Aerobrake MFD autopilot) - adding feature to disable trim during reentry

---------- Post added 05-05-11 at 11:29 AM ---------- Previous post was 05-04-11 at 10:16 PM ----------

Developement update:

2 almost identical crafts, one without trim and second with trim and during reentry first acts great and stable (AOA 57, 3.8 max G) and second is unable to hold AOA and drops nose at 77km and 7.2 km/s and wobles from left to right like drunk :/ Any ideas why?

Performed with Aerobrake MFD hold AOA autopilot. If unable to deal with problem, trim function will be permanently disabled (craft can perform well in the atmosphere and it's capable of gliding and landing without using of trim).

What about the Merlin IC for your second stage ? It's a little under your 500kN requirement, but else it has an ISP(vac) of 342s :

[Loru]

Yes - that's nice choice.

It gives me 0.7G to 2G acceleration of the second stage so I think it is in the acceptable parameters. Also it's only ~635kg.

Going to velcro to test the rig it inflight.

Nice choice of engine, why not use the entire Falcon 9?

 

[Loru]

Nice choice of engine, why not use the entire Falcon 9?

Because it's LEO capability is 3 ton short

 

[Capt_hensley]

How to make up 6000 lbs? Yeah that's a tough line to cross with F9.

Nice add-on! Keep up the great work

Developement update:

Aerodynamic model is working. Reentry with peak 2.7 G at 55deg AoA

Here are few shots:

- Gotta have some hot stuff - entry interface

- supersonic high altitude glide

- deeper into air

Beta 0.9 out. Feel free to download.

 

[Woo482]

It was a pleasure working on it with you Loru! really fun ship to develop and fly

 

[Loru]

Same here. :thumbup:

Now the launcher time - probably tommorow I'll get all meshes done

 

[jedimaster1214]

Very nice shuttle!
Small yet versatile. :thumbup:

but whatever happened to this? ---> http://www.lorusik.webpark.pl/vp3.jpg

is that saved for a later version, or just scrapped? or is it still being worked on?

 

[N_Molson]

oooh that's a pretty panel !

Panel is from another craft - MTS which is currently on hold, but will be released as soon as it's ready
