Question Interplanetary flight using XR-2 and XR-5?

[Luft2010]

Hello,

I just want to ask if its possible to do interplanetary flight using XR-2 and XR-5 with the help of InterMFD? I have been also trying to go to the moon using InterMFD using XR-5 but when I want to Orbit-Eject my plane to the required course it only says "No Escape information". I have tried using off-plane interception and Tangential Transfer.

I want to know what I'm doing wrong since I have been quite comfortable going to Venus and Mars with DG-IV.

Thank You for your kind help

P.S: I have just registered here and I'm sorry if there is any related tutorial or information that I have missed or unaware of.

How experienced are you at Orbiter?

How experienced are you at Orbiter?

Hm well so far, I have just started playing Orbiter for few months, made a couple of flight to the Moon, Mars and just recently to Venus using Interplanetary MFD. I grasped the basic idea of planetary transfer. I know how to put XR-5 and DG to orbit but so far I've not been able to master the re-entry.

I've actually tried entering once with XR-2, successfully entered the atmosphere without any damage but crashed near Indonesia because although the map said there's a base called Doberai there the base is not physically there and I have completely run out of fuel when I only saw sea. I hope I can learn this part also.

Firstly, i would suggest for Earth-Moon Flights you just use Align and Transfer MFD's. For Interplanetery flights i would read up on TransX MFD.

Secondly, the Doberai base is actually physically there, it looks like Brighton Beach on Earth. Perhaps you missed it :shrug:?

Yes but limited fuel and O2 reserves (esspecially on the xr2) make it quite difficult. You can tweek these by editing thier .cfg files but some would consider that cheating.

As for your "No Escape information" it sound to me like IMFD was not synced up. Sounds silly but go back and make sure that your escape and transfer stages are set to the proper reference bodies.

From my perspective I would not consider it "cheating" to change any of the normal (i.e., non-cheatcode) settings the XR preference files -- it's simply choosing what grade of [much more expensive] fuel you want to load into your XR. Of course YMMV, so if tweaking the fuel or LOX feels like cheating, that's fine, too.

In any case the short answer is if you want to do interplanetary flights you can load up extra fuel & LOX tanks into your XR2 or XR5 payload bay while still using the default ISP & LOX settings and/or you can edit these settings in your XR vessel's preference file (the XR2's settings are below):

#--------------------------------------------------------------------------
# Main Fuel ISP ("Specific Impulse") setting. This determines how much
# main/hover/rcs fuel is burned each second for a given thrust level.
# Higher settings allow longer flights without refueling. Remember to
# update the 'LOXLoadout' value later in this file as well so the crew will
# have enough oxygen for the mission!
#
# NOTE: The 'Expert' setting (0) is tuned so that you will need to use your SCRAM engines
# efficiently during ascent to LEO ("Low Earth Orbit").
# ISP values for each level are shown in [brackets].
# 0 = Expert (ISS Only w/expert use of SCRAM engines and expert deorbit/landing) [13943]
# 1 = Realistic (ISS Only) [20914]
# 2 = Default (ISS and Moon) [25962]
# 3 = Medium (ISS and Moon w/reserve) [32981]
# 4 = Stock DG (Moon w/large reserve; this is the original stock DG setting) [40000]
# 5 = Big (Mars) [52922]
# 6 = Huge (Jupiter+) [366251]
# 7 = Massive (Jupiter+ w/full payload) [476127]
#
# The default value is 2 (ISS and Moon).
#
# NOTE: You can override this global setting for a given scenario by setting a value for it in your scenario file;
# Refer to the scenario file named "Configuration File Override Example.scn" for an example.
#--------------------------------------------------------------------------
MainFuelISP=2

LOX loadout is:

#--------------------------------------------------------------------------
# LOX (Liquid Oxygen) loadout setting. This determines the maximum duration of a mission without
# replenishing the LOX tanks. Times listed assume a full crew (14 crew members); reducing the
# number of crew members will increase the maximum mission duration accordingly.
#
# Increasing this value will increase the LOX loaded into the ship. The mass value
# displayed for each setting assumes a LOXConsumptionRate (the parameter following this one)
# of 4 (realistic: 100% of normal). To reduce the LOX mass required for a long mission,
# leave LOXConsumptionRate set to its default value of -1 (AUTO), or set it it 0 (OFF) or 1 (very low).
#
# Valid options (duration assumes full crew of 14):
# 0 = 7 days ( 182 kg)
# 1 = 14 days ( 364 kg)
# 2 = one month ( 792 kg)
# 3 = three months ( 2374 kg)
# 4 = six months ( 4746 kg)
# 5 = one year ( 9489 kg)
# 6 = two years (18975 kg)
# 7 = three years (28462 kg)
# 8 = four years (37948 kg)
# 9 = five years (47438 kg)
#
# The default value is 1 (14 days).
#--------------------------------------------------------------------------
LOXLoadout=1

Or you can change the LOX consumption rate to account for your crew using the optional Altea Aerospace Cryogenic Pods:

#--------------------------------------------------------------------------
# LOX (Liquid Oxygen) consumption setting. This determines how much oxygen is consumed
# by the crew for a given length of time. This setting determines the LOX mass required for a
# given mission duration; i.e.,
#
# LOX mass loaded = LOXLoadout x LOXConsumptionRate
#
# WARNING: setting this value to other than 0 (AUTO) or 1 (very low) may result in a significant mass increase
# when LOXLoadout is set for a long mission duration (e.g., one year or longer).
#
# For example, with a LOXLoadout of 5 (one year), the actual LOX loaded would be:
# 4 (realistic) = 3389 kg (100% of normal)
# 3 (medium) = 2542 kg (75% of normal)
# 2 (low) = 1695 kg (50% of normal)
# 1 (very low) = 848 kg (25% of normal)
# 0 (OFF) = 100 kg (mass is fixed)
# -1 (AUTO) = 848 kg (varies between 100% and 12.5% of normal depending on LOXLoadout.)
#
# Valid options are:
# -1 = AUTO (Recommended; varies between 100% and 12.5% of normal depending on LOXLoadout.)
# 0 = NONE (oxygen consumption DISABLED)
# 1 = very low (25% of normal)
# 2 = low (50% of normal)
# 3 = medium (75% of normal)
# 4 = realistic (100% of normal)
#
# The default value is -1 (AUTO).
#
# NOTE: You can override this global setting for a given scenario by setting a value for it in your scenario file;
# Refer to the scenario file named "Configuration File Override Example.scn" for an example.

LOXConsumptionRate=-1

I can verify that IMFD works just fine with the XR series vessels - there must have been an error in your set-up of IMFD - possibilities that come to mind are MFD's not shared correctly, or you have set the Src wrong (should be planet you are leaving - not your vessel).

Delivered 20 TEUs to Olympus this very morning: 1 TMI in IMFD, 1 seat of the pants MCC by RCS with the help of IMFD Map mode. Aerobraking insertion, a very chaotic landing, the DG-01 sitting at Pad 3 must have been blown away.
