There doesn't seem to be one at the Hangar. The v1.11 Velcro has been compiled for Orbiter 2010. Also N_Molson's DG-Launcher has these additional required addons:

- DeltaGlider IV (by Dansteph)
- UGCO (by Dansteph)
which both work only in Orbiter 2010. (At least the versions that are on Dan's page.)

Thanks for the info. After some extensive net surfing I found the pre-2010 version of velcro rockets (1.10) and it works perfectly, even with the europe DG launcher from n_molson. Perhaps I'll post a pic of the Ravenstar with the europe boosters lifting off from pad 12 (as soon as I retexture the default pad).

:cheers:

Am curious tho, how do you change the velcro rockets autopilot target altitude ?

Payatch does get saved?

Using a Velcro 3 stg rocket to place to payloads in orbit I use Seriesburn for the first and payatch for the secoend. However when a scenario is saved (quicksave or saved via the miss.edit) the payatch line that was in the original scenario and was the current attachement state for the second paylod doesnt get saved.
On top of that... if you edit the saved scenario file appending the payatch line for the stage in question... It does get attached...but when jettisoned the second payload exhibits a strange bevavior ("instant" rotation to a diff. attitude and position). It is as if the position of the payatch payload doesnt get updated with current position and orientation at time of jettison.
Can anyone confirm this?

--- edited ---
I can see in the velcro manual under "other .scn oprions:" that the configuration entry only has two states - either payload jettison or payload on... What if you have jettisoned first(seriesburn) payload and not the second(payatch) payload

Working on a lunar lander project where the hover engine is the main landing engine. I was adding a velcro droptank using the "crossfeed" statement. It appears that if the engine drawing from the tank that the velcro tank crossfeeds to is a hover engine then velcro will not crossfeed. Tried the "DG with two dropstanks" scenario that comes with Velcro 1.1 and confirmed this behavior.
----- Edit-----
Think I cracked it.
If the vessel in question is a Spacecraft3 vessel then make sure to add a "MAIN_THRUST=xxx" line in the config file. XXX doesn't have to be a great value if you dont plan to use main engine. Before entering the scenario.. make sure that the fueltank you need to draw from (that the velcro tanks crossfeed to) is filled up (scenario file says PRPLEVEL X:1.00000 where X is the tank you crossfeed to). After starting the scenario...before using the hover engine...engage the main engine shortly and verify that fuel is drawn from the right tank (Refuel MFD is helper).
This procedure helped me.

Abnormal spinrate at jettison using seriesburn

Upon jettison I have experienced the vessel being jettisoned receives an extreme pitch, roll and yaw rate. I'm using seriesburn statement of a third-stage Velcro vessel that carries another vessel that is - after TLI - supposed to be gently jettisoned and then be on its own.

However as mentioned is immediately develops and uncontrollable spinrate

I have tried various Velcro options as per the Velcro manual but the only one that seems to have an effect is spintable whereby it gets a small amount of rate around the X-axis that I can recover from. But still far from desirable. How does spintable command works...is it a vector or can a spin only be applied in one direction. if I set spintable to 0.01 is seems as if the spintable option is ignored?

Anybody else with experience in this area or ideas to share

Best regards
Michael

Velcro.dll rebuild

To get some Boosters flying i just tried to rebuild Velcro - from sources provided in the distribution - in orbiter2016 Environment.
Set references to cvellib and OrbiterSoundSDK40.

But the Compiler kept complaining about some "guidance.h" not found.
Does anyone know, what library is missing here?

Thanks in advance :tiphat:

I suspect that there will be big issues with the touchdown points in Orbiter 2016 anyway.

quick-and-dirty patch for 2016

With permission from sputnik i hand this one to the commnity.

Because for getting into fligth and explore Orbiter2016's beautiful new landscapes, i needed a rocket :shifty:.

Plain Installation of Velcro-Rockets in orbiter2016 left those rockets non functional.

I could build Velcro.dll with vc++2010, but had to recompile cvel.lib first.
Refs to orbitersound40 must also be set for build.

After that i could start an example Scenario and the rocket showed up at the launchpad but tipped over right at engine ignition - as expected.

After adding:
Code:
void VELCRO::LoadState(  FILEHANDLE scn, void *vs )
{
...
	static const DWORD ntdvtx = 4;

	if (padbias != 0.0) {
		VECTOR3 currTD1, currTD2, currTD3, [COLOR="Lime"]currTD4[/COLOR];
		GetTouchdownPoints(currTD1, currTD2, currTD3);
		[COLOR="Red"]//SetTouchdownPoints(_V(currTD1.x,currTD1.y,currTD1.z+padbias), _V(currTD2.x,currTD2.y,currTD2.z+padbias), _V(currTD3.x,currTD3.y,currTD3.z+padbias));
		currTD1 = _V(currTD1.x,currTD1.y,currTD1.z+padbias);
		currTD2 = _V(currTD2.x,currTD2.y,currTD2.z+padbias);
		currTD3 = _V(currTD3.x,currTD3.y,currTD3.z+padbias);
		currTD4 = _V(0,0,padbias+10.0);[/COLOR]

		[COLOR="lime"]static TOUCHDOWNVTX tdvtx[ntdvtx] = {
			{currTD1, 1e8, 1e6, 3, 1},
			{currTD2, 1e8, 1e6, 3, 1},
			{currTD3, 1e8, 1e6, 3, 1},
			{_V(0.0,0.0, 1.0), 1e8, 1e6, 3},
		};
		SetTouchdownPoints(tdvtx, ntdvtx);
	}
[/COLOR]
...
and
Code:
void VELCRO::SetAttachedStage( )
{

...

VECTOR3 currTD1, currTD2, currTD3, [COLOR="lime"]currTD4[/COLOR];
	GetTouchdownPoints(currTD1, currTD2, currTD3);
	if (PrimeBooster)
		[COLOR="Red"]//AtchV->SetTouchdownPoints (_V(currTD1.x,currTD1.y-0.01,currTD1.z-0.1-attach[chosenpoint].z+tgtpos.z+padbias), _V(currTD2.x,currTD2.y-0.01,currTD2.z-0.1-attach[chosenpoint].z+tgtpos.z+padbias), _V(currTD3.x,currTD3.y-0.01,currTD3.z-0.1-attach[chosenpoint].z+tgtpos.z+padbias));
[/COLOR]
		[COLOR="Lime"]currTD1 = _V(currTD1.x,currTD1.y-0.01,currTD1.z-0.1-attach[chosenpoint].z+tgtpos.z+padbias);
		currTD2 = _V(currTD2.x,currTD2.y-0.01,currTD2.z-0.1-attach[chosenpoint].z+tgtpos.z+padbias);
		currTD3 = _V(currTD3.x,currTD3.y-0.01,currTD3.z-0.1-attach[chosenpoint].z+tgtpos.z+padbias);
		currTD4 = _V(0,0,-0.1-attach[chosenpoint].z+tgtpos.z+padbias+10.0);

		static const DWORD ntdvtx0 = 4;
		static TOUCHDOWNVTX tdvtx0[ntdvtx0] = {
			{currTD1, 1e8, 1e6, 3, 1},
			{currTD2, 1e8, 1e6, 3, 1},
			{currTD3, 1e8, 1e6, 3, 1},
			{_V(0.0,0.0, 1.0), 1e8, 1e6, 3},
		};
		AtchV->SetTouchdownPoints(tdvtx0, ntdvtx0);

...

similar,
the rocket was able to Launch after some trying with the material stiffness-param (1e8).


But the (stage).cfg's (in Config\Vessels\Velcro\*.cfg) have also to be edited, since the weight has to be loaded in equal parts on the first three touchdown-points or the rocked would not stand upright due to finite stiffnes of the ground. Defining These Point as an equal sided triangle, the z-axis right through the Center works.

example: AtlasVCore.cfg
Code:
; === Configuration file for vessel class Generic CVEL stage (Atlas V Core) ===

Meshname = Velcro/EELV/AtlasVCore
Size = 14.0

Mass = 22461 ; empty mass [kg]

Isp = 3319        ; fuel specific impulse [m/s]
IspSL = 3050.9

MaxMainThrust = 4153416.66
MaxRetroThrust = 0
MaxHoverThrust = 0
MaxAttitudeThrust = 12778
COG_OverGround = 4.0
CameraOffset = 0.0 0.0 17.0
CW = .2 .3 .7 .7
LiftFactor = 0.0
CrossSections = 30.0 30.0 16.0
RotResistance = 0.7 0.7 0.3
[COLOR="Lime"]Touchdownpoints = 0 4.4 -16.778  3.81 -2.2 -16.778  -3.81 -2.2 -16.778[/COLOR]

Giving a constant for touchdownpoint[3] is not a clean solution at all :facepalm:, i'm working on appropiate params in the (Vessel.cfg), maybe a

Anyway the patch worked for me. Let's name it ...
