Title: Long March-11 first launch - Jiuquan - September 25, 2015 (01:41 UTC)
Post by: ChileVerde on 03/02/2013 12:41 PM
Very fast development timeline -- I wouldn't be surprised if CZ-11 turns out to be a modification of an existing missile.

China's first solid-fuel rocket to debut before 2016: official
English.news.cn   
2013-03-02 11:03:34    

BEIJING, March 2 (Xinhua) -- China's first solid-fuel rocket Long March-11 is expected to make its first launch before 2016, a senior official of the rocket's designing institute said on Saturday.

Liang Xiaohong, deputy head of the China Academy of Launch Vehicle Technology, said the rocket will be easy to operate and cost-efficient to launch. It can remain in storage for long period and reliably launch on short notice.

"The development of the Long March-11 will greatly improve China's capabilities to rapidly enter the space and meet the emergency launching demand in case of disasters and emergencies," he told Xinhua.

The Long March-11 rocket system consists of a solid-fuel rocket and a launching support system. It will apply China's largest solid-fuel rocket engine, he said.

China has made more than 160 launching of liquid-fuel rockets successfully but is yet to make breakthrough on the development of the solid-fuel rockets.

They are forgetting the KT-1 launch vehicle.

Speaking of that, could you recommend any good summary of what is known and speculated about the KT-1?  I tried to follow it for a while, but came away very confused.

Bumping this thread as the Chinese apparently is going to sneak in this rocket's first flight late this month (info is from ham radio operators who have payloads on this flight (http://forum.nasaspaceflight.com/index.php?topic=5060.msg1422031#msg1422031))!  :o

The payload will apparently be 3 ham radio mini-satellites. I wonder which 3 will they be?  :-X

It looks like that they might be TW-1A/B/C from CAS' Shanghai Micro-satellite Engineering Center. Previous reports stated that their planned orbit is a 481 km altitude SSO.

If CZ-11 will be really launched from Jiuquan, can it be from one of two Kuaizhou launch pads?

Dear Editor:
   I am the leader of the R&D team of cube satellite in the Shanghai Engineering Center for Microsatellites. I read the news report “SECM-1 Mission in Shanghai Engineering Center for Microsatellites: SkyNet No. 1 ABC satellite triplet” on your website in September 19th. Because of the content and unknown resource, I write this e-mail and hope that you will withdraw the report. Our main concern:

1.   While the report is about the research activities of our team, members of our team and the engineer center have never been contacted/interviewed.
2.   Part of the report will make bad influence and damage the public image of the engineer center.

Therefore, we hope that you can withdraw the report to avoid further damage. We will reserve the right to take legal action. Any report about us should ask our agreement first.

Shu-Fang Wu

Not a very precise translation. But you got the point.

I was worrying that with zero information around that this launch might have slipped....but nope!

So launch would be at around 01:45 UTC.

This prediction has been confirmed by one Weibo account (whose owner has provided good info on the final ramp up of LM-6's first flight last week), though he said there will be 4, not 3 satellites on board.  ;)

The fourth payload is not really unexpected, as the rocket reportedly has a performance of ~1000 kg to LEO and the three cubesats would use only a tiny fraction of this. So at least a larger dummy payload should be on board.

Looks like some reporter tweeted on Weibo that it has successfully launched......before it could have happened! That tweet has now disappeared into deep space so yes, it's a false alarm.  :-X

The real launch should come in about 30 minutes.  ;)

My attempt at understanding this article, mostly via google translate, suggests 6 satellites:

"and four other small satellites"   (TW-1ABC plus one other I imagine?)

About Pujiang-1:

- Small satellite to test various miniaturized satellite components (heat transfer pumps, microprocessors etc.)
- Utilizes standardized "plug-n-play" payload interfaces to able to carry wide range of instruments on board
- Have temperature sensors on board that uses WiFi to transmit data within the satellite
- Titanium antenna structure on the satellite was 3D-printed
- Was once planned to launch on the first LM-6 (http://scitech.people.com.cn/n/2015/0925/c1007-27634346.html) and the satellite even participated in the LM-6 GTV tests in November 2013 (before the 20 satellites mission ended up as its first flight). Later participated in the LM-11 GTV tests in July 2014.

E could be CZ-11 upper stage

Speaking of the CZ-11 4th stage....it looks like official reports are saying that (http://www.spacechina.com/n25/n144/n206/n216/c1039930/content.html) it is a solid stage as well (specifically derived from GSO satellite apogee kick motors).

The low perigee of E suggests that it also carries a liquid RCS system used for the disposal burn, at about 0153 UTC
The article I saw was comparing the launch technique (stage 1-3 sending stack to elliptical orbit, then coast to apogee
for stage 4 burn) to the GTO apogee kick motor technique. Can you point me to the bit where it's saying that the
actual hardware is derived from apogee motors?

I saw reports with three stage solid with YF-50 powered orbital stage for maneuvering.
Certainly looks like Epsilon and Vega have 'fierce competition' now ..

Yes, that was already mentioned on the NSF article about the launch.

Is CZ-11 based on DF-31 or DF-41, or something else? Is it related to the Kuaizhou launch vehicle in any way?

It's 2m in diameter, so it appears not. DF-31 and -41 are 1.7m, and Kuaizhou is 1.4m.

I've seen a variety of claims for the diameter of DF-31/41: 1.7m, 2.0m, 2.25m as well as disagreement on whether the DF-41 and DF-31 have the same diameter or not.
What do you think is an authoritative source for the DF-31 and DF-41 diameters?

And the 2m diameter quoted for CZ-11 might be including some slop.

So I don't think we can rule out the identity, and my guess is that in fact CZ-11's lower stages are taken with minor mods
from DF-31 or 41, given the short development time and the fact that the diameter *might* be the same

I'm just going off what Norbert Brügge has, but I don't see anything further on his site about where those figures are sourced from, or how he derived them if he came up with them himself.

The DF-31 transporter erector launch tube has some similarities to the launch tube used by CZ-11.  The transporter itself is different and, of course, DF-31 only has three stages (reportedly).  The comparison becomes better if the CZ-11 image is stretched horizontally to a 4:3 format.

Another video here, hot fire test and more complete animation. They show whats clearly a liquid engine which i'm assuming is the upper stage YF-50, but just guessing

That looks way too big to be an upper stage engine for a vehicle this size. Here's the payload fairing separation.

That looks to me like the totally unrelated YF-100. Which I guess an ENG editor might mix in the reel just because he had it. Specially if he was covering the LM-6 launch, too.

So, does anyone know about this GAMANET protocol?  I have some S-Band stuff that should be able to pick it up.  But once it's picked up, I need to know how to process it into something meaningful  :D

I guess you'd need the exact spec, which doesnt seem to be open, but

The last simulated launch shown on the video was a CZ-6.  The other simulated launches looked like CZ-11.  There were also a couple of bits showing liquid engines or stages, but the opening test firing looked like a CZ-11 (DF-31?) solid motor first stage.  Similarities to Castor 120.

It seems like a good idea to post some shots of the 1st launch of the CZ-11 on the day the 2nd flies. These have been just dug up (http://m.weibo.cn/1144250793/EgN78wr4X) by one of the mods of that Chinese forum I visit frequently. ;)

Images from a ground test of the CZ-11 show the designation WROII at the payload fairing. What does it mean? Maybe "II" stands for "11" but I have no idea for WRO.

Looks like there is a base charge to eject it from the canister, followed by ignition of the first stage motor at an altitude of about 10m.
