1/144 RealSpace Chinese
CZ-2F Launch Vehicle

By Tim Nelson

Background

 


Yang Liwei

The Chinese joined the Soviet Union/Russia and the United States as a spacefaring nation on 15 October, 2003 with the launch of “taikonaut” Yang Liwei on a one day earth orbital mission aboard Shenzhou 5. China’s second manned space mission, Shenzhou 6, was a successful 5 day mission launched on 12 October, 2005. This flight had a crew of two taikonauts, Fei Junlong and Nie Haisheng.

This spacecraft and its launch vehicle share many passing similarities with the Russian Soyuz, but they are not related. The CZ-2F launch vehicle is the latest, man-rated, version of the venerable Chang Zheng (Long March) series of rockets. This vehicle is the basis for China’s ambitious future plans for a long-term space station in low earth orbit, and a building block for eventual moon missions.

My interest in human spaceflight goes back to early childhood. I’ve previously built 1/144 models of every major type of manned launch vehicle , but that collection has been incomplete since the Shenzhou 5 mission. I set out to fill that hole with this model.

The Kit

Glenn Johnson’s RealSpace Models line of kits is the gold standard of factual space modeling. His CZ-2F kit is an all resin affair, consisting of approximately 28 parts. The parts are generally well cast, with only a couple of small bubbles. There are some small surface irregularities, particularly with the corrugated sections, which are easily corrected with a bit of time, patience, and riffler files. Some cleanup effort has to be devoted to the conical shroud segment on top, due to the many blisters and bumps on the prototype. The 8 rocket nozzles also need some cleanup, and you need to fabricate 8 small vernier or exhaust nozzles (not sure exactly what it is!) from tube styrene for the 4 core engine installations and each of the 4 strap-on boosters. None of this work is out of the ordinary for a limited run kit.

My only complaint about the engineering of the kit, and it is a minor one, is that the 4 stabilizer flaps on the shroud section are cast in resin. In my opinion, these flaps would be fine candidates for photo-etch treatment, which would look better and not require tedious cleanup. (The flaps serve the same purpose on the CZ-2F as the similar flaps do on the Russian Soyuz vehicle; they deploy out and downward to stabilize the shroud section (which contains the spacecraft and taikonauts) in a low altitude escape-tower-propelled abort scenario.)

The Build

Other than basic parts cleanup, the key to this build is alignment. The CZ-2F is a tall and skinny animal and you need to pay special attention to avoid a catty-wompus result. The core of the vehicle consists of 3 cylindrical parts which need have their mating surfaces absolutely flat and true. In addition, there are external wire tunnels which run most of the length of the vehicle on 2 sides and must be aligned at the joints. I had some trouble getting both sides simultaneously aligned, and chose to use the better side for the front of the vehicle. After much dry fitting, I joined the 3 core segments with 5 minute epoxy to allow sufficient working time for best placement.

There are holes on the sides of core section and each of the strap-on boosters to aid in placement. Small bits of wire are recommended for a strong joint. In addition, there are wire straps near the top of each strap-on booster which should be rendered with small diameter wire for an accurate look.

The RealSpace decals are first rate and go on with no problems. They work well with Microset and Microsol solutions. However, where you put them is a bit confusing. References on the Chinese manned space program in general, and the CZ-2F in particular, are sparse. CZ-2F photographs are difficult to assimilate because of conflicting information. The vehicles are basically white with blue trim, but individual mission markings vary. A particular point of confusion is the markings which run the length of the core section of the vehicle. Taking a top-down view, divide the vehicle into eighths, with one set of lines bisecting the strap-on boosters and another set of lines halfway in between. Some photos seem to show the core markings not aligned with any of these axes due to the position of the vertical wire tunnels. My decal placement was done in accordance with these photos, most or all of which I now believe are of unmanned test vehicles. However, the best photograph I have seen of the launch of Shenzhou 5 (which I unfortunately did not find until after I finished the model), seems to show all markings aligned halfway between the strap-on boosters. I will be redoing my decals accordingly in the future.

Conclusion

This kit is a fairly straightforward build if you have experience with resin materials and are OK with fabricating a couple of fiddly bits. It fills another well-appreciated niche in the realm of factual spaceflight modeling, and keeps my manned launch vehicle collection complete. My kit was purchased directly from RealSpace Models.
