Dragon Flight, X-Train
Flying Launch Coaster,
Ningbo, China
In many industrial sectors, China is
the future market. This is also the
case for the entertainment field in
which the German company Maurer
Söhne is working. The roller coaster
Dragon Flight is being built for
Romon U-Park, an urban theme park
in Ningbo. It is the first X-Train Flying Launch Coaster designed by
Maurer Söhne.
The roller coaster has a length of
504 m. Its seven roller coaster elements include three inversions. The
X-train has a capacity of 20 passengers. With top speeds of 90 km/h,
the train reaches up to 4.5 g (gforce) several times. The opening is
planned for the turn of the year
2014/2015.
Structural System
The base area is 113 m × 51 m. At
the highest point of the coaster ride,
which is called the top hat, a vertex
height of approximately 30 m is
reached. The overall structure consists of a tubular structure with 6,201
members and 86 cross-sections.

Structural Analysis
The rail structure was calculated in
RSTAB. Both model and wheel loads
were directly imported from the
dynamic simulation by using
RS-COM.
The analysis was performed according to Chinese and European standards, including ultimate limit state
design and fatigue design.
The German engineers accessed the
RSTAB results by using RS-COM
again for the fatigue designs. Then,
the design according to EN 1993-1-9
and GB 50017 was carried out with
post-processing programs.
RS-COM was used again to return
the results of the post-processing
programs to RSTAB in order to represent the results graphically on the
rendering of the entire model.
