Bringing people out of the atmosphere into
space, making them discover the scenery
that only astronauts could admire up to now,
the scenery that we can only see through
pictures; such is the aim behind the
conception of the Manned Suborbital
But then, how should we enable the clients
to get into the MSV, and thus begin their
extraordinary experience? How should such
a wondrous journey end?
team wished to propose
a system for the boarding and disembarking
of the passengers of the MSV. Two choices,
made during the preliminary thinking phase,
were determinant factors for the project.
First, the studied system would be
integrated in the structure of the MSV.
Second, the said structure would be based
on the work done by the 2014 Azim’UTBM
For security matters, especially during the
flight phase where passengers experience
weightlessness, the stairs, which are
included in the MSV door, could not remain
as they were. The sought solution was to
articulate the steps. The door would then
present a flat surface once closed, instead
of a reverse stairway.
Moreover, in order to gain mass, the chosen
final design of the steps was a slim
aluminum slab strengthened with stiffeners.
Lastly, it was determined that the most
appropriate sort of stairs would be
alternating tread stairs. This form has the
advantage of being a lot more comfortable
to use when the slope is steep, which is the
case with the MSV: the slope of the stairs is
about 51°. The reason behind this ease of
use is the greater tread depth which is
permitted by this configuration, for the same
rise height. As such, this stairway would not
diminish the magic of the experience, and it
would even add an original touch to it.
